[CMake] how to create library for a folder having only two sub folder
hi all, I am a newbie to cmake. the problem iam facing is like this: actually i hvae a folder which many sub folder. i cretaed a CmakeLists file for very folder and i added them to the root Cmakelist file. now i have successfully created the libraries for all the sub folders but i want a main library to be build for the fodlers for which the separate libraries are already build. Please guide me how to do that. Regards- ankit jain ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
[CMake] error: multiple declaration of main
hi all, in one of my folder i have three files. in each of them a main() function is defined. now on building it says that multiple declaration of main. if i compile the makefile using gcc only no such error had came. Guide me what to do? Regards- ankit jain ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake
[CMake] Include header files at run time through cmake
hi all, i have a c file in a folder which contain the line #include "%h" which says compile the file with -I option with gcc to tell where %h is located. but in cmake as i already add the header files by defining the path through a variable and add it through include_directories command. it still give error on compiling that %h: no such file or directory found. I am not able to understand how to remove it through cmake. regards- ankit jain ___ CMake mailing list CMake@cmake.org http://www.cmake.org/mailman/listinfo/cmake

Re: [CMake] equivalent cmakelist for this file
The objective here to include all the .desc files in the cmakelist and when we make it it should generate the executable for it like if we include abc.desc then after make it should generate a file abc which is executable and a script which has test cases but generated by .desc file only. In order to achieve that guide me how to write cmake list file for it so that it wiil produce equivalent behaviour as normal make does using unix makefiles. When we make to the unix makefiles it is generating the equivalent executable mentioned inthat .desc file. I want to achieve that through Cmakelist files.

Actually the cmakelist file should do: 1. this functionality to create ./abc this file should generate after running make. since this line is written in desc files thats why i write this to you.

Hi all, I have folder f1 having csome cpp files. structure is like this: f1 c1.cpp c2.cpp now i create an executable for it as add_executable(myexe c1.cpp c2.cpp) the path of f1 folder is /home/ankit/mycode/f1 now i want to link myexe to a library lib.so and lib1.a which are not in this folder but resides in other folder suppose in lib whose path is something like this: /home/ankit/mycode/lib/lib.so /home/ankit/mycode/lib/lib1.a How to do achieve this linkage so that no unref came. Right now iam doing it usinmg target_link_libraries by giving the entire path somthing like this: target_link_libraries(myexe /home/ankit/mycode/lib/lib.so /home/ankit/mycode/lib/lib1.a) but it gives some unrefs. i dont know why. Can u tell me how to achieve it.

Hi all,
Actually i am usinf PARENT_SCOPE property but facing some problem.
the directory structure i have is like this
f1
...f2
.f3 (inside f2)
i.e f1 has f2 folder and f2 has f3
in f3 i have demo.cpp file
i set a variable for this file as set(myvar demo.cpp)
Also i did set(myvar1 ${myvar} PARENT_SCOPE)
Due to this now myvar1 should be visible in f2 which has value demo.cpp
now what i want actually is that myvar1 should be visible in f1 but if did
like this in f2:
set(myvar2 ${myvar1} PARENT_SCOPE)
it is not working. i dont know why.
Is iam doing something wrong.

I reasd the documentation realted to add_test and ctest but not getting proper example to clear my doubts. Apart from that i more thing i want to know is that the name of the test we are giving in add_test() command as its first argument is the name of the test that is defined in the executable which we have made.

[CMake] Unlinking a library at run time for an executable
Hi ,
I have defined a variable for a set of libraries that i want to link with
some executables.
But with one executble i dont want to use one of the library from the set of
libraries.
Can i unlink that particular library for this executable since iam using a
variable for all those libraries.
Eg: Folder main Cmakelist
set( var
path/l1.so
path/l1.so
path/l2.so
path/l3.so
path/l4.so
path/l5.so
path/l6.so
path/l7.so
path/l8.so
path/l9.so)
add_subdirectory(f1)
add_subdirectory(f2)
f1
...a1.C
CMakeList for f1 contains:
add_executable(a1 a1.C)
target_link_libraries(a1 ${var})
f2
...a2.C
CMakeList for f2 contains:
add_executable(a2 a2.C)
Now for this i dont want the l9 library. one way is to explicitly link all
the other libraries.
Is there any other way by which i can specifically unlink this library l9 or
say able to link only other libraries.

I am using cmake-2.6.3-RC-14-Linux-i386.
Actually i have a test t1. i want to set and unset LD_LIBRARY_PATH acc.
while adding test t1 so that on running ctest it will use that value of
LD_LIBRARY_PATH rather than using the older set value.
This iam not able to achieve that.
Guide where iam wrong and what need to be done.

[CMake] setting and unsetting already existing enviroment varibale at the time of testing
Hi all, It seems that there is problem existing with setting and unsetting already existing environment variable like LD_LIBRARY_PATH for a particular test. If somebody knows any improvement in that regard please let me know. Actually i want to unset and set the LD_LIBRARY_PATh varibale for my tests it is something like this: add_executable(e1 c1.cpp) add_test(t1 e1) set_tests_properties(t1 PROPERTIES ENVIRONMENT LD_LIBRARY_PATH=)#for setting the library path to empty OR set_tests_properties(t1 PROPERTIES ENVIRONMENT LD_LIBRARY_PATH=/usr/lib) #i.e some other path This thing actually does work with my case. iam using "make test". If iam doing soemthing wrong please let me know or if this thing is in progress of development kindly let me know the alternative that can be done for achieving this thing.

Check your CMAKE_INSTALL_PREFIX path whatever u have set. By default on
linux it is set to /usr/local but if u want it to something else you can set
it in CMakeCache.txt file.
Hope it will work ..

Same thing happens to me also. The problem is of RPATH settings. the path
your cmakelist links to while installing is not set for the sub directories
when you try to build and install it from your main directory "vos".
Therefore you need to do the following:
# use, i.e. don't skip the full RPATH for the build tree
SET(CMAKE_SKIP_BUILD_RPATH FALSE)
# when building, don't use the install RPATH already
# (but later on when installing)
SET(CMAKE_BUILD_WITH_INSTALL_RPATH FALSE)
# the RPATH to be used when installing
SET(CMAKE_INSTALL_RPATH "/bin")
# add the automatically determined parts of the RPATH
# which point to directories outside the build tree to the install RPATH
SET(CMAKE_INSTALL_RPATH_USE_LINK_PATH TRUE)
after doing this once when you do make install it will work and install the
exeutabled in /bin.
No need to set all this variables in the sub directory. it is valid for all
sub dirs.
For further inf. on RAPTH refer this link:
http://www.cmake.org/Wiki/CMake_RPATH_handling
It provide all details pertainign to RPATH settings.
Hope all this will work for you.

I dotn know how to link a library with shell script so that while executing it gets all the supor tof the library which it requires.

Thanks for the reply but iam sorry that you misunderstand my question.
My cmake genrates a library. iam not generating a shel script from cmake.
i already written it. only thing is that iam esxecuting this shell script
through cmake like normal executables. what i want is to link this shell
script with the cmake generated library.
thats it. like we link a cmake generated executable to cmake generated
library.
here the diff. is that the shell script is not generatde by cmake.
Hope its clear.iam giving my folder structure to you.

[CMake] Building java files from cmake
Hi all,
I have a folder "mainfolder" with sufolder "innerfolder" which has soem java
files. i want to create it class files. for that iam using add_sutom_command
to run the javac command but still my class files are not generated.
The content of cmakelist of mainfolder is:
project(mainfolder)
cmake_minimum_required(VERSION 2.4.0)
add_subdirectory(innerfolder)
The content of cmakelist of innerfolder is:
set(
JAVADIST /myjava/jdk/1.4.2/Linux/
XERCESDIR /myjava/XML4J/4.3.4
)
include_directories(${JAVADIST} ${XERCESDIR})
include_directories(${CMAKE_CURRENT_SOURCE_DIR})
set(JAVADIR $(JAVADIST)/bin)
set(
JAVAJRE $(JAVADIST)/jre
JAVAC $(JAVADIR)/javac
JAVA $(JAVADIR)/java
)
set(CLASSPATH
$(CMAKE_CURRENT_SOURCE_DIR):$(XERCESDIR)/xmlParserAPIs.jar:$(XERCESDIR)/xercesImpl.jar)
set(innerfolder_srcs
Myprogram.java
)
ADD_CUSTOM_COMMAND(OUTPUT ${innerfolder_srcs}
COMMAND ${JAVAC} ARGS -classpath ${CLASSPATH}
${innerfolder_srcs}
)
I dont know where iam doing something wrongdue to which class files for the
specifed source java file is not genrated..
Please guide me..

Still it does not work means not creating class files. No errors are
generated but .class files are not genrated.
I feel there might be a problem with CLASSPATH,
But also i try by explicitly set them. It doesnt work.
Check this link:
http://www.mail-archive.com/cmake@cmake.org/msg16764.html
Iam not getting whatever given in this link. How to use it i dont know.

Actually through include directories it is not taking. i have to extract the fiels from the jar and then the library is build otherwise simply including the jar files using include_directories not working. Iam not sure abotu classpath since it is not being set through cmakelist and even when i set it through bash it is not taking those jar files. Can u tell me how to do that with an example. Thanks..

[CMake] problem with add_custom command
hi all,
Iam doing the following through my cmakelist.txt
add_custom_target(mytarget)
add_custom_command(TARGET mytarget POST_BUILD
COMMAND ${CMAKE_COMMAND} -E tar xvf ${CMAKE_CURRENT_SOURCE_DIR}/t1.tar)
this cmakelist is written in subfolder of a mainfolder..
But the problem is that files are not extracted and it is not showing any
error.
Is iam doing something wrong..
Same problem with other where iam extracting jar files
add_custm_target(mytarget1)
add_custom_command(TARGET mytarget1 POST_BUILD
COMMAND jar ARGS -xf $(XERCESDIR)/xmlParserAPIs.jar
WORKING_DIRECTORY ${XERCESDIR})
here i want to extract the files in the smae directory whrer the jar exists.
is iam doing something wrong here too..
add_custom_command with output option doesnot seems to work thats why i go
with this approach
ANy suggestion in this regards will be of great help to me...

I followed this approach becoz add_cutom_command with outptu option deos not
seems to work but actually i want to do it by that way only because from the
main tree i issue make only so thats why that target will not build.
Do anyone know what is the problem if i do like this and then run make:
add_custom_command(OUTPUT {TARDIR}/t2 {TARDIR}/t3
{TARDIR}/t1
COMMAND tar ARGS -xvf $(TARDIR)/mytar.tar
WORKING_DIRECTORY ${TARDIR})
> Here i want to extract the files in the same folder where tar exists..
the extraction will actually should give these t1, t2, t3 folder which i
mention in output ..
Is iam doing something wrong

Thanks for your suggestions it works but the problem is that iam making a
library which requires some source files which will come after extracting it
from tar.
In that making an custom target for it and then add_dependencies to that
library to this custom build target does not solve the purpose.
then how to include those files which is required by the library which came
from tar.

Is there any way by which we just give the name of folder where files has
extracted and add_library command will take it by some means it is becoz if
we dont know what files will be genrated inside that folder or if there are
large no.of files then listing them in OUTPUT is really cumbersome..

[CMake] Why jars not linked to other files directly in cmake
Hi all,, I have seen that only including the directories where jars exist wil not solve the puprose of using those jars. we have to either extract the files from it or either include the directories where the file exists from which jars have been made. If we give that path then what is the need of jars i try to link the jars but its not working . i extract the files and then include them then its working... if somebody works with jars and able to achieve this whatever i have said please let me know.. ankit ___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Follow this link to subscribe/unsubscribe: http://www.cmake.org/mailman/listinfo/cmake

Thanks Rob i checked it again it works now for me actually i run make from
root directory and iam creating a library with some java files listed in my
cmakelist as src but when runnng it from root i need to write
include_directories(${CMAKE_CURRENT_SOURCE_DIR} in sub dir. cmakelist file.
earlier i thought it is not taking jars but actually jars are working fine
and it is not taking files from the sub diretory itselg ..
Generally if we include all files in cmkelist then there is no need to write
above line but mihgt require in java case.
but anyways it works now. thanks for the help..

[CMake] Cmake support for MKS toolkit
Hi all, I am working on windows. I am currently using MKS to build my code without using cmake. but since i dont know whether cmake supports MKS or not iam not able to build my code through cmake using mks. If yes, please can anybody let me know how i can build my code through mks toolkit on windows using cmake. since i dont find as such binaries for mks toolkit specially. I need to do this because if i dont use mks and build code directly using cmake binaries for windows then all the unix functions are not working on windows. i got error of unistd.h not exists and platform not recognised since i define macro for windows as NUTC for mks..

[CMake] Changing the default compiler of VC++
Hi all, Actually I am porting my code on windows but since windows don't understand the unix libraries iam using third party toolkit mks earlier to build the code and linking all the headers and libraries of mksnt. but now i am not using mks and directly building the code using visual studio .net 2003. since VC++ uses cl compiler by defualt i want to change it through cmakelist variable CMAKE_C_COMPILER and CXX variable to the compiler used by mks i.e cxx. But when iam doing so it is still using cl. I am not getting from where it is taking cl complier and not changing to whatever i want. It might feel auckward to some of you that why iam changing to mks compiler becuase iwant to check my code whether without opening mks bash if iam direclty using its compiler will it work or not.. I request you all to tell me how it can de done so that my VC++ takes cxx compiler of mks toolkit rather its default cl compiler... why changing cmake variable doesnot have any effect on it that i mentioned above for compiler...

I already build the code using mks. now i want to build the code using cl/VC++. since it gives lots of errors of not founding fiels like strings.h unistd.h so i thought its good to link it with mks compiler and give path to the libraries and header used my mks for windows.. i hope you got it..

[CMake] CMake, MKS and VC++
Hi all, I build me code without cmake through mks on windows... it is successful.. Now i want to build my code through cmake on mks for windows. The project is compiling but like other OS's it is not generating Makefile so on doing make it says error: Make no target... So guide me how to proceed.. I also tried with VC++ directly to build the code but it seems to give lots of error since i feel it have problem with nutcracker which i used in code for windows and also i think not able to link some DLL but not sure since on mks i compile with one definition as -D__NUTC_DLL__ ... It is because VC++ uses cl compiler not cxx compiler of mks.. This is what i think but iam not sure of anything... You people guide the right way that helps me in building the code using cmake with mks through VC++... Also if any settings are required for VC++ tell me so that i configure that acc. I struggled a lot with VC++ for building code thorugh cmake. My code is configured properly but on running it gives lots of error... Any help in this regard really helps me a lot..

[CMake] Settings different compile options for diff. files in same folder..
Hi all,
I have a folder in which there are 5 files
folder
a1.c
a2.c
a3.c
a4.c
a5.c
Out of these from 4th and 5th iam making a library if iam working on windows
else with the rest three iam building one library for the folder.
Even on windows also iam making this library but making one more library for
the files 4th and 5th.,.
Problem:::
Now the problem is that for the first three files i set certain macros and
certain CXX compile flags.
But for the 4th and 5th files i need not want these settings..
I want no macros and only two diff. compile flags /clr and /MD for compiling
these files and certain things for linking like /STCAK:value /NOENTRY
/NODEFUALTLIB:value
But when i am settings these using the set_source_files_properties the older
properties also exists there. they are not removed..
I dont understand how to remove old one and set new settings for these files
only,
Remember iam working on windows.(Visual studio .NET 2003)
when iam setting /clr /RTC will not be there but since it is set earlier it
is not removed i dont know why...
One more problem is there that is set the properties of files through the
set_source_files_properties and suppose i want to set two flags while
compiling like this:
set_source _files_properties(${source} PROPERTIES COMPILE_FLAGS /clr;/MD)
it does not taking it.. only one flag iam able to set not multiple flags..
One example if you give will give me great help..
Can anybody let me know how to do all these...
If any clarification required please let me know..

ankit jain

[CMake] unable to include a source file for all sub directories
Hi all,
My problem is like this...
My source tree structure is:
Main_folder
.. Ident.c
..folder1
f11.c
f12.c
..folder2
..f21.c
..f22.c
..folder3
f31.c
f32.c
Now iam building a library for main_folder as:
foreach(fname ${folder1_srcs}
list(APPEND main_folder_srcs folder1/${fanme})
endforeach(fname)
foreach(fname ${folder2_srcs}
list(APPEND main_folder_srcs folder2/${fanme})
endforeach(fname)
foreach(fname ${folder3_srcs}
list(APPEND main_folder_srcs folder2/${fanme})
endforeach(fname)
list(APPEND main_folders_srcs Ident.c)
add_library(mylib SHARED ${main_folder_srcs})
Now I am able to get all the source files from all the folders. but the
problem is that all folder source files uses one variable v1 of this Ident.c
file..
So the error iam getting while building the library is :
unresolved external symbol: v1 (iam working on windows VC++)
I am not getting why the sub directories are not able tio extract that
variable v1 from the Ident.c file
Is my way of including the file is wrong..
Please tell what should i do so that the sudirectories files are able to
acccess that varaible v1 from file Ident.c which is outside it as mentioned
in above tree structure...

[CMake] unable to include a source file for all sub directories

If suppose 5 files are there in one folder and each file uses some functions form other file in the same folder and when ur creating library then there is no problem.. Issue is if one folder file uses another file which is in diff. folder or in its parent folder then creating library creates problem and giving error as unresolved symbols. since iam building through cmake and i used the already said method of how iam adding sources for the libraries form the sub folders i think my way of including files is somewhat wrong or iam missing somethign duet o which those files are not able to take the support that file... I hope i add some clarification in this regard.

Eg:
main
...Ident.c
folder1
...f11.c
...f12.c
...folder2
..f21.c
..f22.c
Now if this Ident.c is there in each folder1 and folder2 then it works
well.. but since it is outside folder1 and fodler2 so while linking neither
f11 f12 f21 f22 will be able to link Ident.c
iam making library main as:
...CMakeLists of main folder.
foreach(fname ${folder1_srcs})
list(APPEND main_srcs folder1/${fname})
endforeach(fname)
foreach(fname ${folder2_srcs})
list(APPEND main_srcs folder2/${fname})
endforeach(fname)
list(APPEND main_srcs Ident.c)
add_library(main SHARED ${main_srcs})
CMakelist of folder1...
set(folder1_srcs f11.c f12.c)
set(folder1_srcs ${folder1_srcs} PARENT_SCOPE)
CMakelist of folder2...
set(folder2_srcs f21.c f22.c)
set(folder2_srcs ${folder2_srcs} PARENT_SCOPE)
Now all files iam getting from folder1 and folder2 and objects of all files
including Ident.c is created... But while linking f11.obj f12.obj f21.obj
f22.obj all show error undefined symbol:
char *v1
where Ident .c contains..
char v1[]="Hello";
I this example give you idea what iam trying to do...

Thanks for the suggestion David but ht eproblem is still there. i will give
you the content of two files with the tree structure. i request you to do
the same for me on your machine and see whether it gives error or not..
mainfolder
...Ident.c
...subfolder
.file.c
Ident.c contain:
int number=10;
char array[]="hello";
subfolder/file.c contains:
#some header files
extern int number;
print("iam in sub folder");
Now cmakelists of mainfolder is:
Project (mainfolder)
foreach(fname ${subfolder_srcs})
list(APPEND mainfolder_srcs subfodler/${fname})
endforeach(fname)
list(APPEND mainfolder_srcs Ident.c)
add_library(mylib SHARED ${mainfolder_srcs})
CMakelist of subfolder..
set(subfolder _srcs file.c)
set(subfodler_srcs ${subfolder_srcs} PARENT_SCOPE)
Thats it..
Compiling is ok .. Ident.obj and file.obj created..
But when it creating mylib library in linking it says:
file.obj : unresolved external symbol: int number
if the tree structure is like this:
mainfolder
Ident.c
file.c
Means no subfolder direct file in mainfolder. then there is no problem in
creating the library.
Because of accessing file from subfolder it creates problem..
Also if in VC++ if i give addtional option in compilation as /FI"filepath to
Ident.c"
Then it works..
because file.c is compiled with Ident.c
so it works but i dont want to give this flag in compiler option...
Why it is not taking directly...
I hope i make my question very clear...

Ankit Jain..

I made the changes above can u run this code for me and let me know whether
it is working or not.
i commented the line which are not there in my code. Also here var.h is not
exits since code of var.h is directly there in main.c..

[CMake] Linking object file with executable
Hi all,
My Cmakelists contains:
set(myobj ${CMAKE_CURRENT_SOURCE_DIR}/../objfolder/myfile.obj)
add_executable(myexe main.c ${myobj})
This myfile.obj object file is generated while building objfolder before
creating this executable
Now on building this executable i got a warning:
main.obj: warning: earlier declaration of a function f1() found in
myfile.obj: second definition ignored..
This means it is taking the f1() function from myfile.obj but i want f1()
function to be taken from main.obj..
What to do?
Also it is imp. to link this myfile.obj file to myexe executable since it
depends on other functions of this object file..
So this object file has to be there.
Just tell me how function f1() can be taken from main.c rahter than from
myfile.obj evenif it still gives warning as:
myfile.obj:warning: earlier definition of function f1() found in main.c
(since if it takes f1() from main.c): second def. ignored

Ankit Jain

It gives error as myfile.obj.lib not found..
Since it is not library it is not valid to give like this...

[CMake] Want to compile a file but does not want to link it in library
Hi all, I have a folder f1 having 4 files c1.c c2.c c3.c c4.c. Now iam compiling all these files with certain definitions and other compiler flags. Now what i want is that when iam building library for this forder f1 it does not take c4.c One way is that i should not include this file in creating library.In that case c4.c willnot be compiled but i want c4.c to compile but not be included in the library. Also if i use add_custom_command to compile that file explicitly then i have to give all the definitions and other compiler option settings for that file explicitly which i dont want to do.. Is there any option in cmake while creating library which allows compiling a file but not linking it in library.
