[CMake] getting undefined error to my own libs.
hello. I'm writing a c++ program that uses three shared libs that I wrote, for some reason, when it gets to the main cpp file, it fails with undefined error. here is the error report: Linking CXX executable ../build/ossm cd /home/dagg/workspace/OSSM/src && /usr/bin/cmake -E cmake_link_script CMakeFiles/ossm.dir/link.txt --verbose=1 /usr/bin/c++ -fPIC CMakeFiles/ossm.dir/COssm.cpp.o -o ../build/ossm -rdynamic ../build/libs/libDataObjects.so ../build/libs/libUtilities.so ../build/libs/libThreads.so ../build/libs/libUtilities.so -lboost_thread-mt -lboost_unit_test_framework-mt -Wl,-rpath,/home/dagg/workspace/OSSM/build/libs CMakeFiles/ossm.dir/COssm.cpp.o: In function `Ossm::cleanUp()': /home/dagg/workspace/OSSM/src/COssm.cpp:33: undefined reference to `Array::Array(int)' /home/dagg/workspace/OSSM/src/COssm.cpp:35: undefined reference to `Array::operator[](int)' /home/dagg/workspace/OSSM/src/COssm.cpp:39: undefined reference to `Array::operator[](int)' CMakeFiles/ossm.dir/COssm.cpp.o: In function `~World': /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' CMakeFiles/ossm.dir/COssm.cpp.o: In function `Ossm::cleanUp()': /home/dagg/workspace/OSSM/src/COssm.cpp:44: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/COssm.cpp:44: undefined reference to `Array::~Array()' CMakeFiles/ossm.dir/COssm.cpp.o: In function `~World': /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' /home/dagg/workspace/OSSM/src/DataObjects/CWorld.hpp:30: undefined reference to `Array::~Array()' ./build/libs/libThreads.so: undefined reference to `boost::iostreams::detail::bzip2_base::~bzip2_base()' ./build/libs/libUtilities.so: undefined reference to `DataFactory::~DataFactory()' ./build/libs/libDataObjects.so: undefined reference to `Array::Array()' ./build/libs/libUtilities.so: undefined reference to `Array, std::allocator > >::operator[](int)' ./build/libs/libUtilities.so: undefined reference to `Array::size() const' ./build/libs/libDataObjects.so: undefined reference to `Array::Array()' ./build/libs/libUtilities.so: undefined reference to `Array::Array(int)' ./build/libs/libUtilities.so: undefined reference to `Array::~Array()' ./build/libs/libUtilities.so: undefined reference to `Array::size() const' ./build/libs/libThreads.so: undefined reference to `vtable for StaffSaverThread' ./build/libs/libUtilities.so: undefined reference to `vtable for Utils' ./build/libs/libDataObjects.so: undefined reference to `Array::Array(int)' ./build/libs/libUtilities.so: undefined reference to `Array, std::allocator > >::size() const' ./build/libs/libDataObjects.so: undefined reference to `Array, std::allocator > >::

Re: [CMake] getting undefined error to my own libs.
hello Eric, thanks for the response. I'd like to solve the Array issue first, then the boost because I have a feeling it is a different one because when I disable the relevant code it doesn't generates the error even when other parts of the program (such as the threadpool). here are the array files content: http://codepad.org/klDWMowB beside a strange typo that I've done, I don't thing I've miss configured it somehow.

[CMake] Overriding read-only project's CMakeLists.txt
Where can I put build instructions that are build-host-wide, not project-wide? I'm relatively new to cmake. I want to "inject" some code before the project's own script, and I'd prefer not to modify the project (since then I'd have to maintain the patch). I want to set the CMAKE__PREFIX variables based on the version of Visual Studio used and whether it's a debug or release build. (I've been given code to do this on the VTK list, but I don't see how to use it apart from editing VTK's file.) ___ 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

This way I believe you can inject these variables. This was discussed recently (in the last 2 to 3 weeks) on the list. Also I think you can pass these on the command line via a batch file that calls cmake or cmake-gui for the user.

I'm trying to refrain from using that because it can bloat up the executable size... unless you can tell me otherwise. in general the program will be compiled using g++ for now, maybe I'll add support for windows compiler later. also, I'm trying to keep the definitions to the header files and the code to the src files.

Re: [CMake] compiling single source with different flags
Not as a "real" solution, but more as a "workaround", you could create a "derived source file" which is just a copy of the source file and then you would have two separate files to be compiled with the appropriate flags.

Thus shouldn't any policy changes make within process_dashboard() be OK and not

[CMake] example how to find a library with PKG_CHECK_MODULES and FIND_PACKAGE_HANDLE_STANDARD_ARGS
according to
Notes to authors of FindXXX.cmake files
We would like all FindXXX.cmake files to produce consistent variable
names.
Please use the following consistent variable names for general use.
XXX_FOUND :
Set to false, or undefined, if we haven't found, or don't want to use
XXX.
XXX_YYY_FOUND :
If False, optional YYY part of XXX sytem is not available.
XXX_INCLUDE_DIRS :
The final set of include directories listed in one variable for use by
client code. This should not be a cache entry!
XXX_LIBRARIES :
The libraries to link against to use XXX. These should include full
paths. This should not be a cache entry!
XXX_LIBRARY_DIRS : Optionally
The final set of library directories listed in one variable for use by
client code. This should not be a cache entry!
XXX_DEFINITIONS :
Definitions to use when compiling code that uses XXX.
Note
This really shouldn't include options such as (-DHAS_JPEG) that a
client source-code file uses to decide whether to #include .
Too, it must not include any compiler flags like -O3 -Wall to be tool
independent!
A FindXXX.cmake module will typically be loaded by the command:
FIND_PACKAGE(XXX [major[.minor[.patch[.tweak [EXACT]
[QUIET] [[REQUIRED|COMPONENTS] [components...]])
If any version numbers are given to the command it will set the
following variables before loading the module:
XXX_FIND_VERSION = full requested version string
XXX_FIND_VERSION_MAJOR = major version if requested, else 0
XXX_FIND_VERSION_MINOR = minor version if requested, else 0
XXX_FIND_VERSION_PATCH = patch version if requested, else 0
XXX_FIND_VERSION_TWEAK = tweak version if requested, else 0
XXX_FIND_VERSION_COUNT = number of version components, 0 to 4
XXX_FIND_VERSION_EXACT = true if EXACT option was given
If the find module supports versioning it should locate a version of
the package that is compatible with the version requested. If a
compatible version of the package cannot be found the module should
not report success. The version of the package found should be stored
in "XXX_VERSION..." version variables documented by the module.
If the QUIET option is given to the command it will set the variable
XXX_FIND_QUIETLY to true before loading the FindXXX.cmake module. If
this variable is set the module should not complain about not being
able to find the package.
If the REQUIRED option is given to the command it will set the
variable XXX_FIND_REQUIRED to true before loading the FindXXX.cmake
module. If this variable is set the module should issue a FATAL_ERROR
if the package cannot be found. For each package-specific component,
say YYY, listed after the REQUIRED option a
variableXXX_FIND_REQUIRED_YYY to true.
The set of components listed after either the REQUIRED option or the
COMPONENTS option will be specified in a XXX_FIND_COMPONENTS variable.
This can be used by theFindXXX.cmake module to determine which sub-
components of the package must be found.
If neither the QUIET nor REQUIRED options are given then the
FindXXX.cmake module should look for the package and complain without
error if the module is not found.
Tip
To get this behaviour you can use the
FIND_PACKAGE_HANDLE_STANDARD_ARGS() macro, as an example see
FindLibSmi.cmake.
# - Find LIBSMI
# Find the native LIBSMI includes and library
# This module defines
# LIBSMI_INCLUDE_DIR, where to find smi.h, etc.
# LIBSMI_LIBRARY, the LIBSMI library with full path.
# LIBSMI_FOUND, If false, do not try to use LIBSMI.
# also defined, but not for general use are
# LIBSMI_LIBRARIES, The libraries needed to use LIBSMI.
# LIBSMI_LIBRARY_DIRS, where to find the LIBSMI library.
# LIBSMI_DEFINITIONS - You should add_definitons($
{LIBSMI_DEFINITIONS}) before
# compiling code that includes netsnmp library
files.
INCLUDE(FindPkgConfig)
IF (PKG_CONFIG_FOUND)
IF (LIBSMI_FIND_REQUIRED AND LIBSMI_FIND_VERSION)
SET(_PACKAGE_ARGS libsmi>=${LIBSMI_FIND_VERSION} REQUIRED)
else ()
SET(_PACKAGE_ARGS libsmi)
ENDIF ()
PKG_CHECK_MODULES(LIBSMI ${_PACKAGE_ARGS})
ENDIF (PKG_CONFIG_FOUND)
SET(LIBSMI_DEFINITIONS ${LIBSMI_CFLAGS_OTHER})
FIND_PATH(LIBSMI_INCLUDE_DIR smi.h HINTS ${LIBSMI_INCLUDE_DIRS})
FIND_LIBRARY(LIBSMI_LIBRARY NAMES smi HINTS ${LIBSMI_LIBRARY_DIRS})
IF (NOT PKG_CONFIG_FOUND)
SET(LIBSMI_LIBRARIES smi)
GET_FILENAME_COMPONENT(LIBSMI_LIBRARY_DIRS ${LIBSMI_LIBRARY} PATH)
ENDIF (NOT PKG_CONFIG_FOUND)
# handle the QUIETLY and REQUIRED arguments and set LIBSMI_FOUND to

# listed variables are TRUE

[CMake] Dependency scanning for non-supported languages?
What's the recommended way in CMake to do automated dependency generation for languages that aren't directly supported by CMake? Suppose my compiler generates an output file which contains a list of all the source files that were used to make it, and I have some tool that can extract this information. Is there some way I can get CMake to use this information in subsequent builds? -- -- Talin ___ 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
[CMake] Question about dependencies and paths
I've got a problem that has been vexing me for several months: It seems that
when I create a custom rule using add_custom_command, the DEPENDS clause
sometimes works and sometimes doesn't, and I can't figure out why.
Here's what my custom rule looks like:
# Link with stdlib
string(REGEX REPLACE ".tart\$" ".s" ASM_FILE "${SRC_FILE}")
add_custom_command(OUTPUT ${ASM_FILE}
COMMAND tartln -disable-fp-elim -filetype=asm ${TARTLN_OPTIONS}
${BC_FILE}
"${PROJECT_BINARY_DIR}/stdlib/stdlib.bc"
"${PROJECT_BINARY_DIR}/libext/testing/testing.lib.bc"
DEPENDS "${BC_FILE}" tartln stdlib testing.lib
COMMENT "Linking Tart bitcode file ${BC_FILE}")
Now, the targets 'stdlib' and 'testing.lib' are almost identical in
definition, however when I attempt to execute this rule it complains that it
can't find a rule to build 'testing.lib'. However, I can make both stdlib
and testing.lib manually by typing "make stdlib" or "make testing.lib"
respectively on the command line. So I know that both targets work.
The only significant difference between the two targets, as far as I can
tell, is that the testing.lib target is one level deeper in the build
hierarchy. That is, in my top-level CMakeLists.txt file, I include the
subdirectories "stdlib/" and "libext/testing/", which contain the
CMakeLists.txt for the two libraries.
I've tried putting $PROJECT_BINARY_DIR and $CMAKE_BINARY_DIR in front of
testing.lib, neither of which seems to make any difference. I've also tried
depending on the actual build product (testing.lib.bc) rather than the
abstract target testing.lib. Still no luck.
Can anyone suggest something else to try?
