Re: [CMake] works when I build using XCode, but not with CMake makefile
Hi Mr Candy (I am still getting a heck out of cottoncandycoder, sorry :D ) 1) the way you do it, is not really the way cmake should be used AFAIK. > In my CMakeLists.txt file I included: > set( CMAKE_CXX_FLAGS "-L/Applications/MAMP/Library/lib -lmysqlclient > -lpthread -lz" ) > set( CMAKE_EXE_LINKER_FLAGS "-lmysqlclient -lpthread -lm -lz" ) change this to: #I assume you have something like this somewhere add_executable(my_exe_name SOURCES my_exe_name.???) #here comes the "magic" link_directories(/Applications/MAMP/Library/lib) target_link_libraries(mysqlclient pthread m z) In theory, if all those dependencies are available at cmake-invocation, this should emit compiler calls that produce your binary and link mysqlclient into it (by default with using RPATH, see the docs on this: https://cmake.org/cmake/help/v3.0/prop_tgt/MACOSX_RPATH.html#prop_tgt:MACOSX_RPATH ). Depending on whether you wanna distribute your binary and cannot be sure if (at build time) pthreads etc are available, there are cmake find modules for pthreads and libz (FindThreads, FindZLIB) which you can use. libm should come with the libc of the system AFAIK. I also just checked but up to cmake 3.5, there is no MYSQL Find module. Which is kinda sad as there is a FindPostgreSQL module. :( If there would be, you could use it in a (hopefully) platform independent way and not bother with finding the right paths to libmysqlclient. 2) The compiler flags you posted do not explain, why Xcode apparently sets the rpath inside the binary and your cmake script doesn't (haven't seen the full CMakeLists.txt of your project yet). I hope the above gets you going. @cmake developers: it would be nice to have more obvious pointers to cmake example projects like an example SDK or so. If there is, please let me know. I only found this: http://www.vtk.org/Wiki/CMake/Examples#Finding_Packages but that's tied to vtk.

Aaron, it's about the way that you compile your binary and link libmysqlclient into it. I guess (@all: please correct me if I am wrong) as I don't know how you use cmake to build your libraries/binaries, that you don't set the rpath of libmysqlclient inside your binary. Doing so will ensure that the absolute path of libmysqlclient is stored into your binary, so that the runtime environment can pick it up and use (keeping fingers crossed that the path is still valid). The alternative to doing so, is linking against the static version of libmysqlclient (which comes at a cost on another front as well).

Re: [CMake] CUDA: COMPILE_DEFINITIONS not picked up
Karl, good question. The docs say that you supply OPTIONS to cuda_add_library, which are in turn handed over to cuda_wrap_srcs. the only chance I see is digging there. internally, both cuda_add_xxx create regular cmake targets. I am not sure why cmake doesn't accept subsequent set_target_properties calls on them. I cannot spare the time resources to dive into this further. Sorry! Maybe it's worthwhile to file a bug report and bring that to the attention of the FindCUDA.cmake author?

It does indeed work if I define them explicitly like that, but the reason why I want to use something like COMPILE_DEFINITIONS is that we have a large library that has several targets with different setups (release and debug mode, for instance). Most of the library is regular C++ and there the COMPILE_DEFINITIONS propagates to all source files. Now I want it to propagate to any CUDA .cu files too.

AFAIK, there is also a global CMAKE_POSITION_INDEPENDENT_CODE that is used to derive the target-specific value of POSITION_INDEPENDENT_CODE.

Re: [CMake] Fwd: Re: cmake needs 2 runs to find boost
Hi to all, {sorry for the email mess, anyway here is my to answer to Andreas
as it affects this mail thread)
thanks for the Boost_DEBUG hint. The output is much more concise and
digestible than "--trace".
Good News: It works now. I discovered I had a cmake Windows build installed on
the machine that the MSYS2 terminal picked up. Once that was removed and I
used the msys internal cmake, it works out nicely. However, the MSVS
build target is gone now. So I have to find a way to use either version in
parallel somehow.
Bad News: I didn't follow through why the problem occurred in the first place.
Once thing is for sure, the FindBoost module acutally triggered BOOST_FOUND=1!
But finding the actual libraries of boost failed.
Best,
Peter

Re: [CMake] cmake needs 2 runs to find boost
Hi to all, ok, I tried the attached minimal CMakeLists.txt again and found out that it fails in the way I described only with the "MSYS Makefiles" generator. If I use the same CMakeLists.txt without a custom generator (so MSVS is the default IIRC), the libraries are found alright! Any ideas?

[CMake] cmake needs 2 runs to find boost
Hi to all,
I tested this with cmake 3.2.2 and 3.3.2 and still get the same problem.
I'd like to use boost with gcc on windows 7 64bit. I installed boost and gcc
with msys2 as I cannot use MSVC for the actual project I am looking into for
this.
the funny thing, if I use the attached CMakeLists.txt on the machine and call:
```
$ cmake -G "MSYS Makefiles" -DBOOST_ROOT=C:/msys64/mingw64 -
DBOOST_LIBRARYDIR==C:/msys64/mingw64/lib ..
-- The CXX compiler identification is GNU 4.9.2
-- Check for working CXX compiler: C:/msys64/usr/bin/g++.exe
-- Check for working CXX compiler: C:/msys64/usr/bin/g++.exe -- works
-- Detecting CXX compiler ABI info
-- Detecting CXX compiler ABI info - done
-- Detecting CXX compile features
-- Detecting CXX compile features - done
setting win specific stuff
CMake Error at C:/Program Files

Unable to find the requested Boost libraries.
Boost version: 1.57.0
Boost include path: C:/msys64/mingw64/include
Could not find the following static Boost libraries:
boost_filesystem
boost_system
No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
directory containing Boost libraries or BOOST_ROOT to the location of
Boost.

I'd like to link statically to multithreaded libboost_*-mt.a from my app. But
it proofes really hard to find Boost in the first place.
Any ideas?
