Re: [CMake] SWIG python3
Ok the error is related to my arch linux.
Cmake can't find python 3.2 because the lib is named "libpython3.2mu".
Does anybody know about this and perhaps has a solution?

[CMake] SWIG python3
Hi,
I'm trying basic examples for using SWIG to generate python extensions
for c++:
cmake_minimum_required(VERSION 2.8)
FIND_PACKAGE(SWIG REQUIRED)
INCLUDE(${SWIG_USE_FILE})
FIND_PACKAGE(PythonLibs)
INCLUDE_DIRECTORIES(${PYTHON_INCLUDE_PATH})
INCLUDE_DIRECTORIES(${CMAKE_CURRENT_SOURCE_DIR})
SET(CMAKE_SWIG_FLAGS "")
SET_SOURCE_FILES_PROPERTIES(number.i PROPERTIES CPLUSPLUS ON)
SET_SOURCE_FILES_PROPERTIES(number.i PROPERTIES SWIG_FLAGS
"-includeall")
SWIG_ADD_MODULE(number python
number.i number.hpp number.cpp)
SWIG_LINK_LIBRARIES(number ${PYTHON_LIBRARIES})
This CMakeLists.txt is working fine, but only for python2, when I try to
import it in python3, I'll receive the following error:
Traceback (most recent call last):
File "", line 1, in
File "number.py", line 26, in
_number = swig_import_helper()
File "number.py", line 22, in swig_import_helper
_mod = imp.load_module('_number', fp, pathname, description)
ImportError: dynamic module does not define init function
(PyInit__number)
Could someone help me out here?
Thanks,
Matthias

Thank you for this hint, didn't know that I don't this.

Yes without that one, my programs weren't able to find
the headers without using full / relative paths.
Thank you

Re: [CMake] Static lib in project
It's working now - just had a typo inside the names.
Thanks @all.

Re: [CMake] Static lib in project
Have the following problem:
the lib is linked, but my testprogram can't link against it,
because it's not found:
Built target
aclibconfg
/usr/lib/gcc/x86_64-pc-linux-gnu/4.5.3/../../../../x86_64-pc-linux-gnu/bin/ld:
cannot find -ltestlib
collect2: ld returned 1 exit status
make[2]: *** [src/test/test] Error 1
make[1]: *** [src/test/CMakeFiles/test.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs
I've already added the directories to my target, but still not working:
src/test/CMakeLists.txt
add_executable(test main.cpp)
link_directories(
${CMAKE_BINARY_DIR}/src/testlib
)
include_directories(
${CMAKE_SOURCE_DIR}/src/testlib
)
target_link_libraries(test testlib)
The lib is build under src/testlib/testlib.a
Any help would be really nice !
BR,
Matthias

[CMake] Static lib in project
Hi, could anybody give me a hint or an example on how to use a static lib inside a project? I need to create a static lib, which is only used inside a project for different executables. Let's say a project like the following: src static_lib lib.cpp lib.hpp executable1 main.cpp executable2 main.cpp The lib should be static and used only inside this project. I hope I could make it clear :) Thanks and best regards, Matthias signature.asc Description: This is a digitally signed message part -- 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
