The following issue has been SUBMITTED. ====================================================================== http://www.cmake.org/Bug/view.php?id=14859 ====================================================================== Reported By: Felix Schwitzer Assigned To: ====================================================================== Project: CMake Issue ID: 14859 Category: CMake Reproducibility: always Severity: minor Priority: normal Status: new ====================================================================== Date Submitted: 2014-04-01 17:53 EDT Last Modified: 2014-04-01 17:53 EDT ====================================================================== Summary: UseSWIG rebuilds source even when the the dependencies have not changed (again) Description: This reopens 0010080, as I'm not the original reporter and therefore can't reopen the bug.
The fix provided in http://cmake.org/gitweb?p=stage/cmake.git;a=commitdiff;h=63ebb1 does not solve the problem of recompiling the python-module again and again, if the module name is passed via set_source_files_properties( ${_interfacefile} PROPERTIES CPLUSPLUS ON SWIG_FLAGS "-DMODULENAME=${_modulename}") The original, reverted, change http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=f0111deb worked for me. Steps to Reproduce: See attached example Additional Information: I build the bindings almost always for different script languages, iterating over the languages and passing a modified modulname appropriate to the selected language in the way mentioned above. A cmake fragment would look like set(_iffile "ltt.i") set(_languages "ruby" "python") foreach(_lang ${_languages}) if(_lang STREQUAL "ruby") set(_modulename "rltt") set(_libs ${RUBY_LIBRARY}) elseif(_lang STREQUAL "python") set(_modulename "pyltt") set(_libs ${PYTHON_LIBRARY}) endif() set_source_files_properties( ${_iffile} PROPERTIES CPLUSPLUS ON SWIG_FLAGS "-DMODULENAME=${_modulename}") swig_add_module(${_modulename} ${_lang} ${_iffile}) swig_link_libraries(${_modulename} ltt ${_libs}) endforeach() ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2014-04-01 17:53 Felix SchwitzerNew Issue 2014-04-01 17:53 Felix SchwitzerFile Added: ltt.zip ====================================================================== -- Powered by www.kitware.com Please keep messages on-topic and check the CMake FAQ at: http://www.cmake.org/Wiki/CMake_FAQ Kitware offers various services to support the CMake community.
