| Summary | 0014532: CMake internal error: cmTarget::GetOutputInfo | ||||||||
| Description | I created an object library and then attempted to reference the target in a custom command using $<TARGET_FILE:tgt>. This caused the following: cmTarget::GetOutputInfo called for my_obj which has type OBJECT_LIBRARY This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information. System error 768. | ||||||||
| Steps To Reproduce | Using CMake for Win32 on Windows 7 x64 Create an object target: add_library(my_obj OBJECT my_src.cpp) Use the object target in a shared library: add_library(my_lib SHARED $<TARGET_OBJECTS:sc_lo_obj> my_lib.rc) Attempt to copy the object target using a custom command (a post build command on the library): add_custom_command (TARGET my_lib POST_BUILD COMMAND ${CMAKE_COMMAND} -E copy $<TARGET_FILE:my_obj> ${OUTPUT_DIR}/my_obj_renamed.obj ) | ||||||||
| Additional Information | I was looking for a way to copy an object file from the intermediate directory to a directory of our choosing. Seeing the OBJECT library option, I figured I'd give this a shot to see what would happen. | ||||||||

Thanks for the report. Crash replaced with error message and test case added: http://cmake.org/gitweb?p=cmake.git;a=commitdiff;h=d9605897 [^] The $<TARGET_FILE:...> generator expression does not make sense for object libraries because there is no "library" file and there can be many object files. As for your original objective, to copy an object file, that will require a new CMake feature to do portably. It may be tricky when it comes features like CMAKE_OSX_ARCHITECTURES that end up with more than one object file per source file (one per architecture per source). Currently object files are not first-class objects in IDE build tools (VS, Xcode) so it is hard to make them first-class objects for CMake. Anyway, this feature is beyond the scope of this issue tracker entry. |
