Hello,
I'm stuck on trying to use the generated lm_new.obj file in Windows with a CMake-based codebase.
I'm generating lm_new with nmake on Windows with:
nmake -f makefile clean all
Then I copy over the lm_new.obj file. In my CMakeLists.txt I include the lm_new.obj file with:
set(REVENERA_OBJS
${CMAKE_CURRENT_SOURCE_DIR}/lm_new.obj
)
add_executable(our_executable ${REVENERA_OBJS} lm_heat_runner.c)
set_source_files_properties(
${REVENERA_OBJS}
PROPERTIES
EXTERNAL_OBJECT TRUE
GENERATED TRUE
)
When I run mingw32-make I get:
[100%] Linking C executable ..\..\our_executable.exe
ld.exe: CMakeFiles\heat_licensing_runner.dir/objects.a: member CMakeFiles\heat_licensing_runner.dir/objects.a(lm_new.obj) in archive is not an object
collect2.exe: error: ld returned 1 exit status
If I take out the usage of lm_new.obj in our CMakeLists.txt file I get a lot of undefined references:
(.text.startup+0xa3): undefined reference to `l_n36_buf'
(.text.startup+0xc3): undefined reference to `lc_new_job'
(.text.startup+0xf7): undefined reference to `lc_set_attr'
(.text.startup+0x130): undefined reference to `lc_checkout'
(.text.startup+0x1b9): undefined reference to `lc_checkin'
(.text.startup+0x1c6): undefined reference to `lc_free_job'
(.text.startup+0x1f8): undefined reference to `lc_perror'
(.text.startup+0x205): undefined reference to `lc_get_errno'
So my question is this: How should I be building and linking these? Or is it even possible to build in nmake and link to the output in MinGW?

I was able to get things working by reversing the process and DLL wrapping the library from MinGW for use with a modified build step in the Revenera makefile.
