Hi CMake developers, I've been trying to modify my previous cross compiler support work to fit into the new development scheme of tool chain support with CMAKE_TOOLCHAIN_FILE that is in the current development CVS tree.
I've defined CMAKE_TOOLCHAIN_FILE to point at my tool chain specific cross compiler information, including compiler flags etc. To make CMake configure successfully I had to define the following: -DCMAKE_TOOLCHAIN_FILE:string=Toolchain-Freescale-HC12 (1) -DCMAKE_C_COMPILER_ID_RUN:bool=TRUE (2) -DCMAKE_C_COMPILER_WORKS:bool=TRUE (3) (1) Does anyone have a proposed convention for naming extension tool chains? I would suggest "Toolchain-<Vendor>-<Arch>" Is the intention that I should have to define (2) and (3)? It would be nicer to have a cleaner way to turn of the compiler self-testing which is being caused by trying to determine the compiler ID, I would assume this is the intention of CMAKE_CROSSCOMPILING which doesn't seem to be being used anywhere yet? I had to patch CMakeTestCCompiler.cmake to stop it from trying to determine the type size for "void *" (without this I got an error saying that TRY compiles weren't allowed for cross-compiling!) IF (NOT CMAKE_CROSSCOMPILING) CHECK_TYPE_SIZE("void*" CMAKE_SIZEOF_VOID_P) ENDIF (NOT CMAKE_CROSSCOMPILING) I at least managed to get my code compiling, but currently linking isn't working, I'll look at this when I have more time. Anyway, as a first attempt it was fairly painless to get the cross compiling going (much easier than having to patch the system <g>). - TrevK
