The following issue has been SUBMITTED. ====================================================================== https://cmake.org/Bug/view.php?id=15818 ====================================================================== Reported By: maarten Assigned To: ====================================================================== Project: CMake Issue ID: 15818 Category: CMake Reproducibility: always Severity: text Priority: low Status: new ====================================================================== Date Submitted: 2015-10-28 21:53 EDT Last Modified: 2015-10-28 21:53 EDT ====================================================================== Summary: The variable CMAKE_ASM_OUTPUT_EXTENSION is ignored when creating a compiled file Description: The sdcc compiler has ".asm" extensions for the assembly files. But cmake always assumes the ".s" extension. https://github.com/Kitware/CMake/blob/d288b216af6864567354ccb05e85466fb57d46b0/Source/cmMakefileTargetGenerator.cxx#L802-L803
For a source file 'main.c', 'make help' shows the following targets: ... main.rel ... main.i ... main.s Running 'make main.s' gives the following output: Compiling C source to assembly CMakeFiles/proj1.dir/main.c.s But in the CMakeFiles/proj1.dir, there is no 'main.c.s' file. The generated assembly file is 'main.c.asm' Steps to Reproduce: 1) Create toolchain file with: - CMAKE_SYSTEM_NAME = Generic - CMAKE_ASM_SOURCE_FILE_EXTENSIONS = asm - CMAKE_C_C_CREATE_ASSEMBLY_SOURCE = "<CMAKE_C_COMPILER> <DEFINES> <FLAGS> -E <SOURCE> > <PREPROCESSED_SOURCE>" - set CMAKE_C_COMPILER, CMAKE_FIND_ROOT_PATH, ... 2) Create a basic main.c 3) Create CMakeLists.txt, with - CMAKE_C_FLAGS = "-Werror --model-small -mmcs51 --opt-code-size" 4) Run CMake to generate the makefiles (using the toolchain) 5) Run "make help" (main.s will show up) 6) Run "make main.s" (main.asm will be created instead of main.s) 7) Run "make main.asm" (An error will be shown) Additional Information: A simple sdcc config is attached. ====================================================================== Issue History Date Modified Username Field Change ====================================================================== 2015-10-28 21:53 maarten New Issue ====================================================================== -- 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.
