I’m doing cross compiling with CMake and all is OK but the CMAKE_AR options.
I use set(CMAKE_AR ${GCC_PATH}/dld) to set CMAKE_AR. But I don’t know how to set its option. By default, it uses the options rc to create the archive. But I need to change it to be -X -r5 -o. When use rc, it will complain the file rc cannot be found.
How do I fix it?
It looks like the flags “crs” are hardcoded in the command for creating an archive. There’s no way to override just the flags; you have to rewrite the whole command, like this:
There’s also a
CMAKE_C_ARCHIVE_APPEND(and CXX equivalent) used when the number of objects exceeds the command line maximum, it passes just the “r” flag to CMAKE_AR. You may have to change that one too, see https://cmake.org/cmake/help/latest/variable/CMAKE_LANG_ARCHIVE_CREATE.html
