The following occurs with CMake on Windows, crosscompiling with ARMCC. If the path contains "@", CMake ignores response file in the toolchain file: SET( CMAKE_C_USE_RESPONSE_FILE_FOR_OBJECTS 1 )
The linker command is too long and fails. The command is run in Jenkins, I have not seen a way to avoid generating @ in the path A workaround could be to patch rules.ninja to add the rsp_file handling if missing. Any configuration changes that resolves the problem? Any hints how to debug and fix CMake for this? /Gerhard --------------------------------------- Run in Cygwin, using Windows binary (to use with Windows compiler) "c:/Tools/CMake/3.11.2/bin/cmake" -G "Ninja" --no-warn-unused-cli -DCMAKE_TOOLCHAIN_FILE=toolchain.cmake .
