I assume you are installing your warez into $HOME. You would use --prefix=$HOME when configuring. So binaries are in $HOME/bin, libraries are in $HOME/lib, etc. Use -fdebug-prefix-map as an option to CFLAGS and CXXFLAGS like so: -fdebug-prefix-map=${PWD}="${HOME}/src/gpu-simulator" Then, after configure, make and make install, execute the script: # run from the gpu-simulator directory, where you configure bash copy-sources.sh "${PWD}" "${HOME}/src/gpu-simulator" Here's the copy-sources.sh script: $ cat copy-sources.sh #!/usr/bin/env bash src_dir="$1" dest_dir="$2" if [[ -z "${src_dir}" ]]; then echo "Please specify a source directory" exit 1 fi if [[ ! -d "${src_dir}" ]]; then echo "Source directory is not valid" exit 1 fi if [[ -z "${dest_dir}" ]]; then echo "Please specify a destination directory" exit 1 fi cd "${src_dir}" || exit 1 rm -rf "${dest_dir}" mkdir -p "${dest_dir}" IFS= find "./" \( -name '*.h' -o -name '*.hpp' -o -name '*.hxx' -o \ -name '*.c' -o -name '*.cc' -o \ -name '*.cpp' -o -name '*.cxx' -o -name '*.CC' -o \ -name '*.s' -o -name '*.S' \) -print | while read -r file do # This trims the leading "./" in "./foo.c". file=$(echo -n "${file}" | tr -s '/' | cut -c 3-); cp --parents --preserve=timestamps "${file}" "${dest_dir}" done exit 0 Jeff ^ permalink raw reply [flat|nested] 12+ messages in thread
