Share gcc work directories
This patched is derived from Richard, make gcc use the shared source directory during the different building: 1) Make gcc-cross, gcc-cross-initial, gcc-cross-intermediate and gcc-runtime share the same source directory. 2) The source directory is ${TMPDIR}/work-shared/gcc-${PV}, for example: tmp/work-shared/gcc-4.5.1 3) Fix do_clean to clean the shared source directory and stamps 4) gcc uses sed and creates config files against ${S} which means the directory should not be shared. Change the way to make it work: * The configure option --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} can replace the sed command, see the code in configure: if test "x$with_headers" != x; then glibc_header_dir=$with_headers This has the same effect as the sed command: sed -i 's:^\([ ]*\)glibc_header_dir=\"${with_build_sysroot}/usr/include\": ... so add the --with-headers=${STAGING_DIR_TARGET}${SYSTEMHEADERS} to gcc-configure-cross.inc( not add to gcc-configure-common.inc, since not all the gcc building need this, the one which has its own do_configure doesn't need it). * Move t-oe from ${T} to ${B}/gcc, so that the patched Makefile.in can read it easily, please see the commit for gcc-4.5.1 and gcc-4.6.0. * Use the defaults.h in ${B}/gcc instead of ${S}/gcc, and the patched configure.ac(configure) can read it correctly, please see the commit for gcc-4.5.1 and gcc-4.6.0. * The gcc-crosssdk.inc used sed to edit ${S}/config/*/linux*.h to change the GLIBC_DYNAMIC_LINKER, which made the source incompatible. To make the source compatible: - Use: sed -i ${S}/gcc/config/*/linux*.h -e \ 's#\(GLIBC_DYNAMIC_LINKER[^ ]*\)\( *"/lib.*\)#\1 SYSTEMLIBS_DIR\2#' so entries in the files that look like: #define GLIBC_DYNAMIC_LINKER64 "/lib64/ld-linux-x86-64.so.2" would become #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2" and we define SYSTEMLIBS_DIR in defaults.h. NOTE: #define GLIBC_DYNAMIC_LINKER64 (SYSTEMLIBS_DIR "/ld-linux-x86-64.so.2") doesn't work in in the following define: #define LINUX_DYNAMIC_LINKER \ CHOOSE_DYNAMIC_LINKER (GLIBC_DYNAMIC_LINKER, UCLIBC_DYNAMIC_LINKER) so use #define GLIBC_DYNAMIC_LINKER64 SYSTEMLIBS_DIR"/ld-linux-x86-64.so.2" 5) Add do_configure_prepend to gcc-configure-common.inc and remove the one in gcc-crosssdk.inc, this makes it easy to share the source, otherwise we need do extra changes in gcc-configure-sdk.inc. 6) Use "cat > file <_EOF" to replace the "echo > file" (From OE-Core rev: 934d38530c9a67562e53d4034aee5531f0f26750) Signed-off-by: Robert Yang <liezhi.yang@windriver.com> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
