Remove "--disable-openmp" from the GCC configuration options and always build libgomp. This only creates a "bigger" compiler but has no effect on the compiled binaries that don't use openmp. Tested a clean build on mips32el and arm7a, no problems encountered. Autoconf will not detect OpenMP after this change, because it will build and run a target binary on the build system. In order to use OpenMP, the variable ac_cv_prog_c_openmp=-fopenmp must be set. --- meta/recipes-devtools/gcc/gcc-4.7.inc | 1 - .../recipes-devtools/gcc/gcc-configure-runtime.inc | 4 +--- 2 files changed, 1 insertions(+), 4 deletions(-) diff --git a/meta/recipes-devtools/gcc/gcc-4.7.inc b/meta/recipes-devtools/gcc/gcc-4.7.inc index 08a0103..2548f84 100644 --- a/meta/recipes-devtools/gcc/gcc-4.7.inc +++ b/meta/recipes-devtools/gcc/gcc-4.7.inc @@ -88,7 +88,6 @@ JAVA = "" EXTRA_OECONF_BASE = " --enable-lto \ --enable-libssp \ --disable-bootstrap \ - --disable-libgomp \ --disable-libmudflap \ --with-system-zlib \ --with-linker-hash-style=${LINKER_HASH_STYLE} \ diff --git a/meta/recipes-devtools/gcc/gcc-configure-runtime.inc b/meta/recipes-devtools/gcc/gcc-configure-runtime.inc index d40383c..1c9155f 100644 --- a/meta/recipes-devtools/gcc/gcc-configure-runtime.inc +++ b/meta/recipes-devtools/gcc/gcc-configure-runtime.inc @@ -7,9 +7,7 @@ EXTRA_OECONF_PATHS = " \ --with-sysroot=${STAGING_DIR_TARGET} \ --with-build-sysroot=${STAGING_DIR_TARGET}" -RUNTIMETARGET = "libssp libstdc++-v3" -RUNTIMETARGET_append_powerpc = " libgomp" -RUNTIMETARGET_append_powerpc64 = " libgomp" +RUNTIMETARGET = "libssp libstdc++-v3 libgomp" # ? # libiberty # libmudflap
