When we run in +an environment where /tmp has rarely been used, the newly created temporary file +may have a very low inode number. If the inode number was 6 which is the same as +/dev/null, gcc would wrongly think the input file and the output file are the +same and report the following error. + +*** Compiler lacks asm-goto support.. Stop. + +The fix below for the bug has not been released from upstream. Since there has +not been gcc-cross when building linux-libc-headers, we have to use build +machine gcc which could not contain the fix for the moment. To work around the +error, we create a fixed temporary file to contain the program being tested. + +https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=commit;h= +2a50366ded329bfb39d387253450c9d5302c3503 + +This patch also removes ">/dev/null 2>&1" so we will have more direct error +information in case something else wrong happened. + +Upstream-Status: Inappropriate [Just a work around for old gcc] + +Signed-off-by: He Zhe <zhe...@windriver.com> +--- + scripts/gcc-goto.sh | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +diff --git a/scripts/gcc-goto.sh b/scripts/gcc-goto.sh +index 083c526..0aaf1b4 100755 +--- a/scripts/gcc-goto.sh ++++ b/scripts/gcc-goto.sh +@@ -3,7 +3,9 @@ + # Test for gcc 'asm goto' support + # Copyright (C) 2010, Jason Baron <jba...@redhat.com> + +-cat << "END" | $@ -x c - -c -o /dev/null >/dev/null 2>&1 && echo "y" ++TMPFILE=`mktemp -p .` ++ ++cat << "END" > ${TMPFILE} + int main(void) + { + #if defined(__arm__) || defined(__aarch64__) +@@ -20,3 +22,6 @@ entry: + return 0; + } + END ++ ++$@ -x c ${TMPFILE} -c -o /dev/null && echo "y" ++rm ${TMPFILE} +-- +2.7.4 + diff --git a/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_4.18.bb b/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_4.18.bb index eb7bee7..00420aa 100644 --- a/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_4.18.bb +++ b/meta/recipes-kernel/linux-libc-headers/linux-libc-headers_4.18.bb @@ -9,5 +9,9 @@ SRC_URI_append_libc-musl = "\ file://0001-include-linux-stddef.h-in-swab.h-uapi-header.patch \ " +SRC_URI_append = "\ + file://0001-scripts-Use-fixed-temporary-file-instead-of-pipe-for.patch \ +" + SRC_URI[md5sum] = "bee5fe53ee1c3142b8f0c12c0d3348f9" SRC_URI[sha256sum] = "19d8bcf49ef530cd4e364a45b4a22fa70714b70349c8100e7308488e26f1eaf1" -- 2.7.4 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
