From 18e95320986243696f31f4b596761eb35759dfe9 Mon Sep 17 00:00:00 2001 From: Alec Mocatta Date: Tue, 10 Apr 2018 18:44:47 +0100 Subject: [PATCH] Add --enable-debug flag to musl CI build script MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Building for x86_64-unknown-linux-musl currently results in an executable lacking debug information for musl libc itself. If you request a backtrace in GDB while control flow is within musl – including sycalls made by musl – the result looks like: #0 0x0000000000434b46 in __cp_end () #1 0x0000000000432dbd in __syscall_cp_c () #2 0x0000000000000000 in ?? () i.e. not very helpful. Adding --enable-debug resolves this, and --enable-optimize re-enables optimisations which default to off given the previous flag. --- src/ci/docker/scripts/musl.sh | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/src/ci/docker/scripts/musl.sh b/src/ci/docker/scripts/musl.sh index fb0bd06ce3099..f87ba8fe4e60e 100644 --- a/src/ci/docker/scripts/musl.sh +++ b/src/ci/docker/scripts/musl.sh @@ -40,7 +40,7 @@ if [ ! -d $MUSL ]; then fi cd $MUSL -./configure --disable-shared --prefix=/musl-$TAG $@ +./configure --enable-optimize --enable-debug --disable-shared --prefix=/musl-$TAG $@ if [ "$TAG" = "i586" -o "$TAG" = "i686" ]; then hide_output make -j$(nproc) AR=ar RANLIB=ranlib else
