From fcf24b9f388d650a92375079461198f5db3ed88a Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Mat=C3=BA=C5=A1=20Olek=C5=A1=C3=A1k?= Date: Wed, 21 Feb 2018 12:03:04 -0500 Subject: fix detection of LIBCC for compiler-rt with clang Maintainer's note: at one point, -lcompiler_rt apparently worked, and may still work and be preferable if one has manually installed the library in a public lib directory. but with current versions of clang, the full pathname to the library file is needed. the original patch removed the -lcompiler_rt check; I have left it in place in case there are users depending on it, and since, when it does work, it's preferable so as not to code a dependency on the specific compiler version and paths in config.mak. --- configure | 2 ++ 1 file changed, 2 insertions(+) (limited to 'configure') diff --git a/configure b/configure index 501a7219..1e59c461 100755 --- a/configure +++ b/configure @@ -598,6 +598,8 @@ tryldflag LDFLAGS_AUTO -Wl,-Bsymbolic-functions # Find compiler runtime library test -z "$LIBCC" && tryldflag LIBCC -lgcc && tryldflag LIBCC -lgcc_eh test -z "$LIBCC" && tryldflag LIBCC -lcompiler_rt +test -z "$LIBCC" && try_libcc=`$CC -print-libgcc-file-name 2>/dev/null` \ + && tryldflag LIBCC "$try_libcc" test -z "$LIBCC" && try_libcc=`$CC -print-file-name=libpcc.a 2>/dev/null` \ && tryldflag LIBCC "$try_libcc" printf "using compiler runtime libraries: %s\n" "$LIBCC" -- cgit v1.2.1
