From 25c045763a08a579feb6e42f9361edd1ca6333ae Mon Sep 17 00:00:00 2001 From: Ryan Mounce Date: Thu, 3 Aug 2017 20:37:58 +0930 Subject: tools: patch various gnu tools for macOS 10.13 These host tools compile but may crash at runtime when building on macOS 10.13 (High Sierra). Backport upstream gnulib patch until new releases of affected tools. https://lists.gnu.org/archive/html/bug-gnulib/2017-07/msg00056.html https://git.savannah.gnu.org/cgit/gnulib.git/commit/?id=c41f233c4c38e84023a16339782ee306f03e7f59 Signed-off-by: Ryan Mounce --- tools/bison/patches/001-fix-macos-vasnprintf.patch | 25 ++++++++++++++++++++++ 1 file changed, 25 insertions(+) create mode 100644 tools/bison/patches/001-fix-macos-vasnprintf.patch (limited to 'tools/bison/patches') diff --git a/tools/bison/patches/001-fix-macos-vasnprintf.patch b/tools/bison/patches/001-fix-macos-vasnprintf.patch new file mode 100644 index 0000000000..e41315d34e --- /dev/null +++ b/tools/bison/patches/001-fix-macos-vasnprintf.patch @@ -0,0 +1,25 @@ +--- a/lib/vasnprintf.c ++++ b/lib/vasnprintf.c +@@ -4858,7 +4858,11 @@ VASNPRINTF (DCHAR_T *resultbuf, size_t * + #endif + *fbp = dp->conversion; + #if USE_SNPRINTF +-# if !(((__GLIBC__ > 2 || (__GLIBC__ == 2 && __GLIBC_MINOR__ >= 3)) && !defined __UCLIBC__) || ((defined _WIN32 || defined __WIN32__) && ! defined __CYGWIN__)) ++# if !
