From 805e3ce0c20bee5049ff167ab6f620a230c6db51 Mon Sep 17 00:00:00 2001 From: Khem Raj Date: Wed, 15 Apr 2020 14:17:20 -0700 Subject: [PATCH] Check for clang before checking gcc version Clang advertises itself to be gcc 4.2.1, so when compiling this test here fails since gcc < 4.4.5 did not support -static-libstdc++ but thats not true for clang, so its better to make an additional check for clang before resorting to gcc version check. This should let clang enable static libstdc++ linking Upstream-Status: Pending Signed-off-by: Khem Raj --- configure | 2 +- configure.ac | 2 +- 2 files changed, 2 insertions(+), 2 deletions(-) diff --git a/configure b/configure index 7b369071141..7da69e27ce9 100755 --- a/configure +++ b/configure @@ -5093,7 +5093,7 @@ ac_compiler_gnu=$ac_cv_cxx_compiler_gnu cat confdefs.h - <<_ACEOF >conftest.$ac_ext /* end confdefs.h. */ -#if (__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5) +#if !defined(__clang__) && ((__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5)) #error -static-libstdc++ not implemented #endif int main() {} diff --git a/configure.ac b/configure.ac index 92f01fb3ed7..e99d67ab86b 100644 --- a/configure.ac +++ b/configure.ac @@ -1311,7 +1311,7 @@ if test "$GCC" = yes; then AC_MSG_CHECKING([whether g++ accepts -static-libstdc++ -static-libgcc]) AC_LANG_PUSH(C++) AC_LINK_IFELSE([AC_LANG_SOURCE([ -#if (__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5) +#if !defined(__clang__) && ((__GNUC__ < 4) || (__GNUC__ == 4 && __GNUC_MINOR__ < 5)) #error -static-libstdc++ not implemented #endif int main() {}])],
