From 4578e116182c3bc972b770a9cbdf69749dc234f9 Mon Sep 17 00:00:00 2001 From: Nirbheek Chauhan Date: Tue, 24 May 2016 12:17:40 +0530 Subject: compilers: Always include limits.h to make the stub machinery work limits.h is a requirement of the C language and is available with all compilers and platforms from the last two decades. If limits.h is not available, the compiler only supports an ancient dialect of C and lots of other things will break too. --- mesonbuild/compilers.py | 3 +++ 1 file changed, 3 insertions(+) diff --git a/mesonbuild/compilers.py b/mesonbuild/compilers.py index 492b790..494b6c6 100644 --- a/mesonbuild/compilers.py +++ b/mesonbuild/compilers.py @@ -692,6 +692,7 @@ int main(int argc, char **argv) { # Then, undef the symbol to get rid of it completely. templ = ''' #define {1} meson_disable_define_of_{1} + #include {0} #undef {1} ''' @@ -709,6 +710,8 @@ int main(int argc, char **argv) { # glibc defines functions that are not available on Linux as stubs that # fail with ENOSYS (such as e.g. lchmod).
