From 91307a366625e3ec7e618f012269130d2e5bba57 Mon Sep 17 00:00:00 2001 From: Eric Andersen Date: Fri, 4 May 2001 22:29:43 +0000 Subject: This patch allows powerpc to compile again. It also checks if we are compiling for an arch for which uClibc has an ld.so or not, and otherwise sets things up to use the system ld.so. -Erik --- libc/sysdeps/linux/common/statfix.h | 2 + libc/sysdeps/linux/powerpc/bits/errno.h | 60 +++++++++++++++++++++++ libc/sysdeps/linux/powerpc/bits/sem.h | 87 +++++++++++++++++++++++++++++++++ 3 files changed, 149 insertions(+) create mode 100644 libc/sysdeps/linux/powerpc/bits/errno.h create mode 100644 libc/sysdeps/linux/powerpc/bits/sem.h (limited to 'libc') diff --git a/libc/sysdeps/linux/common/statfix.h b/libc/sysdeps/linux/common/statfix.h index 6dad72dc4..eaf623b0e 100644 --- a/libc/sysdeps/linux/common/statfix.h +++ b/libc/sysdeps/linux/common/statfix.h @@ -1,6 +1,8 @@ #ifndef STATFIX_H #define STATFIX_H +#include + /* Pull in whatever this particular arch's kernel thinks the kernel version of * struct stat should look like.
