glibc編譯不正確

Question

在編譯glibc 2.11時，出現以下錯誤。任何想法如何解決這個問題。

In file included from ../sysdeps/unix/sysv/linux/syslog.c:10: 
../misc/syslog.c: In function ‘__vsyslog_chk’: 
../misc/syslog.c:123: sorry, unimplemented: inlining failed in call to ‘syslog’: function body not available 
../misc/syslog.c:155: sorry, unimplemented: called from here

顯然，這是一個known problem with building glibc on Ubuntu。本質上：

glibc does not build with _FORTIFY_SOURCE enabled，和Ubuntu編譯-D_FORTIFY_SOURCE=2的東西。

您需要通過取消定義_FORTIFY_SOURCE來禁用此功能。即附加-U_FORTIFY_SOURCE到您的CFLAGS。
