大厦libgc无法在Mac OS X 10.6雪豹：...并要求_XOPEN_SOURCE来定义

Question

以下步骤：

$ wget http://www.hpl.hp.com/personal/Hans_Boehm/gc/gc_source/gc-7.0.tar.gz 
$ tar xvfz gc-7.0.tar.gz 
$ cd gc-7.0 
$ ./configure 
$ make 

失败，此错误：

In file included from mach_dep.c:163: 
/usr/include/ucontext.h:42:2: error: #error ucontext routines are deprecated, 
and require _XOPEN_SOURCE to be defined 

Answer 1

ucontext.h包括在这里：

$ fstr "ucontext.h" # find string ... 
./mach_dep.c:163 
./os_dep.c:2752 

在mach_dep.c与更换。
