Linux 使用llvm/clang构建gdb

我正试图从源代码构建gdb。我正在使用“GDB7.6标签”

我得到以下错误：

opncls.c:263:5: error: expression result unused [-Werror,-Wunused-value]
    bfd_set_cacheable (nbfd, TRUE);
    ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
./bfd.h:529:67: note: expanded from:
#define bfd_set_cacheable(abfd,bool) (((abfd)->cacheable = bool), TRUE)
                                                                  ^
./bfd.h:134:14: note: expanded from:
#define TRUE 1

---

停止将警告视为错误。[删除

-Werror

]。这解决了我的问题：
