building gcc - fatal error: libgcc_tm.h: No such file or directory

Question

我正在建设

gcc

$ git status
HEAD detached at releases/gcc-12.2.0

当前版本的 gcc, g++:

 /cygdrive/c/work/misc/gcc-trunk
$ gcc --version
gcc (GCC) 11.3.0

命令：

./configure --enable-languages=c,c++
make -j8

我得到的错误是：

../.././libgcc/libgcc2.c:30:10: 致命错误：libgcc_tm.h: 没有这样的文件 或目录 30 | #include "libgcc_tm.h" | ^~~~~~~~~~~~~ 编译终止。 make[3]: *** [Makefile:501: _muldi3.o] 错误 1

问题：
应该生成这个文件还是我缺少一个库？
