Help : CLFS紧急求助

晨想

如果包版本一样的话，就不会有什么问题。你才开始，建议重新开始一次，看看问题是否还存在。不过记得要把目录删除干净！

昨天晚上重新更新了文件，今天准备继续搞：）

我重新下载了所有新的包，重新编译，宿主环境是gentoo，这回真的确认不支持nptl了，结果到了5.8. Glibc-20051107的Prepare Glibc for compilation: 时，configure又不过，报错如下：

configure: error: forced unwind support is required


难道非宿主系统非得要有nptl支持，才能编译cross tools吗？ 又一次受打击了，不过我一定要继续搞下去。哪位大侠支支手啊....... sos

晨想

running configure fragment for add-on nptl

你编译的 glibc 是用nptl的。CVS的 glibc 默认就带 nptl。你删除了 nptl 这个目录再 configure 试试。

我想可能是对原文意思理解有误吧， file:///E:/Tmp/LFS-BOOK-CLFS-SVN-20060214-HTML/x86/cross-tools/glibc.html 里面说成这样：
For NPTL enabled systems the following lines need to be added to config.cache:
echo "libc_cv_forced_unwind=yes" > config.cache
echo "libc_cv_c_cleanup=yes" >> config.cache

我就觉得这里的systems是指host，而我的gentoo是不支持nptl的，但后面编译Glibc，在configure时，说forced unwind support is required。我实在没办法，只好把上面 echo 又加进去重编译，没想到居然过了。所以我觉得上面那句话意思应该是：如果你想让编译的glibc支持nptl，就要把那两个echo加到config.cache中。

晨想

你理解的没错。（至少我觉得你没错）。

至于 “在configure时，说forced unwind support is required ” 这个问题，你试试删除 glibc-xxx 目录下边的 nptl 目录再configure。
