安裝步驟
- 在 make.config 的 USE flag 加入 nptl nptlonly
如下:
USE="apache2 nptl nptlonly nls zh_TW -java -toys threads"
- 修改 linux-header 從 2.4 到 2.6 (在 2004.3 的 Gentoo 似乎己經升級到 2.6 了)
#emerge -C linux-headers 移掉 linux-headers #emerge --oneshot linux26-headers #emerge glibc 重新 Compile glibc
確認 NPTL 有加入到 glibc 內，有"Native POSIX Threads Library by Ulrich Drepper et al"那一行才表示有正確裝到 NPTL.

或是使用
#getconf GNU_LIBPTHREAD_VERSION NPTL 2.3.4
檢查NPTL 版本
Gentoo 若是只有加上 nptl flag ，會 compile 二次一次 for Linux Thread，另一次是 nptl ，文件內說到預設是用 nptl，不過我自己試的結果是用 nptlonly 比較穩當
glibc 沒有支援 nptl 的時候會顯示 "linuxthreads-0.10 by Xavier Leroy"

Gentoo 內支援 NPTL 的 Portage

我是用 GENTOO-PORTAGE 查的.

問題
在安裝 NPTL 的時候，遇到了一些問題 首先是，要處理 linux-headers Package 的問題，解決如下.
狀況如下
# emerge -p glibc These are the packages that I would merge, in order: Calculating dependencies ...done! [blocks B ] sys-kernel/linux-headers (from pkg sys-kernel/linux26-headers-2.6.8.1-r1) [ebuild N ] sys-kernel/linux-headers-2.4.22 [ebuild N ] sys-kernel/linux26-headers-2.6.8.1-r1 [ebuild U ] sys-libs/glibc-2.3.4.20041102 [2.3.4.20041006]
解法
# emerge -C linux-headers # emerge --oneshot linux26-headers # emerge libc
