我试图在我通过
下载的Ubuntu 14.04 LTS上构建eglibc-2.19apt-get source libc6
我遵循了INSTALL指令,但在遇到nptl时遇到了这个错误

这是libpthread和nptl之间的某种冲突吗?如何解决这个问题? 提前谢谢。
答案 0 :(得分:1)
考虑到LinuxThreads已被NPTL取代,所以我只是从eglibc目录中删除了附加的libpthread,并重新进行了configure和make,然后现在一切似乎都没问题了。
请参阅LinuxThreads,NPTL
顺便说一句,因为我没有使用标准/ usr路径作为" - prefix =" configure的选项,所以我需要将libstdc ++。so.6和libgcc_s.so.1复制到我当前的构建路径以获取" make check"通过。答案 1 :(得分:1)
我得到了同样的错误,因为我运行了一个普通的./configure --prefix=/opt
,所以我改为运行apt-get source -b eglibc
,并注意到它使用的配置标志:
(exec 3>&1; exit `( ( ( cd build-tree/i386-libc && CC="i686-linux-gnu-gcc-4.8" CXX="i686-linux-gnu-g++-4.8" AUTOCONF=false MAKEINFO=: /home/sashoalm/Workspace/apt-get-source/libc/eglibc-2.19/configure --host=i686-linux-gnu --build=$configure_build --prefix=/usr --without-cvs --enable-add-ons=libidn,"nptl " --enable-profile --without-selinux --enable-stackguard-randomization --enable-obsolete-rpc --with-pkgversion="Ubuntu EGLIBC 2.19-0ubuntu6.9" --with-bugurl="https://bugs.launchpad.net/ubuntu/+source/eglibc/+bugs" --with-headers=/home/sashoalm/Workspace/apt-get-source/libc/eglibc-2.19/debian/include --enable-kernel=2.6.24 --with-selinux --enable-multi-arch ) 2>&1 3>&-; echo $? >&4) | tee -a build-tree/log-build-i686-linux-gnu-libc >&3) 4>&1`)
由于glibc坚持从一个单独的目录构建,因此命令相对复杂,比apt-get source
更复杂。实际的配置标志是:
--host=i686-linux-gnu --build=$configure_build --prefix=/usr --without-cvs --enable-add-ons=libidn,"nptl " --enable-profile --without-selinux --enable-stackguard-randomization --enable-obsolete-rpc --with-pkgversion="Ubuntu EGLIBC 2.19-0ubuntu6.9" --with-bugurl="https://bugs.launchpad.net/ubuntu/+source/eglibc/+bugs" --with-headers=/home/sashoalm/Workspace/apt-get-source/libc/eglibc-2.19/debian/include --enable-kernel=2.6.24 --with-selinux --enable-multi-arch
当然,它适用于那些参数,因为这是Ubuntu维护者用来编译包的原因。
我真的不知道哪些标志可以防止错误,但是如果你使用那个命令,或者你的Ubuntu系统上apt-get source -b eglibc
提供的确切参数,它应该可以运行得很好。
