我正在运行 openSUSE 11.4，它有点旧了，所以我正在尝试为我想要构建的另一个东西构建一些更新的依赖项。
我已经下载了源代码gcc-6.4.0（也尝试了最新的 - 没有用）。
我在跑../gcc-6.4.0/configure --prefix=/usr2/aakhavan/local --disable-multilib --enable-languages=c,c++ --disable-bootstrap --disable-libmpx --with-system-zlib
使用
gcc-build>gcc -v
Using built-in specs.
Target: x86_64-suse-linux
Configured with: ../configure --prefix=/usr --infodir=/usr/share/info --mandir=/usr/share/man --libdir=/usr/lib64 --libexecdir=/usr/lib64 --enable-languages=c,c++,objc,fortran,obj-c++,java,ada --enable-checking=release --with-gxx-include-dir=/usr/include/c++/4.3 --enable-ssp --disable-libssp --with-bugurl=http://bugs.opensuse.org/ --with-pkgversion='SUSE Linux' --disable-libgcj --disable-libmudflap --with-slibdir=/lib64 --with-system-zlib --enable-__cxa_atexit --enable-libstdcxx-allocator=new --disable-libstdcxx-pch --enable-version-specific-runtime-libs --program-suffix=-4.3 --enable-linux-futex --without-system-libunwind --with-cpu=generic --build=x86_64-suse-linux
Thread model: posix
gcc version 4.3.4 [gcc-4_3-branch revision 152973] (SUSE Linux)
失败的原因make如下：

我尝试禁用 libiberty，但它却抱怨构建 libtools。在网上搜索了一番，但找不到任何答案。到底发生了什么？
答案1
从编译中的错误 堆栈对象，很明显你没有正确的环境来构建gcc-6.4.0。
我注意到可以通过以下命令安装 gcc：
sudo zypper install gcc
你可以找到包 gcc6-6.5.0+r265524-2.1.x86_64.rpm 在存储库中 下载.opensuse.org/repositories/devel:/gcc/SLE-11/x86_64/，无需编译任何东西。
事实上，复制旧软件包最初编译时的确切环境是极其困难的。找到它的发布版本要容易得多，也省时得多。因为 glibc 确实 向下兼容，即使您环境中的 glibc 较新，这也会起作用，因此即使您无法再编译该程序，因为您的头文件不是正确的版本。
