交叉编译GCC：在检查动态链接器特性时，GCC_NO_EXECUTABLES后不允许链接测试

Question

我正在尝试通过跟随gcc-4.8.3为LFS编译this。

使用make时，我收到以下错误：

checking dynamic linker characteristics... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
make[1]: *** [configure-target-libstdc++-v3] Error 1
make[1]: Leaving directory `/mnt/c/Users/admin/Desktop/Projects/AssaultArchitecture/sources/gcc-4.8.3/build'
make: *** [all] Error 2

配置选项：

../configure                                       \
    --target=$LFS_TGT                              \
    --prefix=/tools                                \
    --with-glibc-version=2.11                      \
    --with-sysroot=$LFS                            \
    --with-newlib                                  \
    --without-headers                              \
    --with-local-prefix=/tools                     \
    --with-native-system-header-dir=/tools/include \
    --disable-nls                                  \
    --disable-shared                               \
    --disable-multilib                             \
    --disable-decimal-float                        \
    --disable-threads                              \
    --disable-libatomic                            \
    --disable-libgomp                              \
    --disable-libmpx                               \
    --disable-libquadmath                          \
    --disable-libssp                               \
    --disable-libvtv                               \
    --disable-libstdcxx                            \
    --enable-languages=c,c++

其中$LFS_TGT是x86_64-lfs-linux-gnu。

config.log在PasteBin。

最后几行输出：

Answer 1

如果你在x86_64机器上构建它并且你有x86_64作为目标，那么你实际上并没有构建交叉编译器。 您似乎正在构建一个独立的stage1编译器，因此您必须添加--disable-bootstrap标志。如果您的构建目标平台不是本机平台（交叉编译器），则GCC默认禁用引导程序。

Answer 2

这里涉及完全相同的问题：

https://gcc.gnu.org/ml/gcc-help/2012-07/msg00018.html

建议可能缺少适当的glibc（针对x86_64-lfs-linux-gnu），需要安装。

HTH。
