交叉编译 GCC：检查动态链接器特性时，不允许在 GCC_NO_EXECUTABLES 之后进行链接测试

Question

我正在尝试gcc-4.8.3按照这个为 LFS编译。

使用时make，出现以下错误：

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++

哪里$LFS_TGT是x86_64-lfs-linux-gnu。

config.log在PasteBin 上。

最后几行输出：

Answer 1

如果您在x86_64机器上构建它并且您将其x86_64作为目标，那么您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

如果您正在构建 LFS，您应该检查您正在使用的用户并确保它不是 root。
