交叉围栏GCC:在检查动态链接器特征时，在GCC_NO_EXECUTABLES之后不允许链接测试

Crosscompiling GCC: Link tests are not allowed after GCC_NO_EXECUTABLES when checking dynamic linker characteristics

本文关键字：GCC 链接 NO EXECUTABLES 之后 测试 不允许 特征 检查 动态      更新时间：2023-10-16

我正在尝试通过此操作来编译LFS的gcc-4.8.3。

使用make时，我会收到以下错误：

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

    --disable-libstdcxx                            
    --enable-languages=c,c++

其中 $LFS_TGT是 x86_64-lfs-linux-gnu。

pastebin上的 config.log。

如果您在x86_64机器上构建了此功能，并且将x86_64作为目标，则实际上并没有构建交叉编译器。
您似乎正在构建隔离的stage1编译器，因此您必须添加--disable-bootstrap标志。GCC默认情况下，如果您的构建目标平台不是本机平台（交叉编译器）。

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（目标x86_64-lfs-linux-gnu），需要安装。

hth。

如果要构建LFS，则应检查使用的用户，并确保它不是根。

您需要检查config.log以找出命令configure尝试运行的命令；例如：

configure:9604: checking whether the x86_64-lfs-linux-gnu-gcc linker (/usr/x86_64-lfs-linux-gnu/bin/ld -m elf_x86_64
) supports shared libraries
configure:10684: result: no
configure:10929: checking dynamic linker characteristics
configure:11375: error: Link tests are not allowed after GCC_NO_EXECUTABLES.

在这种情况下，手动运行/usr/x86_64-lfs-linux-gnu/bin/ld -m elf_x86_64。它可能会产生类似的东西：

/usr/x86_64-lfs-linux-gnu/bin/ld: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory

因此，在这种情况下，您会知道找不到libz.so.1。
