在Ubuntu16.04交叉编译x86_64-w64-mingw32版GCC6.3.0报错求助

问题背景 #

在Ubuntu 16.04系统中为x86_64-w64-mingw32目标交叉编译GCC 6.3.0，执行以下步骤后编译报错：

执行步骤 #

• 0. 获取源码文件

  wget "http://sourceforge.net/projects/mingw-w64/files/mingw-w64/mingw-w64-release/mingw-w64-v5.0.1.tar.bz2"
  wget  "https://ftpmirror.gnu.org/binutils/binutils-2.27.tar.gz"
  wget "https://ftpmirror.gnu.org/gcc/gcc-6.3.0/gcc-6.3.0.tar.bz2"
  

• 1. 编译binutils-2.27

  ./configure --target=x86_64-w64-mingw32 --enable-targets=x86_64-w64-mingw32 --prefix=/home/user/gcc_mingw64/build --with-sysroot=/home/user/gcc_mingw64/build
  make
  make install
  

• 2. 编译mingw-w64-v5头文件

  mkdir build-headers
  cd build-headers/
  ../mingw-w64-headers/configure --host=x86_64-w64-mingw32 --prefix=/home/user/gcc_mingw64/build/x86_64-w64-mingw32
  make
  make install
  

• 3. 创建库软链接

  ln -s /home/user/gcc_mingw64/build/x86_64-w64-mingw32 mingw
  ln -s /home/user/gcc_mingw64/build/x86_64-w64-mingw32/lib lib64
  

• 4. 编译gcc-6.3.0

  ./contrib/download_prerequisites
  mkdir build_gcc
  cd build_gcc
  ../configure --target=x86_64-w64-mingw32 --enable-targets=all --disable-werror --disable-shared --enable-version-specific-runtime-libs --with-ld=/home/user/gcc_mingw64/build/bin/x86_64-w64-mingw32-ld --with-as=/home/user/gcc_mingw64/build/bin/x86_64-w64-mingw32-as --enable-languages=c,c++,fortran --prefix=/home/user/gcc_mingw64/build --with-sysroot=/home/user/gcc_mingw64/build
  make
  make install
  

错误信息 #

checking for ld that supports -Wl,--gc-sections... configure: error: Link tests are not allowed after GCC_NO_EXECUTABLES.
Makefile:11457: recipe for target 'configure-target-libstdc++-v3' failed
make[1]: *** [configure-target-libstdc++-v3] Error 1

解决思路 #

1. 调整GCC配置参数 #

• 移除--disable-shared参数：交叉编译场景下禁用共享库会破坏libstdc++-v3的配置逻辑，导致链接测试触发限制。修改后的configure命令：

  ../configure --target=x86_64-w64-mingw32 --enable-targets=all --disable-werror --enable-version-specific-runtime-libs --with-ld=/home/user/gcc_mingw64/build/bin/x86_64-w64-mingw32-ld --with-as=/home/user/gcc_mingw64/build/bin/x86_64-w64-mingw32-as --enable-languages=c,c++,fortran --prefix=/home/user/gcc_mingw64/build --with-sysroot=/home/user/gcc_mingw64/build
  

• 若问题未解决，追加--disable-libstdcxx-pch参数，跳过预编译头的生成逻辑，避免触发链接测试。

2. 验证sysroot与链接路径 #

• 检查软链接有效性：

  ls -l /home/user/gcc_mingw64/build/mingw
  ls -l /home/user/gcc_mingw64/build/lib64
  

  确认链接指向的x86_64-w64-mingw32目录存在且内容完整。
• 检查sysroot下的头文件与基础库：确认/home/user/gcc_mingw64/build/x86_64-w64-mingw32/include和lib目录包含完整的mingw-w64头文件与库文件。

3. 补全mingw-w64库编译 #

之前仅编译了mingw-w64的头文件，缺少crt库会导致GCC编译libstdc++时依赖不足。回到mingw-w64源码目录，执行以下步骤编译crt库：

mkdir build-crt
cd build-crt
../configure --host=x86_64-w64-mingw32 --prefix=/home/user/gcc_mingw64/build/x86_64-w64-mingw32
make
make install

4. 清理缓存后重新构建 #

删除GCC的编译目录，重新执行配置与编译：

rm -rf build_gcc
mkdir build_gcc
cd build_gcc
# 执行修改后的configure命令
make
