编译GCC-13源码触发删除构造函数错误，求配置及解决建议

问题场景 #

在编译GCC源码的releases/gcc-13分支时，执行make命令触发编译错误，具体信息如下。

错误日志 #

当前使用的编译工具链 #

clang -version
clang version 4.0.0-1kord1 (tags/RELEASE_400/rc1)
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin

编译配置参数 #

./configure \
--host=aarch64-linux-gnu \
--enable-languages=c,c++,fortran,go \
--prefix=/home/.gccb/gcc-13 \
--enable-targets=aarch64-linux-gnu \
--with-gmp=/usr/local \
--with-mpfr=/usr/local \
--with-mpc=/usr/local

解决方向 #

• 升级Clang版本：Clang 4.0.0是2017年的老旧版本，对现代C特性支持不足。GCC 13源码依赖较新的C标准，旧编译器无法正确处理obstack_watermark的禁用拷贝逻辑。建议升级到Clang 12+版本，或直接用系统自带的GCC编译GCC（更稳妥）。
• 校验源码完整性：重新拉取releases/gcc-13分支代码，执行git fetch --tags && git checkout releases/gcc-13，确保无文件缺失或损坏。
• 调整配置参数：
  • 删除--enable-targets=aarch64-linux-gnu，--host已指定目标架构，重复设置易引发冲突。
  • 检查GMP、MPFR、MPC版本：GCC 13要求GMP≥6.2.1、MPFR≥4.1.0、MPC≥1.2.1，版本过低则升级对应依赖库。
• 切换编译工具链：若系统有GCC 7+版本，执行CC=gcc CXX=g++ ./configure [你的其他参数]重新配置，用GCC编译GCC可避免兼容性问题。
