您好，我想请问一下，使用编译gcc的时候，出现configure: error: cannot compute suffix of object files: cannot compile，这个问题有什么解决方案嘛》？

您好，我想请问一下，使用编译gcc的时候，出现configure: error: cannot compute suffix of object files: cannot compile，这个问题有什么解决方案嘛》？

应该是在 configure 阶段，编译测试时没有成功造成的，具体可以看一下 config.log 文件，看看里面报了什么错。

您好，我使用的是 https://github.com/loongson/gcc项目中的源码，在编译的过程中，编译到libgcc模块的时候报了如下错误:

关于configure的调用如下所示:
../configure --enable-bootstrap --enable-languages=c,c++,fortran,objc,obj-c++,lto --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=https://bugs.openanolis.cn --enable-shared --enable-threads=posix --enable-checking=release --enable-multilib --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-gnu-unique-object --enable-linker-build-id --with-gcc-major-version-only --with-linker-hash-style=gnu --enable-plugin --enable-initfini-array --with-isl --disable-libmpx --build=loongarch64-loongson-linux

关于make如下所示:
make -j32 'BOOT_CFLAGS=-O2 -g' BOOT_LDFLAGS= LDFLAGS_FOR_TARGET= profiledbootstrap

我研究了该config.log已经两三天了，实在没有发现存在什么问题，如有了解请指点一二~

[yetist]

问题是这个:

Error: unrecognized option -'lp64d

背景情况我不确定，从 config.log 中我推断，你应该是在产品版系统中，编译社区版gcc代码，是吗？

如果是这样的话，请阅读最新的龙芯架构工具链约定文档，这个选项在产品版本中是没有支持的。
