Question

我正在关注http://www.openrisc.net/toolchain-build.html以了解如何设置交叉编译器工具链。并且已经重建uClibc并发现库文件未正确安装在$ {SYSROOT} / usr / lib中。（只有5出无论如何都要复制8个文件）所以我试图从头开始做，现在我被困在为第一遍传递编译gcc ..

我以前安装了gmp，mpfr和mpc。它们安装在/ usr / local下。（标头位于/ usr / local / include中，库位于/ usr / local / lib中）所以对于gcc编译，我运行（在gcc-build目录下）

../ gcc-svn / configure --target = or32-linux --prefix = $ PREFIX --disable-libssp --srcdir = .. / gcc-svn --enable-languages = c - without-headers --enable-threads = single --disable-libgomp --disable-libmudflap --with-gmp = / usr / local --with-mpfr = / usr / local --with-MPC =的/ usr /本地

然后跑

请

它给了我这个错误信息（显示错误部分）检查目标文件的后缀... configure：error：in /home/ckim/openrisc/toolchain/gcc-build/or32-linux/libgcc': configure: error: cannot compute suffix of object files: cannot compile See config.log'以获取更多详细信息。 make [1]： * [configure-target-libgcc]错误1 make [1]：离开目录`/ home / ckim / openrisc / toolchain / gcc-build' make：* [all]错误2

所以我查看了/home/ckim/openrisc/toolchain/or32-linux/libgcc/config.log文件。错误的部分显示了这一点。（完整日志文件位于http://pastebin.com/6HdfrqBy）

搜索消息显示它可能与没有gmp，mfpr，mpc库有关。这是Cento6.4。在源外构建，LD_LIBRARY_PATH和LIBRARY_PATH有/ usr / local / lib（对于gmp，mpfr和 MPC）。尝试添加--program-prefix = or32-linux，删除所有文件后尝试.. 任何人都可以对此有所了解吗？

Answer 1

您是否尝试使用包含的依赖脚本将所需的库引入gcc构建环境？

contrib/download_prerequisites

这样做比在外部构建库并尝试将gcc配置指向它们更容易，更容易出错。

编译gcc，configure：error：无法计算目标文件的后缀：无法编译
