我正在从 CentOS 源代码构建 2.6.18。
我正按照他们的说明进行构建过程的最后一步，但似乎出现了我无法理解的错误。
我遵循的说明： http://wiki.centos.org/HowTos/Custom_Kernel
我运行了... [user@host SPECS]$ rpmbuild -bb --target= uname -mkernel.spec 2> build-err.log | tee build-out.log
并得到……

RPM build errors:
我不知道为什么“RPM 构建错误”后没有有用的消息。运行上述 rpmbuild 命令后，我应该看到在 ~/rpmbuild/RPMS/ uname -m/ 目录中生成的“自定义内核 rpm 文件”。但我在该文件夹中没有看到任何内容。
以下是我在 build-err.log 中看到的内容：

答案1
看起来您正在尝试在 32 位平台（或仅具有 32 位开发工具链的平台）上交叉编译 64 位内核。您安装的工具链（或如果您有多个，则您选择的工具链）不支持 64 位目标。
