OS X编译bochs报错 [configure: error: C compiler cannot create executables]

Question

根据这个链接做安装前的配置

sh .conf.macosx后出现以下信息
根据google到的信息，缺少command line tools，已经执行xcode-select --install并完成安装。

gcc版本不对？ 缺乏库？

checking build system type... x86_64-apple-darwin13.1.0
checking host system type... x86_64-apple-darwin13.1.0
checking target system type... x86_64-apple-darwin13.1.0
checking if you are configuring for another platform... no
checking for standard CFLAGS on this platform... -fpascal-strings -fno-common -Wno-four-char-constants -Wno-unknown-pragmas -Dmacintosh
checking for gcc... gcc
checking whether the C compiler works... no
configure: error: in `/Users/myName/Desktop/bochs-2.6':
configure: error: C compiler cannot create executables
See `config.log' for more details

不知如何提取config.log的有效信息，直接将文件挂在这里了

Answer 1

试试这个：
CFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future" ./configure ...
如果还是不行就试试：
CC='clang -Wno-error=unused-command-line-argument-hard-error-in-future' ./configure ...

不过话说回来，如果你要装bochs，最好用Homebrew，装好这个之后用brew install bochs就行了。

Answer 2

我觉得是缺少一些以来库，但我无法给出具体是哪些东西。
根据检索，你可以先尝试安装：
brew install sdl
然后记得在你的编译目录里运行：
make distclean
再重新编译安装。

你的 gcc 实际上是 clang。configure 脚本给了一个它不支持的参数过去。可能是版本的问题。你可以试试 CFLAGS='-Wunused-command-line-argument-hard-error-in-future' ./configure。

或者把 CC 设置成 clang 试试？

Answer 4

brew安装gcc，设置环境变量CC为gcc试试。brew有多个gcc的版本可以选择，4.8，4.7，选择一个好了，如果还出错，继续贴log吧
