linux - 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

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

Try this:
CFLAGS="-Wno-error=unused-command-line-argument-hard-error-in-future" ./configure ...
If that still doesn’t work, try:
CC='clang -Wno-error=unused-command-line-argument-hard-error-in-future' ./configure ...

But having said that, if you want to install bochs, it is best to use Homebrew. After installing this, just use brew install bochs.

Answer 2

I think there are some libraries missing, but I can’t tell you what they are.
According to the search, you can try to install it first:
brew install sdl
Then remember to run in your compilation directory:
make distclean
Then recompile and install.

Your gcc is actually clang. The configure script was given an argument it didn't support. Maybe it's a version issue. You can try CFLAGS='-Wunused-command-line-argument-hard-error-in-future' ./configure.

Or try setting CC to clang?

Answer 4

Brew install gcc, set the environment variable CC to gcc and try. Brew has multiple gcc versions to choose from, 4.8 and 4.7. Just choose one. If you still get an error, continue posting the log
