我一直在为iOS进行大量的不同库的交叉编译,直到iOS5没有问题.好吧,显然我的问题是,iOS5 SDK不再包含GNU gcc编译器了.只有llvm和clang可用.
我的问题是,我无法完成运行任何库的'configure'脚本.它始终失败:
configure: error: C preprocessor
"/Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc" fails sanity check
gcc只是llvm编译器的符号链接.如果我将其设置为clang,则会产生相同的错误.(只是使用更好的语法错误表示)
这是config.log的重要部分:
configure:3338: checking how to recognise dependent libraries
configure:3514: result: pass_all
configure:3993: checking how to run the C preprocessor
