I already have xcode installed on OSX Yosemite. I have also run it and accepted terms and conditions.
I can also do
gcc --version and I see
Configured with: --prefix=/Applications/Xcode.app/Contents/Developer/usr --with-gxx-include-dir=/usr/include/c++/4.2.1 Apple LLVM version 7.0.0 (clang-700.1.76) Target: x86_64-apple-darwin14.5.0 Thread model: posix
Now if I do
wget http://apache.mirrors.pair.com//httpd/httpd-2.4.17.tar.bz2 brew install pcre tar zxvf httpd-2.4.17.tar.bz2 cd httpd-2.4.17 ./configure
The error I get is
Configure: configure: Configuring Apache Portable Runtime Utility library... configure: checking for APR-util... yes checking for gcc... /Applications/Xcode.app/Contents/Developer/Toolchains/OSX10.10.xctoolchain/usr/bin/cc checking whether the C compiler works... no configure: error: in `/Users/abhi/Downloads/httpd-2.4.17': configure: error: C compiler cannot create executables See `config.log' for more details
Why can't the C compiler create executable? I showed you that the C compiler is installed correctly on my machine.
