linux64位编译php遇到configure: error: GD build test failed. Please check the config.log for details

This error occures becuase the linker (ld) cannot find the jpeg library. You can fix this problem by editing the config.nice file inside the php directory and adding
LDFLAGS='-L/path/to/lib' \   (注释：linux64位机器 此处应写为LDFLAGS='-L/usr/lib64' \)
above the ./configure \

For example is your libjpeg.so resides inside /usr/local/lib, you'd add -L/usr/local/lib.

Once you've edited the file, remove config.cache and run ./config.nice, after that make; make install; should work.
