configure:error:GDbuildtestfailed.Pleasechecktheconfig.logfordetailsThis 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.
