LAMP环境编译 编译libpng时出错 附上错误代码求助！！！
 

/usr/bin/ld: /usr/local/lib/libz.a(crc32.o): relocation R_X86_64_32 against `.rodata' can not be used when making a shared object; recompile with -fPIC
/usr/local/lib/libz.a: could not read symbols: Bad value
collect2: ld returned 1 exit status
make[1]: *** [libpng12.la] Error 1
make[1]: Leaving directory `/lamp/libpng-1.2.31'
make: *** [all] Error 2

一般是64 位 电脑才会出现。


解决方法如下：

cd zlib-1.2.3 //进入zlib目录

CFLAGS="-O3 -fPIC" ./configure //使用64位元的方法进行编译

make clean
make && make install

然后再重新安装libpng
