編譯gd時報gd_png.c:16:53: error: png.h: No such file or directory錯誤

版本號：gd-2.0.35

解壓路徑：/usr/local/src/gd-2.0.35

make時報錯：

gcc -DHAVE_CONFIG_H -I. -I. -I. -I/usr/local/freetype/include/freetype2 -I/usr/local/freetype/include -I/usr/local/freetype/include -I/usr/local/jpeg/include -g -O2 -MT gd_png.lo -MD -MP -MF .deps/gd_png.Tpo -c gd_png.c -fPIC -DPIC -o .libs/gd_png.o
gd_png.c:16:53: error: png.h: No such file or directory
gd_png.c:47: error: expected specifier-qualifier-list before ‘jmp_buf’
gd_png.c:54: error: expected ‘)’ before ‘png_ptr’
gd_png.c:82: error: expected ‘)’ before ‘png_ptr’
gd_png.c:92: error: expected ‘)’ before ‘png_ptr’

.....

解決辦法：

vi /usr/local/src/gd-2.0.35/gd_png.c
將把下面1個值，修改爲後面的

#include "png.h" --> #include "/usr/local/libpng/include/png.h"

然後再make&&make install就可以了

注：include ""雙引號裏包含的是libpng安裝的路徑裏的include文件夾裏的png.h文件
