第一步：#locate libpng 我的电脑显示如下： /lib/i386-linux-gnu/libpng12.so.0 /lib/i386-linux-gnu/libpng12.so.0.46.0 /usr/share/doc/libpng12-0 /usr/share/doc/libpng12-0/ANNOUNCE /usr/share/doc/libpng12-0/KNOWNBUG /usr/share/doc/libpng12-0/README.Debian /usr/share/doc/libpng12-0/README.gz /usr/share/doc/libpng12-0/TODO /usr/share/doc/libpng12-0/changelog.Debian.gz /usr/share/doc/libpng12-0/copyright /usr/share/doc/libpng12-0/libpng-1.2.46.txt.gz /usr/share/doc-base/libpng12 /var/lib/doc-base/documents/libpng12 /var/lib/dpkg/info/libpng12-0:i386.list /var/lib/dpkg/info/libpng12-0:i386.md5sums /var/lib/dpkg/info/libpng12-0:i386.postinst /var/lib/dpkg/info/libpng12-0:i386.postrm /var/lib/dpkg/info/libpng12-0:i386.shlibs 第二步：建立链接#ln -s /lib/i386-linux-gnu/libpng12.so.0 /lib/i386-linux-gnu/libpng.so 第三步：修改Makefile文件，#gedit Makefile(或者 #vi Makefile),在LIBS后面添加-L/lib/i386-linux-gnu -lpng这两项 重新make后，成功！  （编辑：开发网_郴州站长网）
