Qt4.8.5编译qvfb出现undefined reference to `png_create_write_struct'问题解决办法

转载于：http://www.linuxidc.com/Linux/2014-02/97344.htm

操作系统：Ubuntu12.04

QT版本：4.8.5

由于系统原因，今天要重新编译QT，在编译PC版的qvfb的make步骤时，出现了如下错误：

截图如下：



解决办法：

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！
