从官网下载针对12.04的版本的texstudio: http://texstudio.sourceforge.net/
安装deb包:sudo dpkg -i texstudio_xx.deb
运行提示找不到lib:
libpoppler-qt4.so.3: cannot open shared object file: No such file or directory
查看textstudio所需库的情况: ldd -v /usr/bin/texstudio | grep qt
安装库 libpoppler-qt4.so.3 : sudo apt-get install libpoppler-qt4-3
问题解决!
