GCC

The GNU Compiler Collection includes front ends for C, C++, Objective-C, Fortran, Java, Ada, and Go, as well as libraries for these languages (libstdc++, libgcj,…). GCC was originally written as the compiler for the GNU operating system. The GNU system was developed to be 100% free software, free in the sense that it respects the user’s freedom.

mozjs185 在哪里?

安装某个东西，cmake的时候，报错如下

-- checking for module 'mozjs185'
--   package 'mozjs185' not found

如往常，copy这个module的名字，然后

# yum search mozjs185

结果是Not Found (废话，如果不是not found，还写这个干啥...) 直接杀到网上找结果。 (more…)

error while loading shared libraries的解决方法

错误提示:

./prog: error while loading shared libraries: xxx.so.0:
cannot open shared object file: No such file or directory

这个提示的意思是没有找到xxx.so.0这个文件,那么首先应该确定下,本机是否存在这个.so文件?如果存在,那么我们可以作出判断,xxx.so.0这个动态链接库所在的文件夹不在搜寻范围内. (more…)
