Compile gcc4.7 lambda expressions in centos and it is not easy to love you. STL provides many algorithms but does not provide anonymous functions. it is a sin! The story of this article begins. C ++ 0x brings us a spring breeze and provides lambda expressions. we can finally write programs like c. Int a, B; for_each (v. begin (), v. end (), [=] (int & it) {it = it * a + B;}); because www.2cto.com is usually developed under vs2010, it is only noticed during deployment, the gcc version 4.4 in centos6 does not support lambda. it should be supported by at least 4.5. Since 4.7 is coming, compile it. After a google attack, many of my colleagues wrote complex statements and made them more complex. I had a lot of detours and hoped to provide some help to others! First, get the code out.

Slow down the machine .. Many articles say that it is irrational to download the source code of the three libraries, such as the archive file, and compile the source code by yourself, which wastes a lot of time, because we may encounter version problems and path problems when downloading, installing, and installing on our own, a good solution should be used. /contrib/download_prerequisites, which is automatically downloaded and compiled.
