本文介绍如何正确设置编译参数，包括使用./configure指定CC编译器路径的方法，并强调了通过环境变量设定编译参数的做法不被推荐。

./configure CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3"

CXXFLAGS="-g -O2 -std=c++11"
c++0x

./configure CC="/usr/bin/gcc-4.6" CXX="/usr/bin/g++-4.6" CFLAGS="-ggdb3 -O0" CXXFLAGS="-ggdb3 -O0" LDFLAGS="-ggdb3"

CC="gcc-4.5" ./configure
CC="gcc-4.5" make

This works, but is discouraged. The recommended way to specify CC is in an argument to configure, not in the environment. In other words, you should do 
"./configure CC=/path/to/desired/compiler"
