gperftools

安装 gperftools

https://github.com/gperftools/gperftools
编译：
执行自动生成的时候出现错误提示:

sh autogen.sh
configure.ac:163: error: possibly undefined macro: AC_PROG_LIBTOOL
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation

需要安装库 libtool

sudo apt-get install libtool 

编译静态库

./configure --disable-shared CXXFLAGS=-g && make

使用时加上编译选项

 -fno-builtin-malloc -fno-builtin-calloc -fno-builtin-realloc -fno-builtin-free
