安装google perftools

最近要看一下一个程序的性能，计划用google perftools测试一下．下面是我安装的过程一个流水说明，没有含量，我就是看着耍．在git上https://github.com/gperftools/gperftools下载下来，我这里版本是gperftools-2.5.tar.gz，解压后进入目前，看ＩＮＳＴＬＬ，发现这里有一段话：

*** NOTE FOR 64-BIT LINUX SYSTEMS

The glibc built-in stack-unwinder on 64-bit systems has some problems
with the perftools libraries.  (In particular, the cpu/heap profiler
may be in the middle of malloc, holding some malloc-related locks when
they invoke the stack unwinder.  The built-in stack unwinder may call
malloc recursively, which may require the thread to acquire a lock it
already holds: deadlock.)

For that reason, if you use a 64-bit system, we strongly recommend you
install libunwind before trying to configure or install gperftools.

明显啊，要安装 libunwind．这个好办

lhw@lhw:~/projects/gperftools-2.5$ sudo apt-cache search libunwind

android-libunwind - libunwind for Android
android-libunwind-dev - libunwind for Android - Development files
libunwind-dev - library to determine the call-chain of a program - development
libunwind-setjmp0 - libunwind-based non local goto - runtime
libunwind-setjmp0-dbg - libunwind-based non local goto - runtime
libunwind-setjmp0-dev - libunwind-based non local goto - development
libunwind8 - library to determine the call-chain of a program - runtime
libunwind8-dbg - library to determine the call-chain of a program - runtime
libunwind8-dev - library to determine the call-chain of a program - development

直接安装

 sudo apt-get install libunwind-dev

很有可能直接安装libunwind8就可以了，不用安装开发者版本的．但我也觉得多安点还好，不洁癖，装上也不大，直接装了．

然后就

.configure
make
sudo make install

然后就搞定了．
