Question

我有一个debian挤压操作系统（64位）。我想在google-perftools中使用python。为了执行该操作，我使用选项“-lctmalloc”编译了自己的python 2.72。但我得到的错误很少。

我安装了libuwind，因为google-perftool在使用64位
我安装了所有需要的软件包：

步骤：

> sudo apt-get -y install build-essential 
> sudo apt-get -y install zlib1g-dev libxml2-dev libxslt1-dev libssl-dev libncurses5-dev  
> sudo apt-get -y install libreadline6-dev autotools-dev autoconf automake libtool 
> sudo apt-get -y install libsvn-dev mercurial subversion git-core 
> sudo apt-get -y install libbz2-dev libgdbm-dev sqlite3 libsqlite3-dev 
> sudo apt-get -y install curl libcurl4-gnutls-dev 
> sudo apt-get -y install libevent-dev libev-dev librrd4 rrdtool 
> sudo apt-get -y install uuid-dev libdb4.8-dev memcached libmemcached-dev  
> sudo apt-get -y install libmysqlclient-dev libexpat1-dev 
> sudo apt-get -y install google-perftool 
> cd python 
> export CFLAGS='-ltcmalloc' 
> ./configure 
> make

这就是我得到的：

如果没有CFLAGS =' - ltcmalloc'，我真的不明白这个错误，我能够编译。谢谢你的帮助。

Answer 1

使用LDFlags

-ltcmalloc

它需要posix线程支持。

-lpthread

使用google-perftools编译Python 2.7.2
