編譯Python 2.7.2與谷歌perftools

Question

我有一個debian擠壓操作系統（64位）。我想用google-perftools來使用python。爲了執行該操作，我使用選項「-lctmalloc」編譯了自己的Python 2.72。但我得到一些錯誤。

1. 我安裝libuwind因爲谷歌-perftool詢問這個包在使用64位
2. 我安裝了所需的所有包：

步驟：

> 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 

，這是什麼我得到了：

我真的不明白這個錯誤，當我沒有CFLAGS =' - ltcmalloc'完全相同時，我可以編譯。 謝謝你的幫助。

Answer 1

使用LDFLAGS

-ltcmalloc

，它需要POSIX線程的支持。

-lpthread
