#內存泄露# #valgrind#valgrind-3.15.0 編譯&&交叉編譯

環境準備

valgrind-3.15.0 官網下載地址：http://valgrind.org/
編譯環境:ubuntu16.04 x64
開發平臺：TDA2X

下載好valgrind-3.15.0.tar.bz2文件後進行解壓

tar xvf valgrind-3.15.0.tar.bz2

安裝automake 

apt-get install automake 

運行autogen.sh開始配置

valgrind-3.15.0
./autogen.sh

 

配置

修改配置文件configure，否則配置指定的交叉編譯工具可能以下錯誤會報

checking host system type... arm-unknown-linux-gnu checking for a supported CPU... no (arm) configure: error: Unsupported host architecture. Sorry
 找到armv7修改爲 armv7*|arm*

     armv7*)
	{ $as_echo "$as_me:${as_lineno-$LINENO}: result: ok (${host_cpu})" >&5
$as_echo "ok (${host_cpu})" >&6; }
	ARCH_MAX="arm"
	;;

     armv7*|arm*)
	{ $as_echo "$as_me:${as_lineno-$LINENO}: result: ok (${host_cpu})" >&5
$as_echo "ok (${host_cpu})" >&6; }
	ARCH_MAX="arm"
	;;

由於我們需要交叉編譯因此需要配置指定的編譯工具

 ./configure --host=arm-linux CC=arm-linux-gnueabihf-gcc CPP=arm-linux-gnueabihf-cpp CXX=arm-linux-gnueabihf-g++ --prefix=/opt/valgrind

1. CC、CPP、g++指定爲交叉編譯的arm版本編譯器
2. --prefix：指定valgrind編譯生成的可執行文件的保存路徑，注意該路徑必須和開發板上最好存放valgrind的路徑一致，否則可能會報"valgrind: failed to start tool 'memcheck' for platform 'arm-linux': No such file or directory"等類似錯誤。然而其實本質上的問題是執行valgrind時，沒有找到valgrind的lib庫！！！我們在lib下面可以看到還有一層目錄valgrind，這時候我們在開發板/etc/profile文件中添加一行
          

   export VALGRIND_LIB=/opt/valgrind-3.15.0/lib/valgrind

   以下爲lib/valgrind看的相關庫文件

當然我們還可以在PATH="/usr/bin:/usr/sbin:/bin:/sbin:/app/bin:/opt/valgrind-3.15.0/bin",黑色爲一些系統路徑配置(根據你自己profile裏面PATH路徑），添加後面紅色部分就行了，執行下source /etc/profile ,就可以當valgrind命令使用了

 

編譯

sudo make
sudo make install

運行

拷貝編譯的文件到開發版，最好目錄爲編譯目錄以防止找不到庫，當然也可以

export VALGRIND_LIB=/opt/valgrind-3.15.0/lib/valgrind

添加當前valgrind的路徑

export PATH=/opt/valgrind-3.15.0/bin:$PATH

運行....

    valgrind --tool=memcheck --leak-check=full ./xxx(需要監控的程序)
