valgrind 安装使用 failed to start tool 'memcheck' for platform 'amd64-linux'

valgrind: failed to start tool 'memcheck' for platform 'amd64-linux': No such file or directory

#wget http://www.valgrind.org/downloads/valgrind-3.13.0.tar.bz2
#tar xvf valgrind-3.13.0.tar.bz2
#cd valgrind-3.13.0

#./autogen.sh      缺少这步会导致failed to start tool 'memcheck' for platform 'amd64-linux'
#./configure --prefix=/usr/local/webserver/valgrind
#make
#sudo make install

[work@localhost bin]$ ./valgrind --tool=memcheck --leak-check=yes --show-reachable=yes ./out
valgrind: failed to start tool 'memcheck' for platform 'amd64-linux': No such file or directory

添加步骤 #./autogen.sh 后正常。

[work@localhost bin]$ ./valgrind --tool=memcheck --leak-check=yes --show-reachable=yes --log-file=leak.log ./out
