我正在尝试memcheck我写的C python扩展,但是我在设置valgrind以使用python时遇到了麻烦.我真的很感激一些建议.仅供上下文使用,这是Ubuntu 13.10,python 2.7.5+和valgrind 3.8.1.
根据Readme.valgrind我的建议,我做了以下.
1)用.下载python源码
sudo apt-get build-dep python2.7
apt-get source python2.7
2)应用代码补丁,即"在Objects/obmalloc.c中取消注释Py_USING_MEMORY_DEBUGGER".
3)应用抑制补丁,即"取消注释Misc/valgrind-python.supp中的行,以抑制PyObject_Free和PyObject_Realloc的警告"
4)编译python与
./configure --prefix=/home/dejan/workspace/python --without-pymalloc
make -j4 install
请注意,我做了2和3,而README.valgrind说做2或3 ...更多不能伤害.
现在,让我们在一些示例python代码中对此进行测试 test.py
print "Test"
让我们用这个脚本在python上运行valgrind
valgrind --tool=memcheck --leak-check=full --suppressions=python2.7-2.7.5/Misc/valgrind-python.supp bin/python test.py
出乎意料的是,仍然有来自valgrind的大量报告,其中第一个报告(以及更多关注报告)
