Please tell me if any bugs thanks Bookaa From: Amaury Forgeot d'Arc Sent: Saturday, April 21, 2012 3:51 PM To: bookaa Cc: pypy-dev@python.org Subject: Re: [pypy-dev] output readable c 2012/4/21 bookaa <rorsoft@gmail.com> thank you for encourage! as for the bugs, please tell me exacty how to run, which test. My system is Win7, pypy tests get many error even without any change. Tests in the translator/c directory should pass. For example: c:\python27\python pytest.py pypy\translator\c\test\test_backendoptimized.py And to translate the small (!) "hello world" target: c:\python27\python pypy\translator\goal\translate.py -O2 pypy\translator\goal\targetnopstandalone.py -- Amaury Forgeot d'Arc
