Hi, I stumbled upon an issue that I'm not sure what the best fix is and wanted to ask people here for opinions.
There are a couple of packages that have a check in the configure script that will check for the presence of the pthread_create function. The check works as far as I understand as follows: * check whether pthread_create is available without a flag * check whether pthread_create is available with -lpthread Now here's the problem: libasan contains a pthread_create function. Therefore the configure scripts will assume that pthread is available. However libasan doesn't contain the full pthread functionality, other functions like pthread_mutex_create aren't available. Therefore: * configure script thinks we don't need -lpthread * application uses pthread functionality that's not in libasan * compilation fails I have first encountered this in sqlite, upstream has now fixed this by checking for a different pthread function (patch came from me): https://www.sqlite.org/cgi/src/info/9c3a0dc2e8bf202c Now I wonder - is this a good solution? I know of at least three other packages (poppler, openldap, p11-kit) that have the same issue and wonder if I should send similar patches or if there's a better / more clean solution to this. (Also I think this stuff should be documented, I'll add this to the FAQ once we agree what the best way forward is. There's another very common asan compilation issue with libtool, I'll document that as well.) -- Hanno Böck http://hboeck.de/ mail/jabber: [email protected] GPG: BBB51E42 -- You received this message because you are subscribed to the Google Groups "address-sanitizer" group.
