Code Sample

wine: glibc >= 2.3 without NPTL or TLS is not a supported combination.
It will most likely crash. Please upgrade to a glibc with NPTL support.

I do not think this warning is benign - i.e. It affects the running of certain apps, seriously.

Tested with WINE versions:
0.9.37 (1 month ago)
0.9.41 (Just today)

So far, I have only one clear example:
Mozilla Firefox 2.0.0.3 win32
WINE on Debian Sid (Glibc 2.5 with NPTL): Runs fine, to the extent that Flash Player 9 installs and plays Flash videos (youtube.com) successfully.
WINE on DSL (Glibc 2.3.2 without NPTL): Timeout with all sites.

We can see Glibc's configuration by running (literally):
`/lib/libc.so.6`

NPTL needs a 2.6 kernel (compiled with at least gcc 3), no way around that..

I've seen RHEL kernels with version strings such as '2.4.2x-blabla-nptl' so from this I gather that NPTL on kernel 2.4 is at least possible in RHEL. I don't know whether NPTL support is in the mainline kernel - is it supported in the latest 2.4.34?

I was wondering about this myself, when I tried out wine0.9.4x.uci that you submitted, and went looking around for some way to get an updated glibc with NPTL somewhere. I just read that NPTL wasn't supported before 2.6 (wiki), as Curaga noted.

Well, Redhat kernels are very far from vanilla ones.. They patch and backport them so much it would actually be stabler to use newer vanilla ones..
