Re: CRT runtime error with .Net 2003

Hi Brian,

I have never tried to use pthread as a static lib, so I can't help you here.
But if you use the pthread as a dll, and if you use the /MT flag,
one of it's tests will fail, so for a dll you have to use the /MD flag.

Nevertheless, you should use for your app the same flag /MT or /MD
for _all_ the modules involved, otherwise you can get into trouble.
