>> I am embedding SM38 on Linux statically, and now I need to port it to Win. Are you saying that you managed to statically link to the NSPR libs using mingw64, so that you did not have to deploy the DLLs, or you could NOT do that neither with mingw64 nor msvc?

Bug 1176787 https://bugzilla.mozilla.org/show_bug.cgi?id=1176787 is 
related to this, though I'll freely admit that I don't understand most 
of what is being discussed there.

I believe one issue is that if you're linking a static js lib that 
includs a static nspr, then things will break if you link against 
something else that uses nspr (because you'll be using two copies, and 
they'll fight over TLS, or something?) If everything links against a 
dynamic NSPR, you should be ok.

I think?

But I don't even really know what mingw64 is. Does that imply you're 
using gcc? Or are you using mingw64+cl.exe? (Is that even a meaningful 
question?)

I would love to have all of these compiling and linking issues resolved 
for the JS lib, but realistically I'm not going to be spending much time 
on it any day soon. If you have identified specific fixes needed in the 
standalone source release tarball, file a bug and CC me (:sfink) and 
I'll make sure they get in (assuming I can convince myself they don't 
break other scenarios.)

Thanks!
