Subject: linking ocaml in multithreaded shared dll app
Date: Tue, 07 Nov 2000 11:19:08 -0800 [thread overview]
Message-ID: <3A0855AC.77F9C627@artemis.arc.nasa.gov> (raw)
I'm trying to link the ocaml library into a Windows NT 4.0, MS VC++ 6.0
application that uses MFC in a shared dll (because another library,
OpenInventor, has to be linked this way).
I'm getting an unresolved external symbol error for the symbols
__pctype, ___mb_cur_max, and __dosmaperr from files like win32.obj,
read.obj, write.obj, etc. (complete text at bottom).
I'm not a MSVC++ expert, but I'm guessing that the libunix library is
compiled to be linked with a statically-linked MFC library. Is this
right? Is there anyway to compile it to link to a dynamically-linked MFC
library?
Or is there something else going on?
Charles
Here is the linker output (ignore the first few Maestro errors, I'm
porting that):
