Re: dllwrap and excluded symbols

[Tim Reed <timr at viaworks dot com>]

The command line I am using for the dll is

dllwrap --target=i386-mingw32 -mno-cygwin --driver-flags -O0 -g
-L/usr/local/lib/ -L/usr/local/i386-mingw32/lib/ -lmsvcrt -lwsock32 -static
-mno-cygwin -v -H -liberty --export-all --output-def viaworks.def
--driver-name gcc -o viaworks.dll -lgmp -lwsock32 -lmsvcrt

And for a compiled program I use

gcc    acoset_test.o acoset.o ../lib/vsp/base64.o ../lib/libvia.a  -O0 -g
-L/usr/local/lib/ -L/usr/local/i386-mingw32/lib/ -lmsvcrt -lwsock32 -static
-mno-cygwin -v -H -liberty -L/usr/local/lib/ -lgmp -lm  -L../lib/ -lvia  -o
acoset_test

At least, that's what my Makefile is generating. You'll note that I'm using
gmp compiled for mingw and the gcc version is 2.95.2 19991024 (release 2).

Using objdump -p I found that malloc is being linked to msvcrt.dll and not
crtdll in both my program and my dll. My dll still links in crtdll because
it uses some functions for entering and exiting the dll code, basically
it's called _GetMainArgs, atexit, _environ_dll, and the like.

I mentioned earlier that removing msvcrt from the dll compilation command
doesn't solve the problem. Do you think using msvcrt and removing crtdll
is the solution? Is that possible?

Hope that tells you something...
