Re: using a dll created by cygwin in msvc++

re

Thank you, in fact, i want to compile a qt program
under win using a dll i've created with cygwin

so with cygwin i get a cygfoo-0.dll and a libfoo.a

so with my qt program under win, i do: qmake -f
Makefile foo1.pro

I edit Makefile to add to LIBS: (foo needs ssl, crypto
and z)
"libcygwin.a" "libfoo.a" "libssl.a" "libcrypto.a"
"libz.a" 

then nmake -f Makefile
(i don't know if my method is good...)

but i get those errors: 
libcrypto.a (b_print.o) : error: unresolved external
symbol ___umoddi3
libcrypto.a (bn_word.o) : error: unresolved external
symbol ___umoddi3
libcrypto.a (b_print.o) : error: unresolved external
symbol ___udivdi3

Someone understands this error ?
umoddi3 and udivdi3 are not in cygwin maybe ?

thanks
enzo
