i've created a .dll with cygwin
i'd like now to create a simple program under msvc++
that use functions of this dll
when i compile my very simple program, i get those
errors at link step: unresolved external symbol _foo
where foo is a function of my dll
so how can i use this dll in my program ? maybe a
foo.lib is missing (is there a way to create it from a
dll ?), or maybe is there another way to do so ?
You need an import library to link against, yes. See
<http://cygwin.com/cygwin-ug-net/dll.html> for instructions
on building DLLs and import libraries with Cygwin. Keep in
mind that if you're using cygwin1.dll in your resulting DLL
(i.e. you're not using the '-mno-cygwin' flag for gcc) then
you may end up with 2 C runtimes in your final executable.
See the FAQ and <http://cygwin.com/ml/cygwin/2003-07/msg01761.html>
for some information on this. There's plenty more in the email
archives too if you're interested.
