Re: [Mingw-users] cannot create shared DLL due to rpcrt4

[Benno S. <ben...@go...>]

Hi Brian and others,
I compiled linuxsampler on mingw and tried to to create shared lib for it (
liblinuxsampler DLL) but it
still does not work. here is the Makefile we are using
http://cvs.linuxsampler.org/cgi-bin/viewcvs.cgi/linuxsampler/src/Makefile.am?rev=1.24&content-type=text/vnd.viewcvs-markup

and here you see the full compile output,

http://download.linuxsampler.org/dev/win32_probs/linuxsampler-compile-out.txt

the relevant part is from line 477 to 514

on the contrary libgig used by linuxsampler compiles fine as a shared DLL.
here you can see the full compile log:
http://download.linuxsampler.org/dev/win32_probs/libgig-compile-output.txt

the linking part which generates the DLL is at line 71


any idea how to convince autotools to generate liblinuxsampler.dll instead
linuxsampler.a
when compiling linuxsampler ?

thanks in advance,
cheers,
Benno
