Speex dev - Apr 2006 - Unable to obtain a DLL.

Hello,

I have the 1.0.5 and 1.1.12 versions of Speex. The problem is that when 
I compile Speex using MinGW and MSys using:

./configure --enable-shared --prefix=/c/bgw/

I don't get neither a DLL file nor a .a library although the compile is 
successful. Also I must notice that the headers for Speex are installed 
correctly in the /c/bgw/ directory as specified by the prefix, and I did 
previously compiled the 1.0.5 version under vs2003 (in its separate 
folder, of course from the 1.0.5 MinGW).

Am I missing something trivial?

Maybe not.

Jean-Marc, to generate a DLL using MinGW, you need to add -no-undefined
to the link line. For libsndfile, I do this using the following in
the Makefile.am file:

    libsndfile_la_LDFLAGS = -no-undefined -version-info @SHARED_VERSION_INFO@
@SHLIB_VERSION_ARG@

You probably need something like this in your Makefile.am.

Cheers,
Erik

Could you tell me more about what that flag does? Any side effects? Is
it gcc-specific?
