I'm trying to link directly to the csound dll without needing to use 
pexports but I can't seem to do it. This is what I'm trying:

D:\MyDocuments\Lectures\CPAA>g++ CsoundConsole.cpp -o test.exe 
-I../../SourceCode/csound5/csound5/H
-L../../SourceCode/csound5/csound5 -lcsound32.dll.5.1

If I replace -lcsound32.dll.5.1 with -lcsound32 it works fine. Any 
ideas? csound32.dll.5.1 is definitely in the right directory.

Rory.

I'm assuming you forgot to add a -l before Csound32... if so then how is 
your command any different to my one?

Yours
 > g++ -o blah  blah.c  -L/dll/dir Csound32.dll.5.1

Mine
 > g++ CsoundConsole.cpp -o test.exe
 > -I../../SourceCode/csound5/csound5/H
 > -L../../SourceCode/csound5/csound5 -lcsound32.dll.5.1

When running either command I get the same error about not being able to 
find csound32.dll.5.1 even though I'm sure it's there. Is there any 
chance that MinGW needs the dll to have a dll extension?

Rory.

Now I get the following errors:

D:\MyDocuments\SourceCode\Csound5\csound5>g++ CsoundConsole.cpp -o 
test.exe -I./H csound32.dll.5.1

CsoundConsole.cpp:28:2: warning: no newline at end of file

The other strange thing is that if I use a -L and pass the directory 
that holds csound.dll.5.1 it never finds it.

Rory.

Thanks Victor, I wasn't aware of that.

Rory.

Thanks John. I will try that and see if it works.
