Hello, can someone please help me get up and running with the C++ examples on
Windows with mingw - I am trying to build an example with the command

g++ SimpleCsdPlayback.cpp -o main.exe -L "C:\Program Files\Csound6_x64\lib"
-I "C:\Program Files\Csound6_x64\include\csound" -l csound64

.. but minggw responds with a lot of lines like these:

c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe:
C:\Users\user\AppData\Local\Temp\ccHlJyC
c.o:SimpleCsdPlayback.cpp:(.text$_ZNK6Csound14GetSpoutSampleEii[__ZNK6Csound14GetSpoutSampleEii]+0x21):
undefi
ned reference to `csoundGetSpoutSample'
c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe:

Yes - if I specify any other path I will get the message

c:/mingw/bin/../lib/gcc/mingw32/9.2.0/../../../../mingw32/bin/ld.exe:
cannot find -lcsound64

Are you using Visual Studio? Perhaps the csound64.lib doesn't work
with Mingw because it was created with Visual Studio.. it read that in
the past Mingw would only accept .a files, but also read that it
should support .lib files now.
I don't think I have any other linker on my machine (haven't been able
to download Visual Studio).
It seems that it is all functions of csound64.dll that are undefined,
but I haven't changed anything in this file, so they really ought to
be defined..?

Ok! Being a C++ novice I guess I will go with the simpler VS Express
solution. Am currently corona-stuck on an island with poor
phone-Internet, but will go hunting for a better connection.
Thank you both for the help.
Best regards,
Søren
