[AudioI] Error for FullDuplex

[Matt Flax]

I think you're after pkg-config here.

 

For the particular library you're compiling against, if it has a pc file, then pkg-config will tell you the required preprocessor flags and linking libraries.

 

In your code you will need to include, something like this :

 

#include <ALSA/ALSA.H>

 

Then you can integrate the necessary preprocessor directives like so :

 

pkg-config --cflags gtkIOStream

 

If you an manually creating the Makefile and not using autotools Makefile.am nor the cmake equivalents, then you can manually do it like so :

 

g++ `pkg-config --cflags gtkIOStream`  fileName.C
 

 

Or you can put preprocessor directives and libraries on the same line :

 

g++ `pkg-config --cflags --libs gtkIOStream` fileName.C
 

 


 

 

If you want to use autotools to build your project, then there is a preprepared autotools C++ project here : https://github.com/flatmax/Cplusplus


 

More specifically I've created a branch which integrates gtkIOStream into the autotools project :

 

https://github.com/flatmax/Cplusplus/tree/gtkIOStream

 

The include file tests for the inclusion of ALSA.H : https://github.com/flatmax/Cplusplus/blob/gtkIOStream/include/Test.H#L32

 

The src file tests for linking against libgtkiostream by instantiating Sox : https://github.com/flatmax/Cplusplus/blob/gtkIOStream/test/RunTest.C#L35

 


 

 

First start by confirming you can build it and run the test/RunTest output. Then integrate your code, sources into the src directory, includes in the include directory, tests in the test directory, applications in the applications directory.

 

I hope that helps.

Thanks for the suggestion! but the directory is all caps and the .H/.h is more of a preference. We attempted your solution regardless but yielded the same results.

Shouldn't that be the in lower case, ie "alsa/alsa.h"??

So we started getting an error with the line #include “ALSA/ALSA.H”
 
 Error says
 Fatal error: ALSA/ALSA.H no such file or directory.
 
 I couldn’t find anything on the forums :/
 
 We made sure that gktiostream is properly installed and that the directory was included. 
 
 Any suggestions to remedy this? 
 
 Thanks!
