./codec2/version.h Not found

[farawaysouthwest]

Hi All,

I'm building an Apple M1 image and I get the following error when building from source. ... /homebrew/Cellar/codec2/1.0.3/include/codec2/codec2.h:32:10: fatal error: 'codec2/version.h' file not found in the M17 build step.

I installed codec2 via homebrew, but it seems to be an incompatible version? Has anyone else experienced this?

The <codec2_root>/include/codec2/version.h is supposed to be generated from <codec2_root>/cmake/version.h.in when building. But it's a small file that you can add with only this:

#ifndef CODEC2_VERSION_H
#define CODEC2_VERSION_H

#define CODEC2_VERSION_MAJOR  1
#define CODEC2_VERSION_MINOR  0
#define CODEC2_VERSION_PATCH  0
#define CODEC2_VERSION       "1.0.0"
#endif

I worked around this by editing this file: /opt/homebrew/Cellar/codec2/1.0.3/include/codec2/codec2.h

...as so:

/*#include <codec2/version.h>*/
#include <version.h>

...such that the now-commented line is the original (L32), and the subsequent is what allowed the build to succeed.

Without the lensing to open a PR myself (nor the time to invest to acquire it), perhaps the above would help @gvanem turn his suggested workaround into a proper fix. 🤞

This should probably be brought up to the attention of the codec2 developpers. I load it like any other library, if it doesn't install itself properly it should not be fixed in SDR++ but instead at the library.
