Last version compilation failed

[UgoPoddine]

Hello Mooner,

How are you ? Thank-you for your work, really appreciated. The today update with the last release of FreeDV on my Raspberry Pi3+ with up do date pi OS 32 bits failed. See the last part of the log in the attachment. Feel free to ask if you need further details.

Best regards @Ugo

This is a known issue. See https://github.com/drowe67/LPCNet/issues/49 and https://github.com/drowe67/LPCNet/pull/50.

As a workaround, you can update LPCNET_BRANCH in build_linux.sh to ms-rpi-build instead of master. Let me know if that doesn't work for you.

Hi Mooner,

The issue was almost known, but till last version (7 days ago) I have always compiled using the build_linux script on the PI without issues No problem at all, I will try the workaround tomorrow morning.

Thanks Best regards, 73 Ugo

Hi Mooner,

the workaround you have proposed allows the compilation to proceed, but not to end correctly : With this change to build_linux.sh :

[..]

change this when working on combined codec2/freedv-gui changes

CODEC2_BRANCH=ms-rpi-build LPCNET_BRANCH=ms-rpi-build

[..]

...this is the final effect :

Please advise. Thank-you Ugo

A few things:

1. CODEC2_BRANCH should still be master. Only LPCNET_BRANCH should change.
2. You may need to rm -rf codec2 LPCNet build_linux before re-attempting the build to clear out anything CMake still has cached.

If you still have issues after (1) and (2) above then I can see about getting 32 bit Raspberry Pi OS running on my 4B for further debugging.

BTW I was able to get a build environment installed on an older Pi and resolve the issue you're having, so definitely try again. 👍

Hi Mooner,

using :

[...]

change this when working on combined codec2/freedv-gui changes

CODEC2_BRANCH=master LPCNET_BRANCH=ms-rpi-build

[..]

I was also able to compile the new version. I will try it this evening.

Thank-you Ugo
