rpicam-apps-1.5.0 fails to build on an RPi3 #701

Closed juanitotc closed 4 months ago

juanitotc commented 4 months ago

Compiling rpicam-apps-1.5.0 natively 32-bit on an RPi3 using gcc-13.2.0 and against libcamera-0.3.0, the build fails with the error below.

Is there a way to get more debug detail?

Compiling natively 64-bit on an RPi4 using gcc-13.2.0 succeeds.

Can you configure the following meson option and see if it helps:

-Dneon_flasgs=armv8-neon

I'll try that, but if I'm compiling for all versions of RPi using "-march=armv6zk -mtune=arm1176jzf-s -mfpu=vfp", won't that (-mfpu=neon-fp-armv8) conflict?

Edit: I just tried "-Dneon_flags=armv8-neon" and got the same error as the first post.

Ah - even though there were no out of memory errors, adding a large swap file has enabled the build to succeed.

Sorry for the noise...
