Building image failed, but build log showed no real error

For Developers
1

Hi,

I cloned openwrt source, and was trying to build a custom image. The build took a long time, but failed eventually. The error log didn't seem to show anything useful. Could someone help me identify which step specifically failed it?

I tried twice, and it failed twice. Doesn't seem to be random. I was building an x86-64
22.03.3 image, on an x86-64 machine.

This is from the tail of the error log:

Sure it does:

Try make -j1 V=sc to increase the verbosity level. When it fails, you will need to trace backwards through the output to put a finger where it fails (could be a long way back).

It’s up to you to find where it fails. Most times, it is usually quite evident and quickly resolved.

Thanks for the help.

That log was generated with V=sc, so it was as verbose as it could be.

That particular line seems to result from a previous build error and not the cause of the error, which I'm unable to find.

4

Try a make clean before starting up the next build.

This might help: https://openwrt.org/docs/guide-developer/toolchain/use-buildsystem#spotting_build_errors

This was a fresh build after clone, without any previous build result.

6

But did you include -j 1 also, not only V=sc? That is also needed otherwise because of parallel compiling you won't have the error message belonging to the same error bundled together.

Oh, thanks for the heads up. Because of parallelism, the actual error message was probably pretty far away. I will try -j 1 and see if it's more obvious.

Thanks.
