Compile fails on ppc64le

I cannot imagine what we could have done wrong, though it could be a problem in the header file ordering. Can you try compiling with http://ix.io/2bLM ?

[leigh123linux]

@ammen99 The patch doesn't help

https://leigh123linux.fedorapeople.org/pub/txt/wf-recorder_error.txt

It fails to compile on f30 and f31 ppc64le using gcc-9.2.1

It compiles ok on ppc64le using gcc-10

I believe this is a compiler/library bug, considering that the project compiles on multiple CPU architectures.

The error messages also indicate problems converting from int to bool, which should work without problems.

[ammen99]

To confirm my suspicion, would it be possible to try compiling with clang?

[leigh123linux]

@ammen99 It builds ok using clang

https://koji.rpmfusion.org/koji/taskinfo?taskID=386648

It's a shame we're not allowed to override the gcc default in fedora.

Well if you manage to work around this, I would be willing to merge the fix, but I have no idea whether this is possible at all.

Could you not disable the package for a specific architecture?
