gegl-0.3 @0.3.34_14+x11: OpenCL link error

[jsalort (Julien Salort)]

Gegl fails to build on Ventura with Apple M1. As far as I can see, this is another build failure, it differs from the other two opened tickets: #66777 and #66233.

The error is

:info:build dyld[28377]: symbol not found in flat namespace '_clGetContextInfo'

I attach the complete main.log.

Perhaps the warning in the log is relevant:

ld: warning: -undefined dynamic_lookup may not work with chained fixups

See #66660 for how I fixed that in php-opcache.

You're right, adding this:

if {[vercmp ${macosx_deployment_target} >= 11]} {
	configure.ldflags-append -Wl,-no_fixup_chains
}

does indeed get past that link error. Thanks for that.

You then get into the error due to the new libraw that we have seen elsewhere.

[kencu (Ken)]

looks like gentoo has a patch for the libraw thing, for the latest gegl at least

​https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=e37f1398f63db9f2a6fe4133599a7169f6780e38

and the messaging says there is something already in gegl upstream to fix it too, so perhaps we should find that.
