typelib won't build #2

Closed grindhold closed 7 years ago

grindhold commented 7 years ago

sorry to bother again, but the typelib target won't yield anything useful. Is there any path-stuff i have to set manually?

This looks like your gobject-introspection installation is broken. Does it work when building any other software?

grindhold commented 7 years ago

yup, i regularly build typelibs for my own libraries, libgtkflow libhttpseverywhere and liboparl. recently i built a GIR file from libgegl-0.3's headers through g-ir-scanner a which g-ir-scanner also points to my regular g-ir-scanner from the distro in /usr/bin, not any self-build experimental stuff

sdroege commented 7 years ago

That's curious. Can you put your /usr/bin/libtool somewhere, especially around line 2459?

    exit $?
}

the version-function as requested. but isn't its output far more valuable? :) i am on debian testing btw.

sdroege commented 7 years ago

I'm on Debian unstable, but didn't dist-upgrade since a while

So the problem here is not libtool actually, but that the printf there is printing to a bad file descriptor. So whatever is calling libtool is doing something bad with stdout. That would be gobject-introspection I guess. I'm running 1.53.2-4

sdroege commented 7 years ago

Any new insights here?

grindhold commented 7 years ago

not yet, unfortunately. didn't get to it

it now works on both of my test systems. i assume there has been a relevant fix incoming via distribution-updates.

i now have

And now that it works: Nice work you've done there. I think i will code my next library in Rust to try it out.

sdroege commented 7 years ago

Weird. Can you check if there were any updates in versions in the meantime, and which? I would add this as a requirement to the README then.
