[SOLVED] g_task_set_static_name not present in glib

[mrmrfallback]

Hello everyone! I am currently trying to run an unofficial software that requires a function called "g_task_set_static_name" in glib (aka I'm trying to run DaVinci Resolve).
Upon running it, I get this error:

Code: Select all

/opt/resolve/bin/resolve: symbol lookup error: /opt/resolve/bin/../libs/libgdk_pixbuf-2.0.so.0: undefined symbol: g_task_set_static_name

which APPEARS to be a glib function (I could be wrong) but running

Code: Select all

nm -gD /usr/lib64/libglib-2.0.so | grep g_task

shows no output. On the other hand running

Code: Select all

nm -gD /usr/lib64/libgdk_pixbuf-2.0.so.0 | grep g_task_set_static_name

I get

Code: Select all

U g_task_set_static_name

what is happening?
(Before anyone asks, yes I did face the other error multiple users have been facing w/ Resolve and I solved it the same way OP of the post did. Resolve worked for a few weeks before this new error popped up.)

Welcome to the forums.

Code: Select all

/opt/resolve/bin/resolve: symbol lookup error: /opt/resolve/bin/../libs/libgdk_pixbuf-2.0.so.0: undefined symbol: g_task_set_static_name

Resolve bundled a copy of gdk_pixbuf that depends on a glib function, but did not link to a library to provide that function.

which APPEARS to be a glib function (I could be wrong)

Based on the name, that seems like a reasonable guess to me.

but running

Code: Select all

nm -gD /usr/lib64/libglib-2.0.so | grep g_task

shows no output.

That is consistent with the error. Your installed glib does not define this function. This could be because the function is in some other shared object, or it could be an abandoned method that is no longer implemented.

On the other hand running

Code: Select all

nm -gD /usr/lib64/libgdk_pixbuf-2.0.so.0 | grep g_task_set_static_name

I get

Code: Select all

U g_task_set_static_name

what is happening?

That indicates the installed gdk_pixbuf also needs this symbol, and expects it to be defined externally. Since the system gdk-pixbuf needs the symbol, that suggests the symbol was not withdrawn by upstream. The symbol seems to be defined by libgio-2.0.so for me.

What is the output of emerge --pretend --verbose dev-libs/glib x11-libs/gdk-pixbuf ; scanelf --needed /usr/lib64/libgdk_pixbuf-2.0.so.0 /opt/resolve/bin/../libs/libgdk_pixbuf-2.0.so.0? Can you determine what version of gdk-pixbuf was bundled with Resolve? If you force Resolve to use the system gdk-pixbuf, does it work?

I already moved my system's libdgk_pixbuf to /opt/resolve/libs (so it's the latest)

Is Resolve still broken after you replaced gdk-pixbuf? If so, is Resolve shipping an outdated libgio?

Solved! Turns out Resolve was indeed shipping an outdated version of libgio...I wonder how many problems users will have to find until BlackMagic updates our libs...
Thank you for helping me!

This thread helped me launch Resolve again, after it not working for a week, but now it's extremely unstable. It crashes after a few seconds of use. Did you find that copying in gdk-pixbuf libs into Resolve's lib directory affected it in a positive way?

I am desperate to get this working for a project.
