[SOLVED] glib2 missing symbol running gpicview

After updating glib2 2.82.5-1 => 2.84.0-1 I see a new error with gpicview 0.2.5-8

/usr/bin/gpicview: symbol lookup error: /usr/lib/libgio-2.0.so.0: undefined symbol: g_variant_builder_init_static

this seems to occur in a specific context ie run in a detached process with a normal user.

When the same user runs the same command from a terminal the error is not seen.

When sudo is used to change the running user in the detached command the error is not seen.

Downdating to  2.82.5-1 removes this error.

Interestingly, I kind of had the opposite issue (that's how I got here)
I was on 2.82.5-1, tried gimp3, and got the error
gimp: symbol lookup error: gimp: undefined symbol: g_variant_builder_init_static

upgrading to 2.84.0-1 fixed it

run in a detached process with a normal user

What does "detached" mean in this context?
You're likely resolving some dated version of libglib-2.0.so… somehow.

ls -l /usr{/local,/}lib/libglib-2.0.*

@j0lle, no surprises there.
Partial updates are unsupported, gimp was linked against the newer glib that introduced that symbol

Re: [SOLVED] glib2 missing symbol running gpicview

OK detached means running under https://aur.archlinux.org/packages/detach. However, detaching wasn't the issue.

I found the cause of this problem to be using a pyinstaller created gui program. It seems that pyinstaller makes a copy of the dynamic libraries it needs to use
which prevents system updates from breaking the gui program.

The running process sets up an environment that includes LD_LIBRARY_PATH; if a sub-process is using a different version of some .so then it may not work.

The solution is to unset LD_LIBRARY_PATH before execing the sub-process.
