• Product: Gentoo Linux

/var/tmp/portage/media-libs/gstreamer-1.18.4/work/gstreamer-1.18.4-abi_x86_64.amd64/tmp-introspect8106njp3/GstBase-1.0: symbol lookup error: /var/tmp/portage/media-libs/gstreamer-1.18.4/work/gstreamer-1.18.4-abi_x86_64.amd64/tmp-introspect8106njp3/GstBase-1.0: undefined symbol: gst_aggregator_start_time_selection_get_typePackage gstreamer-1.0 was not found in the pkg-config search path.
Perhaps you should add the directory containing `gstreamer-1.0.pc'
to the PKG_CONFIG_PATH environment variable
Package 'gstreamer-1.0', required by 'virtual:world', not found

uninstalling the package only resulted in that last 2 lines being added, so it's not a version mismatch. I also uninstalled plugins-bad which too seems to use the missing function-definition. I've masked off this version and it works.

Reproducible: Always

[Comment 1 Sam James 2021-09-20 23:35:34 UTC]

Please provide the full build.log and emerge --info, as the output here doesn't look right.

[Comment 2 piotr5 2021-09-21 08:20:04 UTC]

yes, sorry, I forgot a linebreak. not sure what my emerge --info would help, the verbose emerge just said

[ebuild  N     ] media-libs/gstreamer-1.18.4:1.0::gentoo  USE="caps introspection nls orc -test -unwind" ABI_X86="32 (64) (-x32)" 0 KiB

uname is

Linux-5.2.20-aufs-x86_64-AMD_A10-7890K_Radeon_R7,_12_Compute_Cores_4C+8G-with-glibc2.33

I searched and the missing symbol is not found in /usr/include, the compilation-output contains the symbol in 

work/gstreamer-1.18.4-abi_x86_64.amd64/libs/gst/base/libgstbase-1.0.so.0.1804.0

and it's in the sources 
work/gstreamer-1.18.4/libs/gst/base/gstaggregator.h
work/gstreamer-1.18.4/libs/gst/base/gstaggregator.c

in the log there's warnings for deprecated g_memdup in
libs/gst/base/libgstbase-1.0.so.0.1804.0.p/gstbitwriter.c.o

libs/gst/base/libgstbase-1.0.so.0.1804.0.p/gstbytereader.c.o

and finally the actual error is in executing the command starting with
[171/203] /usr/bin/g-ir-scanner --no-libtool --namespace=GstBase --nsversion=1.0 --warn-all --output libs/gst/base/GstBase-1.0.gir

i.e. the actual compilation works fine, the post-compilation things are allowed to assume that maybe you already did do the install hence the problem with pkg-config followed by
Command '['/var/tmp/portage/media-libs/gstreamer-1.18.4/work/gstreamer-1.18.4-abi_x86_64.amd64/tmp-introspect8106njp3/GstBase-1.0', '--introspect-dump=/var/tmp/portage/media-libs/gstreamer-1.18.4/work/gstreamer-1.18.4-abi_x86_64.amd64/tmp-introspect8106njp3/functions.txt,/var/tmp/portage/media-libs/gstreamer-1.18.4/work/gstreamer-1.18.4-abi_x86_64.amd64/tmp-introspect8106njp3/dump.xml']' returned non-zero exit status 127.

thinking it possible the error was caused by g-ir-scanner or rather dev-libs/gobject-introspection being last compiled before switching profile and thereby caused by some /lib vs /lib64 mess, I fixed that situation but still got the same error. or rather since I reinstalled the old version I get the thing without pkg-config problems:

guess in future I'll need to compile media-libs/gstreamer with
USE=-introspection
before recompiling it normally?

[Comment 3 Alex 2021-12-10 16:43:12 UTC]

I want to confirm the bug, and quick fix, the build with
USE=-introspection emerge -1av --nodeps media-libs/gstreamer 
makes next normal build successful.
Both are compiled with FEATURES="distcc"

[Comment 4 Kyle Elbert 2022-03-24 08:59:42 UTC]

Created attachment 767691 [details]
gstreamer 1.20.1 arm64 build.log

still hitting this with 1.20.1 on arm64. Just as the last comment, its g-ir failing

[Comment 5 Sam James 2022-03-26 22:40:36 UTC]

Has anyone actually hit this without distcc?

[Comment 6 microcai 2022-04-10 09:58:01 UTC]

(In reply to Sam James from comment #5)
> Has anyone actually hit this without distcc?

hit, but with 1.20.1 version

linker error persist with every possible compiler/linker combinations.

after disable introspection, error gone.

so g-ir-scanner is really the faulty part.
