Subject: Problem with perf report --gtk
Date: Tue, 9 Sep 2025 12:33:12 +0200	[thread overview]
Message-ID: <aMACaOmneDrG8_pQ@gentoo.org> (raw)

Hi Arnaldo, Namhyung,

Since sometime we have a bug in Gentoo's bugzilla about perf report --gtk not
working¹: https://bugs.gentoo.org/937869

I know this feature is not used very much, but I thought I'd report in
any case. The problem is easily reproducible as shown below:


$ perf record -a -g -- sleep 1
[ perf record: Woken up 1 times to write data ]
[ perf record: Captured and wrote 1.818 MB perf.data (6648 samples) ]
$ LD_DEBUG=symbols perf report --gtk 2>&1 | grep '(fatal)'
    288067:	/usr/libexec/perf-core/libperf-gtk.so: error: symbol lookup error: undefined symbol: hashmap_find (fatal)
$ perf report --gtk
GTK browser requested but could not find libperf-gtk.so

I tried this with perf 6.16, but this bug seems to have been there since
at least 6.12.

Please let me know if it's better to file problems at https://bugzilla.kernel.org/.

Best regards,
-Guilherme
