Hi, building vlc with the current book instructions, I get:

Using gdb, it seems to occur in a glib function
(g_hash_table_lookup_node).
Has anybody seen this?
glib built with meson still has issues. I suggest sticking to
autotools
build whenever it's available, no matter if the package has meson
support.
Have you found any issues with the glib meson build currently in
-dev?
lol, that's what this thread seems to imply:
- glib2 built with meson: segfault during build of vlc
- glib2 rebuilt with autotools: no segfault during build of vlc.
Forget about vlc itself segfaulting after rebuild: it's another
story (and
actually, the primary reason why I had to rebuild vlc :), moving to
newer
libva.
Interesting. Other than a few thousand warnings for unknown pragma,
vlc
builds fine for me. On this particular system I'm still using the
older
libva though. I have no problem yet running vlc at least until getting
the startup window.
I'll try updating libva and rebuilding vlc.
Build of libva-2.0.0 followed by vlc-2.2.6 produced no errors for
me. I was able to run vlc, but I only tested to the default window.
Is there something I can do to trigger the problem?
I do not know exactly. Note that it is the segfault during the build
of vlc, which was related to glib. The other one I got (and which is
now fixed) was related to ffmpeg not being recompiled _after_ libva.
Actually, here is my initial build order (in the order new versions
appeared in the book):
ffmpeg-3.4
libva-2.0
glib-2.54.2 (using meson, but keeping the libglib-2.0.la file).
Then I noticed vlc had sound but no video. So I decided to rebuild
vlc. I got this segfault during build (running ./vlc_cache_gen), and
gdb showed it was in a glib function.
I rebuilt glib-2.54.2 with autotools, then vlc, which went to
completion. But I got the segfault in vlc (before any interface
appeared).
I rebuilt ffmpeg. Now vlc runs (the big bug bunny movie).
What I can do now is to rebuild glib with meson (keeping first
libglib-2.0.la, then using the instructions Bruce provided in his
other mail). Then try to rebuild vlc.
Here is the tonight (European time) interesting(!) experiment: I've
rebuilt glib2 by the book, but keeping the old .la file. then I've
rebuilt vlc, and that went to completion, but when I started vlc, I got
immediately a segfault. And guess what, gdb tells it is in a glib2
function (g_hash_table_lookup again)... I have rebuilt ffmpeg, but no
change. I have not tried to recompile libva...
Let us try now by removing the .la file, and removing references to it
(I'll archive them first, just in case...).
