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...).
Removing references to the .la file did not do any good. vlc still
compiles, but segfault when run.
recompiling glib with autotools, vlc works (no need to recompile vlc)...
