Hi,
since GCC 10 introduction to Fedora, mozjs68[0] package started to fail[1]
to compile on armv7.
Apparently, some data structures changed their size:
/builddir/build/BUILD/firefox-68.5.0/js/src/vm/Shape.h:807:58:
error:
static assertion failed: Things inheriting from gc::Cell must have a size
that's a multiple of gc::CellAlignBytes
/builddir/build/BUILD/firefox-68.5.0/js/src/vm/JSScript.h:3408:59: error:
static assertion failed: Size of LazyScript must be an integral multiple of
js::gc::CellAlignBytes
3408 | static_assert(sizeof(LazyScript) % js::gc::CellAlignBytes == 0,
Nuking all those static_assert checks [2] resulted in unusable binary, so
that's unfortunately not a way forward. Bug has been reported to mozilla
bugzilla:
https://bugzilla.mozilla.org/show_bug.cgi?id=1612797
The last successful build was made in GCC 9 side tag.
I am currently busy with other more pressing issues, so I'll try to add
more meaningful information to this thread later, if needed.
However, if anybody could take a look at it, I'll be grateful and send tons
of virtual cookies!
Thanks a lot
