Andrew, some problems/feedback and I have attached the thirdparty/Makefile based on current GIT + 0004-TEST (some manual editing) so you can see
What are all of these changes with "autoreconf" for? This builds, BUT I have no way to test them:
0002-Test-try-to-fix-autoreconf-in-libav1394.patch
0004-TEST-autoreconf-for-thirdparty-libs-for-new-arches.patch
The above patch fails so far with:
make[2]: *** [Makefile:353: /tmp/cin5/cinelerra-5.1/thirdparty/../thirdparty/build/libdv.configure] Error2
And before that had to fix line:
+ libiec61883.cflags?="$(call inc_path,libraw1394)"
to remove the blank space between the "+" and "libiec..."
You already removed this patch which fails to build and I do not see any replacement so skipping: 0003-fix-dav1d-0.5.1-patch-non-x86-incompatible-atm.patch
make[2]: *** [Makefile:341: /tmp/cin5/cinelerra-5.1/thirdparty/../thirdparty/build/dav1d.built] Error 2
