If doing your own builds -- some changes / potential requirements
by Phyllis Smith 25 Feb '19

25 Feb '19

Because GG is preparing early for the end of the month builds, he has had to modify the blds directory scripts to accommodate the various Operating Systems and to get the best solution for the widest variations of usage. So if doing your own builds, you may have to do some minor adjustments or more library installs and re-run bld_prepare.sh. For example with the inclusion of AV1, WebP, and Shuttle USB Direct, some new libraries have to be installed. Also, he has changed Shuttle inclusion to "yes", thus requiring libusb-1.0-0 dev be installed unless you revert to Shuttle inclusion of "no". Some new libraries that *might *be needed: libwebp-1.0.2 - for WebP libtoolize - for WebP libaom-v1.0.0 - for AV1 libusb-1.0-0 dev - for Shuttle Pro to ensure K14/K15 function properly (and it is just better too). I hope this clarifies things. I should have relayed this information earlier. If any problems, let us know so we can fix them. gg/pys

libzmpeg3 on non-x86/non-MMX arches, also little bit about CPU detection in autoconf.
by Andrew Randrianasulu 25 Feb '19

Hello again. Recompiling Cinelerra-GG even partially on emulated ppc64le machine is SLOW process, so sorry if I fire those ideas faster than I can test them properly. I was looking at libzmpeg3, because without it a lot of functionality (dvb, v4l2) simply not there, and _may be_ found reason why it was so insisting on MMX assembler: https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… 121 $(OBJS): 122 $(CC) -c `cat $(OBJDIR)/c_flags` $(subst $(OBJDIR)/,, $*.C) -o $*.o 123 $(ASMOBJS): 124 $(CC) -c `cat $(OBJDIR)/c_flags` $(subst $(OBJDIR)/,, $*.S) -o $*.o 125 $(NASMOBJS): 126 $(NASM) -f elf $(subst $(OBJDIR)/,, $*.s) -o $*.o So, I'll try with libzmpeg3 enabled and those four lines (123, 124, 125, 126) removed ... More stackoverflow! https://stackoverflow.com/questions/23379805/determining-architecture-in-ma… ---------copy---------- 1 Answer active oldest votes 4 Selecting the CPU and OS is better handled in configure.ac, which has AC_CANONICAL_HOST which parses the output from uname and puts it in a standard format: configure.ac ... AC_CANONICAL_HOST WRAPPER_CPPFLAGS="" AS_CASE([$host_os], [linux*], [ WRAPPER_CPPFLAGS="$WRAPPER_CPPFLAGS -DLINUX" AS_CASE([$host_cpu], [x86_64], [ WRAPPER_CPPFLAGS="$WRAPPER_CPPFLAGS -DAMD64 -I../../../external/xerces-c-3.1.1-x86_64-linux-gcc-3.4/include" ], [i?86], [ WRAPPER_CPPFLAGS="$WRAPPER_CPPFLAGS -I../../../external/xerces-c-3.1.1-x86-linux-gcc-3.4/include" ]) ], [darwin*], [ WRAPPER_CPPFLAGS="$WRAPPER_CPPFLAGS -DOSX" AS_CASE([$host_cpu], [i?86], [ WRAPPER_CPPFLAGS="$WRAPPER_CPPFLAGS -I../../../external/xerces-c-3.1.1-x86-macosx-gcc-3.4/include" ]) ]) AC_SUBST([WRAPPER_CPPFLAGS]) ------------- well, in our case configure.ac needs some MMX-outing for non-x86-machines AND thirdparty-libs=ON. Alpine linux additionally need -lexecinfo for backtrace symbols, and -lintl for internationalization.

incomplete ppc64le diff
by Andrew Randrianasulu 24 Feb '19

24 Feb '19

I basically force-disabled fileac3, added define for ppc64le arch in guicast/Makefile, killed few lines in guicast/bcsignals.C Note I alos force-removed line about "utils/mmxsse/.libs/libmmxsse.a" from global_config after configure was finished. Now, it still fails to link main 'cin' executable, but some of those errors come from dvb (will force-disable it too), and some errors about internationalization - probably musl issue

Found from where BOOTSTRAP variable comes ...
by Andrew Randrianasulu 24 Feb '19

24 Feb '19

I'm stupid, it was defined in https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… ifeq ($(OBJDIR), i686) 5 BOOTSTRAPFLAGS := -DBOOTSTRAP="\"objcopy -B i386 -I binary -O elf32-i386\"" 6 endif 7 8 ifeq ($(OBJDIR), x86_64) 9 BOOTSTRAPFLAGS := -DBOOTSTRAP="\"objcopy -B i386 -I binary -O elf64-x86-64\"" 10 endif 11 ifeq ($(OBJDIR), amd64) 12 BOOTSTRAPFLAGS := -DBOOTSTRAP="\"objcopy -B i386 -I binary -O elf64-x86-64\"" 13 endif --- so, i guess for ppc64 I need to add similar case with objcopy, just about ppc

More adventures in (emulated) ppc64le land
by Andrew Randrianasulu 24 Feb '19

24 Feb '19

Sorry for a bit of "dev" spam, just trying to be useful for some (Daniel). After if 0'ing most of code in https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… handle_dump() (so it will compile into something even on ppc) and shuting up "BOOTSTRAP undeclared" in https://git.cinelerra-gg.org/git/?p=goodguy/cinelerra.git;a=blob;f=cinelerr… see line 197, sprintf(system_command, "%s %s %s", BOOTSTRAP, temp_path, out_path); my system somewhat dislikes it. I got into futher trouble :/ fileac3 uses filempeg and filempeg gives incomplete class FileMPEG if you try to compile Cin-gg with --with-commercials=no, with-libzmpeg3=no :/

signal handling on ppc64le
by Andrew Randrianasulu 24 Feb '19

24 Feb '19

... I'm not a porter, yet it seems i found something relevant: https://stackoverflow.com/questions/48526785/extract-program-counter-instru… --------------- @Radu The numbered slots in the gp_regs array are just the numbered general purpose registers, r0 .. r31, with the functions defined by the ABI (e.g. r1 is the stack pointer and r2 is the TOC pointer). Of the named fields in the struct, ctr, link, xer, ccr, softe, mq, dar, and dsisr correspond to named registers in the architecture manual, and orig_gpr3, trap, and result are labeled with their function. That leaves only nip to be the PC. – zwol Jan 31 '18 at 12:21 --------------- https://elixir.bootlin.com/linux/latest/source/arch/powerpc/include/uapi/as… https://sourceforge.net/p/predef/wiki/Architectures/ so, I just defined IP = nip in bcsignals.C in if __powerpc64__ ifdef . now I forgot Cinelerra-GG requires python 3, time to isntall python3 ....

Error in db/ on Alpine linux (musl-libc)

24 Feb '19

Guess i'm tried to bite off too big piece of pie for now ... g++ -c -o ppc64le/tdb.o tdb.C tdb.C: In member function 'int Db::icommit(int)': tdb.C:4606:54: error: 'qsort_r' was not declared in this scope qsort_r(pages, npages, sizeof(*pages), ioCmpr, this); ^ tdb.C: In member function 'int Db::load()': tdb.C:6218:54: error: 'qsort_r' was not declared in this scope qsort_r(pages, npages, sizeof(*pages), ioCmpr, this); ^ make: *** [Makefile:35: ppc64le/tdb.o] Error 1 it seems qsort_r was not implemented in musl libc at least in 2017: https://github.com/elogind/elogind/issues/83 - see comment "maxice8 commented Oct 18, 2018" - "Musl upstream has refused to merge qsort_r since there are 2 competing implementations claiming the same name from GNU and from FreeBSD i guess in the meantime the GNU qsort_r can be provided on musl_missing ?" In c programs this can be workarounded, not sure about c++ http://lists.openembedded.org/pipermail/openembedded-core/2014-March/091307… https://github.com/Lupus/ccl/blob/master/qsort_r.c But in meantime I'll try to disable zmpeg3 and tdb, and signal handling (if possible) in hope it will make Cinelerra-GG buildable.

Build error on (emulated) ppc64le
by Andrew Randrianasulu 23 Feb '19

23 Feb '19

Unfortunately, after building all thirdparty libs Cin-GG failed to build itself. It seems some x86 assembler usage not guarded?

[wild idea] Phoronix benchmarking
by Andrew Randrianasulu 23 Feb '19

23 Feb '19

Hello, all! I was thinking about Cinelerra's batch mode, and statistics it prints at user session end. May be if GG adds printing fps after batch file (with provided project xml, specific preferences, and media files) processing - it will be useful addition to PTS - Phoronix Test Suite. https://www.phoronix.com/scan.php?page=home I think I can ask Michael what he thinks about this idea, and what size of media test files acceptable for inclusion....

Two more compile errors on non-x86

Sorry, it seems right now Cin-GG quite tied to glibc/x86 (mmx) I tried to build files in guicast and plugins, and got two more errors: make -C 1080to480 make[1]: Entering directory '/root/src/cinelerra/cinelerra-5.1/plugins/1080to480' g++ -shared -o /root/src/cinelerra/cinelerra-5.1/plugins/../bin/plugins/video/1080to480.plugin ppc64le/1080to480.o `cat ppc64le/l_flags` g++: error: /root/src/cinelerra/cinelerra-5.1/plugins/../thirdparty/mjpegtools-2.1.0/utils/mmxsse/.libs/libmmxsse.a: No such file or directory make[1]: *** [../../plugin_config:21: /root/src/cinelerra/cinelerra-5.1/plugins/../bin/plugins/video/1080to480.plugin] Error 1 make[1]: Leaving directory '/root/src/cinelerra/cinelerra-5.1/plugins/1080to480' make: *** [Makefile:188: 1080to480] Error 2 -------------------- g++ `cat ppc64le/c_flags` -DMSGQUAL=bcsignals -c bcsignals.C -o ppc64le/bcsignals.o bcsignals.C:393:2: error: #error gotta have IP #error gotta have IP ^~~~~ bcsignals.C: In function 'void handle_dump(int, siginfo_t*, void*)': bcsignals.C:410:30: error: 'struct sigcontext' has no member named 'IP' uint8_t *ip = (uint8_t *)c->IP; ^~ bcsignals.C:424:14: error: 'struct sigcontext' has no member named 'IP' (void*)c->IP, pid, tid); ^~ At global scope: cc1plus: warning: unrecognized command line option '-Wno-stringop-truncation' cc1plus: warning: unrecognized command line option '-Wno-format-overflow' cc1plus: warning: unrecognized command line option '-Wno-format-truncation' cc1plus: warning: unrecognized command line option '-Wno-stringop-overflow' cc1plus: warning: unrecognized command line option '-Wno-unknown-warning' make: *** [Makefile:123: ppc64le/bcsignals.o] Error 1 second one probably linked to Alpine's use of musl C library ..still, first one directly points at mmx/sse library from mjpegtools.
