Crash on ArchLinux

[bda65hp]

Hi all,
After manual compilation (the binary version do not work because there's no libbfd-system here), Ctrlr launch but crash each time i try to open or create a new panel.
With 5.6.0, master and kiosk.
If i compile the Debug version, it work but without any MIDI in/out.

Ctrlr crash at: 16 Jun 2021 11:42:26 Stack trace: ./Ctrlr(+0x614dba) [0x55bf51ededba] ./Ctrlr(+0x553735) [0x55bf51e1d735] ./Ctrlr(+0x60309d) [0x55bf51ecd09d] /usr/lib/libpthread.so.0(+0x13870) [0x7f3c99679870] ./Ctrlr(+0x8bb626) [0x55bf52185626] ./Ctrlr(+0x8bb9d4) [0x55bf521859d4] ./Ctrlr(+0x9f8d64) [0x55bf522c2d64] ./Ctrlr(+0xa0147f) [0x55bf522cb47f] ./Ctrlr(+0xa01fae) [0x55bf522cbfae] ./Ctrlr(+0x8f7ee1) [0x55bf521c1ee1] ./Ctrlr(+0x8e46d2) [0x55bf521ae6d2] ./Ctrlr(+0x562bd4) [0x55bf51e2cbd4] ./Ctrlr(+0x69c24a) [0x55bf51f6624a] ./Ctrlr(+0x69b193) [0x55bf51f65193] ./Ctrlr(+0x69b367) [0x55bf51f65367] ./Ctrlr(+0x2a729c) [0x55bf51b7129c] /usr/lib/libc.so.6(__libc_start_main+0xd5) [0x7f3c98fc5b25] ./Ctrlr(+0x55345e) [0x55bf51e1d45e]

I can send the compilation output if needed.

[keinstein]

Can you try https://github.com/keinstein/ctrlr/tree/lua5.2, please? I's for Debian, but maybe it helps for you, too.

See also #294

Edit: I only updated LinuxMakefile so far. And libusb is still disabled.

[keinstein]

It could be a duplicate of #168 In that case the backtrace is useless.

[keinstein]

And it is probably a duplicate of #294 .

[bda65hp]

@keinstein Same problem with your branch on Arch.

I don't know if it's related, but i always need to rewrite the makefile with Projucer. If not, i've got thi error:
Makefile:336: *** target pattern contains no '%'. Stop.

[keinstein]

This problem is well-known. That's why I just ignore the vst builds and build just the Standalone version as I described in #294.

[bda65hp]

Yes, but it crash in Standalone only version too.

[keinstein]

check out the branch lua5.2, please and create a backtrace as discussed in #294, please.

[bda65hp]

Debug version do not crash but there's no MIDI in/out.

It seems as you don't use the build system from the lua5.2-branch.
Please use the system provided lua, luabind, boost and lua-bitop (see also https://bbs.archlinux.org/viewtopic.php?id=197531).

And don't use the included luausb library (libusb folder). It is known to crash my system and its too old to be considered.

[bda65hp]

There no more lua-bitop in arch repos.
It's too difficult for me to use Ctrlr on Arch actually.
Provided lua version is 5.4.
I don't know which build system i use. I do make -f pchbuild.mk CONFIG=Release Standalone

Thanks very much for your help.

[keinstein]

There no more lua-bitop in arch repos.

Please, take a look at https://archlinux.org/packages/?sort=&q=lua+bitop&maintainer=&flagged=
It seems that you have to enable the Community repository.

It's too difficult for me to use Ctrlr on Arch actually.

Yes, you can help to make it better. I can't do the work for you as I'm working with Debian.

Provided lua version is 5.4.

That's not supported, yet. I chose 5.2 because it fits together on Debian. 5.4 introduces integers which would be a great improvement for Ctrlr, even for existing code. But luabind and possibly other code must be updated in order to support everything from lua5.4.

BTW.: Arch Linux supports lua 5.2 (Extra repository) https://archlinux.org/packages/?sort=&q=lua&maintainer=&flagged=

I don't know which build system i use. I do make -f pchbuild.mk CONFIG=Release Standalone

This is ok. Which brach did you checkout? You need the lua5.2 branch.

Thanks very much for your help.

I help as much as I can. But I can't support the outdated lua libraries that come with the Ctrlr source code.

[bda65hp]

Sorry, my bad. lua52-bitop is in the repos. But there's no luabind. I've compiled one for lua5.2 but there's no object_fwd.h (same source as in Debian stable repo):
