net-im/tg_owt does not build on aarch64:

CMake Error at CMakeLists.txt:77 (add_library):
  Target "tg_owt" links to target "tg_owt::libusrsctp" but the target was not
  found.  Perhaps a find_package() call is missing for an IMPORTED target, or
  an ALIAS target is missing?

Comment 1 Henry Hu 2021-07-05 19:35:25 UTC
Well, I have no aarch64 machine (I may have some aarch64 SBCs, but they're too weak for telegram), so I can't fix this. Patches are welcome.

patch to files/patch-CMakeLists.txt to remove libusrsctp target for all the architectures

The proposed patch removes tg_owt::libusrsctp target for all the architectures, not only i386 and amd64.

It builds on aarch64 (poudriere builds telegram-desktop ok with net-im/tg_owt). Not tested on other ARMs.

I cannot assess whether the built library nor telegram-desktop work, due to (temporary?) lack of graphic support on my system.

As a side note, you might be willing to add to the port Makefile:
ONLY_FOR_ARCHS=        aarch64 amd64 arm armv7 i386
ONLY_FOR_ARCHS_REASON= upstream does not support other archs
Comment 3 pr 2021-07-07 23:05:07 UTC
I confirm telegram-desktop built on tg_owt works in aarch64.
Comment 4 pr 2021-07-14 07:00:46 UTC
Hi, this is solved by the proposed patch. Can it be committed?
Comment 5 Henry Hu 2021-07-15 03:16:02 UTC
Will take a look at the weekend. Need to test how this works on amd64.

(In reply to Henry Hu from comment #1)

Note: Anyone may test aarch64 (and other architectures) via poudriere build with the QEMU option, which can then create jails with any architecture. Very useful and helpful for QA

Wrong issue, apologies.
Comment 9 Mikael Urankar freebsd_committer freebsd_triage 2021-07-15 09:26:21 UTC
Why do we need to disable libusrsctp on FreeBSD? It's listed in LIB_DEPENDS and it's not used?
Comment 10 Henry Hu 2021-07-18 03:19:44 UTC
I should have noticed that this patch does not affect i386 and amd64. I didn't consider other platforms when I created the port. Tried to build amd64 and it still builds fine. I'm okay with this patch. Please commit it.

(In reply to Mikael Urankar from comment #9)
We're not disabling libusrsctp and it's still used. Notice that CMakeLists.txt is also patched to link with libusrsctp, with cmake_external.cmake also patched to provide the include and link directories.
The tg_owt carries its own version of libusrsctp, and has its own cmake file to build it. Since we already have it in the ports, I've patched it to use the ports version instead.

    net-im/tg_owt: Fix build on aarch64

    Don't build the bundled libusrsctp, use the one provided by
    net/libusrsctp like it's done on other arches.
