OBS 32 Launch error with LibAjantV2

[BenMitnicK]

Hi,
I successfully compiled LibAjantV2 and installed the library for compiling OBS 32
Compiling OBS goes very well with these warnings but it compiles

-- aja: Using new libajantv2 library
CMake Warning (dev) at cmake/finders/FindLibAJANTV2.cmake:100 (message):
  Failed to find LibAJANTV2 version.
Call Stack (most recent call first):
  plugins/aja/CMakeLists.txt:10 (find_package)
This warning is for project developers.  Use -Wno-dev to suppress it.

-- Found LibAJANTV2: /usr/local/lib/libajantv2.a (found version "0.0.0")

Once OBS is launched I have this symbol error that I can't resolve

info: ---------------------------------

I posted on the forum and the OBS discord but no response
So I don't know if it comes from OBS or LibAjantV2
Especially solve this problem
Thanks for your reply :)

Pre-build libajantv2 and make sure the includes and lib are placed into the proper search path(s) specified in OBS's cmake/finders/FindLibAJANTV2.cmake file.

Also, the last version of libajantv2 that was officially checked and built with OBS, was libajantv2 version 17.0.1 from (this hash. More recent versions may work but I haven't yet tested them. I'm hoping to allocate some time in the near future to check OBS with more recent libajantv2 releases.

Hi thanks for your reply,
Yes the includes and lib are placed into the proper search path(s) specified in OBS's cmake/finders/FindLibAJANTV2.cmake file.

I tested 17.5 and 17.1.3 are the same problem
I tested 17.1.0 and 17.0.1 the compilations have errors and they are the same errors in both versions HERE
I haven't looked at the problem yet, it was late.

I will continue to try to find the solution ... Thanks for your help :)

PS: I use Debian Trixie

I wonder if the libajantv2 version number is being overridden in your build. The message you're seeing is a bit odd:
-- Found LibAJANTV2: /usr/local/lib/libajantv2.a (found version "0.0.0")

According to the logs, it seems to be finding a libajantv2.a file with a version of 0.0.0. If libajantv2 itself is having it version number overridden or is otherwise unset (it should default to the value in VERSION.txt in libajantv2), then certain methods that OBS uses (such as CNTV2DeviceScanner::GetDeviceInfoList) might be getting ifdef'd out.

I'll try to set aside some time to try a build myself.
