DV 1.4.1 released

[Luca Longinotti]

A new bug-fix release of DV is available.

RELEASE 1.4.1 CHANGELOG

DV GUI release 1.4.1 - 17.02.2021

- Added support for running on Apple M1 hardware with Homebrew.
- Added button to restart managed runtime if it crashes, for example
due to faulty user modules.
- Project list is alphabetically sorted (issue #157).
- Last selected project is correctly highlighted on GUI restart (issue
#158).
- Prevent busy loop from using too much resources in 'waiting for
connection' state (issue #156).



DV runtime release 1.4.1 - 17.02.2021

NEW FEATURES
- Build: added support for Apple M1 systems with Homebrew (issue #391).
- dv-runtime: added CLI option --console to disable logging of messages
to console (issue #390).
- CI: extended automated testing to ARM32, ARM64 and PPC64
architectures.

BUG FIXES
- Logging: do not log to console if started from GUI (managed runtime)
or started as a system service, correctly set log buffers on every
log-file opening (issue #390).
- Converter: fixed calculation of initial time offset for AEDAT 3
files, was not correctly using the timezone from the file, but the
host's one.

Hi Luca,

I have downloaded the new realease but I get some irregular messages that I didn't get before. I cross compile the dv-runtime software for a SoC based on ARM where a embedded Linux version called Petalinux is used. I have all dependencies in the root filesystem wehere the dv-runtime software will be cross compiled with and installed. When I configure the project using cmake, I get the following output:

The red messages are new in this compiling for this new realesed. I didn't get before and I don't know in what library that modules should be. I have tried to compile the project but I get the following error:

[ 13%] Linking CXX shared library libdvsdk.so

Do you know what I probably is missing??

Thanks in advance,

Hello, the libraries CMake doesn't find are for optional modules, if
they're not found, the modules in question are simply disabled.
- the various libavutil etc. are FFMPEG dependencies for the
video_output and livestream modules
- aravis is a dependency of the mvcamera module to support machine
vision cameras from other manufacturers

The compile error you see looks related to the 'fmt' library that we
depend on, it looks like only the static library (libfmt.a) is
available, and not the shared library (libfmt.so).
On Ubuntu, if you compile fmt on your own, you have to pass an
additional flag to fmt's CMake for this to work:

-DBUILD_SHARED_LIBS=ON

Hope this helps, have a great week!

Hi Luca,

That compile flag solved the compile error.

Thank you,
Antonio

Hello!

Can you give the instructions how to cross compile dv-runtime on Xilinx PetaLinux please?
