Failed to build Veyon form source code (Could NOT find LibVNCClient)
-
My operating system is Linux Mint 19.3 32 bit. I try to build veyon from source code, following by guide on veyon's github:
https://github.com/veyon/veyonBut unsuccessfully, cmake shows this output:

I recommend downloading one of the official source code archives since they include the full source code including 3rdparty libraries. If you want to build Veyon from Git repo, make sure to initialize and checkout all submodules by running
git submodule update --initinside the source tree. Consider switching to the4.5branch before if you want to build the latest stable version. -
@tobydox
I have the same issue as the thread starter.I cloned the repo and changed into
veyonsource directory. Then I checked out v4.5.3:git checkout v4.5.3Then I updated all submodules
git submodule update --init --recursiveand then followed the installation instruction in the README.md:
mkdir build cd build/ cmake ..And at this point cmake fails with the log pasted at the end of this post.
Why v4.5.3? Because it is the latest package on Raspberry Pi OS and on my Laptop I want to use the same version.
I already tried with latest master (9e648b18e973f33b547c6e3d19b5d15b43381656). I could compile and install this version successfully on my laptop. And I could connect successfully with my other laptop running the same version. But I could not connect to the Raspberry Pi running version 4.5.3. So that is why I want to install this older version on my laptop.
And I also tried as you suggested to download the source tarball and build that, but the result is the same.

FYI:
I could successfully build and install the current master on Raspberry Pi OS. And now with the same version on both machines (Raspberry Pi as Student, Laptop as Teacher), I successfully connected to the student's machine.
The drawback is that I cannot make use of Raspberry Pi OS's package management. Instead I will have to compile on all student machines or find another way to quickly install the binaries on the other Raspberry Pis.

@lmoellendorf Can you try passing
-DWITH_PCH=OFFto CMake? Which version of CMake are you using?
