I have the same issue to run the compile_postprocess.sh.

[chm10]

I solved the compilation changing the above parts of compilation code and after installing rapidjson-dev.

sudo apt-get install rapidjson-dev

[chm10]

I tested but not worked yet. I almost sure the issue is from the environmet variables venv_hailo_rpi5_examples

python basic_pipelines/detection.py --help
Traceback (most recent call last):
  File "/home/user/hailo-rpi5-examples/basic_pipelines/detection.py", line 11, in <module>
    import hailo
ImportError: libgsthailometa.so.3: cannot open shared object file: No such file or directory

[chm10]

After reinstalling, worked.

sudo apt-get install --reinstall hailo-tappas-core-3.28.2

Install the compiled package.

$ cd build.release/
$ sudo ninja install

python basic_pipelines/detection.py --help

Hi did you install the apt hailo-all? these files should be installed by this install.

[jkllbn2563]

Yes, I have already run "sudo apt install hailo-all", but still hit the compile error

sudo apt install hailo-all Reading package lists... Done Building dependency tree... Done Reading state information... Done hailo-all is already the newest version (3.28.2+1). 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.

sudo apt-get install --reinstall hailo-tappas-core-3.28.2

can solve the compile issue. Thanks @chm10 !
