Having issue with hdtv installing. cern root installed from source code

[zak-dyer]

Hi there,

So I installed and created root from the source code and it opens and runs. import root also works on python. used the pip install hdtv command and when I try to run hdtv I get this:

Entirely lost as to how to fix this.
Any help would be greatly appreciated.

Hi!

I don't have a Mac so I can't test that, but I have these notes from Liam Gaffney from a few years ago:

* By default, dynamic libraries built on macOS have the .dylib extension, not .so:

    I fix this just by changing "lib%s.so" to "lib%s.dylib" in hdtv/rootext/__init__.py but there is probably a better way to do this to include both possibilities.


* By default, ROOT is not built with X11 support on macOS:

    I change all instances of #include "TGX11.h" to  #include "TVirtualX.h", which maintains support for X11 in any case (ROOT recommended method).
    - hdtv/rootext/display/View.hh
    - hdtv/rootext/display/[Painter.cc](http://painter.cc/)
    - hdtv/rootext/display/[XMarker.cc](http://xmarker.cc/)


* Locations for libraries etc installed with MacPorts is missing from CMakeLists:

    I added /opt/local/include and /opt/local/lib to the target_include_directories and target_link_directories, respectively.
    - hdtv/rootext/calibration/CMakeLists.txt
    - hdtv/rootext/display/CMakeLists.txt


* Calibration symbols missing when linking libdisplay.so/dylib:

    The library for calibration is not included when linking libdisplay.so for some reason. Full error shown below. You can see that it installs the calibration library in some .cache directory in my home folder, but then that is not found by cmake during the next build. Adding ${CMAKE_CURRENT_BINARY_DIR}/lib to the target_link_directories doesn't work, because that gives the path to where the libdisplay.so/dylib will be installed, which is different to libcalibration.so/dylib directory.

    I tried to include ${CMAKE_INSTALL_PREFIX}/lib instead, and this time I get no complaint about the library not existing, but the symbols are still missing. Therefore, I had to add calibration to the list of target_link_libraries, and then it works!

Not all of these points might be applicable anymore.

Please report back if you get things working or have a different problem - maybe we can develop a permanent fix for that.

using a virtual machine to simulate ubuntu and install everything other there seemed to work though had the same issues apart from the architecture.

Okay, it needs to link the calibration library (from hdtv/rootext/calibration) to the display, but can't. I'm quite rusty with CMake - maybe its enough to add calibration to target_link_libraries in hdtv/rootext/display/CMakeLists.txt .
