[NicTanghe]

If annyone knows how to fix this and has spare time.

Followed build instructions on RHEL9.
installed Qt5 from qt.io's installer.
got stuck at the Configure step.

The Error I got after that one is about open Cl.
both ocl-icd and opencl-headers seem to be installed.

Next I`m getting these conserning GLU.
both libglvnd and libglvnd-devel are installed.

and i think the mesa ones dont make sence with nvidia drivers ?

Then I tried running CMAKE and ran into the following issues.

openssl-devel is installed

No module named '_tkinter'
fixed by

sudo dnf install tcl-devel tk-devel python3-tkinter

next.

sudo dnf install python-yaml sqlite-devel

then there ws an error about sys/sysctl.h that was missing wich is depricated. c #20

[la0011]

Should look something like this:

-DRV_DEPS_QT5_LOCATION=/opt/Qt/5.15.2/gcc_64/

[rogernelson]

There's also a rvcmds.sh file in the root of the repo that you can source that attempts to set up all the environment you need to build. Of course, not everyone's setup will be the same so if you use it please make sure the paths it sets are accurate -- you can override any of the paths it sets with environment variables.

[NicTanghe]

@la0011
THx that worked now I`m stuck at

CMake Error at /usr/local/share/cmake-3.25/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
  Could NOT find OpenCL (missing: OpenCL_LIBRARY OpenCL_INCLUDE_DIR)

  src/lib/ip/IPCore/CMakeLists.txt:255 (FIND_PACKAGE)

both ocl-icd and opencl-headers seem to be installed

@rogernelson
How whould i do that ?
I assume it's just

 source rvcmds.sh

[rogernelson]

Hi @NicTanghe. Yes, once you've done source rvcmds.sh and verified that all the paths are correct, you can do rvbootstrap to do the initial setup and build it or rvmk after the initial bootstrap to build it.

For the openCL error, have you installed the openCL headers? If you have a look at this section of the documentation, it gives a yum command that should install them (and other build dependencies).

[marcomeyerVFX]

I was stuck in the same place, got past it by additionally installing ocl-icd-devel (must have CRB repo enabled for that)
might be worth adding to the dependencies as well

[NicTanghe]

THx that fixed those.

Now its all the glu ones. (desc top)

[rogernelson]

Hi @NicTanghe Do you have the file /usr/lib64/libGLU.so on your system? If not, you can get it from the package mesa-libGLU

[NicTanghe]

but i dont use mesa drivers?
does that matter ?

also the mesa-libGLU package was already installed but

test -f /usr/lib64/libGLU.so || echo " doesnt exist."

returns doesn't exist

searching in nautilus
libGLU.so.1
does exist

[rogernelson]

If you already have libGLU, then great. Normally the setup is to link libLGU.so to libGLU.so.1 (which maybe be linked to something else). That is normally done at installation, but if not you could try just creating the symlink yourself.

sudo ln -s libGLU.so.1 /usr/lib64/libGLU.so

You'll also need the headers, do you have /usr/include/GL/glu.h installed on your system?

[NicTanghe]

I linked the files, Didn’t find the headers.
So I installed the devel package.
That seems to have done it.

Now CMake throws me errors about open ssl and i also can`t make heads or tails of them.

[marcomeyerVFX]

try installing nss

also, in case you haven't already I also had to install

meson zip python-unversioned-command perl-FindBin libXcomposite libXdamage libXrandr libXtst libXcursor

along the way.
