What Linux distro do you have?

My distro is centos 8.

I build OpenModelica from git repo. I clone recursively OpenModelica and all its dependencies from github. My build works well.

But when I analyze the makefile for the component "OMEditLIB", the makefile contains the flag "-DWITHOUT_OSG".  I would like to know what is the configure option to change this flag .

Many thanks

As far as I know we do have WITH_OSG on by default so it seems to be some configure issue when detecting how to use osg + qt.
Search in OMEdit/config.log for OSG and see where it fails to use OSG. There should be some compilation tries with OSG and one of them is failing.

Start looking here: https://github.com/OpenModelica/OpenMod … ure.ac#L70
You can also look in OMEdit/config.log to see what is happening there.

HI,

I find an issue in https://github.com/OpenModelica/OpenMod … nfigure.ac file.

On my computer, OpenSceneGraph is installed in a non standard path.

So, my script to build is :

export CPPFLAGS="-I/path/to/OSG/include"
export LDFLAGS="-L/path/to/OSG//lib64"

CONFIGURE_OPTIONS="--prefix=/path/to/my/prefix"
       
CONFIGURE_OPTIONS="${CONFIGURE_OPTIONS} CC=/path/to/my C compiler"
CONFIGURE_OPTIONS="${CONFIGURE_OPTIONS} CXX=/path/to/my C++ compiler"

./configure ${CONFIGURE_OPTIONS}

I see in the config.log file that "ac_cv_env_CPPFLAGS_value" and "ac_cv_env_LDFLAGS_value" variables are well initialized but these variables are not used to generate makefile.

I continue to investigate.
