Can anyone give me some pointers on how to get out of this  :---

I have glibc and glibc-dev installed (or devel )

[elir71]

the above was solved by compilitng as privileged user.

Now have a problem with  sound

[forum_admin]

Hi, do you have libsndfile and portaudio installed? What is the specific problem?
Thanks

[elir71]

sudo dnf install cmake portaudio-devel g++ freeglut-devel irrlicht libXxf86vm-devel libsndfile1-dev libXcursor-devel

# goto the bin directory in the source tree

cmake ../src/
make

[elir71]

For fedora 36 then use the following, note its now libsndfile-devel

sudo dnf install cmake portaudio-devel g++ freeglut-devel irrlicht libXxf86vm-devel libsndfile-devel libXcursor-devel

# goto the bin directory in the source tree

cmake ../src/
make

I've a three screen system each running an upto date fedora 36 and latest bridgecommand compiled from source

the middle screen (master station) feed the port and starboard stations as secondary displays

All hardware is identical, swap identical

for some reaon the starboard display lags far behind the other two

any ideas what i should be looking at

[elir71]

I looked at the BIOS settings and there was no hardware acceleration.  Much improved since enabling that
