Root and cygwin --> Problem with the new X server

ROOT
1

Hello,
I guess I already know the problem but I’d like to be sure. Few days ago I installed a new package in cygwin and because of that also the Xserver was upgraded. Now I have Cygwin/X 1.5.3 and I found out a lot of things changed (for example to start the normal Xserver I’m not using anymore startx but startxwin.bat).

After that upgrade, root doesn’t work anymore properly:

$ root

Now I’m going to download the source and try to recompile it (and see what happen…) Anyone out there with the same problem?

I’ll keep you informed

Update:
I recompiled root from scratch and tried again but I have now another error

I installed openGL but it’s not enough…

Last update:
the error is still there but it seems is not arming and I’m able to run my macros…

Hi,

you’ll probably have to build ROOT from sources. The ROOT binaries expected the now old, incompatible version of the libraries.

Cheers, Axel.

This is actually what I did… (see my secondo post)

and after the new build from source I got the new error:

root [0] TCanvas *singlePlot2 = new TCanvas("singlePlot2","")
Error in <TUnixSystem::DynamicPathName>: RGL[.so | .sl | .dl | .a | .dll] does not exist in .:/cygdrive/c/Programmi/root_v5.20.00/lib::/cygdrive/c/Programmi/root_v5.20.00/lib:/cygdrive/c/Programmi/root_v5.20.00/cint/cint/stl
root [1]

Just to let you know…
Ciao

Was there any error during the build?
