Vicibox4.0 with Datacom E1 card

[ibra]

Hello All,

I am trying to install an E1 VB3030 PCIE Digivoice card.
-Asterisk version is 1.8.29.0-vici
-Libpri version is 1.4.15
-voicerlib-4.2.5.4
-dgvchannel-1.1.6

I am facing several problems during the installation of Voicerlib and DGVchannel.
The first problem is the missing of build directory in the RPM:

make: *** /lib/modules/3.11.10-21-default/build: No such file or directory

Has anyone been able to integrate a digivoice card with Vicibox?
Sorry if my question is incomplete, I am new in vicibox.

Thanks in advance,
Ibra
