Hello, I am new to hedge and trying to install on my PC with Ubuntu 10.04 LTS, following the instructions in the wiki on http://wiki.tiker.net/Hedge/HowTo/InstallingFromGit/Ubuntu Everything seems to run OK until I do ./repotool start-over. I get errors when installing the islpy. It seems the problem is that it does not find gmp.h. I searched for and installed relevant packages using Synaptic Package Manager, but they did not install the gmp.h file and the problem persisted. Can anyone help me with info on where I find this file? regards Bjørnar Lund
