Overlay elements broken #7

Closed coldfix closed 7 years ago

coldfix commented 7 years ago

Originally reported by @DavidSagan:

When there is a controller element (group, overlay, girder) in the lattice then madqt will fail reading in the lattice since these elements do not have defined a length. The error message I get is:

libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

An example lattice is:

parameter[particle] = #12C+6
parameter[geometry] = open

beginning[e_tot]    = 400e+9

beginning[beta_a]   = 44
beginning[beta_b]   = 4
beginning[alpha_a]  = -7
beginning[alpha_b]  = -1

bb: sbend, l = 2, angle = 1
oo: overlay = {bb}, g_err

seq: line = (bb)
