Hi
I'm trying to resurrect IDL on a ubuntu box and am struggling with a
basic tv (or tvrd) seg fault.
I feel like an idiot asking this, but I can't perform a simple tv or
tvrd() without a segmentation fault.
The simple thing I'm doing is:
buf = bindgen(256,256)
device,DECOMP=0
window,/FREE,XS=256,YS=256
device,GET_DECOMPOSED=decomp
print,'!d.n_colors=',!d.n_colors,', DECOMPOSED=',decomp
help,/device
tv,buf
What I get is:
IDL Version 6.3 (linux x86 m32). (c) 2006, Research Systems, Inc.
Installation number: 2330-1.
Licensed for use by: PET IMAGING SERVICE, VAMC, MINNEAPOLIS

IDL> buf = bindgen(256,256)
IDL> device,DECOMP=0
% Unsupported X Windows visual (class: PseudoColor, depth: 8).
Substituting default (class: TrueColor, Depth: 24).

(the pseudo-color msg comes from my .idlrc file which contains:
!QUIET = 1
!ORDER = 0
print,!quiet,!order,FORMAT='("Initial setup: quiet=",i1,",
order=",i1)'
; this will default to truecolor if pseudocolor is not supported
