- We have recently received a Reality Engine. However, I have seen
- an incompatibility with other SGI machines regarding colormaps. For
- example, I have a very short program using *only* X that allocates
- (XAllocColorCells) colors, then sets colors (XStoreColor then XSync).
-
- In one case I allocate only 2 colors. The XAllocColorCells succeeds
- but the XStoreColor fails (BadAccess). In another case I allocate
- 32 colors, then allocate 256 more and set the 256 colors that I allocated
- last. No errors, but no color changes either (using the colormap tool).
-
- In all cases the default display and colormap (DefaultColormap) were
- referenced (to avoid flashing between applications).
-
- Any suggestions or ideas? Please respond by email. Thanks much.
