After installing v. 2540 for linux I get 'floating exception' and core dump. The installation went fine as far as I can tell. It's a laptop running Mandrake 10. So far, I've had no problem running chimera on it. any clue about what might have gone wrong ?
The last time I saw this error it was in ld.so, the Linux runtime linker/loader, and was due to trying to use Red Hat binaries on other Linux distributions. We "fixed" it by providing the backwards compatible .hash section. On 64-bit Linux builds, we provide both .hash and .gnu.hash sections, but that shouldn't matter to you since you should be using the 32-bit version of chimera. So the big change in chimera 1.2540 is the switch from Python 2.4 to 2.5. Please try running CHIMERA/bin/python2.5 and if it starts up successfully and gives you a >>> prompt, then type in: import sys sys.path.insert(0, 'CHIMERA/lib') import _chimera where CHIMERA is the path to the CHIMERA installation. And please send me email with your results. Thinking out load, maybe there is a related bug in Mandrake 10's ld.so? You should be able to verify that the bug is in ld.so by using valgrind (edit the bin/chimera shell script to run "valgrind python2.5 ..." instead of python2.5. And for future reference, please send me the exact version of Mandrake you're using, e.g., 10.0, 10.1, or 10.2. Greg Couch UCSF Computer Graphics Lab
