[Chimera-users] Chimera on Linux PPC

Hi Justin,

  We do not currently build Chimera for Linux with PowerPC processors.  
Chimera includes more than 30 third-party libraries which we build 
automatically on each supported platform (Windows, Mac, Linux...).  
Compiling all those libraries is the real problem.  Many of those 
libraries require special patches to build on all our platforms 
(Windows, Linux, Mac).  It would likely take weeks of work for Linux PPC 
for someone very experienced in compiling open source packages from 
source code.  We do not have the resources to do that for such an 
obscure platform.  The next platform we will likely support is Mac 
64-bit (Intel) sometime in the next year, after that 64-bit Windows.

  The latest Chimera can be compiled without the proprietary molecular 
surface code.  We don't have that latest source code on the web site, 
but if you manage to build all the third-party packages (called 
"foreign" packages on our source code download page) I'd put the latest 
source code on the web and tell you how to disable the molecular surface
