Hi.  
  
  
  
  
  
While trying to compile the ‘Iridescent’ tutorial, the  
  
  
  
  
  
 PVRUniSCo\_SGX53x FragShader.fsh FragShader.fsc -f  
  
  
  
  
  
command reports success while producing nothing.  
  
  
  
  
  
See below for the command I’m typing, the first part of the makefile output, and an strace of the misbehaving command - the strace makes it look like it’s not even trying to open the fsc file to write it.  
  
  
  
  
  
If I’m doing the wrong thing, trying to compile like this - where should I be looking for the README or INSTALL?  
  
  
  
  
  
Thanks.

So a partial solution:  
  
  
  
  
  
1. I found the root-level PDF file and the references in section 3 to Linux and lack of 64 bit support. Oh well. Maybe a 32bit chroot will work.  
  
  
  
  
  
2. It still seems funny for the utility to report success but produce nothing.

Hi,

1. We do not have full 64bit SDK yet. You can run some of utilities in 32 bit mode on you linux but, PVRVFRame (OGLESPC emulation) won't run that way. You can download PVRVFRame utility and inside you can find 64bit port of PVRVFrame (eg. PVRVFrame/OGLES2/Linux\_x86\_64) &nbsp;. Moreover in SDKPackage/Builds/OGLESX/LinuxX86/make\_platform.mak you should remove -m32 flag . Copy the libraries to&nbsp;&nbsp;  
SDKPackage/Builds/OGLESX/LinuxX86/Lib and then attempt to build the training course. We will have full support for 64bit Linux by the time of our next release.&nbsp;

2. As for PVRUniSCo , we no longer rely on binary shaders and compiler is to produce estimation of performance (it does not produce usc file anymore). So to conclude although it look confusing it fine. There is an error as result of missing usc file that is ignored and process carries on.

Regards,
