Re: [Openexr-user] 'make check' on Intel Mac

[Paul Schneider]

Hi, Jay,

it looks like you built the EXR libraries as intel-only, but you are  
building the testing code universal (intel & ppc).  The PPC build is  
failing because you don't have PPC versions of the EXR libraries.

My guess is that you have a PowerPC version of Matlab.  OS X will run  
Matlab transparently for you using emulation software called Rosetta.   
But the PowerPC Matlab will need PowerPC EXR libraries to read and  
write EXR files.  You can confirm this by selecting the Matlab  
application in the Finder and choosing "Get Info" - it will say  
"Application (PowerPC)" or "Application (Universal)".

You can fix this by rebuilding your EXR libraries as Universal  
libraries, like this:

%cd OpenEXR
%make distclean
%./configure --enable-osx-universal-binaries --disable-dependency- 
tracking
%make
%sudo make install

(repeat for IlmBase)

This will build the libraries for both Intel and PPC, and then both  
Intel and PPC applications can link to them.

Good luck!
- Paul
