Compilation Error on Ubuntu - x84-32 bit

Asked by Paresh on 2012-01-22

Hi,

I am getting following compilation error. Request your help in resolving this issue.

Linux paresh-desktop 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:10:02 UTC 2010 i686 GNU/Linux

I followed the step as mentioned at "How to install IMTAphy from launchpad.net" on http://www.lkn.ei.tum.de/personen/jan/imtaphy/

openwns-sdk$ ./playground.py install && ./playground.py install --flavour=opt

......

Earlier i got compilation error and i changed the arch in ./modules/phy/imtaphy/SConscript from -m64 to -m32.

IMTAphy has been developed and tested on 64 bit systems only. That's why the architecture (-m64) was set to 64 bits.
I've now added that piece of information to the requirements section on the web page, sorry.

It is certainly possible to make it run on 32 bit environments but I will not support that. For investigating big scenarios the available memory with 32 bit will not be enough anyway.

I recommend you use a 64 bit Linux version.

Cheers
Jan

You need the following additional changes for 32bit:

./modules/phy/imtaphy/SConscript:

externalLIBS.append('mkl_intel_lp64') # Interface Layer

change to

externalLIBS.append('mkl_intel') # Interface Layer

In imtaphy/src/spatialChannel/m2135/M2135.cpp to solve your compiler problem :

std::vector<Phases*> initialPhases(2, NULL);

change to

std::vector<Phases*> initialPhases(2, (Phases*)(NULL));

Still no guaranty it will create correct results if 64bit are assumed for some low-level operations.

Thanks a lot Maciej for the solution. I have incorporated this changes and have compiled the code successfully.

Thanks and Regards,

Hi Paresh,

the fix in imtaphy/src/spatialChannel/m2135/M2135.cpp is part of an update I released today. You can upgrade to that by running "playground.py upgrade" from the openwns-sdk directory.

Details of the update can be found here:
http://bazaar.launchpad.net/~jan-ellenbeck/imtaphy/trunk/revision/30

For 32 bit compilation, you should keep the fix in SConscript and be warned that I haven't tested it at 32 bit.

Could you please mark this question as answered/closed if your original problem has been solved?

Thanks
Jan
