Compilation error on Ubuntu

[johnfxgalea]

I'm trying to compile DECAF on my i686 Ubuntu 14.04 machine, and am facing some compiler issues.

In particular, I am getting the following error:

It seems like this issue has been encountered before: https://groups.google.com/forum/#!msg/decaf-platform-discuss/eFYLlRxaOGg/hv2_2Y6tJaUJ

Finally, my configure command is as follows:

./configure --enable-tcg-taint --target-list=i386-softmmu

Can anybody help me resolve the issue please?

I switched to a 64-bit host and it compiled albeit with some warnings. Given the errors above, I think there is code that is 64-bit specific which therefore yields errors on 32-bit hosts.

Hi,
I think you are right. I noticed that this issue is only associated with 32-bit systems and compilers.
It's most likely a bug in the compiler (specifically gcc-4.8 or newer). See this report for more information: https://www.mail-archive.com/[email protected]/msg428450.html
I do not have a fix for this currently, but FYI, I tried gcc-4.7 on a 32-bit system and it works.

Thanks for the info!
