Whoops, sorry Farzana, that's the bit of info that we needed.? We at Wallaroo Labs have overlooked an important bit of documentation: Wallaroo does not support 32 bit platforms.? If you have a 64 bit version of Ubuntu Trusty available, please use it.
If you only have 32 bit hardware available, our apologies.? From what I can see in the Pony compiler's main README, there is no clear text that says that the 32-bit Pony compiler cannot yet pass its full test suite.? I will open bug reports on both repos to request clearer documentation for 32-bit and 64-bit platforms.
