Distractions

Look what arrived today at my house after 3 months of waiting. Now how am I supposed to get any work done on the MD addin?!

Now...let's get Cobra running on this bad boy

Looks like Mono works for the most part:

Hmm, the "for the most part" seems important. I tried it out last night. The devil is always in the details.

It looks like Mono has issues with floats on ARM when the hard-float ABI is used. The unit tests for DecimalTools fail as it appears that the square root of 1 returns 0 on Raspbian (optimized version of Debian for Raspberry Pi). I was able to reproduce this in C# by casting a decimal to a float so it's not Cobra specific.

I'm going to try regular Debian for ARM which still uses the soft-float ABI. I think I'll have better luck.

[Charles]

Let us know how it goes.

[nerdzero]

Success!

It's quite slow though. I ran it a second time with -timeit:yes. See below for results.

I'm going to play with it a bit and see if it will be suitable for the application I want to use it in. I might have to wait for a fix on Mono to run Raspbian or maybe look into overclocking.

==== Clean up workspace

==== Install "cobra" into a system path directory

found in PATH: /usr/local/bin/cobra
copy from: /usr/local/cobra/bin/cobra
       to: /usr/local/bin/cobra

The existing "cobra" in your path at
/usr/local/bin/cobra
has been replaced with the new one.

==== Change directory instruction

Now that Cobra has been installed, pleased change out of the
current directory, such as:

cd ../..

The installer does plenty of file I/O. Depending on how slow your storage is, that might dominate the time. Of course, that could be true for your intended app as well.

Don't forget you can use -turbo (or the individual options it triggers) to improve run-time performance.

[Charles]

Is the storage for the Raspberry based on flash?

http://www.techspot.com/news/50428-sams ... t19-direct

[nerdzero]

Yep, runs off an SD card. Haven't benchmarked it yet to see what kind of I/O speeds I'm getting. Also, for compiling the compiler, I am betting it had to use swap space.

Interesting link btw.
