[Pianod] Compiling on Raspberry Pi A+

[Perette Barella]

Darren,

‘Illegal instruction’ from the compiler is bad news, like the hardware is screwed up.  Bad memory, bus problems… but let’s start with the fixable ones.  If you’re overclocking the pi, set it back to normal.  If you’re using some no-name SD card, try a reputable one; if it’s an old one, replace it; if it’s new and reputable try a different brand in case there’s a bad piece or batch.

You could do something like this to make sure what’s being written to the SD card is consistent
- Get the free space on the device:
$ df -k .
Filesystem     1K-blocks    Used Available Use% Mounted on
/dev/root       15183756 5530452   8980448  39% /

- Now make a temp file a little smaller than the free capacity.  dd uses 512-byte blocks:
dd if=/dev/random count=30000000 | tee foobar | cksum

- When that completes
cksum foobar

- If the checksums don’t match… then I/O to your SD card isn’t being consistent.  Of course, this checks free space, and there could be bad areas that contain operating system and the compiler.

What are the outputs of `uname -a` and `g++ --version`?

The automatic script ran against February’s Raspbian release.  Testing it against the May Raspbian release is on my to-do list.

Skipping ahead, I am now trying to finish without the script by doing a make in the pianod sources directory.  And, although extremely slow, it did work to a point where it finally failed.  The output suggested creating a bug report.  So, do you have any idea why this failed?  I'll try compiling again, just in case maybe my pi ran out of resources or something and just gave an erroneous error.  But, I have little hope that will work.
