Cygwin is spitting error messages - some help please

[nofish]

I'm quite new to developing/compiling, please be gentle...

I tried following the steps found here:
http://www.rockbox.org/wiki/SimpleGuideToCompiling

I got stuck here with Cygwin giving me errors:
(see attached img)

Anyone has a hint what am I doing wrong ?

You don't have the right GCC installed. Run tools/Rockboxdev.sh then select cold fire.

Edit:  Also, the reason we don't recommend using cygwin is that it is very slow.  The dev guide suggests using our preconfigured virtualbox image, since on modern hardware VB is very fast and tends to be no more difficult (or even easier) to use then cygwin.  Something to consider unless you are very familiar with the cygwin environment.

Thanks for your reply.

Done what you said.
So the next steps would be building a cross compiler I guess (if I want to use Cygwin) ?
http://www.rockbox.org/wiki/CrossCompiler

I think that's over my head for now and I'll switch to the virtualbox image.

btw, I know that the virtualbox is recommended over Cygwin, it's just a exercise I'm doing to get familiar with it as I'll be doing a course where we'll be using Cygwin for some stuff.

Rockboxdev.sh builds the crosscompiler.

I got stuck here with Cygwin giving me errors:

The screenshot you attached shows a big fat warning "Your cross-compiler 3.4.6 is not the recommended version 4.5.2! This may cause your build to fail since it may be a version that isn't functional or known to not be the best choice." Is there anything unclear about this so we can improve the message? After all your build did fail and the warning told you this might happen

You're right, I've noticed the big, fat warning message of course.

Sorry for ignoring it in my posts, got a bit overwhelmed as this is all new to me. ..
The actual question for me is 'what would I do to fix it'.

If I run 'Rockboxdev.sh' as said above, does this automatically update to the recommended version or are there further steps necessary ?
 

[bluebrother]

rockboxdev.sh downloads and installs the correct version. Apart from selecting the toolchain to be installed there is no furter action required. Beware that building the compiler can take several hours on Cygwin. If you have an antivirus program running it is a good idea to disable it to speed up the process.

Generally yes.  I'm not sure on cygwin though what will happen to the old compiler.  After installing, you might want to run 'which m68k-elf-gcc' to make sure that the one the command prompt sees is the one you just installed (e.g. is in the location rockboxdev.sh installed to) and not the old one.

still not there yet, but getting closer I hope...

I've run rockboxdev.sh as advised and it completed building the compiler after several hours.

I'm getting the same error message as before though. (see screenshots) What else am I mssing ? Is cygwin still seeing the old compiler ?

PS: I know that I could simply use the Virtualbox image instead, but I'd really like to go through this Cygwin building procedure succesfully once for learning purposes so any help is very appreciated.

[bluebrother]

Did you install the compiler to /opt? rockboxdev.sh defaults to /usr/local, so I assume your installation has the old compiler in /opt. A simple solution would be to make sure the new compiler comes first in the search path. I.e. do something like

export PATH=/usr/local/bin:$PATH

(assuming you used the default installation path for the compiler)

The installation is exactly the same in virtualbox, just much much faster since virtualbox isn't slow like cygwin.

Success !
That did it, it's now building without errors.
Phew, thank you both a lot for your patient help.

PS:
After this experience, I'd be willing to help help updating the relevant Wiki pages if this is planned.
For example
http://www.rockbox.org/wiki/SimpleGuideToCompiling
it took me a bit to find out that the link about SVN is no longer valid etc.

Such things aren't planned -- people willing to work in it do the work, and if nobody wants to do the work for something nobody does the work If you're willing to update the wiki: great! Get yourself a wiki account and fix the pages that are wrong / out of date. I'd suggest to also join on IRC to be able discussing things
