Description Ladislav Laska 2015-03-06 21:00:24 UTC
The crossdev fails to install msp430 target properly: all the mcu specific headers, previously provided by cross-msp430/msp430mcu are missing, and thus no code can be compile for this architecture. See the attached msptest.c, that should be compiled by command 'msp430-gcc msptest.c -mmcu=msp430g2553'.

Reproducible: Always

Steps to Reproduce:
crossdev -t msp430
msp430-gcc msptest.c -mmcu=msp430g2553
Actual Results:  
krakonos@ibex ~ $ msp430-elf-gcc -mmcu=msp430g2553 msptest.c 
msptest.c:10:20: fatal error: msp430.h: No such file or directory
 #include <msp430.h>
                    ^
compilation terminated.


Expected Results:  
Working binary created.

Comment 3 SpanKY gentoo-dev 2015-03-09 01:06:19 UTC
Tim should let me know what i need to fix ;)

however, you should post the crossdev summary when filing related bugs.  what does this show:
$ qlist -Iv msp430
Comment 4 Ladislav Laska 2015-03-09 01:12:59 UTC
krakonos@ibex ~ $ qlist -Iv msp430 
cross-msp430-elf/binutils-2.25
cross-msp430-elf/gcc-4.9.2

I'm not sure how to get more info from crossdev, the options don't say much. Maybe this could help?:

(In reply to Ladislav Laska from comment #4)

why don't you have cross-msp430-elf/newlib installed ?  if you don't have a C library, then trying to use headers from it isn't going to work.

did you unmerge it ?  how exactly did you run crossdev the first time ?

> Tim should let me know what i need to fix ;)

Ah yes, I should probably revive msp430mcu and toss TI's generic tarball dump into some sort of snapshot format and fix up crossdev a bit. URLs for reference:

TI's msp430 gcc homepage: http://www.ti.com/tool/msp430-gcc-opensource

Linker scripts are under support files (or at this url):

Comment 7 Ladislav Laska 2015-03-09 10:39:15 UTC
Well, I just installed it and nothing changed. I originally found this out on a friend's laptop, and then installed it on my server to test, with a -s1 switch. I want to keep my old toolchain on desktop, for work.

Now I have:
krakonos@ibex ~ $ qlist -Iv msp430
cross-msp430-elf/binutils-2.25
cross-msp430-elf/gcc-4.9.2
cross-msp430-elf/newlib-2.2.0.20150225

> Well, I just installed it and nothing changed.

I thought my reply was clear. If not, currently you'll need to take the linker scripts from the tarball in comment #6, and drop them somewhere like /usr/msp430-elf/lib. I'll toss them in an ebuild soon to fix things.
Comment 9 Ladislav Laska 2015-03-09 14:13:09 UTC
It was not. This fixes it, but I'll be looking forward for an ebuild. 

Thanks!
Comment 10 SpanKY gentoo-dev 2015-03-09 17:43:48 UTC
(In reply to Ladislav Laska from comment #7)

well, if you used the -s1 flag, you shouldn't be surprised when you don't have any C library headers.  crossdev gave you what you asked for.

i'll leave it to Tim whether he wants to punt this as INVALID or relabel it as generic msp430mcu support.

support files ebuild


indeed, I tried using crossdev to compile a msp430 target only to find that most of the header and ld files were missing. 
I installed the latest support files from the TI site (see ebuild) - the compiler worked but the linker borks up.

Comment 12 Petre Rodan 2015-12-19 12:10:57 UTC
OK, I soon found out that default newlib generates code that is too big for most msp430 mcus out there. I will try to generate packages based on a tweaked 'nano' spec that resemble the mspgcc behaviour.

Re-assigning since I don't have any msp430 hardware on hand anymore.
