A110 Toolchain versions

[thica]

Hello all,

in the past, I used Lundmans toolchain to compile apps for the a110 and everything works fine.

Yesterday I started to compile an application , using some syabas libs on the a110, and during linking and i got strange unresolved externals (like "__divdi3@GCC_3.0"

Lundmans toolchain is using gcc 4.2.2, while the syabas official toolchain contains gcc 4.0.4 with a lot a patches. Did anybody experienced similar problems or is anybody using the syabas toolchain with success? (I try to avoid to setup a scnd development environment, befor I know, that it will work).

Hi,

I'm a happy user of the official syabas toolchain with gcc 4.0.4 and have not experienced any problems using it on an A100. It needed some additional patching to build out of the box, but after that it just works. I'm using it already more than a year now for all kinds of different C/C++ libraries/projects.

Thx for your reply, than I will need to setup the officical toolchain. If I face problems with he patching , I will come back to you... :-)

[SoloHan]

Let me know if you run into any problems...

I'll be back after the weekend, so be a little patient for a reply from me

Hello, made some tries with preconfigured vware images for nmt development, but all of them are based on Lundmans toolchain. (which does not work if you link against some special sigma libs on the nmt)
So I did setup my own vmware image with the the sigma toolchain , using the following directions

http://www.geordy.nl/?p=26

After trying several Ubuntu Images , I succeeded with Ubuntu 7.xx to compile the toolchain, with the default settings from menuconfig. With this toolchain I am able to compile/link my app without strange unresolved externals.
Unfortunately , if I try to execute a binary (even Hello world) on the a110 , I get an error

./hello: can't resolve symbol '__uClibc_start_main'

So some help would be great.

@SoloHan: Weekend is over.. :-) Any Ideas?

After seeing this I tried to do a quick toolchain setup, I have working toolchains for the 200 and some arm based units but never made one up for the 100.. unfortunately I haven't had time to get a drive into a 100 series so I could test my hello. I had used a non-gui install of debian and the reason i'm replying is I noticed a couple things but without being able to test I couldn't verify if it was a problem. first I noticed the warning about compiling the toolchain with gcc 4.x and the second thing I noticed was it appeared uClibc didn't compile and errored out but it didn't stop the build from finishing up.. and last there was an issue on the link about static linking pointing to lundmans page..

not sure it will help but might be somethign to look into.

Hi thica,

Weekend is indeed over I had a small holiday appended to the weekend, so I had a loooong weekend

Get the toolchain sources from here:
http://www.networkedmediatank.com/downlo...05.tar.bz2

On Ubuntu 9.10 you have to install the following packages:

• flex
• bison
• gettext
• genromfs
• ncurses-dev
• patch
• texinfo (for makeinfo)
  

1. Install the packages:
   
   Code:
   

   sudo aptitude install flex bison gettext genromfs ncurses-dev patch texinfo
2. Extract the toolchain:
   
   Code:
   

   tar xvf <path>/smp86xx_toolchain.20080505.tar.bz2
cd smp86xx_toolchain.20080505
3. Extract the smp86xx_toolchain.20080505-patches.tar.gz file in the toolchain directory:
   
   Code:
   

   tar xvf <path>/smp86xx_toolchain.20080505-patches.tar.gz
4. Now run the following command to configure the toolchain:
   
   Code:
   

   make menuconfig
   
   Use the following toolchain options or load them from the file: "pch-a100.config".
   
   Select the "Load an Alternate Configuration File" option to load the "pch-a100.config" file.
   
   Toolchain options:
   
   Code:
   

   kernel headers: 2.6.11.0
uclibc: 0.9.28.3
binutils: 2.17
gcc: 4.0.4
gdb: 6.3

Common options:
Enable multilib: yes
Enable largefile: yes
Use soft FP: yes

Target optimizations: "-o2 -pipe"
   
   After you have loaded or set the toolchain options, select <exit> and save the new configuration.
5. Now build the toolchain:
   
   Code:
   

   make

This will take some time, so take a cup of coffee and enjoy the sunny weather

Great, awaiting your patches, then I will give it a try...

[dc11ab]

@SoloHan, please could you share the patches? I was thinking of adding them to the NMT wiki, together with your instructions above.

[thica]

btw: is menuconfig not required?

[SoloHan]

@thica: Yes, menuconfig is required. I was thinking of supplying an external config file, so you can load it instead of typing over all settings.

@dc11ab: I'm currently verifying the patches in a clean environment. When the toolchain is successfully build, I'll send/post the patches. Should I send you the patch file, because I cannot post it here

SoloHan

[dc11ab]

Sure, you can send the patch to me, or if you're in the mood you can upload it yourself to the wiki
http://www.networkedmediatank.com/wiki/i...ial:Upload
Maximum file size: 64 MB
Permitted file types: (png, gif, jpg, jpeg), tar, tgz, zip, gz.

I think the NMT wiki needs a serious overhaul when it comes to the 'building toolchain' part. I have managed to make one for the A100, but somehow not managed to get the SMP8643 toolchain working yet. It's frustrating being a *nix amateur...

[accident]

I would also like to see the patches

[SoloHan]

OK, I'll upload the patches using your link. Thanks. I'll make the final tar ball tomorrow and upload it.

I will let you know when it is done.

SoloHan.
