undefined reference to `arm_std_f32'

[SW_SST]

Hi all.
I'm still on my everlasting struggle to get the firmware compiled. We have several on our team working on this, and so far no one has been able to compile and link. If we don't succeed soon, we will be forced to stop using AutoQuad in our products and move to PixHawk (where the compilation is easy, and uses only free tools).

After a lot of messing around, and removing some files that were "XXXX.patched.c" that caused multiple definition errors,
I'm down to about 30 link errors. All are from the math library, and look like this :

undefined reference to `arm_std_f32'
undefined reference to `arm_mat_init_f32'
undefined reference to `arm_mat_trans_f32'
undefined reference to `arm_fill_f32'
undefined reference to `arm_mat_mult_f32'

Once again, this is becoming urgent and embarrassing. I have invested whole days , I've read all the forum posting and wiki pages I could find, and I'm still not able to compile. Something is missing, in the documentation or the files.
Please advise,

I pulled the most recent repo code, installed the needed libraries into a fresh directory. In Crossworks, open an existing project and navigate to the onboard directory and select autoquad.hzp. Hit the compile button and 1:37 later, it completes.

I zipped up the directory structure below. If this does not work for you, then you have Crossworks somehow setup incorrectly.

Also I just uploaded to our FTP site, in case that makes a difference.

Wow ! it finally works.

Thanks for uploading v1.3 , I'm not sure if 1.4v works on not (I will test later), but 1.3 is impossible to find.

Also, there is a difference if you double-click the CrossStudio solution file (which I have been doing until now), or if you choose "Open-Solution" from the CrossStudio menu. The first does not compile and complains about missing folders/files, and the second does. Very lame.

Thanks everyone for you help.

Has anyone tried compiling with CrossStudio 3.x ?

[aBUGSworstnightmare]

Yes, with 3.1, 3.2 and 3.3.

Be sure to look at this too; might cause you some issues: viewtopic.php?f=31&t=3825&start=10#p26961
