New Xmos libraries

[Folknology]

Today I was using the new version of the I2C library (lib_i2c) for a simple test on some new hardware, however after adding in dependencies of lib_xassert and lib_logging The make compile cycle started generating pages of errors, most of which were about duplication of main. In order to move forward I had to delete the 'tests' subfolders in these libraries which contained the additional sources containing 'main'.

I am guessing this shouldn't really happen and that the tests sources should have a separate target that doesn't interfere with the main app I am building. I think it has something to do with new libraries versus the old module style which I haven't had issues with historically. Clearly I am missing something or some configuration detail with using these new libraries, perhaps someone can pass me the clue stick...

Hi,
I tried to download the lib_i2c using the xTIMEcomposer v14.x - It asks for a selection of tests to download into the workspace, at the time of lib download (attached the snapshot for reference).
Did you try in the similar way?

I do not use the xTIMEcomposer IDE, I just use the command line tools directly, so in my case I manually downloaded the zipped files from Xmos's Design support/libraries area (http://www.xmos.com/support/libraries). I then just added them into my makefile using the 'USED_MODULES' variables list. I saw no request for any test selection.

Could be a bug in the build system. Where is lib_i2c with respect to your application on your file system. Is it like this:

Code: Select all

my_app/
   Makefile
   src/
lib_i2c/ 
   lib_i2c/
       module_build_info
       api/
       src/

or some other configuration?

Hi Dave, yes my config is as your suggestion (I just did the same thing I used to do with the older modules).

Ok I now have had time to revisit this error after getting my urgent I2C test to do its job and get the hardware out. Just to remind you I did this by removing all tests and example subdirectories from the libraries. I do this all on the command line no IDE, below is a bit more detail showing the output of the make.

I have now created a separate test area for this with just the libraries and my I2C code:

Most of the errors are about duplicate definitions, hope this info enables you to work out what's actually going wrong..
