No warning/error explanations in code composer

Are you referring to the Problems view in CCS? Do you see a more detailed message in the CCS build console?

Could attach screenshots of both the CCS build console and Problems view showing the issue?

Apparently yes I see a more detailed answer in the build console.

Can you show the part in the build console where the warnings #552 and #66 appear?

One known issue that I am aware of is if the warning message spans more than one line, and the build option --diag_wrap is NOT set to off, then the warning text will not appear in the Problems view. This is because, with that diag_wrap setting. the Problems view displays whatever appears in the first line of the warning message but not the rest. However, I see that you have --diag_wrap=off so I am not sure why it is not showing the text.

If this is reproducible with a small test project that you can share with us, we can look into it some more.

I really dont have time to make a test project right now. Last week i was able to get complete error messages from some of my projects. Now the problem has spread to those as well.

Seems I have found the cause. Under CCS build-->C6000 compiler->advanced options->diagnostic options there is a checkbox "Verbose diagnostics". It needs to be unchecked in order for warnings to be displayed properly. Shouldnt it be the other way around?
