CCS/AWR1642BOOST: Makefile for CCS project , sources.mk error : empty variable name

Hi,

Is it possible to use the default CCS project which you can find from TI-Rex?

Or in the existing project you need to go to Project Properties->Build->C6000 Compiler->Edit Flags, here you can edit or remove the flags if it is not getting set from the GUI setting.

HI Jitendra

Thanks your reply 

I have already tried those two method that you mentioned. Unfortunately, the error can't be eliminated.

And i also try to use the example project which is built-in CCS project (like Hello project) . But the result is the same.

I find out the problem is that when the setting of project property is changed, the sources.mk file will keep saving this modification EVEN IF the setting is change to default.

And, this sources.mk affect all project when doing compile 

However, when i uncheck the "Generate Makefiles automatically", the project can be compiled successfully , like following picture

My question is about why the sources,mk file keep all the modification of project property.

And it can't be change to default even if the setting of project property is back to default setting 

Is it related to the setting of GNU compiler in CCS or eclipse IDE?

Hi Marcus,

I would suggest you to refer to the "mmWave SDK Demo" Lab in the TI Resource Explorer. This provides you the CCS projects for the mmWave OoB demo for AWR14xx/AWR16xx.

HI, Raghu

Thanks your reply.

Actually, i have used the project which is  "mmWave SDK Demo" project in the TI Resource Explorer to compile.

But the result of compilation always fails. Like the reason that i have mentioned above.

This files (sources.mk) is always wrong, and the error message is following 

 sources.mk:43: *** empty variable name.  Stop.

Thanks, 

Marcus 

Markus,

The MMWAVE-SDK that the CCS project expects is ver2.0.0.4 . Have you installed this version of the SDK for building the demo using the CCS ?

If you have changed the version of the SDK then you will get these errors as there are some other dependent tools for different versions of SDK.

HI, Raghu 

Yes, my MMWAVE-SDK  version is 2.0.0.4

I have used this version to build the other labs demo in CCS IDE before. Like Short range radar 

After make file error happened, i can't use this version to build any project that i have build already before 

Due to this situation, I think that maybe it's the GNU compiler problem or IDE setting problem which is probably related to the automatically-generated ".mk" file.

Could i use the higher CCS version to build the project which is in MMWAVE-SDK ver.2.0.0.4? 

Thanks, 

Marcus.

Marcus,

I have used a CCS version 7.4 to build this mmW demo code . I do not see any issue when building.

Could you delete the SDK demo project from your project explorer and re-check it?

HI, Raghu 

Thanks your patience on this issue.

The method that you mentioned have been tried before. unfortunately, the error is still here.

I think if you could modify the CCS project properties with wrong setting, like following figure 

 Properties->Build->C6000 Compiler->Advanced Options->Default File Extensions->Extension for Object files 

you will meet the situation that i saw in sources.mk files , like following figure

And after above error modification, The error will be saved in sources.mk file. like above fluorescent yellow 

if you change the project property to the correct setting, like following figure 

The error that happened in sources.mk file can't be modified correctly EVEN if the project property is correct.

The above process is the reason of this issue. 

And, this all the method we discuss in this thread so far could't solve this problem.

Thanks your help

Best regards.

Marcus,

The point I am trying to make is that if you have all the dependent tools and the right SDK installed you will not need to changes any of the settings in any of the projects. They will build successfully without any issues. 

I believe there is some  corruption that have happened in some of the dependent files and that is causeing the build issue.

BR,

Raghu

Raghu

Yes, there is some error that result in this build issue

But now, the error come from the sources.mk makefile

I really want to know how to correct the dependent files such that the makefile can be modified correctly.

Do you have any idea or suggestion on this issue? 

Thanks your help!

best regards

Marcus 

Marcus,

If the issue is happening with all the project builds, I would suggest to re-install all the tools and retry.
