${resource_name} is empty in make target [message #1708522]

Hi,

I'm trying to get some content-aware builds for my test harness (Ceedling/Unity/CMock). I have added a new target with the following configuration:

Target name: test:this
Make target: test:${resource_name}
Build command: rake

Now, when I build the target I get rake test: and not the expected rake test:MyFile

What am I missing?
The file is in my project viewer, located at src/MyFile.h.

OS: OSX
Eclipse: Eclipse IDE for C/C++ Developers, Version: Mars Release (4.5.0), Build id: 20150621-1200

Thanks in advance for any help!

Edit: Formatting.

Moving this to the CDT forum.

You may be asking in the wrong place as the Project setup for these is rather specific to Unity, etc.

This link may be relevant

There are a number of links (mostly old ones) that pop up when Googling unity eclipse that you may find useful.

Hi,

Thank you for your reply. I do not think this is related to Unity. I did follow the link you supplied and Ceedling is working fine. I can make a new target called test:all and this will run all tests. The issue is I want to edit a file and then only run that files test. This would work if I could get Eclipse to insert the resource's name into the make target, but it only gives me blanks, so Ceedling does not know what to test. I can edit the target and replace ${resource_name} with the name of the file I'm currently editing, but then I would either have one target per module (lots of targets) or I would need to constantly edit the target.

Why does Eclipse not insert ${resource_name}?

Hello,

Quote:

Why does Eclipse not insert ${resource_name}?

because it's not implemented yet or because it's a bug?

I found this in Bugzilla:

https://bugs.eclipse.org/bugs/show_bug.cgi?id=227591
https://bugs.eclipse.org/bugs/show_bug.cgi?id=446176

Maybe you have the skills to help Eclipse to implement this feature?

regard,
Klaus

Maybe because ${resource_name} isn't defined?
Try using ${selected_resource_name} instead. I created a build target with that and the name of the current file is passed to the build command,

You can view the available variables with Project ==> Properties ==> C/C++ Build ==> Build Variables

set Show System Variables at the bottom of the list box. You will need to "edit" dynamic variables to see the current value

I must have been reading some old manual. Thanks for the info about build variables and showing system variables. Found the selected_resource_name there and it works!

Only thing to be aware of is that it won't work unless you actually right-click the resource and select Rebuild Last Target (just building won't work in my case, since this will run the actual target build - not the test build) or hit F9. And selecting and and hitting the target in the Make Target window won't work, because it is not the selected resource anymore.

Many thanks! Smile
