Rebuilding the WPILib?

[basicxman]

So I'd like to keep my own development copy of the C++ WPILib, but I'm having some trouble getting it to build as a project in WindRiver. I gather the following needs to be done

1) Download source (done)
2) Import into WindRiver (done)
3) Build...?
4) Run the update script in %root%/Scripts

When I attempt to build the project, nothing happens.
When I attempt to open a workbench shell and use `make` to build the project, no errors occur but nothing happens.

At this point I'm tempted to just make my own Rakefile (ruby version of make) that uses the ccppc compiler and linked, but I'm wondering what the 'correct' way of building the WPI library is.

Why do you need to rebuild WPILib unless you want to modify it? I keep my own copy of the WPILib sources too but for reference only. I did find some scenarios that I need to change the lib but I managed to do it without changing their sources. I either create a new object that inherits the WPILib object and overrides what I need to modify or I just make a copy of the source file and make it part of my project.

Sharing patches with the community is a bonus in my opinion. And why not? This should be something more than possible.

If i may ask, where can i find the sources to the WPIlib?

[mikets]

c:\WindRiver\WPILib\WPILibC++Source20110106rev2242 .zip

Isn't that only helpful if one has already downloaded the sources?
I think the question may have been about where to find the sources if you haven't downloaded them.

Hmm, I just found it in that directory. So I am assuming it either came with the WindRiver software installation or the WorkBenchUpdate that I applied.

It came with the workbench update for me. You can also find it on the WPILib project on FIRST Forge in the Subversion repo.

Back to the original task at hand - maybe Joe Hershberger could shed some light?

Extract the WPILib source to C:\WindRiver\workspace\WPILib. In Workbench, go to File>>Import. Select General>>Existing Projects Into Workspace and click Next. Next to the Select root directory: field, click Browse. Select the C:\WindRiver\workspace\ path. Check the WPILib project in the list box and click finish. The project should now be in Workbench with any other projects you have.

Build like any other... right click on the project and select Build Project.

Thank you, interesting how it didn't work even when I changed the paths in the Makefile.

Joe,

I followed your process for importing the project and it seemed to go smoothly however when I build the project no WPILib.a is produced. I can see WPILib.a as a build target for PPC603gnu and the build console is indicating that it is building the target but the WPILib.a doesn't appear under C:\windriver\workspace\WPILib\PPC603gnu. There is a Makefile in this directory. Please help if you can. Here is the build console output:

Build Started in Project 'WPILib': 2011-01-20 11:40:41
Generation of makefiles started.
Generation of makefiles finished (Elapsed Time: 00:02).
Platform: Wind River VxWorks 6.3
Command: make --no-print-directory BUILD_SPEC=PPC603gnu DEBUG_MODE=1 TRACE=1 clean all
Working Directory: C:/windriver/workspace/WPILib/PPC603gnu
make: removing targets and objects of C:/windriver/workspace/WPILib/PPC603gnu
make: built targets of C:/windriver/workspace/WPILib/PPC603gnu
Build Finished in Project 'WPILib': 2011-01-20 11:40:43 (Elapsed Time: 00:02)

Looking at this output myself now I guess it looks like it is only running a clean?? Do i need to add a build target to make it "make all" somehow?

Thanks!

New this year, the corresponding WPILib source code and reference documentation is installed with each update. You no longer have to hunt for it online only to find that we forgot to post it. You also won't find out-of-date reference doxygen help installed with the update. Each reference help file now includes the update revision number in the title page so you know which release it is documenting.
