Build system and cleanup, see Issue #8

[schodet]

Here is a first step toward a regular build system.

It includes Makefiles for:

• the lms2012 program and its libraries,
• the d_* modules,
• the programs in lmssrc and their generated data files,
• documentations,
• kernel,
• u-Boot.

If you run make in open_first, it will present a list of available targets.

The build system will automatically build dependencies (for example, c_ui library is needed to build lms2012, and images need to be converted to .xbm to build c_ui).

Not done yet: images and SD cards.

I removed many generated files.

I have also made the connection with eclipse. There is a single project which run make with the selected target. As the workspace is no longer included, you have to import the project in a workspace, using this simple steps:

Before this pull request is committed, the current repository should probably be tagged first.

As the workspace is no longer included, you have to import the project in a workspace, using this simple steps:

Would it be ok to clone it to a local directory and just import it in Eclipse without specifying the git repository as the workspace? i.e., Workspace directory is separate from the ev3sources directory.

[schodet]

@tcwan: tags can be made at any time, at any hash, so order is not important.

I suppose it's OK for the separated workspace. I do not know eclipse well enough.

That is my default setup. I keep my repositories separate from my Eclipse workspace. I just wanted to check if there was any special circumstances for your example configuration.

Does anyone have any objections to merging this pull request?

[tcwan]

It looks ok to me, but please tag the existing repository as well, since all the binaries will be removed, people might want to be able to access the pre-built binaries (via the tagged version) until their setup can rebuild everything correctly.

I don't have a working setup to rebuild everything yet on my end.

[schodet]

I would like to add the instructions for eclipse somewhere, maybe in README.md?

[tcwan]

bungeshea mentioned that we should come up with a proper Wiki but I don't know when/who'll be getting that setup.

[sheabunge]

@tcwan what do you suggest the tag be called?

@schodet Probably best if you add your instructions to a wiki page and link to it from the readme.

@tcwan The wiki is avaliable here: https://github.com/mindboards/ev3sources/wiki Anyone with a GitHub account can edit the wiki. The only thing missing is some established content, but feel free to add some of your own.

[botbench]

I have some content that would be very wiki-able, I was going to make it into a blog article, but the wiki would be better

[tcwan]

@bungeshea: I'm not very inventive when it comes to tags. What about EV3_CODE_DUMP ?

[botbench]

EV3_PRE_BUILDSYSTEM_REVAMP :)

[botbench]

I am currently testing your build system @schodet :)

[botbench]

make kernel produces the following exit message: UIMAGE arch/arm/boot/uImage "mkimage" command not found - U-Boot images will not be built Image arch/arm/boot/uImage is ready make[1]: Leaving directory `/home/ev3builder/ev3sources/extra/linux-03.20.00.13' cp ../../extra/linux-03.20.00.13/arch/arm/boot/uImage uImage cp: cannot stat ‘../../extra/linux-03.20.00.13/arch/arm/boot/uImage’: No such file or directory make: *\ [uImage] Error 1

Is this expected? This was done with a clean tree, just after a checkout.

[botbench]

make lms2012 produces the following errors (again, a clean tree) arm-none-linux-gnueabi-gcc -DPCASM -I../../lms2012/source -I../../c_com/source -I../../c_input/source -I../../c_memory/source -I../../c_output/source -I../../c_sound/source -I../../c_ui/source -I../../../extra/linux-devkit/arm-none-linux-gnueabi/usr/include/dbus-1.0 -I../../../extra/linux-devkit/arm-none-linux-gnueabi/usr/lib/dbus-1.0/include -I../../../extra/linux-devkit/arm-none-linux-gnueabi/usr/include -O0 -Wall -fPIC -c -MMD -MP -o validate.o ../source/validate.c make[1]: * No rule to make target -lusb-1.0', needed bylms2012'. Stop. make[1]: Leaving directory `/home/ev3builder/ev3sources/lms2012/lms2012/Linux_AM1808' make: * [lms2012] Error 2

[botbench]

make programs (with clean tree), produces the following error: cp "Bluetooth/Bluetooth.rbf" "../../lms2012/Linux_AM1808/tools/Bluetooth/Bluetooth.rbf" convert "144x48_POP2.bmp" bitmap.xbm /bin/sh: 1: convert: not found make[2]: * [Bluetooth/144x48_POP2.rgf] Error 127 make[2]: Leaving directory `/home/ev3builder/ev3sources/lms2012/lmssrc/Bluetooth' make[1]: * [Bluetooth.install] Error 2 make[1]: Leaving directory`/home/ev3builder/ev3sources/lms2012/lmssrc' make: *\ [programs] Error 2

What is this convert program? If it's a new build requirement, maybe add it to the README, if it's not already there.

[botbench]

To compile the lms2012 target, the following packages need to be present (Ubuntu 13.04):

• libdbus-1-dev
• libusb-1.0-0-dev
• libbluetooth-dev

[botbench]

To get the /usr/bin/convert program, you need to have installed the imagemagick package.

[botbench]

All issues are resolved now with the installation of u-boot-tools, all targets apart from "programs" compile fine. Do you know where this is coming from? cp "Brick Datalog.raf" "../../lms2012/Linux_AM1808/apps/Brick Datalog.raf" cp: cannot create regular file ‘../../lms2012/Linux_AM1808/apps/Brick Datalog.raf’: No such file or directory make[2]: * [../../lms2012/Linux_AM1808/apps/Brick Datalog.raf] Error 1 make[2]: Leaving directory `/home/ev3builder/ev3sources/lms2012/lmssrc/Brick Datalog' make[1]: * [Brick+Datalog.install] Error 2 make[1]: Leaving directory`/home/ev3builder/ev3sources/lms2012/lmssrc' make: *\ [programs] Error 2

The path seems wrong, I can find the file here: ev3builder@ubuntu:~/ev3sources/lms2012/open_first$ find ../../ -name "Brick Datalog.raf" ../../lms2012/lmssrc/Brick Datalog/Brick Datalog.raf

[schodet]

@botbench:

For kernel, you need the u-boot-tools package. This is documented in the LEGO doc, however I can add a test in the Makefiles to give directions to the user as I have done for the cross compiler.

For -lusb, I think it should not be required to install it unless you are compiling for X86, I think I can fix that.

For convert, I can also add an hint about the package to install.

I will update the pull request with that.

[botbench]

@schodet , the work you've done is incredible, btw, thank you very much!

[schodet]

@botbench thank you! ;)

About the Brick Datalog.raf file, this is a missing mkdir for the destination directory, I will fix that!

[schodet]

I have pushed the fixes, and added a page to the wiki. Thanks for testing!

[sheabunge]

I have created the tag. Is this ready to merge?

[botbench]

I'll test it and let you know

[botbench]

ok, all targets are working as advertised. @bungeshea, let 'er rip, I say :) To you the honours of merging this request.
