---|
10 | .. index:: Git |
---|
11 | |
---|
12 | RTEMS provides open access to it's development processes. The project encouages |
---|
13 | all users to inspect, review, comment and contribute to the code base. The |
---|
14 | processes described here are the same processes the core development team use |
---|
15 | when developing and maintaining RTEMS. |
---|
16 | |
---|
17 | Please read :ref:`development-hosts` before continuing. |
---|
18 | |
---|
19 | .. warning:: |
---|
20 | |
---|
21 | The development version is not for use in production and it can break from |
---|
22 | time to time. |
---|
23 | |
---|
24 | The following procedure assumes you have installed and configured your host |
---|
25 | operating system. It also assumes you have installed any dependent packages |
---|
26 | needed when building the tools and the kernel. |
---|
27 | |
---|
28 | You need to select a location to build and install the RTEMS Tool chain and |
---|
29 | RTEMS. Make sure there is plenty of disk space and a fast disk is |
---|
30 | recommended. Our procedure will document building and installing the tools in a |
---|
31 | home directory called :file:`development/rtems`. Using a home directory means |
---|
32 | you can do this without needing to be root. You can also use |
---|
33 | :file:`/opt/rtems/build` if you have access to that path. |
---|
34 | |
---|
35 | The location used to install the tools and kernel is called the `prefix`. It is |
---|
36 | best to have a `prefix` for each different version of RTEMS you are using. If |
---|
37 | you are using RTEMS 4.11 in production it is not a good idea to install a |
---|
38 | development version of 4.12 over the top. A separate `prefix` for each version |
---|
39 | avoids this. |
---|
40 | |
---|
41 | The RTEMS tool chain changes less often than the RTEMS kernel. One method of |
---|
42 | working with development releases is to have a separate `prefix` for the RTEMS |
---|
43 | tools and a different one for the RTEMS kernel. You can then update each |
---|
44 | without interacting with the other. You can also have a number of RTEMS |
---|
45 | versions available to test with. |
---|
46 | |
---|
47 | This procedure will build a SPARC tool chain. |
---|

68 | .. sidebar:: *Downloading the source* |
---|
69 | |
---|
70 | You need an internet connection to download the source. The downloaded source |
---|
71 | is cached locally and the RSB checksums it. If you run a build again the |
---|
72 | download output will be missing. Using the RSB from git will download the |
---|
73 | source from the upstream project's home site and this could be `http`, `ftp`, |
---|
74 | or `git`. |
---|
75 | |
---|
76 | Check all the host packages you need are present. Current libraries are not |
---|
77 | checked and this includes checking for the python development libraries GDB |
---|
78 | requires: |
---|

204 | RTEMS Kernel |
---|
205 | ------------ |
---|
206 | |
---|
207 | We need to set our path to include the RTEMS tools we built in the previous |
---|
208 | section. The RTEMS tools needs to be first in your path because RTEMS provides |
---|
209 | specific versions of the ``autoconf`` and ``automake`` tools. We want to use |
---|
210 | the RTEMS version and not your host's versions: |
---|
211 | |
---|
212 | |
---|
213 | .. code-block:: shell |
---|
214 | |
---|
215 | $ export PATH=$HOME/development/rtems/4.12/bin:$PATH |
---|
216 | |
---|
217 | Create a new location to build the RTEMS kernel: |
---|
218 | |
---|
219 | .. code-block:: shell |
---|
220 | |
---|
221 | $ cd |
---|

238 | |
---|
239 | The developers version of the code from git requires we ``bootstrap`` the |
---|
240 | source code. This is an ``autoconf`` and ``automake`` bootstrap to create the |
---|
241 | various files generated by ``autoconf`` and ``automake``. RTEMS does not keep |
---|
242 | these generated files under version control. The bootstrap process is slow so |
---|
243 | to speed it up the RSB provides a command that can perform the bootstrap in |
---|
244 | parallel using your available cores. We need to enter the cloned source |
---|
245 | directory then run the bootsrap commands: |
---|
246 | |
---|
247 | .. code-block:: shell |
---|
248 | |
---|
249 | $ cd rtems |

323 | |
---|
324 | We build RTEMS in a directory outside of the source tree we have just cloned |
---|
325 | and ``bootstrapped``. You cannot build RTEMS while in the source tree. Lets |
---|
326 | create a suitable directory using the name of the BSP we are going to build: |
---|
327 | |
---|
328 | .. code-block:: shell |
---|
329 | |
---|
330 | $ cd .. |
---|
331 | $ mkdir erc32 |
---|
332 | $ cd erc32 |
---|
333 | |
---|
334 | Configure RTEMS using the ``configure`` command. We use a full path to |
---|
335 | ``configure`` so the object files built contain the absolute path of the source |
---|
336 | files. If you are source level debugging you will be able to access the source |
---|
337 | code to RTEMS from the debugger. We will build for the ``erc32`` BSP with POSIX |
---|
338 | enabled and the networking stack disabled: |
---|
339 | |
---|
340 | .. code-block:: shell |
---|
341 | |
---|
342 | $ $HOME/development/rtems/kernel/rtems/configure --prefix=$HOME/development/rtems/4.12 \ |

515 | Contributing Patches |

516 | -------------------- |
---|
517 | |
---|
518 | RTEMS welcomes fixes to bugs and new features. The RTEMS Project likes to have |
---|
519 | bugs fixed against a ticket created on our :r:url:`devel`. Please raise a |
---|
520 | ticket if you have a bug. Any changes that are made can be tracked against the |
---|
521 | ticket. If you want to add a new a feature please post a message to |
---|
522 | :r:list:`devel` describing what you would like to implement. The RTEMS |
---|
523 | maintainer will help decide if the feature is in the best interest of the |
---|
524 | project. Not everything is and the maintainers need to evalulate how much |
---|
525 | effort it is to maintain the feature. Once accepted into the source tree it |
---|
526 | becomes the responsibility of the maintainers to keep the feature updated and |
---|
527 | working. |
---|
528 | |
---|
529 | Changes to the source tree are tracked using git. If you have not made changes |
---|
530 | and enter the source tree and enter a git status command you will see nothing |
---|
531 | has changed: |
---|
532 | |
---|
533 | .. code-block:: shell |
---|
534 | |
---|
535 | $ cd ../rtems |
---|
536 | $ git status |
---|
537 | On branch master |
---|
538 | Your branch is up-to-date with 'origin/master'. |
---|
539 | nothing to commit, working directory clean |
---|
540 | |
---|
541 | We will make a change to the source code. In this example I change the help |
---|
542 | message to the RTEMS shell's ``halt`` command. Running the same git status |
---|
543 | command reports: |
---|
544 | |
---|
545 | .. code-block:: shell |
---|
546 | |
---|
547 | $ git status |
---|
548 | On branch master |
---|
549 | Your branch is up-to-date with 'origin/master'. |
---|
550 | Changes not staged for commit: |
---|
551 | (use "git add <file>..." to update what will be committed) |
---|
552 | (use "git checkout -- <file>..." to discard changes in working directory) |
---|
553 | |
---|
554 | modified: cpukit/libmisc/shell/main_halt.c |
---|
555 | |
---|
556 | no changes added to commit (use "git add" and/or "git commit -a") |
---|
557 | |
---|
558 | As an example I have a ticket open and the ticket number is 9876. I commit the |
---|
559 | change with the follow git command: |
---|
560 | |
---|
561 | .. code-block:: shell |
---|
562 | |
---|
563 | $ git commit cpukit/libmisc/shell/main_halt.c |
---|
564 | |
---|
565 | An editor is opened and I enter my commit message. The first line is a title |
---|
566 | and the following lines form a body. My message is: |
---|
567 | |
---|
568 | .. code-block:: shell |
---|
569 | |
---|
570 | shell: Add more help detail to the halt command. |
---|
571 | |
---|
572 | Closes #9876. |
---|
573 | |
---|
574 | # Please enter the commit message for your changes. Lines starting |
---|
575 | # with '#' will be ignored, and an empty message aborts the commit. |
---|
576 | # Explicit paths specified without -i or -o; assuming --only paths... |
---|
577 | # |
---|
578 | # Committer: Chris Johns <chrisj@rtems.org> |
---|

---|
580 | # On branch master |
---|
581 | # Your branch is up-to-date with 'origin/master'. |
---|
582 | # |
---|
583 | # Changes to be committed: |
---|
584 | # modified: cpukit/libmisc/shell/main_halt.c |
---|
585 | |
---|
586 | When you save and exit the editor git will report the commit's status: |
---|
587 | |
---|
588 | .. code-block:: shell |
---|
589 | |
---|
590 | $ git commit cpukit/libmisc/shell/main_halt.c |
---|
591 | [master 9f44dc9] shell: Add more help detail to the halt command. |
---|
592 | 1 file changed, 1 insertion(+), 1 deletion(-) |
---|
593 | |
---|
594 | You can either email the patch to :r:list:`devel` with the following git |
---|
595 | command, and it is `minus one` on the command line: |
---|
596 | |
---|
597 | .. code-block:: shell |
---|
598 | |
---|
599 | $ git send-email --to=devel@rtems.org -1 |
---|
600 | <add output here> |
---|
601 | |
---|
602 | Or you can ask git to create a patch file using: |
---|
603 | |
---|
604 | .. code-block:: shell |
---|
605 | |
---|
606 | $ git format-patch -1 |
---|
607 | 0001-shell-Add-more-help-detail-to-the-halt-command.patch |
---|
608 | |
---|
609 | This patch can be attached to a ticket. |
