TODO this page needs updating.
The following assumes that you already have a built tree rooted in openxt.git with a completed build. It also assumes the build was done with with INHIBIT_RMWORK set. INHIBIT_RMWORK is set by default, and tells the build scripts to not delete the temporary packages build folders, so that we can go there, modify and rebuild source code.
...
| Rule | Description |
|---|---|
makeclean | Run a proper "make clean" inside the build folder. IMPORTANT: rebuilding without cleaning could not do what you expect, like with Xen recipes. makeclean also does a force_rebuild |
force_rebuild | Brings the state of the package back (usually from "done building") to "needs compiling" |
cleansstate | Cleans the package and removes its state (which means "initial state" to OE) |

Let's say trousers build failed because of a typo in the code, here's how to fix it (some of the steps here can usually be skipped, like the rebuild at the beginning):
$ cd build-scriptsopenxt.git/build/oe
$ ./bb -c cleansstate trousers && ./bb trousers # rebuild the package to make sure it's clean
$ less tmp-eglibc/work/core2-oe-linux/trousers-0.3.2-1-r2/temp/log.do_compile # figure out what failed
$ emacsvi tmp-eglibc/work/core2-oe-linux/trousers-0.3.2-1-r2/trousers-0.3.2-1/src/tcs/tcs_caps.c # fix it
$ ./bb -c makeclean trousers # which $does ./bba -c force_rebuild trousers
$ ./bb trousers
$ dpkg -c tmp-eglibc/work/core2-oe-linux/trousers-0.3.2-1-r2/deploy-ipks/core2/trousers_0.3.2-1-r2_core2.ipk # check the contents of the final package...
