(That's why I showed it working in one shell command line.) If you mean before I started the compile, I'd touched a bunch of ScPostIt* related files in sc/inc and sc/source/core/data. However, I churned through the slow build time about 20 times last night until I was finally able to build 'sc'. Now the behavior seems to be correct, in that only the necessary files are actually built. I.e. I can no longer recreate that behavior. From the outside, it smells to me like there is a transactional behavior defined in the make files. That is, if all the files of a certain transaction don't get built properly, then the build redoes all of them. Is that expected/intentional behavior? Or did I just hit some corner case in my sc/ modifications? Should not at least the first 3 completed executions no longer need to be re-executed? Yes. Could you check the timestamps of (1) [...]/workdir/unxlngx6.pro/Dep/CxxObject/sc/source/filter/dif/difexp.d being newer than (2) [...]/workdir/unxlngx6.pro/CxxObject/sc/source/filter/dif/difexp.o and that again being newer than (3) [...]/sc/source/filter/dif/difexp.cxx , please? Last night, (2) was newer than (1), (1) was newer than (3). Now, after a couple of successful builds, (3) is newer than (2), which is newer than (1). Summary (= == younger than): Before success: (2) = (1) = (3) After success: (3) = (2) = (1) In any event, since I can't recreate it anymore, and it seems to be working fine, I'm moving on ...

[Libreoffice] how to 'make' a single target?
Hullo List, I'm currently working in the sc/ module, and I'm in the make small change, re-compile, make small change, re-compile stage. This is proving very cumbersome, however, as I'm unable to re-make just the affected files. For instance, note my attached output, showing the output of $ make -j1 | head; sleep; make -j1 | head Should not at least the first 3 completed executions no longer need to be re-executed? This is frustrating because it results in a latency of 5+ minutes on my slow 2-core machine before I can see the results of a code change. Are there any pointers for me on how I can compile _just the exact_ piece of code on which I'm working (and affected other snippets, of course)? Thanks, Kevin $ .

Hello Kevin, 2011/10/30 Kevin Hunter hunt...@earlham.edu: Hullo List, I'm currently working in the sc/ module, and I'm in the make small change, re-compile, make small change, re-compile stage.

Are there any pointers for me on how I can compile _just the exact_ piece of code on which I'm working (and affected other snippets, of course)? Use make build -srj2 but leave out the build at least once before creating the patch or pushing your changes. What needs most time is linking and executing our unit tests and with make build you skip the tests.

Are there any pointers for me on how I can compile _just the exact_ piece of code on which I'm working (and affected other snippets, of course)? You can build without unitchecks by doing a: (. ../Env.Host.sh make build) You make it ignore header dependencies by doing a: (. ../Env.Host.sh make gb_FULLDEPS= build) Then only objects get rebuild if you touched the cxx directly. If you do a: (. ../Env.Host.sh make gb_FULLDEPS= -W `readlink -f source/filter/dif/difexp.cxx` build) only difexp.cxx gets recompiled and relinked, even if it wasnt directly changed.
