[Buildroot] [Question] How do I build source code at source folder?

[Eric Hsieh]

Hi everyone,

Now, Im trying to create a special mode which can help me to build source
code at source folder instead of output/build folder. I checked the makefile
at package, looks like there is no directly way to be done.
So, I would like to ask is it possible to be done? If yes, please give me
some tips. Thanks.

If you want to build a package from an external source folder you can
specify the source directory by creating the  $(CONFIG_DIR)/local.mk
file and set the <pkg>_OVERRIDE_SRCDIR varialbe. But this will
copy/rsync your sources and build your package at output/build.

Please check "8.13.6. Using Buildroot during development" in the
buildroot user manual for more information about that.

[Buildroot] [Question] How do I build source code at source folder?

[Psychesnet Hsieh]

Hi Heiko,

Thanks and yes, I know I can use _OVERRIDE_SRCDIR to define local folder as
source.
But what I need is directly build source code at source folder without
copy/rsync.
And eventually the target object will install into output/fakeroot folder.
Do you have any idea to get it done? Thanks.

I don't understand why you need to build in the source directory. Can
you give some more background information about that?

That is not possible.

[Buildroot] [Question] How do I build source code at source folder?

[Psychesnet Hsieh]

Hi Heiko,

From previous and some projects, we would like to build 3 kinds of source
code in our code base.
1. Directly build from open source, like lighttpd and ffmpeg. Basically, we
don't need to change this a lot.
    Put some patches and apply menuconfig to select enable/disable it.
Anything is good. This one, Buildroot can help a lot.
2. Some binary code/source code from vendor/SDK. This one is familiar to
open source, we don't need to change a lot, too.
    Follow SDK instructions and apply patch to Buildroot is enough to get
anything done.
3. Source code from our side, this part we change a lot and we would like
to build it at source folder because
    A. We change git log at source folder, we can trace anything quickly,
don't need to switch folder to build.
    B. We can build one source code instead of check anything, it is faster
to build(makefile check dependency) and install into fakeroot folder to try.
    C. We won't forget to commit the code, because any operations at source
folder.

I believe buildroot is the best for small embedded system, and we would
like to try if we can get item 3 done in our project.
I hope anything is clear. Thanks.

Sorry but I don't see why using the proposed <pkg>_OVERRIDE_SRCDIR
will solve the things you want to achieve in item 3.
