Buildroot: Build only one package as both shared a

buildroot offers to possibility to build

only static,
only shared,
or both shared and static libs

of the selected packages.

The assigned configuration elements are BR2_STATIC_LIBS, BR2_STATIC_LIBS, and BR2_SHARED_STATIC_LIBS.

Question:

Is it possible to build both a shared and static lib for one package only, while building only shared libs for all the other packages?

The one project which I want a static lib of would be an autotools-based package.

My effort:

I did read the manual, but to no avail. I did come up with one idea though, but I think it won't work: I could have buildroot call the configure script with some arguments defined by me forcing the additional creation of a static lib. However, this would collide with the arguments buildroot is providing, which are forcing configure to do quite the opposite. (Create shared lib only.)

Thank you!

Unfortunately I can't even tell which version of buildroot I am using, as I did not find a way to get buildroots version number.

Buildroot does not directly support changing options for one package only. That would simply explode the number of options.

The easiest way to do this is to edit package/foo/foo.mk and add the following line to it:

FOO_CONF_OPTS += --enable-static

These options come after the default autoconfig options (which contain --enable-shared --disable-static) and will thus override them.

If you don't want to touch the Buildroot sources, you can also do this in your local.mk or in a BR2_EXTERNAL -- see the manual for how to set these up.

The Buildroot version number is encoded at the top of the Makefile (line 90 in current master) in the variable BR2_VERSION. You can also look at the top of the generated .config file, which contains the version extended with the git commit hash.
