[cdt-dev] Add a custom toolchain to the Autotools CDT plugin

[Mélanie Bats <melanie.bats@xxxxxxx>]

Hello,

I am developing an Eclipse plugin[1] which integrate cross-compilation 
toolchains generated with Buildroot[2].

I already integrate successfully the toolchain to the CDT 
executable/shared libraries/static libraries build artefact types.
To do this, I contribute a new project type which refers to the 
org.eclipse.cdt.build.core.buildArtefactType.exe/shareLib/staticLib 
build artefact type (see the attached exe_plugin.xml). As we can see on 
the screenshot [3], in this case I got exactly what I expect, my 
toolchain is contributed to the "Executable" build artefact type. Of 
course, the provided exe_plugin.xml is just a minimal example that 
allows the toolchain to appear, our real code further customizes the 
toolchain for our needs, but this is beyond the scope of this e-mail.

Now I am trying to integrate my toolchain to the autotools build 
artefact type (because we want for example to set a default value for 
the --host= argument for our toolchain).

I contribute in the same way my toolchain (see the attached 
autotools_plugin.xml) but this time to the 
org.eclipse.linuxtools.cdt.autotools.core.buildArtefactType.autotools 
build artefact type.

If we have a look to the second screenshot [4], we can see that my 
toolchain is not contributed under the "GNU Autotools" and a second "GNU 
Autotools" section shows up in the wizard, but this second section is empty.

Does someone can explain to me how to contribute a cross compiled 
toolchain to the Autotools build artefact type thanks to the managed 
builder build definitions extension point?

Thanks for your help,
Mélanie

PS: As I saw that Jeff Johnston was contributing the Autotools plugin to 
the CDT project I add him as cc to this email.
