[Buildroot] [Question] Downgrade package application.

[Yu-Ting Kao]

Hi,

I have a patch for new feature on a package, but it works on lower
version. How can I build lower version in buildroot ? Are there any
menuconfig I can choose ?

No. For the vast majority of the packages, we only allow building a
single version, as we can't test all combinations of all package
versions.

So if you need a lower version than the one in Buildroot:

 1/ Short-term, you can just modify the .mk file, so that it uses
    whichever version you need.

 2/ Long-term, you should really upgrade to the latest version. If this
    latest version is causing issues for you, then work with the
    upstream project to fix them. Staying on an older version is
    definitely not a good idea.

Best regards,

Thomas

Dear Yu-Ting Kao,

i'm not sure i full understand, but:

First try to apply your patch on the current Buildroot tree, chances are
that it will apply. If it won't apply, it's always better to try to fix
the patch against the current version than using an old one.

If it's too complicated to fix the patch, as a final resolution, you can
either:
a) download an old tarball from https://buildroot.org/downloads/
or
b) clone the Buildroot git repository and use `git checkout <old git
hash value>' to go back in time.

For both of the options the best is if you know the version the patch
was created for (for example if you know when the patch was created, you
can use a version from that time or a bit earlier)


Good luck,
