[Buildroot] Source download overwrite

[Buildroot] Source download overwrite

[Mathieu Slabbinck]

Hi,

I'm looking for a way to overwrite the internal download system of buidroot
for a specific homebrew package.

The goal of the package is to download multiple files and install them
accordingly.
LIBFOO_SITE contains the common part of the download link. For example
ftp://myftpserver.mydomain.com/libfoo/.

Then I'd like to have a pre-install hook that downloads some specific files
from that url, for example
- ftp://myftpserver.mydomain.com/libfoo/file1.deb
- ftp://myftpserver.mydomain.com/libfoo/file2.rpm
- ftp://myftpserver.mydomain.com/libfoo/file3.someExtension

This all works fine, but the package still tries to fetch
ftp://myftpserver.mydomain.com/libfoo/.tar.gz because of the internal way
of working of buildroot.

So how can I overwrite this method or disable it?

Kind regards,

Mathieu

Why don't you simply use the <pkg>_EXTRA_DOWNLOADS variable? It allows
you to download additional files from the same site, which seems to be
exactly what you're trying to achieve.

LIBFOO_SITE = ftp://myftpserver.mydomain.com/libfoo/
LIBFOO_SOURCE = <one file>
LIBFOO_EXTRA_DOWNLOADS = <another file> <yet another file>

Best regards,

Thomas

Thomas,

thanks for pointing this out. Was looking for this kind of variable but
didn't really find any docs about it.
Managed to get it working now.

Thanks!

Mathieu

I just checked, and at
http://buildroot.org/downloads/manual/manual.html#_infrastructure_for_packages_with_specific_build_systems,
under the section "16.5.2. generic-package reference", we do document
the EXTRA_DOWNLOADS variable:

"""
LIBFOO_EXTRA_DOWNLOADS lists a number of additional files that
Buildroot should download from LIBFOO_SITE in addition to the main
LIBFOO_SOURCE (which usually is a tarball). Buildroot will not do
anything with those additional files, except download files: it will be
up to the package recipe to use them from $(BR2_DL_DIR).
"""

Though I agree the manual is now very long, and it is easy to overlook
certain possibilities provided by Buildroot.

Cool!
