[Buildroot] User-space packages - Staging_Dir or Target_Dir

[Daniel Frey]

Do I need to explicitly copy what I install into the staging dir into the
root dir in order for the new libraries to be included in the resulting
image?

I have seen this done in the xml2 makefile and I wasn't sure if it was
needed for every package.

[Buildroot] User-space packages - Staging_Dir or Target_Dir

[Thiago A. Corrêa]

yes, some packages will instead use make install with the appropriate
DESTDIR set or having configured it with the prefix. But most of the
time, make install does stuff you don't want, like install man pages.
One has to check what the package makefiles are doing to make sure.

I handle it like this:
staging_dir contains non-stripped stuff.
If a file is needed on the target, it has to be copied to the target.
That copy (in target_dir) is then (eventually) stripped.
This provides for easy debugging in the staging_dir since those contain
debug-info.

It is not needed for every package.
Think about tcpdump/libpcap. Consider how you don't want libpcap on your
target if the only app that is using it is tcpdump anyway. You would
rather link tcpdump against libpcap.a and only install tcpdump to the
target.

[Buildroot] User-space packages - Staging_Dir or Target_Dir

[Daniel Frey]

When constructing my make files for my packages in the package/, what is the
suggested installation directory, TARGET_DIR or STAGING_DIR?

Some of the included packages install them to STAGING_DIR.  The
Documentation on the buildroot website has them installed in the TARGET_DIR.

Is there a correct way, or preferred way?

Thanks.

Depends :)

Files that go straight to the target have to me installed to the
TARGET_DIR. Intermediate files (prerequisites of stuff that will be on
the target like helper libraries, headers, etc) have to live in
STAGING_DIR. Sometimes only a small fraction of files in the staging_dir
is needed in the real target, so they are copied selectively.

HTH,
Bernhard
