[Buildroot] Open bug overview: help wanted!

Thomas, All,

On 2014-07-12 20:50 +0200, Thomas De Schampheleire spake thusly:

Thanks for this summary! :-)

Well, those patches are huge, and they touch very critical pieces of
gcc. I would mark musl support broken and remove the patches, until the
patches are fixed.

Unfortunately, that's already been part of a release, so we can't
silently hide it... :-(

No release, no mipseb support. The submitter should press the jamvm
maintainer to do a release.

I'm not a fan of all this rpath trickery.

Basically, the submitter (probably) wants this to run his
buildroot-built system from somewhere else than / and does not want to
chroot into it.

Should we add complexity to Buildroot for this use-case?

This one is indeed a bit tricky. I looked at what the Xenomai guys said:

---8<---
Xenomai does not do anything special, it uses the autotools default
which is:
- if you pass CFLAGS and LDFLAGS on the right hand of the configure
command line, the generated makefiles are hardcoded with these flags
values, and you need not do anything special later on to get these flags
used for all the compilations. This has been the recommended way of
passing CFLAGS and LDFLAGS when building autotools-based projects for
many years.

- if you want to pass them as environment variables (so, on the left
hand of the configure command line), the makefiles are not generated
with these flags, so, you have to pass them in the environment of the
"make" command.
---8<---

Which indeed makes sense. And we do pass them as environment variables
in package/pkg-autotools:

    [...]
    $$(TARGET_CONFIGURE_OPTS) \
    $$(TARGET_CONFIGURE_ARGS) \
    $$($$(PKG)_CONF_ENV) \
    ./configure \
    [...]

So we should probably pass them after ./configure, i.e. on the right-hand
side of ./configure.

I can have a look...

ARM noMMU is basically broken, as Gustavo said in a comment.

Should be closed, the patch has been applied:
    http://git.buildroot.org/buildroot/commit/package/thrift?id=1aaa14d84f1c920423ed0286b78f64a2b4b2b575

New packages should be posted to the list.

For those two, the packages are disabled because of an ICE. WE can't do
much more than disabling the packages. Which is already done. Close
those bugs?

Patches on the list.

I can have a look.
