[gentoo-embedded] CFLAGS and binutils

Hi vapier,

in Bug http://bugs.gentoo.org/show_bug.cgi?id=149398 you said, that
I'm mistaken with CFLAGs in the role of cross-compilers.

OK, describing what I want:

I have two directories

ROOT=/usr/powerpc-softfloat-linux-uclibc (This is, where the toolchain
did go)
PORTAGE_CONFIGROOT=/var/ppceb

in /var/ppceb/etc/make.conf
CFLAGS="-Os -mcpu=405 -mtune=405 -fomit-frame-pointer -pipe"
CHOST="powerpc-softfloat-linux-uclibc"
CBUILD="i686-pc-linux-gnu"
CTARGET="powerpc-softfloat-linux-uclibc"

ACCEPT_KEYWORDS="-* ppc"

when I do a
ROOT="..so.." PORTAGE_CONFIGROOT="..so.." emerge binutils


It compiles some things with i686-pc-linux-gnu, where the problem
comes up, that it crashes, because gcc doesn't know -mcpu=405 and
- -mtune=405

You said before, that everything regarding libs should go there...
Tell me if I'm wrong, but when I put everything there and strip down
everything later or do a later emerge on the needed packages to
another ROOT, everything should be fine.

[gentoo-embedded] apache on gnap (problems with apr-util)

[Janusz Syrytczyk]

Hi,

I would like to have apache web server with php module on my GNAP system, but 
while compiling apr-util (dependency required by apache) I have error saying 
the apr-util package is masked, even though I tried unmasking it in 
myspecs/portage_confdir/ portage.keywords.

I have found that commenting out the line:

inherit eutils flag-o-matic libtool db-use

in apr-util-0.9.12.ebuild results in unmasking the package but later it fails 
because of: catalyst error : <unprintable instance object>" . And I 
understand that changing an ebuild may result in unprediceable errors so I 
kindly ask if there is any other stright way to have apache correctly 
compiled on gnap? I did modify portage tree by adding arbitrary packages of 
course.

How it is exactly masked? There are many different ways to mask
something. When you try to emerge it, portage tells you something like

- - something/somepackage (masked by: missing keyword)

The round brackets at the end of this line tells you, why it can't be
merged. There are differnt kind of masks. One possibility is the
profile. If something is masked by profile, you only have the ability
to change the link in etc/make.profile to get out of this.
Perhaps in your case it can be done with
echo "something/somepackage" >> /etc/portage/package.unmask

This is bad!

Make everything as it was and post the output of emerge. Then it's
easier to help you. Perhaps also add emerge --info

apache on embedded? You might have your reasons for that, but there are
many good alternatives:

mini_httpd
lighttpd
appWeb (https://bugs.gentoo.org/show_bug.cgi?id=145073)

I run subersion (also requires apr- stuff) on uclibc hardened. No
problems.

I Don't use apache though.

Hi,
I've already put >=dev-libs/apr-util in package.unmask and also tested 
with ~x86 flag in package.keywords. I'm familiar with portage and is 
configuration, but gnap/Catalyst gives slightly another output and has 
slightly different rules.

Well... I'm sure that could make very nasty things, and I surely won't 
go with this, that was just a test.   Anyway,  is this the line which 
delivers extra parameters which tells the gnap/catalyst that package is 
masked, isn't it?

Everything looks good for me, except that gnap/Catalyst perceives 
apr-util as masked although it should not. My gnap output is:

While this occurs, I have:

net-www/apache ~x86

Other files are gnap standard. I do not have anything special changed in 
relation to base system. And I make extensions using right 
portage.tar.bz2 and myspecs, I managed to do a few gnap based devices 
before ;-)
