[Buildroot] ipv6 and eglibc

[Buildroot] ipv6 and eglibc

[Marco Trapanese]

Hello,
I'm trying to add the postgres package, starting with this hints:

http://www.slideshare.net/jerome42/create-lightweight-docker-containers-with-buildroot

I'm using the eglibc in order to enable the eglsf support for Qt5.
Postgresql requires the BR2_TOOLCHAIN_BUILDROOT_INET_IPV6.

Searching for this keyword I see this:

Symbol: BR2_TOOLCHAIN_BUILDROOT_INET_IPV6 [=n] ?
Type : boolean
Prompt: Enable IPv6 support
Location:
-> Toolchain
Defined at package/uclibc/Config.in:70
Depends on: BR2_TOOLCHAIN_BUILDROOT [=y] && 
BR2_TOOLCHAIN_BUILDROOT_UCLIBC [=n]
Selects: BR2_INET_IPV6 [=y] ?

I guess because I'm using eglibc instead of uclibc.

I have no knowledge to decide what I should do now....
Thank you for your support!
Marco

This is because what J?r?me (who happens to be my cousin) did was
not completely correct (and I've Cc'ed J?r?me so he gets this
feedback!).

Having a dependency on BR2_TOOLCHAIN_BUILDROOT_INET_IPV6 in a package
is incorrect, as it only works with the internal toolchain backend,
when building uClibc toolchains.

Instead, he should have read the great Buildroot documentation at
http://buildroot.org/downloads/manual/manual.html#dependencies-target-toolchain-options :-)

So, Marco, just modify the line:

	depends on BR2_TOOLCHAIN_BUILDROOT_INET_IPV6

by:

	depends on BR2_INET_IPV6

Also, please submit patches to add Postgresql support. Instead of
having people following the not-completely correct tutorial of J?r?me,
we would have Postgresql support in Buildroot itself.

Thanks!

Dear Thomas Petazzoni,
thank you for you kind and fast answer.
I'll submit the patch (after checked it works ;-) )

Best Regards
Marco

Thomas,
here my current package files of postres:

Config.in
config BR2_PACKAGE_POSTGRES
     bool "postgres"
     depends on BR2_INET_IPV6
     help
      Postgres SQL server

comment "postgres requires a toolchain with IPV6 support enabled"
     depends on !BR2_INET_IPV6

postgres.mk
POSTGRES_VERSION=9.3.2
POSTGRES_SOURCE=postgresql-$(POSTGRES_VERSION).tar.gz
POSTGRES_SITE=http://ftp.postgresql.org/pub/source/v$(POSTGRES_VERSION)/($POSTGRES_SOURCE)
POSTGRES_CONF_OPT=--with-system-tzdata=/usr/share/zoneinfo
POSTGRES_DEPENDENCIES=readline zlib

$(eval $(autotool-package))


I added the source item in the main Config.in and I selected the 
"postgres" package in the nconfig menu.
However, I can't see any reference to it neither in the Makefile nor in 
the build directory (of course after a make clean all cycle).

I read the guide at the autotools-based packages but it seems it doesn't 
try at all to download and compile it. What should I check to be sure 
buildroot understand it has to?

By the way my .config file contains the following:

BR2_PACKAGE_POSTGRES=y


Thanks!
Marco

This comment does not comply with the standard practices. See
http://buildroot.org/downloads/manual/manual.html#dependencies-target-toolchain-options.

This should be autotools-package. Make sure you read the Buildroot
manual carefully, section
http://buildroot.org/downloads/manual/manual.html#_infrastructure_for_autotools_based_packages.

See above, you made a small typo when calling the autotools-package
macro.
