[oe] apache2+php5 on Arago

Wed Feb 23 13:34:02 UTC 2011

Hi,I've investigated a bit more on the topic apache2/modphp not working (segmentation fault) on Arago.During the resume I'm going to write, I will need to underline some aspects concerning the toolchain and the corresponding glibc packages.Then, from the beginning:apache2_2.2.14 + modphp_5.1.6 (libphp5 module loaded by LoadModule directive inside httpd.conf) are unusable in my Arago DISTRO 2010.12 cross-compiled with CodeSourcery2009q1 (apache2 segfaults).If I commented out the LoadModule directive from httpd.conf file and I restart httpd, apache2 works but obviously cannot access php pages.Since my filesystem was built starting from Arago, an external toolchain was used (CodeSourcery2009q1 and its corresponding "glibc packages" with version 2.8).If I had used CodeSourcery2010q1, I would have got "glibc packages" with version 2.11.1.Since some people of OE mailing list (Raffaele and Marco) told me some days ago that they were able to make apache2 fully work in a "pure" OE environment (not Arago overlay), I downloaded from git repositories the OE release 2010.12 and I tried to understand how to use an external toolchain to achieve apache2 and modphp ipk packages.I made so because my intention was to produce these two packages and test them inside the Arago filesystem previously described.When the ipks were ready (cross compiled against glibc-2.8) I tested them on the beagleboard with Arago2010.12 (CS2009q1 and glibc-2.8).Apache2 works without loading php5 module (only html pages), segfaults when libphp5 is loaded.Then exactly the same behaviour as in Arago.
Probably Marco and Raffaele were using an OE filesystem built with "internal" toolchain (then glibc-2.9 instead than 2.8)?Can you confirm this?About this, now I'm trying to build an OE minimal-image for beagleboard where apache2 and modphp are inserted as additional packages (I edited minimal-image.bb).This time I'm using the "internal" toolchain (then glibc-2.9.bb will be used this time).However I already know that these packages, even if working in the minimal-image filesystem, will be unusable inside my Arago with glibc-2.8 (glibc mismatch).I'll let you know if I have some interesting news.In the meantime I hope to receive some opinions of yours.
Bye,Luca

Luca,
unfortunately for you, I can only confirm that Apache2+php5 work with a
charm on our customers' ARM9 devices using KaeilOS/Openembedded (not Arago).

Cordiali Saluti / Kindest Regards / mit freundlichen Grüssen
