PHP startup errors with added modules

Hello,
i'm on master r13583 (based on hnyman's build)
i installed nginx, and it works good
then i added php7-fpm, and also this is working, with default config.
The problems come when i try adding some modules.
I have now this startup error adding the DOM pagkage

<b>Warning</b>:  Cannot load module 'xml' because required module 'libxml' is not loaded in <b>Unknown</b> on line <b>0</b><br />

and i have no idea where this comes from and how to debug this further.. any help?

the content of the lib folder is this:

/usr/lib/php# ls
curl.so      dom.so       gd.so        mbstring.so  pdo.so       sqlite3.so   xml.so       zip.so

thanks

i just upgraded to SNAPSHOT r14522, hoping this would fix something.
nothing, still all broken with added modules.
am i missing something? anyone using php modules with success?
thanks

hello again,
so i tried to get thos modules already built inside the image.
i get an error when i try to add the DOM module to my image, and the error is:

configure: error: DOM extension requires LIBXML extension, add --with-libxml

now, the libxml2 is SELECTED
i also tried adding php7 mods:

  • xml
  • simplexml
  • xmlreader
  • xmlwriter

same error always

then i tried adding a "different" php than the FPM i use and.. magic, a new menu item for libxml appeared
i don't know if this is correct, but it seams to work. probably also php-fpm should trigger the libxml menu..
but now, started back the system, opkg shows me only the already installed php packages and nothing more
why the hell??

However, I don't think that OpenWrt is a good choice for web-hosting/development.
You should be able to achieve your goal much simpler with a general-purpose distribution.
Use virtualization if there's no suitable hardware to install/run it.

hello,
i'm just testing it since it is supported.. why not?
but this does not explain why i can't have libxml with php7-fpm (if not changing makefile, ok)
or why i can no more see php packages in opkg.. probably i should report directly in github :slight_smile:

maybe your out of space or other disk-path issue... the packages are ok here (snapshot) and the error on your top post is a common one... ( been around for 1year + ) when php.ini is not setup right...

that said... i've never used fpm but i'm doubting that's the issue...

Just guessing: http://buildbot.openwrt.org/master/packages/builders/arm_cortex-a15_neon-vfpv4/builds/359/steps/compile/logs/stdio shows some php7 related build errors.

Well, there is a difference in the level of support.
It may be supported mostly in name but not in fact.

Probably that is the cause of the issue.
Or, it is expected that you should rebuild it with explicitly enabled CONFIG_PHP7_LIBXML.

so, summing up:

  • to have libxml, you can't have just php7-fpm, you also need to take cgi or cli (i got cli) and select the libxml option
  • this done, all the modules built work flawlessly
  • i have not understood why i can no longer see any php7-mod package. @tmomas do you mean their build could have failed for everyone? i just used them yesterday.. i'll wait tomorrow..

thanks all, next fight will be installing flask-ask under python :slight_smile:

they showed back up today..
