Hi to all,

I'm actually evaluating Debenu (foxit quick) PDF SDK. I need to integrate inside a PHP project on Linux.

I am actually trying to get a working extension with php-cpp. I'm wondering if anybody has some working procedure or example for it?

thanks,

Michele

Hi to all,

I was able to successfully compile the extension... but unfortunately calling it does segfaults. Anyway, here is my procedure.

Linux: CentOS Linux release 7.5.1804 (Core)

== PHP-CPP: 2.2.0 ==

Downloaded: make, make install. This putted /usr/lib/libphpcpp.so

Tested libphpcpp with example 'simple' inside PHP-CPP package. This worked.

== Foxit ==

Copied the simple example.

main.cpp overwritten with Import/PHP/FoxitQPLLinuxMain1811.cpp from foxit devel zip.

Makefile modified in the relevant part:

COMPILER_FLAGS = -Wall -c -O2 -std=c++11 -fpic -o

LINKER_FLAGS = -shared

LINKER_DEPENDENCIES = -lphpcpp -lQPLLinux

This produces: foxitquickpdf.so

It seems linked correctly: ldd foxitquickpdf.so

linux-vdso.so.1 => (0x00007ffd5891d000)

libphpcpp.so.2.2 => /lib/libphpcpp.so.2.2 (0x00007f2d009d6000)

libQPLLinux.so => /lib/libQPLLinux.so (0x00007f2cff738000)

libstdc++.so.6 => /lib64/libstdc++.so.6 (0x00007f2cff431000)

libm.so.6 => /lib64/libm.so.6 (0x00007f2cff12f000)

libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f2cfef19000)

libc.so.6 => /lib64/libc.so.6 (0x00007f2cfeb4c000)

/lib64/ld-linux-x86-64.so.2 (0x00007f2d00c80000)

libdl.so.2 => /lib64/libdl.so.2 (0x00007f2cfe948000)

/usr/lib/libQPLLinux.so -> /usr/lib/libFoxitQPL1811-linux-x64.so from foxit devel zip.

The trying with:

<?php

$QP = new FoxitQPL();

$k = $QP->Unlocked();

echo $k;

but it segfaults.

Any ideas?

thanks

Hi Michi,

do you have a testkey or regkey from Debenu/Foxit tounlock the library?

Hi Ingo,

Yet I have a trial key. I also tried putting

$k = $QP->UnlockKey("jz45q97d5ap8ut6w77nr9rb8y");

but it also segfaults. Also var_dump($QP) segfaults.

I think it's something relate to linking with Foxit provided .so lib for linux. I've noticed that even if I not specify -lQPLlinux as a linker option it gets compiled straight away... but how it could be so without reference to the .so library provided by Foxit?

I noticed a warning:

[31-Aug-2020 23:14:50 UTC] PHP Warning: Module 'qplphp' already loaded in Unknown on line 0

And here my backtrace:

Here on the forum someone is able to contact developers inside Foxit Debenu team?

Hi,

Just another matter of facts. I know notice that my license file, received on 29 august, says "valid until 21 aug 2020'. what????? I really start wondering if Foxit Quick pdf library is a real alternative to Foxit full...

"...

..."

This here is a user-community which has less to do with Debenu/Foxit.
So there's no direct contact to the developers.

Here you should get the contact you need:
https://www.debenu.com/support/

Hi ingo,

Thanks so much for you help!

I wrote to the official foxit support too; waiting for some feedback.

I was wondering if - as usual elsewhere - some Foxit employee gives a sneak peak here...

regards,

Michele

Hi to all,

Foxit Software Support replied today. Thanks to Kevin N. I was able to obtain my first PDF! He fixed also my license number wrong expiration date.

To solve the segfault ... You need to pass the path to the .so library to the QPL constructor to make it work, in my case installed in /usr/lib:

$QP = new FoxitQPL('/usr/lib/libQPLLinux.so');

libQPLLinux.so is the name assigned by ldconfig.

Just wanted to let members know. I'm still not having much luck getting this installed on a Linux either on Centos and Ubuntu.

Hi Tex,

what does "segfaults" mean?
Google isn't able to translate it.
Don't know if it matters but you know that QP is handling strings as unicode?
