How to build with 32-bit compatibility??

[VajiraPrabuddhaka]

In my linux pc I have already installed lampp. So when I build mongodb.so using this instructions, lampp suddenly says

"XAMPP is currently only availably as 32 bit application. Please use a 32 bit compatibility library for your system"

Can anyone help me to build this with 32-bit compatibility as it suggests??

It seems to e some generic error if PHP can't start. (https://shrinathsuccess.wordpress.com/tag/xampp-is-currently-only-availably-as-32-bit-application-please-use-a-32-bit-compatibility-library-for-your-system/) What does the following output:

/opt/lampp/bin/php -v

There is no problem building the MongoDB extension with a 32-bit PHP at all, but it is possible that you have to run export CFLAGS=-m32 before running ./configure

[VajiraPrabuddhaka]

@derickr I also done the CFLAGS=-m32 , but still it is not working

Here is the output for /opt/lampp/bin/php -v

PHP Warning: PHP Startup: Unable to load dynamic library '/opt/lampp/lib/php/extensions/no-debug-non-zts-20160303/mongodb.so' - /opt/lampp/lib/php/extensions/no-debug-non-zts-20160303/mongodb.so: wrong ELF class: ELFCLASS32 in Unknown on line 0

Heh. That is odd. It indicates it wants a 64-bit binary (ELFCLASS64) and not the ELFCLASS32 that you just built. Can you show the output of the following commands:

file /opt/lampp/bin/php
file /opt/lampp/lib/php/extensions/no-debug-non-zts-20160303/mongodb.so

[VajiraPrabuddhaka]

Now I changed to 64-bit and still getting initial error as in the first comment,

Followings are the outputs for titled commands:

file /opt/lampp/bin/php

/opt/lampp/bin/php: symbolic link to php-7.1.9

Can you step through the symlink and run file on the actual binary it points to?

[VajiraPrabuddhaka]

@jmikola it is pointed to php-7.1.9 binary file in the same directory, here are the details
Command: file /opt/lampp/bin/php-7.1.9

@VajiraPrabuddhaka Have you fixed this issue? I have the same error

[VajiraPrabuddhaka]

@flyneko No, I couldn't fix it, instead I turned to use global apache server installed in linux with global PHP installation for linux, rather than using lampp

[jmikola]

Closing this, given the OP worked around the issue by using a standard PHP installation. Ultimately, it seems this was a problem with LAMPP and not the driver's build process.
