Unable to load dynamic library 'oci8.so' (PHP 7.2)

Since the update of PHP 7.1 to PHP 7.2 I can't install oci8. I have this error:

root@3ab6027c8d95:/var/www# php -v

PHP Warning: PHP Startup: Unable to load dynamic library 'oci8.so' (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so (libmql1.so: cannot open shared object file: No such file or directory), /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so.so (/usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

I'm using Docker environment, I created a github repo for this, it works if I use the version 7.1 of PHP (shenron/docker-php-fpm:7.2).

I don't understand why the script try to launch this file: /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so.so.

To my point of view there are two possibilities; or the driver is not compatible, or pecl can't today install oci8.

Has anyone the same problem ?

Thank you for your help.

/usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so.so is only the second guess on the shared library file name. You can safely ignore that.

The actual problem is: (tried: /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so (libmql1.so: cannot open shared object file: No such file or directory)

oci8.so itself depends on multiple shared libraries, you can use ldd to find out which ones:

ldd /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so
    linux-vdso.so.1 (0x00007ffc8bfe7000)
    libclntsh.so.12.1 => /usr/local/instantclient/libclntsh.so.12.1 (0x00007fb9919e0000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb991641000)
    libmql1.so => not found
    libipc1.so => not found
    libnnz12.so => not found
    libons.so => not found
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fb99143d000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fb991139000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb990f1c000)
    libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007fb990d04000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fb990afc000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fb994bc8000)
    libaio.so.1 => /lib/x86_64-linux-gnu/libaio.so.1 (0x00007fb9908fa000)
    libclntshcore.so.12.1 => not found

Those .so files seem to be part of a zip file in your repository. Running PHP like this LD_LIBRARY_PATH=/usr/local/instantclient_12_1/ php works fine inside your container. You need to move those so files to a sane location.

For anyone stumbling upon this question, here is the proper way to handle it in linux. (I am using CentOS commands for the demo below but Ubnutu shouldn't be any different)

step 1: get oracle libs

EDIT: Thanks to Christopher Jones for the comment, you can find the direct rpm links at https://yum.oracle.com/repo/OracleLinux/OL7/oracle/instantclient/x86_64/

wget oracle-instantclient18.3-basic-18.3.0.0.0-1.x86_64.rpm 
wget oracle-instantclient18.3-devel-18.3.0.0.0-1.x86_64.rpm

step 2: install

yum install oracle-instantclient18.3-basic-18.3.0.0.0-1.x86_64.rpm
yum install  oracle-instantclient18.3-devel-18.3.0.0.0-1.x86_64.rpm

step 3: configure (make the path of the oracle libs to be discoverable)

sudo sh -c "echo /usr/lib/oracle/18.3/client64/lib > /etc/ld.so.conf.d/oracle.conf"
sudo ldconfig

test

php -v
# and you should get something like
PHP 7.2.12 (cli) (built: Nov  6 2018 16:40:25)...

If running ldd /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so gives you something like this, with missing files:

ldd /usr/local/lib/php/extensions/no-debug-non-zts-20170718/oci8.so
    linux-vdso.so.1 (0x00007ffc8bfe7000)
    libclntsh.so.12.1 => /usr/local/instantclient/libclntsh.so.12.1 (0x00007fb9919e0000)
    libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb991641000)
    libmql1.so => not found
    libipc1.so => not found
    libnnz12.so => not found
    libons.so => not found
    libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fb99143d000)
    libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007fb991139000)
    libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb990f1c000)
    libnsl.so.1 => /lib/x86_64-linux-gnu/libnsl.so.1 (0x00007fb990d04000)
    librt.so.1 => /lib/x86_64-linux-gnu/librt.so.1 (0x00007fb990afc000)
    /lib64/ld-linux-x86-64.so.2 (0x00007fb994bc8000)
    libaio.so.1 => /lib/x86_64-linux-gnu/libaio.so.1 (0x00007fb9908fa000)
    libclntshcore.so.12.1 => not found

You can add the folder to your ldconfig like this (other readers - your path may vary):

echo /usr/local/instantclient_12_1/ > /etc/ld.so.conf.d/oracle-instantclient.conf

Then run ldconfig to read the new config.
