PHP Warning: PHP Startup: Unable to load dynamic library 'pdo_snowflake.so'

[alex.sanzharovskiy]

Hello!
I'm trying to add pdo_snowflake extension in my php 7.4.25.
What I'm using:

1. Centos 7
2. PHP 7.4.25

What I did:

export PHP_HOME=/usr
 git clone https://github.com/snowflakedb/pdo_snowflake.git
cd pdo_snowflake
./scripts/build_pdo_snowflake.sh

-----------> Result:

build complete.
Don't forget to run 'make test'.

Linking for Linux
libtool: install: cp ./.libs/pdo_snowflake.so /opt/pdo_snowflake/modules/pdo_snowflake.so
libtool: install: cp ./.libs/pdo_snowflake.lai /opt/pdo_snowflake/modules/pdo_snowflake.la
libtool: finish: PATH="/usr/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/sbin" ldconfig -n /opt/pdo_snowflake/modules
----------------------------------------------------------------------
Libraries have been installed in:
   /opt/pdo_snowflake/modules

If you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the `-LLIBDIR'
flag during linking and do at least one of the following:
   - add LIBDIR to the `LD_LIBRARY_PATH' environment variable
     during execution
   - add LIBDIR to the `LD_RUN_PATH' environment variable
     during linking
   - use the `-Wl,-rpath -Wl,LIBDIR' linker flag
   - have your system administrator add LIBDIR to `/etc/ld.so.conf'

See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

And then after this command:

$PHP_HOME/bin/php -dextension=modules/pdo_snowflake.so -m | grep pdo_snowflake

I've got this response:

PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_snowflake.so' (tried: /usr/lib64/php/modules/pdo_snowflake.so (/usr/lib64/php/modules/pdo_snowflake.so: undefined symbol: _ZTVNSt7__cxx1118basic_stringstreamIcSt11char_traitsIcESaIcEEE), /usr/lib64/php/modules/pdo_snowflake.so.so (/usr/lib64/php/modules/pdo_snowflake.so.so: cannot open shared object file: No such file or directory)) in Unknown on line 0

And even when I'm creating file: 20-pdo_snowflake.ini
With content:
extension=pdo_snowflake.so
pdo_snowflake.cacert=/etc/php.d/cacert.pem

cp modules/pdo_snowflake.so /usr/lib64/php/modules/
cp libsnowflakeclient/cacert.pem /etc/php.d/cacert.pem

I have this issue:

$ php -v

Hi!
Today I've also had same issue. Simply change command to:
$PHP_HOME/bin/php -dextension=modules/pdo_snowflake.so -m | grep pdo_snowflake

Because if you would check command response there is double .so.

I've had this issue with Centos 7 but I think it ended up being that the gcc version available on yum is not high enough for what the driver needs.

I am also running into the same module not found issue on RHEL 8. Cloning the v.1.1.0 tag fixed it for me
