PHP 8.1.11 (phpenv) cannot find pdo_ibm.so on Ubuntu 20.04

[daniilly]

Package: PDO_IBM-1.5.0
Client: IBM Data Server Driver Package V11.5.4

1. We installed DB2 driver package by following the IBM instructions
2. At the start of installing PDO_ibm with PECL. We got an issue with the "include" directory path (the folder where we have header files). We solved this problem by setting an environment CPATH(export CPATH=[path to "include" directory in DB2 driver package folder])
3. Now we got an issue with finding pdo_ibm.so

Error message on step 2:

In file included from /tmp/pecl-build/PDO_IBM/PDO_IBM-1.5.0/pdo_ibm.c:31:
/tmp/pecl-build/PDO_IBM/PDO_IBM-1.5.0/php_pdo_ibm_int.h:26:10: fatal error: sqlcli1.h: No such file or directory

What's the command line you're running to start the build? Are you running phpize/configure directly, or are you using the pecl/pear tool? This looks like you're missing LDFLAGS that specify where libdb2.so lives, but I would think the configure step is supposed to sort that out.

[kadler]

I think the problem is with -Wl,-rpath -Wl,-soname -Wl,pdo_ibm.so. Those are gonna get passed to the linker as ld ... -rpath -soname pdo_ibm.so, but since no argument is specified for -rpath, the -soname argument will be interpreted as the RPATH, leaving a bare pdo_ibm.so which gets interpreted as a linker input. This matches with the pdo_ibm.so: No such file or directory error message.

Now the question is why is the -rpath not getting passed correctly?

[daniilly]

@NattyNarwhal, thanks for the answer

At first, we tried the command phpenv pecl PDO_IBM. After failing with the error stated above we use directly:

• phpize
• ./configure
• make

Here are the environmental constants that we set pre-driver installation:
LD_LIBRARY_PATH=/home/user/clidriver/lib
IBM_DB_HOME=/home/user/clidriver

@kadler, thanks for the answer

Can you point out the suspicious parts of the text above?

[NattyNarwhal]

This is definitely broken:

checking for DB2 driver for PDO... yes, shared
checking Looking for DB2 CLI libraries... checking      in yes... 
checking      in yes/lib64... 
checking      in yes/lib32... 
checking      in yes/lib... 
checking for DB2 CLI include files in default path... checking in yes... checking for PDO includes... /home/user/.phpenv/versions/8.1.11/include/php/ext
checking "/libdb400.a"... 

The search paths don't look right. You shouldn't be seeing anything about libdb400 when using LUW.

FWIW, the way I run ./configure is with the argument instead of the environment variable; i.e. ./configure --with-pdo-ibm=/home/calvin/opt/clidriver/. Does that work for you as a workaround?

[daniilly]

@NattyNarwhal, great thanks!

./configure --with-pdo-ibm=/home/user/clidriver worked for me. Everything is being built successfully.

Here is the difference from the previous part of the configure log (interesting that it's still looking for libdb400):

checking Looking for DB2 CLI libraries... checking      in /home/user/clidriver... 
checking      in /home/user/clidriver/lib64...

I'm reopening this because we should fix this. The checks seem pretty flaky.
