You need to pass a path to the CLI driver (see heading - download it, extract it somewhere) w/ the --with-IBM_DB2= flag, i.e. ``--with-IBM_DB2=/opt/clidriver. I don't use the pecl` frontend, so I don't know how to pass those flags when using it.

[MaraRuizG]

Hi, I had already passed this path to the CLI driver before
IBM_DB_HOME=/opt/ibm/clidriver
LD_LIBRARY_PATH=/opt/ibm/clidriver/lib
and still had the error
I also tried what you suggested
pecl install ibm_db2 --with-IBM_DB2=/opt/ibm/clidriver
but I'm getting the same error

/usr/bin/ld: skipping incompatible /opt/ibm/clidriver/lib//libdb2.so when searching for -ldb2

The linker seems to think it's incompatible. Did you download the correct driver for the architecture you're building?

[MaraRuizG]

I think so.
I'm using a mac with chip M1 and the driver is 64-bit.

[kadler]

Well, first I don't think they support ARM yet: https://github.com/ibmdb/python-ibmdb/tree/master/IBM_DB/ibm_db#-client-license-for-specific-platform-and-architecture

And downloading the public client from the FTP site shows no:

$ file libdb2.dylib
libdb2.dylib: Mach-O 64-bit dynamically linked shared library x86_64

However, I just realized you're running Docker so none of that matters since the Docker container is Linux and indeed the error message references libdb2.so, not libdb2.dylib.

Apparently Docker for Mac can build and run both x86 and ARM images: https://www.docker.com/press-release/Docker-Desktop-for-M1-powered-Macs

Docker has long supported multi-platform container images with the ability to build and run both x86 and Arm images on Docker Desktop. With this release, developers can build and run end-to-end on the Arm architecture from Docker Desktop on their M1-powered Macs to Arm-based cloud servers such as AWS Graviton 2.

My guess is it defaults to an ARM image, but you'll need to figure out a way to have Docker build an x86 image instead.

@MaraRuizG were you able to resolve this ?
