checking for OCIEnvCreate() in oci.h... no on El Capitan

[seandilda]

I'm trying to install 2.2.1 on El Capitan.

I installed from homebrew and set OCI_DIR

The install errors with:

checking for cc... ok checking for gcc... yes checking for LP64... yes checking for sys/types.h... yes checking for ruby header... ok checking for OCIEnvCreate() in oci.h... no * extconf.rb failed * Could not create Makefile due to some reason, probably lack of necessary libraries and/or headers. Check the mkmf.log file for more details. You may need configuration options.

Checking mkmf.log, I see:

@seandilda Could you set the following environment variable and try again?

export MACOSX_DEPLOYMENT_TARGET=10.5

I googled and found this answer.

[seandilda]

And now my 'bundle update' works like a charm, thanks! I did reproduce the problem immediately before setting the variable, and confirmed that it breaks without the variable, but works with the variable.

I have the exact same issue (too few args to OCIEnvCreate) but exporting that environment variable doesn't help the issue with checking for OCIEnvCreate() in oci.h... no

I've tried it with libclntsh.dylib.12.1 and libclntsh.dylib.19.1. Running 11.5.1 Big Sur (have also tried the env variable with the new version too)

@allthesignals Could you open a new issue including exact error messages? I bet that your issue is unrelated to this. The key point of this issue is "couldn't understand kern.osversion `15.3.0'", not "too few arguments to function ‘OCIEnvCreate’".
