Trying to build on cygwin 32bit

[txdv]

I am trying to build the gem on a Windows 7 64bit, cygwin 32bit system, ruby 2.2.4p230 (2015-12-16 revision 53155) [i386-cygwin], I downloaded the 10.2.0.5.0 basic, sdk and sqlplus packages, I got around a few errors, but I'm hitting a wall with OCIEnvCreate:

--------------------

It just cant find OCIEnvCreate, although it is defined in the oci.h:

#define OCIEnvCreate               ocienvct

Maybe it doesn't find the pointer first because it is a define? The other time the amount of arugments is just not right os it just fails.

Any insights on the error and how I can circumvent it?

Could you check OCI.def created by oraconf.rb whether it includes OCIEnvCreate?

I got around a few errors

What errors did you get around? It might be, perhaps, important.

After you get around the OCIEnvCreate issue, you will hit a next wall reported by #113.
You need to replace three files in the trunk.

• ext/oci8/oraconf.rb
• ext/oci8/extconf.rb
• ext/oci8/plthook_win32.c
