I can change sc.ini to get everything to build. I can compile with dmd myapp.d -I -c, but I can't seem to figure out the right switches to make the app find the ociliba-dm.lib that I generated. Using sc.ini seems to work, using the lib environment variable seems to work but I'd like to understand how to make the command line switches work. The compiled application hangs the first time it calls an ocilib routine and I don't expect you folks to debug that for me but it occurred to me that since I have the paid-for version of dmc I could try essentially the same code vs. c++ and if it worked that would isolate the problem to the ocilib.d header. I have the same "can't find the library with command line switches" problem but I suspect the D fix will help me c++-wise as well. The unique to c++ issue is shows like so. C:\ocilib\ocilib3.9.3\lib32>dmc myapp.cpp -c -Ic:\ocilib\ocilib3.9.3\include C:\ocilib\ocilib3.9.3\lib32>optlink myapp.obj,,,ociliba-dm.lib OPTLINK (R) for Win32 Release 7.50B1 Copyright (C) Digital Mars 1989 - 2001 All Rights Reserved myapp.obj(myapp) Error 42: Symbol Undefined _OCI_Cleanup myapp.obj(myapp) Error 42: Symbol Undefined _OCI_GetString ... 7 more, covering all ocilib calls. running lib -l vs. ociliba-dm.lib shows symbols with @ signs appended, e.g. _OCI_Cleanup@0 and _OCI_GetString@8. I suspect there's some simple disconnect on my part here, but I can't see it. Any assistance deeply appreciated. Please try adding `-DOCI_API=__stdcall -DOCI_CHARSET_ANSI` to dmc command line. (check http://orclib.sourceforge.net/doc/html/group__g__install.html) If you get runtime errors, please check your ORACLE_HOME environment variable and make sure your %ORACLE_HOME%\bin directory is in your PATH environment variable.

Thanks for the help. All I did was generate a OMF library running IMPLIB vs. OCILIBA.DLL. I think your suggestion involves building OCILIB from scratch. Is that right? Rebuilding the library looks like a job and I want to make sure that's what I need to do to proceed.

No. You should add '-DOCI_API=__stdcall -DOCI_CHARSET_ANSI' to dmc when building your c/cpp app. Rebuilding the library looks like a job and I want to make sure that's what I need to do to proceed.
