Installation of new NWRFCSDK does not work with sapnwrfc-0.19.

[Former Member]

Hi,

I was trying to install the new nwrfcsdk and the corresponding ruby sapnwrfc-0.19.

The rfsdk is located in D:\downloadmanager\mwrfcsdk (jsut unpacked it after download from service.sap.com and copied the dll into services32)

Unfortunately this does not work. Do I miss something ?

Any help is appreciated !

Here the errors I get:

I get errors on installation of the sapnwrfc-0.19 like:

We fixed our problem. We didn't have the environment variables set correctly.

And we learned a lot on the way. The most important learnings:

- compiling c-extensions on windows is not easy

- rbconfig.rb contains compilation specific commands, i.e. if ruby was compiled with mingw, VisualStudio or whatever. The idea is that extensions are compiled with the same compiler.

- this link contains a good recipe of what you have to do:

Hi,

I meet exactly the same problem than you when i try to install SAPNWRFC on my windows xp workstation. If i understood well, looks like everything works fine now. Could you explain a little bit more what you've done please ?

Thanks in advance for your help,

Hi

sorry, I did not see your question till now...

And because it has been quite a while ago, I don't remember any more details than what is described in the link. Are you still interested ? I could email you the resulting gem that we're still using.

Best regards

Adrian

Hi ,

I have tried with all combinations of slashes.

Unfortunately the error is the same.

Have you looked at the mkmf output - usually found in a file mkmf.log ?

[Former Member]

Hi - in your output it says that it can't find nwrfcsdk include+lib - also there seems to a mixture of forward and back slashes in the path. Hae you tried it with using forward slashes to denote the path?

On ubuntu linux 7.10:

If setup.rb seems to die with

"checking for sapnwrfc.h... no

adding default nwrfcsdk location for headers ...

checking for sapnwrfc.h... no

This will not work - ABORTING because cannot find sapnwrfc.h"

The problem is not that it cannot find sapnwrfc.h!

If you look in mkmf.log and see something like

"In file included from /usr/include/sapnwrfc.h:9,

from conftest.c:1:

/usr/include/sapuc.h:626:25: error: wchar.h: No such file or directory

/usr/include/sapuc.h:627:44: error: wctype.h: No such file or directory

/usr/include/sapuc.h:629:80: error: sys/types.h: No such file or directory

/usr/include/sapuc.h:630:24: error: dirent.h: No such file or directory"

Then you need to install the C standard headers:

sudo aptitude install libc6-dev

Hope this helps someone else...
