problem configure sapnwrfc

0 Kudos

Hi there,

I have successfully used php_saprfc.dll with WampServer 2.0b (Apache 2.2.8, PHP 5.2.5) on Windows server 2008. now I am upgrading to WampServer 3.1.4 (Apache 2.4.35, PHP 7.2.10) on Windows server 2016, the old php_safrfc.dll does not work anymore, so I am trying to use sapnwrfc. Building the sapnwrfc library from source is kind complicated for me, so I found some pre-built extensions for Windows (php_sapnwrfc-1.3.0-7.3.8-vc15-nts-x64.dll, php_sapnwrfc-1.3.0-7.3.8-vc15-nts-x86.dll, php_sapnwrfc-1.3.0-7.3.8-vc15-ts-x64.dll, php_sapnwrfc-1.3.0-7.3.8-vc15-ts-x86.dll, maybe not match my current PHP version, anyone can please provide a right version of prebuild extension? And also not sure if it’s the really issue, I also tried the newer wampsever which PHP is 7.3.12, does not work either). by some online information, seem I need the nwrfcsdk, so I got “nwrfcsdk_720” through our SAP technical guy, the following is how I trying to config it:

  1. I rename the prebuilt file "php_sapnwrfc-1.3.0-7.3.8-vc15-nts-x86.dll" to "php_sapnwrfc.dll", then copy it to "php\ext" folder. then update the php.ini file to have the extension set.
  2. copy the folder nwrfcsdk_720 to C driver, and rename it as "nwrfcsdk", then set environment PATH "C:\nwrfcsdk\lib",
  3. restart the windows server and apache server.

But the extension was not loaded, I check PHP log, here are the error:
[02-Jan-2020 21:53:03 UTC] PHP Warning: PHP Startup: Unable to load dynamic library 'sapnwrfc' (tried: c:/wamp/bin/php/php7.2.10/ext/sapnwrfc (The specified module could not be found.), c:/wamp/bin/php/php7.2.10/ext/php_sapnwrfc.dll (The specified module could not be found.)) in Unknown on line 0

What’s the problem here. Really hope someone help me on this to make it work.

Best regards,
