[ManuelMittler]

Hi there,

i was trying to install node-rfc but I get this errors:

Has someone an idea?

Thanks a lot in advance!

I had this issue. My problem was my path was not set correctly with the NWRFCSDK lib path. Described here

[bsrdjan]

Pre-compiled binary might not be available for your nodejs version. Which nodejs version are you using ?

The build from source should anyway work, with SAPNWRFC_HOME set to base folder of sapnwrfcsdk installed on your system (see my answer in #36).

[PrakashSadasivam]

I am facing the same issue installing on Linux with node.js 8.9.1 version.

Any idea? What am I missing?

[bsrdjan]

Pre-compiled binary is not available for 8.9.1, only the build from source.

[bsrdjan]

Just released 0.1.12 has 8.9 included and you may test in your system.

[PrakashSadasivam]

Thanks @bsrdjan.

[StefanScherer]

Awesome @bsrdjan, I tried to install on Windows, but still get 0.1.11 from npmjs.org

[bsrdjan]

Thank you very much @StefanScherer for catching this one. The version publish failed on npmjs, now should be fixed.

[StefanScherer]

@bsrdjan Thanks for the update. I've tried it with Node.js 8.9.1 on Windows, but during the installation I see this error:

Thank you Stefan, binary names should be fixed now. Please feel free to check.

I tried 0.1.12 in a Linux container, based on FROM node:6.12.0, but I get a shared library error

module.js:597
  return process.dlopen(module, path._makeLong(filename));

It works fine if I switch back to 0.1.11.

I ran another test in a Windows Server Core container and DLL's can be loaded with both 0.1.11 and 0.1.12 using Node.js 6.12.0.

BTW: I first tried the smaller NanoServer container, but it seems the the nwsdk DLL and binaries (from NWRFC_38-20004568.SAR) don't work in NanoServer.

Will do a more deep test if I have a SAP system at hand to connect to.

[StefanScherer]

Same error appears with FROM node:8.9.1 on Linux with node-rfc 0.1.12:
Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.21' not found (required by ...

Windows with FROM stefanscherer/node-windows:8.9.1-windowsservercore is fine with both 0.1.12.

Both Linux and Windows fail of course when trying with 0.1.11.

@bsrdjan,. I am not sure this is place to ask but any help is much appreciated.
We are trying to use node-rfc package in AWS lambda but curious to know that it's supported, we are a bit skeptical about it because it has a dependency on SAP NW libraries. Any idea? We are not sure how we can set a dynamic link to SAP libraries.
