sorry, error in documentation, need to update. The @next refers to old release. Could you please try with the standard |

@bsrdjan still the same error:

Does the build from source starts after npm install ? If not, could you try to build from source on Alpine container? I need to test. |
|
Yes, I believe it is building from source successfully. I had to Here is the output from the docker build (I truncated the beginning as I don't think its relevant). See Then run the container:
Error in startup: EDIT: Repasted latest log which eliminates @latest tag from the npm install of node-rfc. Problem still persists. |

I forked the node-red-docker project and commited the custom make file for noderfc. Hopefully it helps you if you want to test it https://github.com/PaulWieland/node-red-docker/tree/master/docker-custom |

Does it have to be Alpine Linux? SAP NWRFC SDK is not supported on Alpine, here the list of supported platforms: https://launchpad.support.sap.com/#/notes/2573790 Did it work on nodeRED before, was it another Linux? The SDK usually works on common desktop/server Linux distros, with node-rfc built from source. Alpine is maybe different and SDK need to be compiled on that platform. That could be the feature request for SAP, because the SDK is closed source. |
|
Hi @bsrdjan, yes it worked on NodeRED before. The issue is that they changed their docker base image to use alpine in order to make it small and efficient. alpine is quite popular, it is the default base image for nodeJS docker containers (which is why NodeRED uses it), so a lot of nodeJS projects will be built on top of alpine. It would be really good to figure out how to get node-rfc and the NWRFC SDK working with it. |
|
Small update - I think this problem is related to alpine's use of Here's the truncated output of Notice that it's using |

Could you please send me the Dockerfile that I can build and logon to shell, to check? The build with Dockerfile above ends with error: $ docker build -t rfcami .

@bsrdjan agree the best case would be for SAP to support musl, I just don't know what the likely hood is of that ever happening (or where to even submit the request).

After the glibc added to node-rfc build script, the build fails with: Linking CXX shared library ../lib/binding/sapnwrfc.node

cannot find /usr/glibc-compat/lib/libc_nonshared.aNo idea why but here the setup which can used for further testing. Dockerfile.custom I added sudo, use the latest NWRFC SDK PL6 and mapped the local node-rfc repository clone to docker volume, to test build options. # setup:

Closing. I don't think this is possible or practical without a native MUSL version of nwrfc from SAP. |
@PaulWieland I found the place where to submit the request: https://launchpad.support.sap.com/#/notes/11 I personally consider the requirement relevant and it would be great if you could describe in more detail and submit the request. No guarantee it will be adopted but it helps when others can find and support the request. |

So i'm logged into the customer influence website. It seems that in order to submit an improvement request, I first have to pick a platform that I want improved - however I don't find anything seemingly relevant to the NWRFC software. Searching for Any ideas? |

To make the node-rfc available on Alpine Linux, SAP NWRFC SDK shall be supported on that platform. You can create or vote for SAP NWRFC SDK feature request, please see my comment above: #148 (comment) |

I'm trying to deploy noderfc under Alpine Linux (specifically node-red docker), but it seems like I might be having issues with ldconfig.
My dockerfile builds, but when my program runs I get the following error:
Error: Error relocating /usr/local/sap/nwrfcsdk/lib/libsapnwrfc.so: __strdup: symbol not foundThis is a really similar error as this one, so I am assuming this is an ldconfig problem. However I'm learning that under alpine
ldconfigis somehow different from other mainstream linux distros.I read that under alpine linux
LD_LIBRARY_PATH=/usr/local/sap/nwrfcsdk/libshould accomplish the same as loading the/etc/ld.so.conf.d/nwrfcsdk.confwithldconfigas you would do in other distros, but clearly something isn't working.Any ideas?
Here is my dockerfile (scroll to #### SAP RFC Stuff, the rest is standard node-red dockerfile).
P.S. There is a curl command to pull the nwrfcsdk.zip file from a local server since I do not think SAP hosts this file for public download - if I'm wrong about that please let me know so I can make a dockerfile that will work for everyone.
