Error: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.26' not found (required by /usr/src/app/node_modules/node-rfc/lib/binding/sapnwrfc.node)

I am using ubuntu 20.04 and the SDK is Linux on X86_64 64 bit. But I am getting the above error. I tried to solve this issue with the solution you provided in https://github.com/SAP/node-rfc/issues/165, but it doesn't seem to solve it. Please suggest if there is any other way to solve it.

can you share the node-rfc installation log and the output of strings /usr/lib/x86_64-linux-gnu/libstdc++.so.6 | grep GLIBC ?

Could it be more libstdc versions on your system and the older one takes the precedence: https://askubuntu.com/questions/1166292/version-glibcxx-3-4-26-not-found-even-though-libstdc-so-6-recent-enough

and the installation log?

[bsrdjan]

It looks like an older system, perhaps upgraded to Ubuntu 20 but not completely. You can try with new Ubuntu 20 installation, or update/upgrade the system, something like

sudo apt-get install libstdc++6
sudo apt-get update
sudo apt-get upgrade

In any case, the build from source installation is recommended on Linux platforms because node-rfc Linux binary does not fit for all Linux systems.

For build fron source you should first install CMake and run:

npm install --build-from-source node-rfc

More details here: https://cmake.org/install/ You can also refer to automated CMake installation in this docker container: https://github.com/SAP/fundamental-tools/blob/main/docker/common/nodejs.Dockerfile

Hi @bsrdjan , I managed to fix the issue thanks to your suggestion. But now on the server I am getting the following error: "message": { "name": "RfcLibError", "group": 4, "code": 1, "codeString": "RFC_COMMUNICATION_FAILURE", "key": "RFC_COMMUNICATION_FAILURE", "message": "\nLOCATION CPIC (TCP/IP) on local host with Unicode\nERROR hostname 'xxxxxx' unknown\nTIME Tue Jun 13 09:41:30 2023\nRELEASE 753\nCOMPONENT NI (network interface)\nVERSION 40\nRC -2\nMODULE /bas/753_REL/src/base/ni/nixxhl.cpp\nLINE 198\nDETAIL NiHLGetNodeAddr: hostname cached as unknown\nCOUNTER 3" }

It is either a network error or error in client connection parameters. Please re-open if not fixed in the meantime.
