Clojurians Log v2

@anmonteiro do you know anything about this error?

/codebuild/output/tmp/versions/node/v9.11.1/lib/node_modules/lumo-cljs/bin/lumo: /usr/lib/x86_64-linux-gnu/libstdc++.so.6: version `GLIBCXX_3.4.20' not found (required by /codebuild/output/tmp/versions/node/v9.11.1/lib/node_modules/lumo-cljs/bin/lumo)

is lumo missing a dependency? or do I need to install that version of GLIBC via some other means?

hrm

@johanatan which dist/ version of linux does that machine run

aws/codebuild/java:openjdk-9

i think Ubuntu 13

yeah… that sounds right

actually 14.04

https://github.com/anmonteiro/lumo/issues/137

Defined here: https://github.com/aws/aws-codebuild-docker-images/tree/master/ubuntu/java/openjdk-9

can you upgrade to a later version of ubuntu?

14.04 is pretty late yea?

or just install libstdc++6

well…

14.04 means April 2014

ooh, right

how to install libstdc++6 ? via apt-get?

I thought it wasn't possible to install linux in the first place without libstdc++.so.6

this looks like it: https://askubuntu.com/questions/726539/sudo-apt-get-install-libstdc?utm_medium=organic&utm_source=google_rich_qa&utm_campaign=google_rich_qa

@johanatan yes, apt-get install -y libstdc++6

what's your output johnatan when you do echo $LD_LIBRARY_PATH

@hlolli just a sec. not a live environment so i have to wait for runs to complete. trying that SO suggestion first

readelf -d lumo                           ~/.npm-global/lib/node_modules/lumo-cljs/bin

same elf signature in node for me, so I wonder if node runs for you.

yea, node runs fine

there's some difference there actually between node 9.8.0 and latest lumo on npm

readelf -sW lumo | grep GLIBCXX_3.4.20    ~/.npm-global/lib/node_modules/lumo-cljs/bin

$

could be that your libstc++ version is just old

GCC 4.9.0: GLIBCXX_3.4.20, CXXABI_1.3.8

maybe we can rethink about statically linking lumo. I wasn't able to load dynamically linked native node modules on runtime with statically linked lumo, it just crashed. Maybe since then it has been fixed, or we can find a workaround on that.

Any plans for packaging lumo-cljs for raspberry pi via npm in the future?
