@Shylock-Hg could you please take a look at it?

Mar 27 '23 01:03 wey-gu

Please show the compile options of nebual_graph_client library.

Mar 27 '23 01:03 Shylock-Hg

the nebual_graph_client was downloaded from nebula-cpp ,how can i get the compile options?

Mar 27 '23 02:03 chenlinzhong

Which do you download?

Mar 27 '23 02:03 Shylock-Hg

https://github.com/vesoft-inc/nebula-cpp/releases/download/v3.4.0/nebula-graph-client-3.4.0.el7.x86_64.rpm

Mar 27 '23 02:03 chenlinzhong

What's your version of OS?

Mar 27 '23 02:03 Shylock-Hg

Linux 4.14.0_1-0-0-42 #1 SMP Tue Jul 20 16:37:22 CST 2021 x86_64 x86_64 x86_64 GNU/Linux

Mar 27 '23 02:03 chenlinzhong

ok, you could try https://github.com/vesoft-inc/nebula-cpp/releases/download/v3.4.0/nebula-graph-client-3.4.0.el8.x86_64.rpm

Seems should build nebula-cpp in your environment, try cmake -DCMAKE_BUILD_TYPE=Release

Mar 27 '23 03:03 Shylock-Hg

do you have docker images that include dependencys so that i can build nebula-cpp from source code directly

Mar 27 '23 03:03 chenlinzhong

i do this ,but not success, build nebula-third-party occur many errors

Mar 27 '23 03:03 chenlinzhong

Try with this image https://github.com/vesoft-inc/nebula-dev-docker

export TAG=centos8
docker run -ti \
  -v "$PWD":/home/nebula \
  -w /home/nebula \
  --name nebula_dev \
  vesoft/nebula-dev:$TAG \
  bash

all third-party things are ready there.

@chenlinzhong I encountered this today on a CentOS 7 env that the rpm binary will suffer from issue of yours, too.

I then make instal it from the source to resolve it then.

We should fix the binary install issue @Shylock-Hg .
