@DancyHuang Thanks for reporting this problem. Judging from the several screenshots posted in the DingTalk group, one possible reason is that gcc9 and python3.8 was installed manually instead of through the package manager, which caused a Link problem: Bad value when compiling the PageRank application.

Could you please provide us more details about the installation of gcc and python3, or you can use our development image(based centos:7) to run GraphScope.

$ docker run --rm -it registry.cn-hongkong.aliyuncs.com/graphscope/graphscope-dev:wheel-v0.22.0 /bin/bash
$ [inside the container] $ unset GRAPHSCOPE_HOME && pip3 install graphscope
# then enjoy your time

@lidongze0629 yes, as you said , When I was installing GCC, I configured the directory incorrectly which resulted in ld not being able to find it. After dealing with this issue，I tested the installation by compiling a simple C program, confirming that the problem had been resolved and GCC was functioning as expected.

The pageRank run ok now .

Thanks and Best wishes!
