Can not run clickhouse on another Centos6

[James Wang]

Hi All,

This time the error is when I tried to run clickhouse:

kernel: clickhouse[3395] trap invalid opcode ip:2c5c76d sp:7fff848a8860 error:0 in clickhouse

It is Centos 6.

Please advise why this error .

Thanks a lot

Hi James!

Most probably it means that your CPU does not support SSE 4.2 instruction set. You can check this by running the following command:

grep -q sse4_2 /proc/cpuinfo && echo "SSE 4.2 supported" || echo "SSE 4.2 not supported"

You can recompile ClickHouse so that it doesn't require SSE 4.2, but results are better if the support is present.

How to please?

Thanks a lot indeed

To compile without sse4 you need to either compile on your target architecture (cmake then automatically detect which processor features are supported) or manually turn off support by running cmake with the following flags:

cmake -DHAVE_POPCNT=0 -DHAVE_SSE41=0 -DHAVE_SSE42=0 ..

Note that build without sse4.2 was broken without this patch: https://github.com/yandex/ClickHouse/commit/8763567e9a6fc47614ff8dec40d984562d887aec

You can apply it yourself (compiling directly from master is not recommended, only from one of the stable tags).

May I ask what is the system you intend to run ClickHouse on? All modern x86_64 processors support sse4, so it should not be a problem.

Thanks a lot indeed.

I need to upgrade my Centos.

With best regards
