Build on Mac

[liang7878]

cmake failed on macOS 11 when it tried to check gcc configuration. I have installed gcc-10 and cmake with homebrew. But it seems that it cannot work well when it tried to read the variable CMAKE_COMPILER_IS_GNUCC, could you please share some ideas about this error? Thanks.

We have never build tendis in macOS before.
We would check it later.

Thanks for issue.

This problem could be resolved by brew installed gcc, take a look at Build and run.

Hi @mingjliu9 , many thanks for your quick response. Here is my environment. As you can see below, I cannot see any evidence that it doesn't meet the requirements you mentioned in the document. Thanks.

You should link c++ to the path installed of g++, you can execute ln -s Path/To/g++ /Library/Developer/CommandLineTools/usr/bin/c++. We recommend that you use GCC 5.5 or GCC 7.3 version, because we tests tendis can be successfully compiled.
You can refer to @mingjliu9 's suggestions, take a look at our compilation document.

Thanks for issue.

我这边也遇到这个克服,mac 编译Tendis 现在能克服这个问题吗

[truongakevin]

I have this error also I think it can be ignored though. I tested this on a computer I know has a proper function c and c++ compiler it still said those tasks were skipped.
