My clion's cmake occurs error

Hello!

It's unclear what's going on. Have you tried reinstalling MinGW completely and setting it up as described here https://www.jetbrains.com/help/clion/quick-tutorial-on-configuring-clion-on-windows.html#MinGW?

Anna，I reload MinGW after Clion broken.I use cmd to review gcc's version，and show MinGW working well.Today,according to you advise and i follow quick Toutor configuring Clion mehton ,problem still exsises.By the way,i choose download Compression package from mingw-w64.org because my net online install mingw by mingw setup.exe always faild.

It looks like something is wrong with your MinGW distribution. I'd suggest to download MinGW-W64-install.exe and install MinGW-w64 using it.

Anna，i have install MinGW-W64,and set enviroment path.Mingw itself is not problem. But there is a new problem.

Anna,I'm really want to cry！！！I'm about to run！！！！

Hi,

Can you please try compiling any C++ file using MinGW gcc directly from command line?

For this you have to first add path to MinGW bin directory into PATH variable. E.g. using this command

`set PATH="D:\Program Files\mingw64\mingw64\bin";%PATH%`

Then run gcc using command `gcc main.cpp` where file `main.cpp` you can take from the newly created CLion project. This will allow us to better understand where's the poblem

Semyon Kolton,I can compiling C program from cmd by GCC command，and i have set MinGW bin into PATH variable already.It's seem everything done well.But Clion alway report Cmake error.I confused about everyting goes well before till i create C project 7-"P7".when i were codeing for P7,other files still could run,and i searched method from net a lot but could not  solved P7's problem.I attempted to unload and reload Clion and MinGW.

Does the issue happen only for your "P7" project now? Or for all projects?

Anna Falevskaya this issue had happend after i created P7 firstly.I attempted to run P6,and worked well,i am sure that problem was only happen for P7.After i reload Clion, problem is exsis in every project,including those the past is normal.

Anna Falevskaya ，Semyon Kolton. I trying to use DEV-c++'s bin directory.I find that camke do not report error.Clion can work and complier C programes .I am happy to slove this issue.But i have a question why i download MinGW from MinGW.org or intasll MinGW by intasll.exe application are useless for several times even thorogh cmd show gcc and g++ well.In the end ,thank for your efforts and help. 

I'm glad you solved the issue!

>But i have a question why i download MinGW from MinGW.org or intasll MinGW by intasll.exe application are useless for several times even thorogh cmd show gcc and g++ well.

I'm afraid we can't answer that. For example, on my side MinGW installed using MinGW-W64-install.exe works correctly. So it seems to be a specific issue with a particular installation and setup rather than a CLion related issue.
