MinGW(GCC)

Closed this issue 4 months ago · 30 comments

I am using clion with MinGW compiler.Conan is detecting that i am using Visual Studio compiler

Auto detecting your dev setup to initialize the default profile (C:\Users\Name\.conan\profiles\default)

Found Visual Studio 14`

Default settings
        os=Windows
        os_build=Windows
        arch=x86_64
        arch_build=x86_64
        compiler=Visual Studio
        compiler.version=14
        build_type=Release

Indeed now cmake detects a wrong compiler.

CMake Error at .conan/conanbuildinfo.cmake:448 (message):
 Incorrect 'Visual Studio'.  Toolset specifies compiler as 'MSVC' but CMake   detected 'GNU'

How can i fix the compiler issue ?

Answer 1 · 2018-04-15T11:06:12.000Z

Create a profile for your MinGW toolchain here ~/.conan/profiles/mingw64, enter your settings eg.

[build_requires]
[settings]
    os=Windows
    os_build=Windows
    arch=x86_64
    arch_build=x86_64
    compiler=gcc
    compiler.version=7.2
    compiler.libcxx=libstdc++11
    build_type=Debug
[options]
[env]

Then use that profile when installing:

conan install .. --build=missing --profile=mingw64

Answer 2 · 2018-04-15T11:21:32.000Z

Thanks you i was missing the compiler.libcxx=libstdc++11

However i get another error even with the correct profile

Clion works with cmake just fine though

Answer 3 · 2018-04-15T14:56:51.000Z

The problem is

'cmake' is not recognized as an internal or external command

MinGW gives you a minimal PATH which does not inherit the regular Windows PATH. You need to add CMake to the MingGW PATH. One way to do it is to add CMake to the PATH in ~/.bashrc in MinGW. For example, assuming CMake is installed in C:\Program Files\CMake:

export PATH=/c/Program\ Files/CMake/bin:$PATH

This way you can also run CMake from the MinGW command line.

Alternatively you can add CMake to the PATH in your profile.

Answer 4 · 2018-04-15T15:15:38.000Z

What do you mean by adding CMake to MingGW PATH.I would like to use the cmake Bundled in MinGW itself.

If i add Cmake to PATH in my profile i get the following

CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMake was unable to find a build program corresponding to "MinGW Makefiles". CMAKE_MAKE_PROGRAM is not set. You probably need to select a different build tool. CMake Error: CMAKE_C_COMPILER not set, after EnableLanguage CMake Error: CMAKE_CXX_COMPILER not set, after EnableLanguage

Thanks a lot for the help

Answer 5 · 2018-04-15T15:25:46.000Z

Which shell are you running? And what is your full PATH? For example:

echo $PATH

You want to have the directory that contains mingw32-make.exe in your PATH.

For example, if you are using msys2 installed in C:\msys2 then you'll want to add /c/msys2/mingw64/bin to your PATH in ~/.bashrc. But it should already be there if you are running the MinGW64 shell.

Alternatively you can add this to your profile:

[env]
CMAKE_MAKE_PROGRAM=C:\msys2\mingw64\bin\mingw32-make.exe

Answer 6 · 2018-04-15T15:49:33.000Z

Actually if you have CMake installed in mingw64, then just having /c/msys2/mingw64/bin in your PATH will work. You won't need /c/Program\ Files/CMake/bin too (that would be CMake installed for Windows).

You can tell by starting up a Mingw64 shell and running which cmake.

i am on windows 7

Answer 8 · 2018-04-15T16:03:01.000Z

Ok - so it looks like you are not running a Mingw or Msys2 shell. You are running a regular Windows command prompt, is that correct?

What files are in C:\Program Files\mingw-w64\x86_64-7.2.0-posix-seh-rt_v5-rev1\mingw64\bin?

Answer 9 · 2018-04-15T16:05:15.000Z

Yes i am running a regular windows command prompt.I have many exe there like gcc.exe but cmake.exe isn't there.How is Clion detecting Cmake as Bundled then.

Answer 10 · 2018-04-15T16:08:34.000Z

Is mingw32-make.exe in C:\Program Files\mingw-w64\x86_64-7.2.0-posix-seh-rt_v5-rev1\mingw64\bin?

CLion has its own CMake that is bundled in the CLion installation.

Answer 11 · 2018-04-15T16:14:15.000Z

I'm curious how you installed Mingw. I would like to try to install it the same way to try out.

Answer 12 · 2018-04-15T16:29:43.000Z

As far as i can remember i install mingw64 and then that's it.

https://sourceforge.net/projects/mingw-w64/

Later i installed Cmake Gui as well for some other purpose
https://cmake.org/download/

In fact i just took cmake.exe from that cmake directory and pasted it in mingw64\bin

That seems to fix that specific error but it leads to another one

There seems to be some kind of issue with the path again

'C:\Program' is not recognized as an internal or external command,

Answer 13 · 2018-04-15T17:57:28.000Z

I would not recommend copying stuff into mingw64\bin. If CMake is in your Windows PATH then that's all that should be necessary.

Some of the advice that I was giving you earlier was assuming that you were using msys2 as a command line shell. That's why I was talking about ~/.bashrc. You can ignore that stuff, also when I said "MinGW gives you a minimal PATH", that is msys2-related too.

To debug the error that you are seeing you should look in the CMakeFiles directory for CMakeError.log to see exactly what the cause is.

On the other hand, rather than trying to get Conan working with your installation of MinGW an alternative is to use the mingw_installer in your profile. This will download a copy of MinGW into your Conan local cache and will automatically set up all of the environment variables correctly. For example, add this to your profile:

[build_requires]
mingw_installer/1.0@conan/stable

Then you can remove this from your profile:

[env]
CMAKE_MAKE_PROGRAM=C:\msys2\mingw64\bin\mingw32-make.exe

Also this way it won't be tied to your particular installation of MinGW.

Answer 14 · 2018-04-15T18:09:00.000Z

ERROR: mingw_installer/1.0@conan/stable: 'settings.compiler.exception' value not defined

Answer 15 · 2018-04-15T18:54:26.000Z

I was able to replicate the problem that you had

'C:\Program' is not recognized as an internal or external command`

Unfortunately I wasn't able to figure out (yet) how to fix it without using mingw_installer/1.0@conan/stable. I'll try to figure that out at a later time.

This error:

ERROR: mingw_installer/1.0@conan/stable: 'settings.compiler.exception' value not defined

Is due to a missing profile setting. I was able to install zlib from source using this profile:

[build_requires]
mingw_installer/1.0@conan/stable

[settings]
os_build=Windows
os=Windows
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=7
compiler.exception=seh
compiler.libcxx=libstdc++11
compiler.threads=posix
build_type=Debug

Note the compiler.exception=seh

Answer 16 · 2018-04-15T19:04:40.000Z

I believe you should install Mingw to a path without spaces to fix 'C:\Program' is not recognized as an internal or external command. For instance in C:\some_folder\.

Answer 17 · 2018-04-15T19:21:50.000Z

Yep - you're right. After I moved C:\Program Files\mingw-w64 to C:\mingw-w64 and used the profile:

[settings]
os_build=Windows
os=Windows
arch=x86_64
arch_build=x86_64
compiler=gcc
compiler.version=7
compiler.exception=seh
compiler.libcxx=libstdc++11
compiler.threads=posix
build_type=Debug

[env]
CONAN_CMAKE_GENERATOR=MinGW Makefiles

Then I was able to

conan install zlib/1.2.11@conan/stable --build zlib -pr mingw64

Also, that's why

[build_requires]
mingw_installer/1.0@conan/stable

worked, is because the Mingw directory in the Conan cache didn't have a space in it.

Answer 18 · 2018-04-16T07:36:11.000Z

It is very typical indeed that build scripts of libraries or some recipes won't work well with path with spaces. Not only for conan, but many other tools. I always make sure to install things when possible in paths without spaces and without any special (other than ascii) characters, it saves a lot of pain later.

Answer 19 · 2018-04-16T14:49:50.000Z

I'm surprised that the Mingw installer installs to C:\Program Files by default. That's crazy! I didn't notice it the first time that I went through the wizard.

Answer 20 · 2018-04-16T17:10:12.000Z

It seems like some ddl was not found

What is ddl? Did you mean dll?
How did you arrive at this conclusion?

If I were you, I would run it in a debugger to see where it is crashing.
Or you could use some dependency analyzer tool to check what libraries the binary requires.

BTW it would be easier for people to help you if you provided: detailed steps to reproduce your problem, expected result, actual result and environment information.

Answer 28 · 2018-04-25T22:14:25.000Z

The bug is in your program, you have an uninitialized z_stream zs; in function CompressStringGzip. Initializing it with z_stream zs{}; fixes the problem.

Anyway, I don't have CLion, only Qt Creator and I tested it on Msys2 with these modifications to your files to make life easier:

CMakeLists.txt

cmake_minimum_required(VERSION 3.10)

Answer 30 · 2024-05-08T18:49:07.000Z

This issue was quite outdated from 2018, until recent @Baneeishaque comment.

I have just tried exactly that, having a tool-requires to mingw-builds/12.2.0 and it works pretty well, I am closing this ticket as outdated/solved, and I will probably open a PR to the docs with an example.

If there is any further issue or question, please create a new ticket. Many thanks!
