I'm switching from VS to CLion and they said I needed to install Cygwin and CMake. I then installed both of them. I tried use bundled, but CLion still gives me these errors make: not found C Compiler: not found C++ Compiler: not found GDB: not found.
I have installed CMake under the path C:\Users\Gaga\Downloads\cmake-3.4.1 but I don't see a cmake.exe, the closest thing is cmake.cxx.
Without these I'm not able to compile anything, please help
In the "Use specified" field I put C:\cygwin64\bin\cmake.exe your path may be different. Just ensure you have CMake, Make, gdb and gcc installed already in Cygwin (using the Cygwin setup.exe not via the CMake website) but I believe Clion checks if you have them installed after inputting the path.
The workaround would be to use MinGW. If you download it from the website it should come with cmake, and take care of the errors.
http://mingw.org/
When extract it and go to the installer you should check something like gcc and then from the top left corner something like 'install packages'
Be sure not to accidentally download the source, which I did, which would lead you toward this error: CLion: CMake Errors Source directory does not exist
Edit: So over a year later, I've learned a little more about Cygwin and mingw beyond what the internet says. CLion needs a "Unix-like" environment. If you use CLion on MacOS or a Linux it's already Unix based. Anything that is "POSIX" compliant will work. CygWin is a terminal emulator for windows where Unix commands like mkdir work. MinGW is something similar but not posix. Comes with GCC tho. I'm still a noob.
I had the same problem.
While installing cygwin, need to select the packages of cmake, gcc, gdb
Got the answer from the below link.
Select Packages while installing cygwin
After the installation go to the configuration page and select the cygwin directory. CLion will identify the configuration and you are done...
I've successfully built a demo app using opencv on windows with the MSYS shell environment.
I did NOT use the prebuilt opencv installer, I downloaded and compiled the source locally (this is the recommended method).
After building opencv and running make install, all the files are happily in:
/e/deps/libopencv/build/install/
I can successfully build a sample application against this using cmake directives along the lines of:
find_package(OPENCV REQUIRED)
link_directory(${OpenCV_LIB_DIR})
include_directories(${OpenCV_INCLUDE_DIRS})
target_link_libraries(target ${OpenCV_LIBS})
To be completely clear here: building the binary is successful.
Now, when I run it from the shell I get the message:
The program can't start because libopencv_core231.dll is missing from your computer.
Try reinstalling the program to fix this problem.
So... I know where the libraries are:
$ ls /e/deps/libopencv/build/install/lib/
libopencv_calib3d231.dll.a libopencv_features2d231.dll.a libopencv_highgui231.dll.a libopencv_ml231.dll.a libopencv_video231.dll.a
libopencv_contrib231.dll.a libopencv_flann231.dll.a libopencv_imgproc231.dll.a libopencv_objdetect231.dll.a
libopencv_core231.dll.a libopencv_gpu231.dll.a libopencv_legacy231.dll.a libopencv_ts231.a
What now?
I guess I could try to make cmake build a static binary, but that seems pretty extreme.
How can I somehow make either 1) windows, or 2) the MSYS environment happy. Something like LD_LIBRARY_PATH on windows?
Or is this not the problem, and I've actually (despite appearances) somehow messed up the way the binary was compiled?
Edit:
NB. For whatever reason it seems that my libraries are .dll.a files, not .dlls (see the ls result) if that's remotely relevant.
windows searches the same directory as the exe, any directory in the %PATH% (Windows) or $PATH (msys) directories, as well as a few special ones in the windows folder
You could add /e/deps/libopencv/build/install/lib to your $PATH. I am not sure if this will work for msys, you may need to add E:\deps\libopencv\build\install\lib to %PATH% in windows instead.
The typical solution for this if you are giving the program to others is to include a copy of the DLL in the same directory as the EXE. you can get this same effect by making a symbolic link to it with the command
ln -s /e/deps/libopencv/build/install/lib/libopencv_core231.dll libopencv_core231.dll
while in the /e/deps/libopencv/build/install/ directory
I have installed Cygwin on my system. But when I try to use the gcc command it says:
bash: gcc: command not found
Can anyone provide me the solution, please?
In my installation there was no generic gcc command either, so I made a symlink for it:
cd /usr/bin
ln -s i686-pc-cygwin-gcc-3.4.4.exe gcc
Now check if it worked by doing which gcc which should give you /usr/bin/gcc and then gcc should give you gcc: no input files. Note that your version of i686-pc-cygwin-gcc-3.4.4.exe may be different. Check in /usr/bin for it.
Maybe during installation of Cygwin you have not selected gcc, gdb and make packages.
I had the same problem and it was resolved after I selected above-mentioned packages.
A couple of things:
I always install the whole Cygwin package. Earlier versions had troubles with dependencies that are fixed now, I believe, but it's still a good habit. You never know when you may need the most esoteric bit of Cygwin.
You may have to change your path. All the tools can generally be found okay if you're running inside the Cygwin bash shell but that's not necessarily the case from cmd.exe.
It's unlikely to be that last one since your error message is coming from bash itself, so I'm pretty certain that's how you're running it.
Have a look to make sure you have /usr/bin/gcc from within bash and that your path includes /usr/bin somewhere:
pax> echo $PATH
/usr/local/bin:/usr/bin:/bin:/cygdrive/c/WINDOWS/system32:/cygdrive/c/WINDOWS
pax> which gcc
/usr/bin/gcc
If it's not there, go back and re-install everything (or the relevant development package if you don't want everything). If it is there and your path doesn't have its location, change your path, in either /etc/profile or the equivalent in your home directory.
Another related issue that wasn't mentioned here, is from the command line the compiler needs the environment path variable updated to find the location of the c++ header files. In windows you can just update the path environment using the 'advanced system properties' GUI and add the location of the c++ include files. This will update the PATH environment variable in Windows cmd & Cygwin automatically upon restarting the shell.
To update your PATH from Linux or the Cygwin shell type... PATH=$PATH:/your_path_here Example:PATH=$PATH:/cygdrive/c/cygwin/lib/gcc/i686-pc-mingw32/4.7.3/include/c++ Also a good idea to add just the include directory as well: PATH=$PATH:/cygdrive/c/cygwin/lib/gcc/i686-pc-mingw32/4.7.3/include/ ...or check the proper directories for the location of your installation's include files, I recommend installing mingw for use with Cygwin, which is envoked with g++.
To install additional needed packages in Cygwin re-run the Cygwin install utility & check install from Internet to add packages from web repositories and add mingw-gcc-g++ & mingw-binutils. To compile your code: g++ hello.cpp -o hello
If using the gcc utility instead compile with the command: gcc hello.cpp -o hello -lstdc++ ... to get your executable.
As long as you have either gcc or mingw installed and the path to the c++ include files is in your path environment, the commands will work.
There is another hard to spot mistake could also cause this error,
If your Makefile uses PATH as variable, the gcc not found error could happen.
This is because it changes the system path temporarily.
I took a lot of time checking the cygwin environment setting to discover this, so I'll leave it here in case this helps anyone finding their way here.
I have some demos that I downloaded and they come with a Makefile.win and a Makefile.sgi. How can I run these in Windows to compile the demos?
You can install GNU make with chocolatey, a well-maintained package manager, which will add make to the global path and runs on all CLIs (powershell, git bash, cmd, etc…) saving you a ton of time in both maintenance and initial setup to get make running.
Install the chocolatey package manager for Windows
compatible to Windows 7+ / Windows Server 2003+
Run choco install make
I am not affiliated with choco, but I highly recommend it, so far it has never let me down and I do have a talent for breaking software unintentionally.
If you have Visual Studio, run the Visual Studio Command prompt from the Start menu, change to the directory containing Makefile.win and type this:
nmake -f Makefile.win
You can also use the normal command prompt and run vsvars32.bat (c:\Program Files (x86)\Microsoft Visual Studio 9.0\Common7\Tools for VS2008). This will set up the environment to run nmake and find the compiler tools.
Check out GnuWin's make (for windows), which provides a native port for Windows (without requiring a full runtime environment like Cygwin)
If you have winget, you can install via the CLI like this:
winget install GnuWin32.Make
Also, be sure to add the install path to your system PATH:
C:\Program Files (x86)\GnuWin32\bin
Check out cygwin, a Unix alike environment for Windows
Here is my quick and temporary way to run a Makefile
download make from SourceForge: gnuwin32
install it
go to the install folder
C:\Program Files (x86)\GnuWin32\bin
copy the all files in the bin to the folder that contains Makefile
libiconv2.dll libintl3.dll make.exe
open the cmd (you can do it with right click with shift) in the folder that contains Makefile and run
make.exe
done.
Plus, you can add arguments after the command, such as
make.exe skel
If you install Cygwin. Make sure to select make in the installer. You can then run the following command provided you have a Makefile.
make -f Makefile
https://cygwin.com/install.html
I use MinGW tool set which provides mingw32-make build tool, if you have it in your PATH system variables, in Windows Command Prompt just go into the directory containing the files and type this command:
mingw32-make -f Makefile.win
and it's done.
I tried all of the above. What helps me:
Download the mingw-get.
Setup it.
Add something like this C:\MinGW\bin to environment variables.
Launch (!important) git bash. Power shell, developer vs cmd, system cmd etc didn't help.
Type mingw-get into the command line.
After type mingw-get install mingw32-make.
Done! Now You might be able to use make-commands from any folder that contains Makefile.
With Visual Studio 2017 I had to add this folder to my Windows 10 path env variable:
C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\VC\Tools\MSVC\14.10.25017\bin\HostX64\x64
There's also HostX86
If it is a "NMake Makefile", that is to say the syntax and command is compatible with NMake, it will work natively on Windows. Usually Makefile.win (the .win suffix) indicates it's a makefile compatible with Windows NMake. So you could try nmake -f Makefile.win.
Often standard Linux Makefiles are provided and NMake looks promising. However, the following link takes a simple Linux Makefile and explains some fundamental issues that one may encounter. It also suggests a few alternatives to handling Linux Makefiles on Windows.
Makefiles in Windows
Firstly, add path of visual studio common tools (c:\Program Files (x86)\Microsoft Visual Studio 14.0\Common7\Tools) into the system path. To learn how to add a path into system path, please check this website:
http://www.computerhope.com/issues/ch000549.htm. You just need to this once.
After that, whenever you need, open a command line and execute vsvars32.bat to add all required visual studio tools' paths into the system path.
Then, you can call nmake -f makefile.mak
PS: Path of visual studio common tools might be different in your system. Please change it accordingly.
I tried with cygwin & gnuwin, and didn't worked for me, I guess because the makefile used mainly specific linux code.
What it worked was use Ubuntu Bash for Windows 10. This is a Marvel if you come from MAC as it is my case:
To install the Ubuntu Bash: https://itsfoss.com/install-bash-on-windows/
Once in the console, to install make simply type "make" and it gives the instructions to download it.
Extras:
Useful enable copy / paste on bash: Copy Paste in Bash on Ubuntu on Windows
In my case the make called Maven, so I have to install it as well: https://askubuntu.com/questions/722993/unable-to-locate-package-maven
To access windows filesystem C: drive, for example: "cd /mnt/c/"
Hope it helps
Install msys2 with make dependency add both to PATH variable.
(The second option is GNU ToolChain for Windows. MinGW version has already mingw32-make included.)
Install Git Bash. Run mingw32-make from Git Bash.
If you have already installed the Windows GNU compiler (MinGW) from MSYS2 then make command comes pre-installed as wingw32-make. Always match cmake makefile generation with the correct make command. Mixing these generate problems.
MinGW makefile generation with MinGW make command
Visual Studio makefile generation with VS equivalent make command
And this is always possible as long as you have the source code. Just delete old build directory and start over by specifying this time the right parameter in cmake ,e.g.
mkdir build
cd build
cmake -G "MinGW MakeFiles" path/to/src/whereCMakeLists.txtInstructionsAre
mingw32-make
myProject.exe # RUN
I have encountered issues during compilation where multiple make commands interact. To prevent this just edit/remove the environmental variables that lead to different make commands. For example to prevent conflicts with mingw, keep only C:\msys64\mingw64\bin but remove C:\msys64\usr\bin. That other path contains the msys make and as I said you do not want to combine make commands during compilation.
Download from https://sourceforge.net/projects/gnuwin32/
Set the variable path in advance setting for recognize in command prompt (C:\Program Files (x86)\GnuWin32\bin)
So if you're using Vscode and Mingw then you should first make sure that the bin folder of the mingw is included in the environment path and it is preferred to change the mingw32-make.exe to make to ease the task and then create a makefile
and include this code in it .
all:
gcc -o filename filename.c
./filename
Then save the makefile and open Vscode Code terminal and write make. Then makefile will get executed.
I am assuming you added mingw32/bin is added to environment variables else please add it and I am assuming it as gcc compiler and you have mingw installer.
First step: download mingw32-make.exe from mingw installer, or please check mingw/bin folder first whether mingw32-make.exe exists or not, else than install it, rename it to make.exe.
After renaming it to make.exe, just go and run this command in the directory where makefile is located. Instead of renaming it you can directly run it as mingw32-make.
After all, a command is just exe file or a software, we use its name to execute the software, we call it as command.
For me installing ubuntu WSL on windows was the best option, that is the best tool for compiling makefile on windows. One thousand is better than Cygwin64, because to compile a makefile you will need another package and compile software like maybe gfortran, netcdf, etc, ect, in ubuntu WSL you can install all of these packages very easily and quickly ;)
The procedure I followed is;
I installed Gnuwin32's make using the installable.
Added the "make" path to the environmental variable PATH.
Verified the installation using "make --version"
Go to http://gnuwin32.sourceforge.net/packages/make.htm and download make-3.81.exe, install and add to Windows path.
May be it can work.
pip install Makefile
From llvm.org I've downloaded llvm-2.6-x86-mingw32.tar.bz2 into c:\llvm and llvm-gcc-4.2-2.6-x86-mingw32-tar.bz2 into c:\llvm-gcc as well as setup a desktop shortcut the following batch file in c:\llvm-gcc which attempts to setup an environment for compiling via the llvm-gcc command line too:
#echo off
color 0E
echo Configuring LLVM environment...
set LLVM_LIB_SEARCH_PATH=%~dp0lib
set PATH=c:\llvm;%~dp0bin;%PATH%
Unfortunately, this setup gives the following error when trying to compile a simple hello world program:
C:\CDev\sandbox>llvm-gcc -o hello.exe hello.c
llvm-gcc: CreateProcess: No such file or directory
I've briefly looked through the LLVM binaries and it appears that the MinGW-based Win32 API and runtime files are already included. I also tried adding the MinGW DLL to c:\llvm-gcc\bin to no avail.
What have I missed in setting up the binary LLVM environment and GCC-based front end on Vista?
Thanks, Jon
Because the GNU/MinGW assembler 'as' was required by 'llvm-gcc' to generate the obj file. The problem can be solved by using:
Install GNU/MinGW binutils, extract the as.exe into c:\llvm-gcc\bin
Install a full MinGW package, add %MinGW%\bin your %PATH%
#rwallace is correct that one needs to also install MinGW's binutils along with the LLVM binary download. I've updated the LLVM documentation appropriately at
http://llvm.org/docs/GettingStarted.html#installcf
As far as I can tell, the answer is that the MinGW distribution supplied by LLVM is not complete, in particular, it doesn't come with the 'binutils' programs.
The recommended solution seems to be to download and install MinGW yourself. However, the MinGW download page seems to be saying this requires 10 different packages to be downloaded and installed separately.
The solution I tried today was to use the MinGW that comes with Qt, which does come in a single package; thus far, that appears to work.
It seems like it is looking for the base MinGW installation in C:\MinGW. I just had this error today using gcc.exe in msys. To solve it, I created a symbolic link from c:\msys to c:\MinGW and everything worked.
