Cygwin Make replacing /bin with /win64 in target - makefile

I have an odd problem running Make in Cygwin.
The makefile target is a call to an external tool that is installed on my Linux server at for example /apps/install_dir/tool_dir/bin/command.
The /apps nfs share is mapped to I drive in Windows.
But when I run make in Cygwin, it replaces the bin with win64 like this: /cygdrive/I/install_dir/tool_dir/win64/command
and therefore the command is not found.
Why does this occur and how can I fix it?

Installing Make in Cygwin

I am trying to build a Linux project in windows 7 environment usign cygwin. However I am continuously getting below error while configuring make for cygwin installation.
-bash: make: command not found
After searching on inernet the only solution is re running of setup and installed make package. I have installed automake1.15 but it is in noarch folder and there is no binary make.exe in bin folder.
run command setup-x86_64.exe -q --packages=make(because make is not installed) in command prompt where the setup-x86_64.exe file is available
There's a big difference between the 2:
[GNU]: Automake - Generates Makefile templates
[GNU]: GNU Make - Builds software from sources (via Makefiles)
So you need to select Make from Cygwin setup.
Notes:
Automake (or any package, as a matter of fact) is downloaded in the noarch dir, when it's compatible with any OS (Cygwin, in this case) architecture (32 bit and 64 bit (currently)), meaning that it doesn't contain binaries (.exes, .dlls (.sos)), only script-like files
Make on the other hand, does contain binaries (/usr/bin/make itself it is a binary) and will be downloaded in the appropriate dir (x86_64 or x86)
The download dir is not the same thing as the installation dir (there may be more than one, and it's under Cygwin installation dir)
For more (generic) details, check [Cygwin]: Installing and Updating Cygwin Packages.
[Cygwin]: Cygwin FAQ - Does the Cygwin Setup program accept command-line arguments? might also be a good starting point for command line options (check [SO]: Installing Make in Cygwin (#PJain's answer)).
Final note: Cygwin is kind of obsolete. Switch to WSL(2), which runs a real Ubuntu (no wrappers / adapters) as a VM (in Hyper-V - which runs at a totally different level).

Makefile.inc does not exist plexe-veins

I am new to command line and have followed all the threads related to make including downloading mingw and adding to both my system and user paths. I still get this error when I run mingw32-make.exe:
$ mingw32-make.exe
mingw32-make[1]: Entering directory 'E:/src/plexe-veins/src'
makefile:147: *** Config file '/e/src/omnetpp-5.3/Makefile.inc' does not exist -- add the OMNeT++ bin directory to the path so that opp_configf ilepath can be found, or set the OMNETPP_CONFIGFILE variable to point to Makefile.inc. Stop.
mingw32-make[1]: Leaving directory 'E:/src/plexe-veins/src'
makefile:12: recipe for target 'all' failed
mingw32-make: *** [all] Error 2
I have double checked if omnetpp-5.3 bin is in my path and yet I get the same error. Could anyone be so kind to point me in the right direction?
There are 3 things involved: mingw, msys and git for windows.
MSYS is a minimal unix-like environment featuring a shell and some tools. It uses an abstraction layer to make unix tools work under windows
MinGW is a GCC distribution to produce native windows binaries
Git for windows itself bundles msys to use for as terminal environment
The "git bash" from the context menu opens a terminal which itself runs a a stripped down msys (enough to interact with git). If you have mingw in your path it might autodetect it and includes it.
Now to your problem: The mingw32-make is meant to be used under native win32 - not the msys (git) prompt (it can be used, but might have shortcomings). You will need the msys make for that. The mingw installer offers the option for a msys base system - get that, it should include make. When installed open the msys prompt (not the git bash) and navigate to your folder, run configure again and try make.
Also make sure you are using the installed mingw gcc - try which gcc and see if the path you get matches the installed path.

How do I run a program linked against a DLL in MSYS?

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

How to compile a yacc (.y) file using Bison in Windows environment?

I've read http://dinosaur.compilertools.net/bison/bison_5.html#SEC25. But following those instruction i can not compile my yacc file using bison
How do i compile my file in windows 7 ... ?
Please help me to do this.
There is a common reason why bison will not operate properly on Windows and is mentioned in the install instructions but often overlooked. It is important that the name of the location of the directory that bison (and flex) is installed in (the path) does not contain a space. in particular this means that it cannot be placed under C:\Program Files\. The problem is that this directory might be suggest as the default install location. It is sometimes necessary to manually change the default to somethings else (like C:\GnuWin\ or similar). It is also usually necessary to manually add the appropriate directory to the PATH environment variable. Once this has been done there should be no problems in running bison and flex from the command prompt. It would normally be used in the following way:
flex lang.l
bison lang.y
gcc -o lang.exe lang.tab.c -lfl
It is not necessary to install MinGW, Cygwin or use Powershell or a VM or use linux as indicated by #DavidHefferman
If you still can't get it right, I even have an instructional video!
Using those Unix commands in Windows PowerShell might work, but I'm not sure and I'm currently not on Windows, so I can't check it.
If that fails you could try installing Cygwin (a basic Linux environment in Windows). You'd have to select the bison package during installation. It comes with its own shell that you can use.
Actually my personal favorite when programming under Windows is setting up a virtual machine with VirtualBox. That way you could use a real Linux environment without actually leaving Windows.
Good luck!

How to run a makefile in Windows?

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
