Setting up SDL2 on Windows with VS Code and mingw - c++

I'm trying to setup SDL2 on windows with vs code and mingw. I have some example code and both the include and lib folders in a src folder in my project. I also have a MakeFile:
When I open a terminal and type "make" I get the following error.
g++ -Isrc/Include -Lsrc/lib -o main main.cpp -lmingw64 -lSDL2main -lSDL2
C:/msys64/mingw64/bin/../lib/gcc/x86_64-w64-mingw32/12.1.0/../../../../x86_64-w64-mingw32/bin/ld.exe: cannot find -lmingw64: No such file or directory
collect2.exe: error: ld returned 1 exit status
make: *** [Makefile:2: all] Error 1
My include path in the C/C++ Configurations Extension is "${workspaceFolder}/**".
I also looked in my mingw folder and found the g++.exe I think I need but am not sure why it's saying there is no such file or directory.

Build curl lib with Mingw compiler

I want to use the curl lib in my project (c++ QT creator on windows), I download the zip lib file from the website https://curl.se/download.html (Version 7.82.0)
and I wanted to build it using the Makefile with this commend
mingw32-make mingw32 as described in the documentation https://curl.se/docs/install.html
but unfortunately, I am getting an error
mingw32-make mingw32

I tried to run ranlib lib\libcurl.a but the issue is still there,
does anyone have an idea about it?
One more question: is it possible also to build it with mingw64?

OpenCV + Eclipse on Linux - Build issues

I downloaded opencv from here and extracted it to /home/XXXX/Documents/opencv-4.4.0.
I want to link it to Eclipse. So I did this -
In the project settings -> GCC C++ Compiler -> include path I gave /home/XXXX/Documents/opencv-4.4.0.
Then in the linker section I added the libraries and set the library search path to /home/XXXX/Documents/opencv-4.4.0 and even /home/XXXX/Documents/opencv-4.4.0/include.
When I build the project, I get this error -
18:50:10 **** Incremental Build of configuration Debug for project displayImage ****
make all
Building file: ../src/displayIMage.cpp

| ^~~~~~~~~~~~~~~~~~~~~~~~~~~~
compilation terminated.
make: *** [src/subdir.mk:20: src/displayIMage.o] Error 1
"make all" terminated with exit code 2. Build might be incomplete.
I followed everything according to this tutorial. I tried running pkg-config --cflags opencv to find the right paths but that gave me this error -
Package opencv was not found in the pkg-config search path.
Perhaps you should add the directory containing `opencv.pc'
to the PKG_CONFIG_PATH environment variable
No package 'opencv' found
What am I doing wrong?

Linking library with gcc - ld: cannot find -larpack

I am installing software on a server with no root privileges. I come across the following error during installation:
make[1]: *** [hgaprec] Error 1
make[1]: Leaving directory `/seq/.../SOFTWARE/hgaprec/src'
make: *** [all-recursive] Error 1
Making install in src
make[1]: Entering directory `/seq/.../SOFTWARE/hgaprec/src'

collect2: error: ld returned 1 exit status
make[1]: *** [hgaprec] Error 1
make[1]: Leaving directory `/seq/.../SOFTWARE/hgaprec/src'
make: *** [install-recursive] Error 1
Since library arpack could not be found, I then installed it here /seq/.../SOFTWARE/hgaprec/ARPACK and found that the process generated a static file libarpack_LINUX.a. To link this static library to gcc the following command was used:
gcc -larpack -L/seq/.../SOFTWARE/hgaprec/ARPACK/libarpack_LINUX.a
However, I keep getting the same error while installation of the software that larpack was not found. Am I using the linking command wrong?
You either want gcc main.c /seq/../SOFTWARE/hgaprec/ARPACK/libarpack_LINUX.a (you don't need -l and -L if you're specifying the full path to static library), or as #Julian_Cienfuegos suggested gcc main.c -L/seq/../SOFTWARE/hgaprec/ARPACK/ -larpack_LINUX. This assumes you're only compiling a single file called main.c which contains your main() function, and outputs the a.out binary.
EDIT: Added explanation of main.c.
My issue got solved after including the ARPACK library path as part of LD flag in configure like so:
./configure --prefix=/seq/.../SOFTWARE/hgaprec LDFLAGS="-L/seq/.../SOFTWARE/hgaprec/ARPACK/"

make: g++: error: CreateProcess: No such file or directory

I see that this issue has been posted many many times but none of solutions worked for me and my problem is a bit different.
The problem:
When a use a makefile and mingw32-make, I get the error:
g++: error: CreateProcess: No such file or directory
However, if I copy/paste the SAME command that the makefile tried to do and paste it in the SAME command prompt it works. This problem only occurs when I try to build with a makefile.
Here's more info:
g++ ./src/main.cpp ./src/application.cpp -I C:\Code\infographie\Labs\inc -L C:\Code\infographie\Labs\lib -I C:\Code\infographie\Labs\inc -g -Dmain=SDL_main -L C:\Code\infographie\Labs\lib -lmingw32 -lSDL2main -lSDL2 -o bin/debug/labs.exe
g++: error: CreateProcess: No such file or directory
makefile:23: recipe for target 'all' failed
mingw32-make: *** [all] Error 1
As I said, If I copy/paste the first line it will work.
What can I try?
UPDATE: I've installed cygwin, adjusted SDL libs and recompiled. Now I get this error when I try to use make. If I copy/paste the command, it works.
g++ ./src/main.cpp ./src/application.cpp -I C:\Code\infographie\Labs\inc -L C:\Code\infographie\Labs\lib -I C:\Code\infographie\Labs\inc -g -Dmain=SDL_main -L C:\Code\infographie\Labs\lib -lcygwin -lSDL2main -lSDL2 - mwindows -o bin/debug/labs.exe
make: g++: Command not found
make: *** [makefile:23: all] Error 127
FIXED IT, don't declare a variable named PATH...
Stop using MinGW.
MinGW has not been updated since 2013. It has been replaced by Cygwin and
MSYS2. The MinGW project doesn’t even offer a 64-bit compiler.
Cygwin can be installed in about 3 minutes, I would give it a try.

Error linking with mingw compiler using Codelite, can't find lib folder

I'm trying to get started with SDL and trying to compile a 'hello world' starter app to check my configuration and I get this error:

The directory C:/Users/Me/Documents/Cpp_Projects/SDL2/32bit/lib/ certainly does exist and has the required SDL libraries in it, but I have no clue about compilers.
This is predefined code which should work so the problem is in set up somewhere?
The -l compiler flag is adding a library dependency. It does not specify a path in which to look for libraries (that is the -L flag), which appears to be what you are expecting.
In your error message:
-L. -lC:/Users/Me/Documents/Cpp_Projects/SDL2/32bit/lib/
You can see that the compiler is looking in your current working directory (.) for the library C:/Users/Me/Documents/Cpp_Projects/SDL2/32bit/lib/, but this is not a library -- this is the directory in which you're storing the SDL libraries.
In the CodeLite linker setup you want to change your library path to C:/Users/Me/Documents/Cpp_Projects/SDL2/32bit/lib/, or use
-LC:/Users/Me/Documents/Cpp_Projects/SDL2/32bit/lib/
as a build flag.
You also need to link to the SDL2 library, so you'll need to add -lSDL2 (possibly -lSDL2main as well, I can't remember the specifics of the SDL libraries) to your build/linker flags.
