I try to compile a source file which include the <regex.h> with i586-mingw32msvc-gcc:
$ i586-mingw32msvc-gcc parser.c -Ilibregex/include -o parser.o
And I get this:

collect2: ld returned 1 exit status
My folder libregex/include contains the regex.h.
Has anyone tried to compile a source containing <regex.h> with mingw in cross compilation?
Try adding #define PCRE_STATIC before including pcreposix.h.
add -lregex
which works fine with msys2 w64-x86_64

(FYI Yes I do know that a similar question exists, But I have already tried all the answers.)
I'm trying to setup SDL2 with MinGW and I have everything set up beside one thing. Whenever I try to compile G++ gives no errors but then LD gives me a: undefined reference to SDL_Init Error.

I have tried to move the args around. doing -mwindows, adding -lmingw32. I still keep getting the same errors.. I was able to fix the WinMain Error.. But everything else I couldn't fix.

If i could get any help that would be amazing
The common cause of mysterious undefined reference errors on MinGW is using libraries compiled for x64 with an x32 compiler, or vice versa. SDL ships both x32 and x64 ones, try the other ones.
I was able to fix the WinMain Error
Be aware that the intended way of fixing undefined reference to WinMain#16 is not adding #define SDL_MAIN_HANDLED and not doing #undef main. Once you get the right libraries (see the first paragraph), the error should disappear by itself.
Make sure you use int main(int, char**) (and not int main() nor void main()), otherwise it won't work.
-ID:C:\MinGW\include -LD:C:\MinGW\lib
You shouldn't need those flags. Those directories will be searched automatically.
Since you didn't specify any other directories, I assume you placed the SDL files directly into the compiler directories, which isn't a good practice, IMO.
I assume D:C: a typo?
-mwindows
The only purpose of this flag (that I know of) is to prevent your app from automatically opening a terminal window for itself, for release builds.
I am developing c++ application in Win7 OS using GCC compiler and Code::Blocks as IDE. I have everything set up and everything works. Now i need to move whole development environment to virtual machine so i have installed system, IDE compiler, copied whole project. I double checked all libraries and options and they are same. When i try to build application i get this errors (50) from build log(relevant parts):

As you can see, I am using LibHaru library which works flawlesly in guest system. Also i believe problem is not in library itself but in linker.
Project build options -> Linker settings -> Link libraries:
libcomdlg32.a
libgdi32.a
libuser32.a
libshlwapi.a
..\..\CustomLibraries\lpng1636-build\libpng16.a
..\..\CustomLibraries\zlib-1.2.11-build\libzlibstatic.a
..\..\CustomLibraries\libharu-RELEASE_2_3_0-build\src\libhpdfs.a
libcomctl32.a
I tried to do the same thing in Win7 virtual machine with same results. I am using same files as in guest system. Any ideas what went wrong?
I posted this question because i was not sure about linker settings being ok but since nobody said that its wrong i searched for other problems. So it turns out that i have been using wrong Program Files in Global compiler settings -> Toolchain executables. Also library order was wrong, LibHaru needed to be first and then other dependent libraries. Uninstalled GCC and IDE then installed correct version of GCC + IDE. Now it compiles without problem.
I suspect that reinstalling the compiler might have changed the version of MinGW, and maybe the library isn't compatible between these 2 versions.
I've had similar weird behaviour with MinGW before, and recompiling the dependencies myself with the same compiler fixed the issue (it's a tedious solution though).
Are the compiler and system exactly the same ? (same architecture, version, etc)
Check if you havent copied some codeblocks environment specific files from the previous system, maybe codeblocks is trying to compile with options that doesn't apply to your new environment.
Does the libhpdfs headers have system dependent defines ?
Did you compile libhpdfs.a yourself ?
Did you try recompiling it yourself on the virtual machine ?
I am fairly new to Fortran and this may sound like a silly question. I encounter an error when compiling the Fortran code that is posted as an example in the NLOPT Wiki.
I compile in Ubuntu 18.04 LTS using the following command:
gfortran example-nlopt.f90 -o example-nlopt -I/usr/local/include/
The following error is produced in the terminal:

Based on what I saw in nlopt's documentation (https://nlopt.readthedocs.io/en/latest/NLopt_Installation/#changing-the-installation-directory) it looks like you just need to specify the library to link against. Maybe try this:
gfortran -I/usr/local/include/ -L/usr/local/lib example-nlopt.f90 -o example-nlopt -lnlopt -lm
This assumes you have the libnlopt.so in /usr/local/lib, if not then point to its location with the -L option.
Overview
I am attempting to convert a C++ project from a Visual Studio solution to a makefile project (using g++), as a first step to supporting multiple platforms with ease. This project requires the Simple DirectMedia Layer 2 (SDL2) and SDL_image libraries. The project previously compiled without errors, and I have since corrected any errors halting the g++ compiler. I am still using Windows x64 and MinGW x64 at this point.
Problem
When linking, g++ throws errors as though there is something wrong with the SDL2 library, claiming that all functions of SDL2 can't be found. However, I know it is finding the libraries, because when I provide an incorrect name or path, I get an explicit error.
Here is my new makefile, apologies if it isn't up to standard:

Troubleshooting
I have tried a number of things from supplying exact paths to libraries to updating SDL from 2.0.3 to 2.0.4. The behavior is the same. There are two include/lib folders in the MinGW devel folder for each architecture, and changing which one I include does not make a difference.
There seems to be a lot of commotion about the order of which arguments are supplied to g++, given the three posts below:
SDL2 Undefined references to functions
Try to change the sequence of the input params:
I've stumbled over this before (on Linux)
https://askubuntu.com/questions/68922/cant-compile-program-that-uses-sdl-after-upgrade-to-11-10-undefined-reference
Ok, solved. Apparently, for some mysterious reason, the order of the gcc options now matters.
http://smf.cataclysmdda.com/index.php?topic=11028.0
It looks like the SDL2_image library is included, but the main SDL2 library is not (the references could be out of order).
Unfortunately, regardless of how I have reordered the arguments, I can't seem to change this result. Unlike with most issues, I haven't even been able to make it any worse! Any and all help is greatly appreciated.
I don't believe this has anything to do with my code, considering a compile without linking -c completes fine, but if it assists with the solution I would be more than happy to post some of it (it is a LOT of code).
Edits
Per request, here is a dump of the full compile with the -v and -Wall options. It is too large for this question so I threw it in a pastebin.

Thanks to suggestions from #J.JHakala and #user657267 I have reached the conclusion that my installation of MinGW is actually 32 bit! Given that I was using the 64 bit libraries, they would read in like any other library, but the functions within them were not recognized.
For anyone else having this problem, you can download the 64 bit version of MinGW or alternatively just switch which libraries you are importing.
x86: i686-w64-mingw32
x64: x86_64-w64-mingw32
I have a simple openGL D program that compiles, but I can't get it to link with libglut.a. I've tried a few different command lines:
$ dmd life.d -lglut
$ dmd life.d -L-lglut
$ dmd life.d -L/usr/lib/libglut.a
$ dmd life.d /usr/lib/libglut.a
All of these print the following errors:
life.o:(.data+0x10): undefined reference to `_D1c2gl4glut12__ModuleInfoZ'
life.o:(.data+0x14): undefined reference to `_D1c2gl2gl12__ModuleInfoZ'

Is there a problem with my command lines, or is it something else?
Those look like mangled symbols from D code. You mentioned on your previous question that you were using some kind of compatibility layer – did you make sure to include the files or libraries from that in your build?
