I develop C++ programs using a Cygwin installation on top of Windows XP.
I also have MinGW installed, because I want to use it's version of g++, not the one that comes with Cygwin.
That part seems to be set up correctly. When I start a Cygwin session I see this:
$ which g++
/cygdrive/c/MinGW/bin/g++
This is correct, g++ is pointing to my MinGW install.
What I don't understand is when I write code that includes library code (for example, header files from the `Winsock/BerkleySockets API), how can I tell where the compiler is finding that header file?
For example, if I have #include "winsock.h" in my code, where does the compiler find that header file?
If I do a general search for winsock.h on my computer, I get this:
C:\MinGW\include
C:\cygwin\usr\include\w32api
Both have a copy of winsock.h (though the file sizes of these aren't exactly the same, so they can't be identical).
Thanks for the help.
I should also point out, I have the C:\MinGW\bin in my Windows PATH Environment Variable, as well as that same path configured in my/etc/profile file within Cygwin.
I'm guessing the g++ compiled for MingW has the same command line arguments as the standard g++. Check out the g++ manual page.
To add include paths to your compilation, use the -I flag.
g++ -I/include/path/here -I/another/include/path -o prog src.cpp
To add library paths to your linking, use the -L flag.
g++ -L/lib/path/here -L/another/lib/path -o prog src.cpp
The MingW site explains how the include file search works on MingW, and how to modify it.
The site also says that if you want to view the include file search while it happens during the compilation, pass the verbose flag (-v) to the compiler.
g++ -v -o prog src.cpp
I believe it's referring to the one in MinGW/include. Take a look at the Minigw documentation for include paths.
If you are using an eclipse environment you can specify the include paths in the project settings along with specifying your choice of compiler i.e mingw in your case. Let us know if you still have a problem.

I have been working on a project (a game to be specific) and I feel that I should start over with different libraries. So when doing this I reinstalled Code::Blocks and setup my new libraries and includes.
But as of now Im having a problem starting u[ my new project to test if all of the includes work. This problem is: libstdc++-6.dll was not found. At first i wondered if I could just find this file online, but its nowhere to be found(or at least the many places I have searched...) Soon after, I tried loading up my old project, and the same problem happened again(wierd... ._.) I was thinking its maybe my compiler, so I used my older compiler and it did the same thing! At this moment I held the problem off for tomorrow(which is today)
So my question is: If anyone else had this problem, how would you solve it?
Im using Code::Blocks with MinGW as the compiler on Windows Vista 32 bit.

I did not notice these options, and added: -static-libgcc -static-libstdc++
I still got the error, and finally realized I was using gcc, and changed the compiler to g++ and removed -stdc++ and -lm, and everything linked fine.
(I was using LINK.c rather than LINK.cpp... use make -pn | less to see what everything does!)
I don't know why the previous author was using gcc with -stdc++. I don't see any reason not to use g++ which will link with stdc++ automatically... and as far as I know, provide other benefits (it is the c++ compiler after all).

I had this problem too. I was compiling in command prompt and used the flag -static.

Im learning c++ and I compile from the command line. I have a problem when it comes to trying to add 3rd party libraries. I cant seam to figure out the linker system. Does anyone know a good tutorial or something like that?
For example I want to play around with the SDL2 library and ill use a command like this.
c++ -I/Library/Frameworks/SDL2.framework/Headers -L/Library/Frameworks/SDL2.framework/ -lSDL2 helloworld.cpp
and I get the error ld: library not found for -lSDL2
You need to put the linking flags last on the line:
g++ -I/Library/Frameworks/SDL2.framework/Headers helloworld.cpp -L/Library/Frameworks/SDL2.framework/ -lSDL2
I found out the answer. The following command compiled correctly. The include statement had to be changed to...
#include<SDL2/SDL.h>
and the correct compile command is...
c++ -o helloworld helloWorld.cpp -framework SDL2
I could also have used g++. On my system both c++ and g++ are symlinks to the same gnu compiler which happens to be the latest version I have installed on the system.
the option -L is a unix linker option and does not work on a MAC. The dev's for GCC were kind enough to include MAC specific linker options in the form of -framework. These serve to follow the mac tradition of how and where they like to store libraries. You can link several frameworks together by separating them with a comma. So for example i could also do -framework SDL2,SDL2_mixer as long as my source has
#include<SDL2_mixer/SDL_mixer.h>
When compiling this default search location for libraries is /Library/Frameworks. The include statement is cross platform compatable and the mac gnu linker knows that if I say
#include<SDL2/SDL.h>
that that header will be found at /Library/Frameworks/SDL2.framework/Headers
The -IPATH option still works on mac and can be used to pass alternate search locations for header and source files just like it works in unix.
I have been working on a project (a game to be specific) and I feel that I should start over with different libraries. So when doing this I reinstalled Code::Blocks and setup my new libraries and includes.
But as of now Im having a problem starting u[ my new project to test if all of the includes work. This problem is: libstdc++-6.dll was not found.

I just had this issue.. I just added the MinGW\bin directory to the path environment variable, and it solved the issue.
I placed the libstdc++-6.dll file in the same folder where exe file is generated.
You only need to add your "mingw-install-directory"/bin/ to your Path in your System environment variables ... that's it !!
I had same problem. i fixed it. i was using Codeblocks and i save my .cpp file on desktop instead of saving it in Codeblocks file where MinGW is located. So i copied all dll files from MinGW>>bin folder to where my .cpp file was saved.
You can also copy the dll files in the directory of your exe file
I had this problem too. I was compiling in command prompt and used the flag -static.
My command before:
"g++ test.cpp -o test.exe"
and afterwards:
"g++ test.cpp -o test.exe -static"
I had the same problem and I solved it by running the compiled exe as an administrator.
