libstdc -6 dll not found

Question

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        EDIT       Here are the Build options in my project  Note that these are the settings in the Project  not the global compiler   In  project name - Compiler settings- Otehr options    I use    to seperate the commands   -mthreads   -fmessage-length 0   -fexceptions   -fident     In  project name - Compiler settings-  define   WIN32    WINDOWS     In  project name - Linker settings- Other linker options   -static-libstdc     -static-libgcc   -Wl --enable-auto-image-base   -Wl --add-stdcall-alias   -Wl --enable-auto-import     In linker- link libraries i have various links to files with a  a extension  these files include Bullet PHysics  Ogre3D  and SFML  In the search directories i have links to the MinGW bin  and the MinGW lib directories  along with other links to different libraries   My Compiler is MinGW  a GNU GCC compiler for windows 32 bit  and the IDE is Codeblocks  Also note that in Debug and Release settings on the project  there is nothing   Most of these setings are also pieces that i got from the Ogre3D Application setup tutorial if that is of any help

useful to windows users who use eclipse for c/c++ but run *.exe file and get an error: "missing libstdc++6.dll"

4 ways to solve it

Eclipse ->"Project" -> "Properties" -> "C/C++ Build" -> "Settings" -> "Tool Settings" -> "MinGW C++ Linker" -> "Misscellaneous" -> "Linker flags" (add '-static' to it)
Add '{{the path where your MinGW was installed}}/bin' to current user environment variable - "Path" in Windows, then reboot eclipse, and finally recompile.
Add '{{the path where your MinGW was installed}}/bin' to Windows environment variable - "Path", then reboot eclipse, and finally recompile.
Copy the file "libstdc++-6.dll" to the path where the *.exe file is running, then rerun. (this is not a good way)

Note: the file "libstdc++-6.dll" is in the folder '{{the path where your MinGW was installed}}/bin'

I placed the libstdc  -6 dll file in the same folder where exe file is generated

I just had this issue   I just added the MinGW bin directory to the path environment variable  and it solved the issue

If you are using MingW to compile C   code on Windows  you may like to add the options -static-libgcc and -static-libstdc   to link the C and C   standard libraries statically and thus remove the need to carry around any separate copies of those  Version management of libraries is a pain in Windows  so I ve found this approach the quickest and cleanest solution to creating Windows binaries

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 gt  gt bin folder to where my  cpp file was saved

As far as I know  this is the C   Runtime Library  So it depends on the compiler you use to create your program  A new version will include some C  0x stuff  an older version will probably not for instance  It depends of the compiler and of its version    If you use MinGW then you should use the libstdc  -6 dll found into the folder of this compiler  MinGW bin folder should be the place to search for it on your computer   If you copy this file in the same directory as your executable  it should be OK

I use Eclipse under Fedora 20 with MinGW for cross compile  Use these settings and the program won t ask for libstdc  -6 dll any more   Project type - Cross GCC  Cross Settings    Prefix  x86 64-w64-mingw32-  Path   usr bin   Cross GCC Compiler   Command  gcc All Options   -I usr x86 64-w64-mingw32 sys-root mingw include -O3    -Wall -c -fmessage-length 0 Includes   usr x86 64-w64-mingw32 sys-root mingw include   Cross G   Compiler   Command  g   All Options  -I usr x86 64-w64-mingw32 sys-root mingw include -O3    -Wall -c -fmessage-length 0 Includes   usr x86 64-w64-mingw32 sys-root mingw include   Cross G   Linker   Command  g   -static-libstdc   -static-libgcc All Options  -L usr x86 64-w64-mingw32 sys-root mingw lib -L usr x86 64-w64-mingw32 sys-root mingw bin Library search path  -L      usr x86 64-w64-mingw32 sys-root mingw lib   usr x86 64-w64-mingw32 sys-root mingw bin

This error also occurred when I compiled with MinGW using gcc with the following options   -lstdc   -lm  rather than g     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

Simply removing libstdc  -6 dll a   libstdc   dll a from the mingw directory fixes this    I tried using the flag -static-libstdc   but this did not work for me  I found the solution in  http   ghc haskell org trac ghc ticket 4468

You only need to add your  mingw-install-directory  bin  to your Path in your System environment variables     that s it
