#69 libgcc_s-dw2-1.dll is missing


tdm64-gcc-4.6.1.exe was downloaded and all components were installed.
However, after fortran programs were compiled,
I could not use a program due to an error:
"The program can't start because libgcc_s_dw2-1.dll is missing from your computer.
Try reinstalling the program to fix this problem."

Would you help me with this "libgcc_s-dw2-1.dll" issue?

    Other than a few experimental LLVM test toolchains, mingw-w64 does not use dw2, so it is unlikely this error is related to mingw-w64 itself.

    I get the exact same error. Here is what I do to reproduce it. I installed the CodeBlocks then MinGW compiler. I create a console app using the default, "Hello World," code. It builds the debug and the release version as I asked for it to do. It runs fine from within the IDE but when I try to run either the Debug or the release version it comes up with the same error message.
    Any thoughts? Thanks
