"This application has failed to start because the libgmp-3.dll was not found"



  • Hi I am trying to build a project on an XP platform using cmake 2.8, with QT 4.7.4 and the MinGw compiler provided in the SDK download for my c and c++ compiler. For some reason I get the message "This application has failed to start because the libgmp-3.dll was not found", even though it is in my QtSDK\MinGW\bin directory. Anyone have any suggestions?
    Thanks



  • please run "sysdm.cpl' in any commnad prompt(or your can access it from contol panel), go to advanced tab, click environment variable button, and modifiy environment variable 'PATH' to have it that path as item.
    it is the only way to change 'PATH' variable permenantly.



  • Forgot to include that QtSDK\MinGW\bin was included in my path. Could there be something wrong with the dll?
