Dear Dominik, I copy the whole file folder "lapackpp_lib" to the directory where main.exe is, but the same error message is shown. Do I have to change the path of lapackpp_lib in the makefile? Thank you. Sincerely, changtsan On Wed, November 16, 2011 11:28, Dee wrote: Dear changtsan, You link lapackpp-Library dynamically to your main.exe. This means everybody who wants to start main.exe needs to have the lapackpp-Lib somewhere in his execution path. The easiest way tol solve this is to copy the library in the same directory as the exe. Then the programm should execute fine.
