I'm trying to run fltk "Hello World" program in Dev-C++ and when i compile it, the following error comes. The compile log is

Re: linker error

Welcome to GIDForums™ unpep. There are a number of people that wander through here that use Dev-C++. Post your code for your test1 program and perhaps something will jump out at us.

The other thought is that you are not properly linking to the fltk library (linker settings in your IDE) for some of the later errors.

Re: linker error

You can set up which libraries to include in DevC++ using Project->Project Options and going to the 'Parameters' tab.
Add the appropriate library using the same format as those already present in the box.

Also check to make sure DevC++ points at the correct 'includes' and 'libraries' directories under the 'Directories' tab in the same dialogue box.
