Re: Re: I just installed FLTK on Linux but I have a compile error ken williams 06:58 Oct 22 top right image
  It seems I can't compile it with g++ ...
I tried this:

    g++ hello.cpp -o hello -I/usr/local/include -L/usr/local/lib -lfltk -lXext -lX11 -lm

and I get this:

    /usr/bin/ld: /usr/local/lib/libfltk.a(Fl_X11_Window_Driver.cxx.o): undefined reference to symbol 'dlsym@@GLIBC_2.2.5'
    /usr/bin/ld: /usr/lib/libdl.so.2: error adding symbols: DSO missing from command line
    collect2: error: ld returned 1 exit status

Could someone tell me what I should add or change?
hello.cpp is the one from the FLTK 1.4.0 documentation: https://fltk.gitlab.io/fltk/basics.html

Thank you!

I started with VS on Windows.. but I switched VS Code and now to Linux to force myself to understand more of what's behind the scenes...

As an aside - what does Dr.S recommend to do for compiling stuff in his book?

You said you were following the book, so I wonder what mechanism it recommends...
