  2. Re: Linker inlcusion error with ./configure in cross compilation

    Oops, I missed something in your first post.

    Instead of LDFLAGS=-llibdaemon
    use LDFLAGS=-ldaemon

    Normally, the linker knows that the library name starts with "lib" and ends with ".so". And,...

    You need a cross-compiled library. It seems unlikely that is what you have installed.

    Depending on what is typically done for your cross-compile, your system may already have typical steps for...

    Re: Good C++ editor for beginners

    I've never used gedit for programming, but it is built-in to Ubuntu and is supposed to be friendly since it is GUI-based. It probably understands C++ syntax, but I'm not sure.

  11. Re: Getting error while compile classic ladder as Library

    My guess is that you're missing some header file.
