Wt

Hi,

New to Wt (and C) and having massive difficulty projects to compile. Have been at it all day and am loosing the will to live :)

I can get a simple "hello_world" type program to compile and run, so I can't be doing everything wrong, but I'm now trying to take the Auth1 example and starting bending it to my will. I've changed the name of the project, but nothing else.

Compilation seems to fail at the linking stage with a whole load of errors that make it seem like there must be a missing library or something? I've checked and double checked and randomly tried all sorts of things.

If anyone has any suggestions, they would be gratefully received.

Below is my CMakeLists.txt along with the a few lines of make errors.

Platform is Ubuntu 12.04. I can compile the examples with the CMakeLists.txt in the examples folder, but I can't get any of them to compile individual (even if I edit their CMakeLists.txt files)

1. tell cmake what it should link your executable to
   TARGET_LINK_LIBRARIES (sophont.wt
   ${WT_LIBS} ${BOOST_LIBS} ${WT_DBO_LIBS}
   )

<!-- -->

1. tell the linker where all these libraries should be searched for
   LINK_DIRECTORIES (
   /usr/local/lib
   /usr/lib
   )

<!-- -->

1. tell the compiler where it should look for extra include files
   INCLUDE_DIRECTORIES(
   /usr/local/include/Wt
   /usr/include/boost
   )
