CmakeLists is not linking to boost_system correctly

Hey Folks,

Just thought I'd give this a shot there... not sure if I should post in support or programming, but programming seems better. I am trying to compile an example program in ogre 3d. here is the cmakelist:

it configures and generates just fine in cmake-gui and even shows that i have boost 1.5.2 installed
however mingw32-make gives this error:

has anyone in windows successfully managed to link to boost_system?
Was going to try install in cmakelists and possibly adding another path variable, but
thought I would ask here first.

tried adding a path variable with the name boost_system and that didn't work.
adding the boost directory to mingw's dir also hasn't worked so far.
man ld in windows... ok well work continues.

I remember having all sorts of issues linking to boost when I tried this last year.  I can't remember exactly what I did, but in the end I think I resorted to printing where CMake expected boost to be (Boost_INCLUDE_DIR) from inside the script, then moving all the built boost files there, as it didn't seem to listen to any environment variables I set.

Incase it helps, here's my Find Boost section (somewhat modified from the ogre tuts):

Spoiler:

and a FindBoost.cmake module I found somewhere... I'm really not sure if I used this or not in the end (warning - very long spoiler):

pastebin link as this was too long for the forum

Sorry I can't help more, it's been far too long since I've looked at this to know exactly what I did.  Nimbal set up an automated build system for us which seems far more effective than what I'd done, so he may be able to help (or check out his/thrives git repo).

There are several issues that could cause the linking error. First, this link command looks suspicious:

Code:

TARGET_LINK_LIBRARIES(
    [...]
    boost_system ${BOOST_LIBRARIES}
)

Usually, you wouldn't add boost_system manually, it should be contained in BOOST_LIBRARIES already.

Second, have you tried printing out BOOST_LIBRARIES to check whether it contains anything at all? I'd bet that it's empty, because the FindBoost module sets the variable Boost_LIBRARIES and CMake is case-sensitive for variable names.

Third, try invoking find_package like this:

Code:

find_package(Boost COMPONENTS system REQUIRED)

Lastly, if FindBoost actually finds something, it should print something like this during configuration:

Code:

-- Boost version: 1.52.0
-- Found the following Boost libraries:
--  chrono
--  date_time
--  filesystem
--  thread
--  system

Oh, and one last question, just to be safe: You have compiled Boost, right?

First thank you for both of the responses, I am about to try Nimbal's idea right now. Sergeon I actually have your old cmakelists file and copied a few things from it.

TARGET_LINK_LIBRARIES(
   [...]
   boost_system ${BOOST_LIBRARIES}
)

this was actually added after getting the error to see if setting a variable named boost_system might do something. I will remove it.

Lastly, if FindBoost actually finds something, it should print something like this during configuration:

Code:

-- Boost version: 1.52.0

Mine only prints out that first line, I am not seeing the other components, will check again in a second though.

and the new error is:

Boost version: 1.52.0
CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.
Missing variable is:

CMake Error: Error required internal CMake variable not set, cmake may be not be built correctly.

The following Boost libraries could not be found:

boost_system

No Boost libraries were found. You may need to set BOOST_LIBRARYDIR to the
directory containing Boost libraries or BOOST_ROOT to the location of
Boost.
Call Stack (most recent call first):
CMakeLists.txt:13 (find_package)


Configuring incomplete, errors occurred!

I really need to go through a tutorial on cmakelists before asking any more questions, I believe I set the variables using:

SET (BOOST_LIBRARYDIR ${BOOST_LIBRARYDIR} "C:/Boost/lib")

but the ${foo} variable is a cache variable or something?

ok solved part of it, you can not call find_package() before project()

so now getting:

Boost version: 1.52.0
CMake Error at C:/Program Files/CMake 2.8/share/cmake-2.8/Modules/FindBoost.cmake:878 (file):
 file FILE([TO_CMAKE_PATH|TO_NATIVE_PATH] path result) must be called with
 exactly three arguments.
Call Stack (most recent call first):
 CMakeLists.txt:18 (find_package)


Boost version: 1.52.0
Found the following Boost libraries:
 system
Configuring incomplete, errors occurred!


BTW yes I believe I compiled Boost, i remember bjam.bat and my boost directory is 1 gig, however it might have compiled incorrectly.

Is this line

Code:

SET (BOOST_LIBRARYDIR ${BOOST_LIBRARYDIR} "C:/Boost/lib")

still in your CMakeLists.txt? If yes, this could be the cause of the error, because FindBoost expects BOOST_LIBRARYDIR to be a single value, not a list of values.

LOL! You solved it. I am really sorry, I need to learn a little more about the problems firsts. anyways, about to generate we'll see.

and i am getting this:

but the boost_system error is gone. will google these errors etc in a little. my boost compile might be bad.
BTW is it possibly because I have boost 1.5.2 and the tutorial was written for an older boost?

hmm according to stack overflow I need to link in boost_system...

ok well my other ogre tutorial, the updated clean ogre cmake project just made it through make with no errors. I just to replace the included find_package with the one you gave me, but it threw an error during mingw32-make install
it can't find a .DLL so i will try to find it and copy it where it wants it.

and OgreApp.exe compiled!
it gives an error though that OIS.dll is not installed on my computer?
so many problems with OIS

and it kinda sorta works. open to a window that asks if i want to use Directx or OpenGL neither one though when it goes fullscreen actually displays the ogre head, it does show the fps and such.

THANK YOU! BTW for the help tonight. It was really amazing to actually compile a c++ project on my own pc.
