Generate a make file from a Codeblocks project

[ragnatic]

I really don't know how to generate a makefile from a Codeblocks project so it can be executed in other SOs. Like programming in Arch Linux and running this code in Ubuntu. That's my particular case.

I've been searching and I found this http://irrlicht.sourceforge.net/forum/v ... ke#p256038 and the comment of bitplane is not very clear for me. Besides, there's irrBuild http://sourceforge.net/projects/irrbuild/ but I'm afraid to say that I don't know how it can help me.

I'm getting some success with cmake but I'm having some problems

This is my folder

Code: Select all

 
Project 
    -CMakeLists.txt 
    -main.cpp
    -Irrlicht
        -include
        -source
        -bin/Linux
     -bin
        -CMakeLists.txt
        -actual binary file

These are my CMakeLists files. First the one in the project folder

Code: Select all

cmake_minimum_required(VERSION 2.6)
project(PROJECTUNO)
 
#There are lots of scripts with cmake
#for finding external libraries. 
#see /usr/local/share/cmake-2.6/Modules/Find*.cmake for more examples
find_package(OpenGL)
find_package(X11)
find_package(ZLIB)
 
set(CMAKE_CXX_FLAGS "-g -Wall")
add_subdirectory(bin)
 
 

And this in the bin folder

Code: Select all

include_directories(
  ${PROJECT_SOURCE_DIR}/Irrlicht/include
  ${PROJECT_SOURCE_DIR}/bin
  ${X11_INCLUDE_DIR}
  ${GLUT_INCLUDE_DIR}
  ${ZLIB_INCLUDE_DIR}
  ${OPENGL_INCLUDE_DIR}
)
link_directories(${PROJECT_BINARY_DIR}/Project)
 
add_executable(Project main.cpp
)
 
target_link_libraries(Project
  ${X11_LIBRARIES}
  ${GLUT_LIBRARIES}
  ${ZLIB_LIBRARIES}
  ${OPENGL_INCLUDE_DIR}
  ${PROJECT_SOURCE_DIR}/Irrlicht/lib/Linux/libIrrlicht.a
)
 
 

When I run cmake I get this warning

WARNING: Target "Project" requests linking to directory "/usr/include". Targets may link only to libraries. CMake is dropping the item.

and when I run make I get a bunch of errors like these

This "libraries" folder doesn't even exist.

I used these tutorials

The errors are because you don't link opengl, that's -lGL. By the way Irrlicht comes also with a Makefile - and additionally you could probably get CodeBlocks running in ArchLinux I guess (although I never tried that one).

pacman -S codeblocks

Thats it.

I'm trying to generate a make file from a Codeblocks project that uses Irrlicht. I'm trying to generate a static library which is done, as in IrrCompileConfig says

// To build Irrlicht as a static library, you must define _IRR_STATIC_LIB_ in both the
// Irrlicht build, *and* in the user application, before #including <irrlicht.h>

I have a #define _IRR_STATIC_LIB_ before #include <irrlicht.h> in my main but I'm not quite sure where is this "Irrlicht build" place.

Edit: Well, I saw a static build option in irrlicht codeblocks project located in the source folder. That build has the _IRR_STATIC_LIB_ flag and it seems that I'm all set. But now I get this when I'm compiling my project after getting the make file with cmake

undefined reference to `createDevice'|

Do you link to Irrlicht?
