Linking problem when using files from other project

Post by spert »

Hi,

First, Thanks to Eran and everybody else working on this IDE. It is really nice you put so much effort into it and also support multiple operating systems!

System Information:

Code: Select all


OS:      : Windows 7, 64 Bit
CodeLite : version 7.0 , 64 Bit 
                - codelite-amd64-7.0.exe from the homepage) 
                - installed to folder C:\Program Files\CodeLite
Compiler : Mingw 4.8.1
                - installed to folder C:\MinGW-4.8.1
General Information:
I made a workspace proc_space ( located at C:\cpp_projects\proc_space ) which contains two projects:
  • game
  • game_test
folder-structure inside proc_space folder:

Code: Select all

game project setup:
I use the standard template library and SFML 2.2 ( located at C:\dev_libs_cpp\SFML-2.2 )

In the game project the subfolder Debug is created (see contents below):

Code: Select all

    .d
    Game.cpp.o
    Game.cpp.o.d
    game.exe

To run the game I need to add the sfml dlls but I omit that part here.

Here the problems start :roll:


game_test project setup:
In the game_test project I want to test certain functionality of project game.
I use the Unittest++ (located at C:\UnitTest++-1.3 ) and again SFML 2.2 ( located at C:\dev_libs_cpp\SFML-2.2 )

TEST(Test_QuadTree)
{
	QuadTree qt = QuadTree(0, sf::Vector2f(0.0f, 0.0f), sf::Vector2f(512.0f, 512.0f));

There is no CHECK used right now but that does not matter.

cannot find -lQuadTree.cpp.o
I tried to change the Library in the configuration to QuadTree.cpp.o.d but it gave me a similar error. I also tried to compile game project in Release configuration (that's why also the Release folder is in the linker folders of game_test project) before running the game_test build.

Do I perhaps miss something?

Thanks for any help, suggestions. I hope I didn't paste too much text. :oops:

Why are you messing with the objects directly? You should not attempt to pass an object file (e.g. QuadTree.cpp.o) directly to the linker using the "-l" switch
You should remote this completely. The linker will not find it because it is not a library

Re: Linking problem when using files from other project

Post by spert »

That's a very good question. Thanks for pointing this out. That was actually a pretty stupid move. Thanks! :roll: :oops:

I was able to solve my problem by creating another project ( dll) in my workspace called game_libraries where I moved all classes like QuadTree, Entity, etc. and then link to it in my game and game_test project. So when I compile the game_libraries project and link to it's Debug-path from game and game_test it works fine.


Another question if I may?

When I added Tests directly to the main.cpp in game_test it worked fine.

Then I created a separate file using the context menu to create a specific test file (in a subdirectory "tests" for QuadTree (named test_QuadTree) which contains auto generated test cases for all methods in class QuadTree.

Compilation of game_test works.

After I click on the "run tests button" in the IDE it I get a message box saying "Project contains 0 tests. Nothing to be done." .

Do I need to add something to the main.cpp in game_test to also run the tests in test_QuadTree.cpp ?

main.cpp contains currently:

Code: Select all

#include <UnitTest++.h>

// run all tests
int main(int argc, char **argv)
{
	return UnitTest::RunAllTests();
}
Output of the game_test build:
