Compiling SPARK 2 on Gentoo Linux

Messages : 7 Date d'inscription : 2011-12-29

Hi there. I just checked out the latest revision of SPARK 2 from the SVN repository.
I fixed most of the compile errors, but I have two left which have me a bit puzzled.

Once I get the library compiling and test it I can check in the changes... so far they are minor and involve things where GCC is more strict than the MSVC compiler.

Anyway, here are the errors:

Code:: ~/projects/spark_allegro/spark/include/Core/SPK_Zone.h:70:117: error: default argument for parameter of type ‘SPK::Vector3D&’ has type ‘SPK::Vector3D’
~/projects/spark_allegro/spark/include/Core/SPK_Zone.h:79:89: error: default argument for parameter of type ‘SPK::Vector3D&’ has type ‘SPK::Vector3D’

And the two lines in question from SPK_Zone.h:

Code:: (line 70) virtual bool intersects(const Vector3D& v0,const Vector3D& v1,float radius = 0.0f,Vector3D& normal = Vector3D()) const = 0;
(line 79) bool check(const Particle& particle,ZoneTest zoneTest,Vector3D& normal = Vector3D()) const;

Hi,

I compiled SPARK under GCC recently (not the last version of the compiler though). Which version of gcc are you using ?

For the issue, it is a problem with Rvalue bound to non const reference. The default value is uniquely used when the normal doesnt need to be read back but it is not really legal (even though VSC does not complain)

The best way to solve the problem would be to replace the non const reference by a pointer with a NULL default value and test the nullity when needed inside the method implementations. The quick hack would be to have a static vector used as a dummy and pass it as the default value to the method. I used that last method in ZoneModifier because gcc was complaining but it is strange it didnt complain for me in Zone.h

What are the other stuff you re talking about you had to modify in the code for it to compile under GCC ?

Yea I realize trying to set a default argument for a non-const reference parameter is illegal, but making the parameters const caused more problems, heh.

The other changes I made are in this diff:

Ok thanks,
I will push a revision on SVN in a few hours that should address all these issues.
I ll let you know when its done

Other than that there are just a lot of errors having to do with the default Vector3D arguments. I don't think it's a good idea to just go through your code and put static Vector3Ds everywhere, but then if I change it to take a pointer I'm not sure how much code that's going to affect. I'm assuming a lot.

Ok I pushed the changes on SVN (including Vector3D& transformed to Vector3D*)
Tell me if there's still some trouble

You fixed everything except one:

Anyway, I'm now having an issue with it not being able to link the pugixml library. I'll keep working on fixing it but here are the errors for now.

EDIT:
Solved it by passing CMAKE_CXX_FLAGS="-fPIC"
This is apparently required on x86_64 machines.

I think it can be added to the cmake file like this (I'm not really sure, I don't have much experience with cmake):

Code:: IF("${CMAKE_SYSTEM_PROCESSOR}" STREQUAL "x86_64")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -fPIC" )

Well your SPARK engine is now compiling nicely.
The OpenGL renderer is not compiling (quite a few strange errors), but at least I can start on the Allegro renderer now, although I'd like to get the GL renderer working as well.

If you have any idea what might cause all these errors, let me know, heh.

Yes, it is a conflict due to a custom stdint.h definition I m using in the project.
Anyway, I dont really need it, so I used a simpler way to define fixed size integer.
Try the latest revision on SVN.

Also in the OpenGL renderer CMakeLists file you are linking with "opengl32" but it should be "GL" on linux (adding a simple OS check would fix that).

One more thing I noticed was the location the library files were placed and the location the CMake files looked for the libraries were different. I ended up doing this temporarily:

Thanks again for your help, although I might need a bit more help getting my renderer working, I'll see. Very Happy

I got the OpenGL demo working as well.

Compiling SPARK 2 on Gentoo Linux Spark_demo

Subject: Re: Compiling SPARK 2 on Gentoo Linux Wed Jan 04, 2012 2:38 pm

Thank you for the report on CMake issues, especially for the 64bit linux related one. I will push the modifications asap.
I will test a 64bit build on my machine, for the moment I'm on Windows 64bit but only compile in 32 bit...

EDIT: The commit I will push will move VC++ and C::B projects in a "deprecated" folder, for final deletion.

Subject: Re: Compiling SPARK 2 on Gentoo Linux Thu Jan 05, 2012 1:06 pm

I've pushed only 3 modifications:
- moving the old projects
- changing the lib name of OpenGL to user-specified. By default, it will take the value 'opengl32' on all platforms except on Linux, where it is defaulted to 'GL'.
- Fixed errors occurring when no Irrlicht lib names are given to CMake.

For the inconsistent library paths, I don't see the source of the problem. Everything works well on Windows 32/64 bit, I've tested it on 3 machines. I currently don't have a Linux machine...
What is your build toolchain ?

Messages : 7 Date d'inscription : 2011-12-29

Thanks for the help.
The inconsistent library paths are my fault. I assumed CMAKE_BUILD_TYPE was already set to some default, but it's not (which makes sense), so once I set it myself it works fine, haha.

I fixed I posted above for the 64bit issues does work since I just tested it.

Code:: IF("${CMAKE_SYSTEM_PROCESSOR}" STREQUAL "x86_64")
SET(CMAKE_C_FLAGS "${CMAKE_C_FLAGS} -fPIC")
SET(CMAKE_C_FLAGS "${CMAKE_CXX_FLAGS} -fPIC")
ENDIF("${CMAKE_SYSTEM_PROCESSOR}" STREQUAL "x86_64")

Although that probably only works for GCC. I'm not sure about the MSVC compiler.
