SPARK2 libpugixml errors

Messages : 7 Date d'inscription : 2012-03-25

Hello,

I compiled latest version of SPARK2, but when I try to use the following

Code:: SPK::IO::Loader* loader = new SPK::IO::XMLLoader();

I get build errors:

Thank you for the report. This bug is already known (and is on my todo-list Wink

).

Do you use gcc via command line or Code::Blocks ? Maybe you could try to add libpugixml to the list of libs to link. Normally, it is generated in SPARK_2_DIR/external/pugixml/bin.

There is a bug in the CMake script that affect only gcc generator (and MinGW generator), the lib seems to be built when needed (normal behavior) but the script fails to indicate the correct path to the lib.

I used command line to build the project. (Linux - GCC 4.4.5)
Both libSPARK.a and libpugixml.a are build succesfully according cmake.

If I add pugixml to the libraries for the GCC linker, I still get the same error Crying or Very sad

Is there another workaround ? So I can atleast test SPARK2 in my project Very Happy

EDIT:

Managed to build my test project by changing the order of the libraries:
SPARK_IRR
SPARK
pugixml

I noticed the correct linking order is very important!

Thnx for the quick reply

Ok, thank you, I think you corrected the bug! I checked on the net and saw that GCC linker uses a very stupid algorithm in 1 pass, thus I must change the link order and add externals at last.

Will test it further.
