1.5 Win32/gcc build error

rogerborg · Post by **rogerborg** » Wed Dec 03, 2008 12:08 am

I did, and now I have Code::Blocks as well.

Right, SVN 1909 on the 1.5 branch restores the 1902 functionality: IdentityMatrix is declared but not defined with IRRLICHT_API.

I have tested this with both MSVC and mingw via Code::Blocks. I've added a test case for it, and a Code::Blocks test project (/tests/tests.cbp) which all works as expected.

The Code::Blocks project(s) also seem screwed up. Irrlicht_Win32-gcc.cbp didn't define __GNUWIN32__, so Irrlicht.cpp failed to compile due to trying to #include <crtdbg.h>

I've added that definition, which also updated Irrlicht_Win32-gcc.cbp to the C::B 8.02 version. ( <FileVersion major="1" minor="6" /> ). Apologies if this screws anyone over, but I don't fancy maintaining an older format by hand when I'm not familiar with it. We can always revert it if it causes problems.

The C::B example projects (or at least the Hello World one) look for libIrrlicht.a in ../../lib/Win32-gcc, which is peculiar as Irrlicht cbp builds that library in ../../bin/Win32-gcc. I won't update those yet until you C::Bers have a chance to shout out.

cool, i'll switch from trunk to branch 1.5 then.
and now i'll have to fix all the damn stuff again =.=

Sorry about the inconvenience, but until we get 1.5 released, you should consider it to be the de facto development trunk. All of the fixes are going on to 1.5 first, and are only moved to the trunk in batches.

I'm trying to get my SConstruct file working, but I'm having a couple of problems with it :\

I've added the flag for __GNUWIN32__ which, as you said, fixed the crtdbg problem, but I'm still getting the

Code: Select all

Irrlicht.cpp:44: error: external linkage required for symbol 'irr::core::Identit
yMatrix' because of 'dllexport' attribute.

error.

Adding the _IRR_STATIC_LIB_ flag gives me these errors:

I'm using the mingw compiler on Windows.

Any ideas?

Well, I figured out what was wrong

The patch is below, and it's also in the tracker:

Great, thanks. We already have winmm on the 1.5 branch, but I've added the __GNUWIN32__ flag in SVN 1921.

Can I suggest that you use the 1.5 branch for now, since all the fixes are going there.

wyrmmage · Post by **wyrmmage** » Sat Dec 06, 2008 4:10 pm

Thanks for the quick commit! I'll have to remember to use the 1.5 branch

I'm trying to compile the Irrlicht 1.5 sdk (from the zip file and from svn) using mingw32 under windows xp.
I go to the source folder, and run

Code: Select all

mingw32-make sharedlib

However I get the following error:

Code: Select all

Irrlicht.cpp:12:22: crtdbg.h: No such file or directory
Irrlicht.cpp: In function `BOOL DllMain(void*, DWORD, void*)':
Irrlicht.cpp:61: error: `_CRTDBG_LEAK_CHECK_DF' was not declared in this scope
Irrlicht.cpp:61: error: `_CRTDBG_ALLOC_MEM_DF' was not declared in this scope
Irrlicht.cpp:61: error: `_CrtSetDbgFlag' was not declared in this scope

Irrlicht.cpp:61: warning: unused variable '_CRTDBG_ALLOC_MEM_DF'
Irrlicht.cpp:61: warning: unused variable '_CrtSetDbgFlag'

apparently it can't find crtdbg.h, which really is not in the source directory. How do I fix this?

Just read what was said above, and fix the Makefile accrodingly. If you cannot do that, you have to switch to the SVN-branch which has this already fixed, or you use an IDE which does the proper defines for you.

Hi,

Thanks for the reply, but I've tried that.
I have checkouted the 1.5 branch, applied the patch, but still get that message.

What is going wrong?

hybrid · Post by **hybrid** » Thu Mar 05, 2009 9:34 am

The branch doesn't need a patch, at least that was the idea. I've moved the define to another place in the project file, please try again with revision 2253.

jonim8or · Post by **jonim8or** » Mon Mar 09, 2009 12:24 pm

It appears the file crtdbg.h is supplied with visual studio. But I don't use visual studio, so I don't have the file. How can I get the crtdbg.h file for mingw?

hybrid · Post by **hybrid** » Mon Mar 09, 2009 1:54 pm

You simply don't need it. Just clean up your defines and everything should compile as expected.

jonim8or · Post by **jonim8or** » Tue Mar 10, 2009 10:02 am

I've found it. I hade to explicitly tell it to make windows version, otherwise gnuwin would not be set.

Code: Select all

mingw32-make win32

Then it gave another problem: the makefile uses cc as compiler, but the mingw compiler is called gcc. renaming the compiler, compiling and renaming back works as a one-time solution, but there should probably be a better one.

thanks for the help.
