Irrlicht Engine

Posted: **Tue Oct 08, 2019 7:34 pm**

I downloaded irrlicht-1.8.4 on Windows, went into source/Irrlicht and run make win32 because I want to compile the sources with MinGW.
I get this error:

Code: Select all

g++ -Wall -pipe -fno-exceptions -fno-rtti -fstrict-aliasing -g -D_DEBUG -I../../include -Izlib -Ijpeglib -Ilibpng -DIRRLICHT_EXPORTS=1 -DNO_IRR_COMPILE_WITH_DIRECTINPUT_JOYSTICK_ -DNO_IRR_COMPILE_WITH_DIRECT3D_9_ -DIRR_COMPILE_WITH_DX9_DEV_PACK -D__GNUWIN32__ -D_WIN32 -DWIN32 -D_WINDOWS -D_MBCS -D_USRDLL  -c -o CIrrDeviceWin32.o CIrrDeviceWin32.cpp

<builtin>: recipe for target `CIrrDeviceWin32.o' failed
make: *** [CIrrDeviceWin32.o] Error 1

How can I resolve this error?

I commented the lines of code where there is _strcmpi (in hope that I will not need this piece of code) then the compilation continues. I run make staticlib_win32 because I would like to try to make a static compilation. I get the file ../../lib/Win32-gcc/libIrrlicht.a of 55 Mo but when I try to use it:

Code: Select all

g++ -static -mwindows -I../../include ../../lib/Win32-gcc/libIrrlicht.a main.cpp -o ex01.exe
/tmp/cciRcIRh.o:main.cpp:(.text+0x76): undefined reference to `createDevice'
collect2: error: ld returned 1 exit status

What did I do wrong?

Somehow you compile in strict ansi mode. But I'm not quite sure why as I don't see it from your compile-flags. It happens when people compile with -std=c++0x instead of -std=gnu++0x (so often the case when trying to use c++11), but you set neither. Maybe newer g++ somehow has that as default now? Which g++ version are you using. I'm testing here currently with g++ 6.3.0 on MinGW, which I guess is somewhat outdated.

The other error - yeah it doesn't link. Not sure if you can set relative paths for linker. Usually you set the path with -Lpath and then only use the name like -lIrrlicht (without lib and .a). Maybe that's it (thought I would expect other errors then...).

use strcasecmp in its place on linux

MinGW should be using the Windows API, not unix and this function is only used in the Win32 device. But I guess we could just get rid of it there and use our core::stringc class (it's not a speed relevant place anyway). No need to keep a potential problem around for 3 lines which can be done otherwise.

edit: All uses of _strcmpi are now removed from the engine (r5962, will be in Irrlicht 1.9).
