Compiling Irrlicht under Linux (Ubuntu)

IceLink · Post by **IceLink** » Sat Jul 14, 2007 6:47 pm

Hey there, i want to compile Irrlicht from the source/Irrlicht-dir, so i went to this dir and typed "make". I get errors like

Code: Select all

CIrrDeviceLinux.cpp:217: Error: »XF86VidModeSwitchToMode« wasn't defined in this scope
CIrrDeviceLinux.cpp:218: Error: »XF86VidModeSetViewPort« wasn't defined in this scope
make: *** [CIrrDeviceLinux.o] Error 1

What to do? (i've got x11-common)

Comment out the following line in 'include/IrrCompileConfig.h':

Code: Select all

//#define _IRR_LINUX_X11_VIDMODE

thanks-a-lot. At the end, i get

Code: Select all

cp libIrrlicht.a ../../lib/Linux

So, but ifi want to 'make' one of the examples, i get

Code: Select all

Makefile:29: Building...
g++ -I../../include -I/usr/X11R6/include -O3 -ffast-math main.cpp -o ../../bin/Linux/01.HelloWorld -L/usr/X11R6/lib -L../../lib/Linux -lIrrlicht -lGL -lGLU -lXxf86vm -lXext -lX11
/usr/bin/ld: cannot find -lIrrlicht
collect2: ld gab 1 als Ende-Status zurück
make: *** [all_linux] Error 1

(the last but one line might mean that ld told that we came to the end or so)

Does the .a file exist? And did you move the examples directory somewhere else?

IceLink · Post by **IceLink** » Sun Jul 15, 2007 11:52 am

the .a-file exists in "/home/martin/irrlicht-1.3.1/source/Irrlicht", i didn't move anything

it's looking for the .a file in your ../../lib/Linux directory.. are you sure you did a 'make' on Irrlicht itself successfully? If so, in your Irrilcht make file, where is it writing the .a file to?

I find it best to SVN over the code and then do a sudo make - I use sudo cause it's in a 'restricted' directory.

i've got the file "Linux" in /home/martin/irrlicht-1.3.1/lib what'd be ../../lib/Linux and my file-browser notices it as a-file. so, it's existing.

'Linux' should be a directory with a file named 'libIrrlicht.a' in it.

i renamed it and put it in the dir Linux i created, now i get when making

Code: Select all

/usr/bin/ld: cannot find -lXxf86vm

EDIT: got the package xorg-dev, made, works, thanks

You can also just remove the '-lXxf86vm' from the example Makefile, it works fine without it.

what would be the differences?

If you still have the compile config flag disabled as you were told in one of the first posts there is no difference, it's just linking less libraries. But if you reenable the compile flag you can use full screen apps with Irrlicht.
