compile error version 1.1.5, gcc 3.3.1

[Christian Fischer]

hi there,

today i've compiled version 1.1.5 taken from sourceforge.net on two different 
machines.
as first on athlon xp, Linux version 2.4.20-gentoo-r7, gcc version 3.2.3 
(Gentoo Linux 1.4 3.2.3-r1) - with no problems.

as second one on intel p4, Linux version 2.4.20-gentoo-r7, gcc version 3.3.1 
(Gentoo Linux 3.3.1-r1) - with the following result:

/usr/X11R6/lib/libXxf86vm.so: undefined reference to `XextAddDisplay'
/usr/X11R6/lib/libXxf86vm.so: undefined reference to `XextFindDisplay'
/usr/X11R6/lib/libXxf86vm.so: undefined reference to `XextCreateExtension'
/usr/X11R6/lib/libXxf86vm.so: undefined reference to `XextRemoveDisplay'
/usr/X11R6/lib/libXxf86vm.so: undefined reference to `XMissingExtension'
collect2: ld returned 1 exit status
make[1]: *** [/root/dosemu-1.1.5/1.1.5.0/bin/dosemu.bin] Error 1
make[1]: Leaving directory `/root/dosemu-1.1.5/src'
make: *** [default] Error 2

can anybody tell me what's wrong? can i work around?

these functions are supposed to be in libXext.so
Check your Makefile.conf; it should say something like
LIBS=-lXxf86vm -lXext -lX11  -lslang -lm -ldl
perhaps
LIBS=-lXext -lXxf86vm -lXext -lX11  -lslang -lm -ldl
helps? In any case this doesn't appear to be a gcc problem.

it looks like
LIBS=-lXxf86vm -lX11  -lslang -lm -ldl
in my case
LIBS=-lXxf86vm -lXext -lX11  -lslang -lm -ldl
helps

well, why
LIBS=-lXxf86vm -lX11  -lslang -lm -ldl
works on my gcc3.2.3-machine?

I think you're just lucky on your gcc 3.2.3 machine -- perhaps -lXxf86vm
or -lX11 automatically link the -Xext symbols.

The configure script will use -lXext if mitshm is enabled. For some reason
you're not using mitshm -- check config.log and the configure output.

But the unlikely case of not wanting mitshm but wanting xf86vm
(vidmode) should be handled anyway -- so the configure script needs to be
fixed.
