[Qemu-devel] Minor bug in 0.7.1 install

[Qemu-devel] Minor bug in 0.7.1 install

[Greg Bell]

hi qemu,

thanks for a neat project.  two minor problems:

1) on my FC3 box, i had to force sdl to compile statically because 
the sdl test didn't work for some reason (could be my box's 
problem).  but there's no way to set sdl = 'yes' from the 
configure command line.  so i hacked configure, but then line 
730 dies:

             echo "SDL_LIBS=$sdl_static_libs" >> $config_mak

this is because $sdl_static_libs evaluates to a multiple word string on my 
system.  eg:

$ sdl-config --static-libs
-L/usr/lib -lSDL -lpthread -lm -ldl -lasound -L/usr/X11R6/lib -lX11 -lXext

so "SDL_LIBS=multiple word thing" is an error.


2) i needed to chmod 777 /usr/local/share/qemu/ before i could run qemu as 
a normal user.

My config.mak has this multi-word line (for dynamic SDL)

		SDL_LIBS=-L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread

and it works fine. I'm not sure why its not working for you. At least its not
the length, as I have longer LIB lines which work (tho none of them are static).

Assuming its owned by root:root, chmod 555 should be enough (mine is currently
set to 755).

$config_mak is a makefile fragment, not a shell script, so this should work 
fine.

hmmm... configure errors out for me after i hack it to force static 
linking with SDL and this is what i traced it to.  here's the actual 
output rather than my possibly flawed analysis :)

This is not sufficient as a lot of the SDL logics is contained in the if 
block you have now disabled.. you need to also at minimum set sdl_config, 
sdl_static and sdl_static_libs accordingly.

I am a little curious about what exacly you are attemptig to do. SDL is by 
default linked statically if your SDL installation supports static 
linking..

What is the output of "sdl-config --static-libs" on your system? Prehaps 
your SDL is not built with support for static linking?

Henrik

I think this is your original problem.. for SDL to be linked statically 
qemu must be linked statically.

Try going back to the original version and simply add --static to your 
configure line..
