dlclose@@GLIBC_2.2.5

[Joseph Smith]

Hello,
No matter if I use qemu from the serialice repo or download the tarball 
and apply patches i get this weird build error:

CC    x86_64-softmmu/disas.o
   CC    x86_64-softmmu/i386-dis.o

Anyone else seen this? What in the heck is dlclose@@GLIBC_2.2.5 ???

Your lua library was linked against libdl, and linking of serialice
doesn't seem to include that when linking.

If lua installs a .pc it'd be good to use $(pkg-config --libs lua) in
the serialice Makefile.

Actually it didn't. I installed it from source. I had to include it:
export PKG_CONFIG_PATH=/home/joe/cboot/lua-5.1.4/etc/

This is a bit wacky....

Ok. Maybe now there is a recent enough version of lua available as
package for your distribution? (Or maybe someone can make one?)
That'd make things easier.

yes, FC14 does have a lua-5.1.4 rpm.... but it doesn't have the 
serialice patches....so I need the source....

Hmm, it is in qemu configure, shouldn't that be enough?

LUA_CFLAGS=`pkg-config --cflags lua`
     LUA_LDFLAGS=`pkg-config --libs lua`

It should, but make install does not install the lua.pc file

You will have to copy it manually. Maybe you could report the bug to lua
upstream maintainers?

Ok, if I copy it manually, where should I copy it to? Where is the 
correct location?

Check where there are other .pc files. On my system (though not
Fedore) the folder is /usr/lib/pkgconfig

Ah ok thanks, looks like FC14 x86_64 uses:

/usr/share/pkgconfig/

and

/usr/lib64/pkgconfig/

Well...log story short looks like I already had the lua rpm 
installed....but I finally figured out I also needed the lua-devel 
package.....That is why I only had half the install.....Curses! Mind 
boggling why they have to split programs in half like that!

Well qemu is building fine now.

My question is if the FC14 x86_64 version of lua probably doesn't have 
the serialice patches installed, does it matter? Will serialice still run?

Not everyone using LUA might want to compile their own stuff with it.. Unfortunately SerialICE is not quite ready to come preshipped with distributions quite yet..

64 bit systems might. If I remember correctly at least one of the patches fixed an issue on 32 bit systems...
