the ebuilds need to include the '--enable-shared --enable-static' flags to be passed to configure for the libggi, libgii and libsdl packages so that other applications such as qemu can compile correctly, this is not the only application but just one that is in portage that can be built if these flags are set. I have manually added these lines to the myconf variable in the ebuilds on my test system, re-emerged those packages and now ALL of the applications I have been trying to compile and use work. Reproducible: Always Steps to Reproduce: 1. 2. 3.
could you ... oh i dont know ... provide some more useful information ? :P qemu builds just fine over here with those packages and ive never heard anyone report this 'kind' of problem with libsdl before in fact, if you look at the output of `./configure --help` you'll see that both shared and static are enabled by default: --enable-shared[=PKGS] build shared libraries [default=yes] --enable-static[=PKGS] build static libraries [default=yes]

Hi. Can you re-open this bug with the following additional info? I unmasked qemu-0.5.5-r1 to try this newer version and failed to compile it due to a linkage error. While searching for already existing bug-reports I found this one which may be related. Specifically, compilation fails at the following point: ================================ CUT gcc -static -Wl,-T,/local/var/tmp/portage/qemu-0.5.5-r1/work/qemu-0.5.5/i386-vl.ld -o qemu-fast vl.o osdep.o block.o monitor.o ide.o ne2000.o pckbd.o vga.o sb16.o dma.o oss.o fdc.o mc146818rtc.o serial.o i8259.o i8254.o pc.o gdbstub.o sdl.o slirp/cksum.o slirp/if.o slirp/ip_icmp.o slirp/ip_input.o slirp/ip_output.o slirp/slirp.o slirp/mbuf.o slirp/misc.o slirp/sbuf.o slirp/socket.o slirp/tcp_input.o slirp/tcp_output.o slirp/tcp_subr.o slirp/tcp_timer.o slirp/udp.o slirp/bootp.o slirp/debug.o libqemu.a -lm -L/usr/lib -Wl,-rpath,/usr/lib -lSDL -lpthread -lm -ldl -lasound -L/usr/X11R6/lib -lX11 -lXext -lvga -lutil /usr/lib/libSDL.a(SDL_loadso.o)(.text+0x1b): In function `SDL_LoadObject': : warning: Using 'dlopen' in statically linked applications requires at runtime the shared libraries from the glibc version used for linking /usr/lib/gcc-lib/i686-pc-linux-gnu/3.3.3/../../../../i686-pc-linux-gnu/bin/ld: cannot find -lasound collect2: ld returned 1 exit status make[1]: *** [qemu-fast] Error 1 make[1]: Leaving directory `/local/var/tmp/portage/qemu-0.5.5-r1/work/qemu-0.5.5/i386' make: *** [all] Error 1 ================================ CUT Maybe the original reporter got confused by the SDL-related warning, but if you look at the output the real error is related to no being able to link against libasound (ALSA).

During the build, I noticed the following output in the very begining: ================================ CUT dawn portage # emerge qemu Calculating dependencies ...done! >>> emerge (1 of 1) app-emulation/qemu-0.5.5-r1 to / >>> md5 src_uri ;-) qemu-0.5.5.tar.gz >>> Unpacking source... >>> Unpacking qemu-0.5.5.tar.gz to /local/var/tmp/portage/qemu-0.5.5-r1/work >>> Source unpacked. softmmu qemu-fast Install prefix /usr BIOS directory /usr/share/qemu binary directory /usr/bin Manual directory /usr/share/man ELF interp prefix /usr/gnemul/qemu-%M Source path /local/var/tmp/portage/qemu-0.5.5-r1/work/qemu-0.5.5 C compiler gcc make make host CPU i386 host big endian no target list arm-user i386-user ppc-user sparc-user i386-softmmu ppc-softmmu i386 gprof enabled no !!! --> static build no SDL support yes !!! --> SDL static link yes mingw32 support no ================================ CUT Notice the lines marked with "!!! --> " above. As you can see there are 2 parameters for static/shared linkage for qemu. In short (I'm not very familiar with ebuilds but...) I think that qemu should check if the static USE flag is set and disable both "static build" and "SDL static link". Anyway, I insisted on trying to find a USE flags combination that works for qemu. I therefore re-emerged libsdl setting USE=static to make sure that no conflicts among SDL and ALSA exist due to emerging the static ALSA _after_ SDL (which was already on my system) but I still get the same last error. Finally, I tried to emerge qemu with USE="-sdl -static" but this did not seem to disable SDL support for QEMU.
qemu-0.6.0 emerged just fine for me ... give that a run and i'll review the system specific info on my machine versus yours
Some more info on this. It could be a bug in libSDL. See this posting on the QEMU mailing list: http://lists.gnu.org/archive/html/qemu-devel/2004-04/msg00021.html

libsdl(1.2.7-r2) also fails when both qemu-fast and sdl are active.
so this has nothing to do with sub libraries and everything to do with qemu
qemu-fast will be disabled soon, the linker script it uses is at least problematic...
Sorry was out of the country for a while the problem stems from the libsdl package not making static libraries. It currently only makes dynamic libraries. Changing the ebuild file to pass the static and dynamic build parameters to configure fixes the problem.
