binary compatibility on alpha

[dawe]

Hi pals, sorry for a new message (but in this way I can split your answers into two threads!). I installed Gentoo on a alpha ds25 (running 2.4.30 kernel). Now I would like to run some 32bit x86 apps. I see that em86 is not into the portage tree and also ftp.digital.com is no more available...

thanks

Of course... my browser has some problems with ftp... also from the shell I have Unknown host for ftp.digital.com...
Thanks a lot

I have problems in compiling em86 on my alpha...

em86-0.4 $ make
cc -g -O0 -w -I. -DEM86_RUNTIME -c -o sys_mmap.o sys_mmap.S
gcc -c -g -O0 -w -I. -DEM86_RUNTIME -I/usr/x86/include -DUSE_FX_CPU em86.cc -o fx_em86.o

em86.cc:288: error: in argument to unary !

I'm not the best person to patch the code... Also I couldn't find any README or whatever... The installation docs only say something about rpm and I cannot have a rpm working here.

I've tried the binaries, the rpms and srpms too (after all I used Firefox...).
Now that I can run rpm I tried to install them but:
# rpm -ivh em86-0.4-1.alpha.rpm
error: Failed dependencies:
libm.so.6.1 is needed by em86-0.4-1
libdl.so.2.1 is needed by em86-0.4-1
libc.so.6.1 is needed by em86-0.4-1
ld-linux.so.2 is needed by em86-0.4-1

and I have to give --nodeps as option. I can install
em-x86-0.2-1.i386.rpm but then:

# rpm -ivh --force em86-baselibs-0.2-1.alpha.rpm
Preparing... ###########################################

/usr/bin/ldconfig86
error: %post(em86-baselibs-0.2-1) scriptlet failed, exit status 139

that's because ldconfig86 goes into segmentation fault.
I see there is a patch for the kernel but, you know, is for kernel 2.0 and I'm running 2.4... maybe I should try another way but bochs doesn't seem to be able to run single executables and qemu won't install (I tried to modify the ebuilds, but it doesn't compile).
