I installed gcc, ld, the libraris, etc from Linux Slackware 96 into=20
/compat/linux. I built hello world. When I tried to run it, it core=20
dumped.
I am running FreeBSD 2.2-CURRENT built Thu Sep 19 07:50:53.
I've narrowed the problem down to program being statically rather than=20
dynamically linked. I could not force linker to dynamically link the=20
program.
The linker distribued with SLackware 96 is
$ ld -v
ld version cygnus-2.6 (with BFD 2.6.0.14)
If I replace the Slackare 96 linker with an older version. I can link=20
dynamic programs and hello world works. I backed the linker out and=20
replaced it with
$ ./ld -v
ld version cygnus/linux-2.5.2l.17 (with BFD cygnus/linux-2.5.2l.11)
Has anyone seen this problem? Is it a slackware problem or an emulation
problem?
$ gcc -v -Ddynamic -o hello hello.o
Reading specs from /usr/lib/gcc-lib/i486-linux/2.7.2/specs
gcc version 2.7.2
ld -m elf_i386 -dynamic-linker /lib/ld-linux.so.1 -o hello /usr/lib/crt1.o=
/usr/lib/crti.o /usr/lib/crtbegin.o=20

.o /usr/lib/crtn.o
$ ./hello

$ ldd hello

Also, each time hello is ran, it creates an odd-named file in the current=
=20
directory. The same file is added each time the program is ran, although=
=20
the file may have differnt modes.
$ ls
