Hi, This is a new ELF patch, 1.28.elf, for Linux 1.2.8. It makes Linux 1.2.8 compatible with both ELF and a.out formats. I fixed a few bugs in driver/scsi/53c7,8xx.c. I added the ELF module support. You need modules-1.1.87.5 or newer to use it. You can edit arch/i386/Makefile to choose which binary format you want to compile the Linux kernel in. I only tested it on my machine. I also added the kernel ELF core dump, which is taken from the patch made by jeremy@sour.sw.oz.au (Jeremy Fitzhardinge). I think there may be an ELF bug somewhere: --foo.c-- #include main () { const char * const sd1 = "1.8976931348623157e+308"; *sd1 = 1; } ---- I cannot get it core dump under ELF if I use -static. This bug has been fixed for the next kernel release. You also need a gdb patch to read the ELF core dump. I think if everything goes well, we should be able to totally move to ELF real soon. This patch needs the following packages from me: 1. binutils 2.5.2l.15 or newer. 2. libc 5.0.3. 3. gcc 2.6.3/ELF. The primary ftp sites for the compiler/C library are tsx-11.mit.edu under pub/linux/packages/GCC and sunsite.unc.edu under pub/Linux/GCC. After applying the patch, you can compile the kernel in ELF: # cd linux # gzip -dc ...../linux-1.28.elf.diff.gz | patch -p2 # make zImage The resulting arch/i386/boot/zImage is compiled in ELF. After editing arch/i386/Makefile, you can compile the kernel in a.out. H.J. hjl@nynexst.com 05/20/95
