If you want you can +convert them to an odd ELF executable with: + $ bcc -N -3 prog.c -o prog + $ objcopy -O elf32-i386 prog + +The as86 and ld86 with this are _different_ from the ones needed for the +linux-i386 kernel but can replace them, the kernel-i386 ones _will_ _not_ +work correctly here! + +Unfortunatly, the DOSEMU folks have been using the '-r' option of ld86 +This version does accept '-r' but it generates _LINUX_ a.out object files. +I think they should really be using 'as86_encap'. + +To compile the various tools as Linux-8086 binaries cd into the relevent +directory and do a "make clean ; make" from there. +Bcc _WILL_ now work this way! Yippee! :-) + +I _strongly_ suggest you install the kernel patch or load the module in +the elksemu directory in your Linux-i386 kernel, it makes things _much_ +easier. + +-Rob. |
