Since one of the potentially more useful aspects of tomsrbt is the ability to add your own programs to the disk, I thought I'd share my experiences trying to get stuff to compile for tomsrtbt. It turns out that the major distributions these days are glibc (libc6) based while tomsrtbt, for space reasons, is based on the previous release of libc for linux, libc5. This means that programs you compile on your regular linux box will *not* work on tomsrtbt. I spent a day or so reading various HOWTO's and old news postings and my options seemed to come down to this: 1. Create a cross compiler from scratch. The compiler would run on your libc6 system, but produce the libc5 binaries which tomsrtbt requires. In order to do this, you need to get and compile the source for *both* libc5 as well as gcc. As far as I can tell there is no FAQ that tells you how to do this. The best resource I found describes the reverse process (i.e., create a glibc cross compiler on a libc5 system), but the principles are the same and the pointers to the files you need are current. You can find Frodo Looijaard's page at: http://huizen.dds.nl/~frodol/glibc/index.html 2. Try to get gcc to cross-compile using command line switches. WARNING! I never got this to work personally, before I found a better way, but here's my best guess. Note that for this to work you need to have the libc5 header files somewhere on your system. In my case, the distribution I use (Redhat 5.2) did *not* supply these files. The directories listed here are for my system and will probably be different on yours. /usr/bin/gcc -nostdinc \ /*the directory which contains the libc5 header files. If you don't have these files, read on! */ -I/usr/i486-linuxlibc5/include \ /*the directory which contains the header files specific to your version of gcc*/ -I/usr/lib/gcc-lib/i386-redhat-linux/2.7.2.3/include 3. The easy way! Since a number of people have faced this problem before, you'd think there be a pre-compiled package you could just download. After scouring newsgroups I came across a pointer to a libc5 cross compiler rpm for Redhat. It turned out that I actually needed three separate packages: 1. The gcc cross compiler for libc5. 2. A binary version of the library, libc5, so I could test programs on the same machine I compiled them on. 3. The libc5 header files (very important and not supplied on Redhat 5.2) These packages, created by Christopher Seawood, can be had at: http://developer.redhat.com/rhcn/browse/conventional/packageinfo.p hp3?package=gcc-libc5 http://developer.redhat.com/rhcn/browse/conventional/packageinfo.p hp3?package=gcc2.7 http://developer.redhat.com/rhcn/browse/conventional/packageinfo.p hp3?package=libc5 Good luck!
