Newsgroups: comp.sources.wanted Subject: Romable C libraries Summary: Expires: Sender: Reply-To: Matthew Hayden Harper <harper-m@cis.ohio-state.edu> Followup-To: Distribution: usa Organization: Ohio State University Computer and Information Science Keywords: Help!! I have made a program which converts Sun3 C executable files into motorola hex records for my eprom programmer. I am doing this so I can execute C programs on a 68000/68010 board which I have made. The program uses my own startup code to load initialized data segments, and zero out bss (unitialized data segments). I have been successful in doing this with commodore amiga executable files, however there are a few bugs in their compiler so I don't really trust it. However, I have been successful in using the floating point libraries and all of their string and math functions. I then wrote a program which converts a Sun3 executable file (with my startup code linked in) into an amiga executable file. I then run it through my amiga executable to motorola hex records program and everything works until it hits a sscanf function or a ssprintf function, at which time the system bus errors and crashes. I looked at the dependincies of sscanf() and sprintf() in /usr/libc.a and apparantly these functions are linking with some type of buffering system in memory which itself requires malloc(). However, my program uses floating point and did not crash when floating point routines were used, but when I tried to sprintf() the values into a string, the system crashes. The libraries I have for the amiga are already compiled, so I don't have source for them, and I don't trust them enough to convert to sun object libraries because I have found some bugs in a few of the libraries. If anyone has the source for C libraries which doesn't use operating system calls, I would really appreciate it if you could mail them to me (particularly the souce for sscanf and sprintf functions which don't use operating system calls). Also if you know how to cause floating point libraries to be generated completely in software independent of the operating system and a coprocessor with either the cc sun compiler or the gcc sun compiler, I would like to know how to do it (I am currently using gcc with the -mc68000 and -msoft-float options and I am not sure if this is correct). Also if anyone has a Romable C 68000 compiler or a programs which converts a sun3 executable file to any type of hex record, I would appreciate finding out where I could get a copy of the souce. Thank you -=- Matthew Harper

Well, I don't know whether you are talking about the amiga sprintf() function, or the sun one. The Amiga sprintf() can be found in amiga.lib and uses a bss hunk. >If anyone has the source for C libraries which doesn't use operating system >calls, I would really appreciate it if you could mail them to me (particularly >the souce for sscanf and sprintf functions which don't use operating system >calls). Lattice provides source code to their libraries for a nominal fee.

($300 to >$500 I think) Um, nominal to who? $300-500 is nominal to a company trying to make and sell a product, but to a hobbyist that kind of cash is anything but nominal. Wish I made enough to call that kind of money nominal, I'd trade my PC in for a Sun. Yes, I know the hazards/hassles involved in selling source, I just think the phrasing needs to be adjusted. Especially as I consider the Amiga to be a hobbyist machine, whereas PCs tend to be buisness machines. Not that the PC is a superior machine, it just has superior marketing and momentum. -- jim jharkins@sagpd1 "My hope is that we can use tariffs to force Japan to open their markets to imported goods.

Since it sounds like you already have access to an Amiga, you might try using one of the freely redistributable compilers for the Amiga, or rehosting it to another machine. One possibility is the "zc" compiler, based on Sozobon C, which includes full source for the compiler and runtime. This distribution is available on disk 314 of my library for the Amiga (AKA "Fish Disks") widely available from Amiga user groups and dealers.

I am looking for a C cross compiler / assembler for 68000 target to run on a MAC II. This needs to be a professional looking product as it will be used on a DOD project. DonB
