Could you give some hints on > installing it on the pc532? I had the same reaction when I first looked at Earl's package :-). If has been a while since I compiled it, so my memory is abit fuzzy as the mechanics, but I believe that attached files should get you started. Right, wrong, or indifferent, the files are the 'config.h' and 'site.h' I used to make the package. I highly recommend Earl's package if you are trying to port *nix code to Minix -- the standard Minix library just has too many limitations. If anyone out there would like to integrate a floating point library, you would be perforing a great service to the group. All the hooks are present, so it shouldn't be to difficult if you are familar with the organization of fp librarys. -- John Connin: manatee Orlando, Florida UUCP: {uunet,ge-dab,ucf-cs}!tarpit!tous!manatee!johnc

Almost forgot folks..... config.h and site.h
/* c o n f i g
*
* Describe system configuration
*
* This file describes the environment under which stdio
* is to be compiled.
*
* The macros that are defined in this file are:
*
* Code control:
*
* DENORMAL
* Provide support for denormalised numbers in _f_cvt().
* ERRLIST
* Use an internal form of sys_errlist for perror().
* FLOAT
* Use float.h.
* HIDDEN
* Hide standard names.
* LARGEPOWERS
* Large power of ten vector found in file lpowers.h.
* LMR
* LDBL_MAX / FLT_RADIX found in lmr.h.
* MEMORY
* Use memcpy(), memset() and memchr(). If this is not defined,
* users must provide definitions for MEMCPY, MEMSET and MEMCHR.
* MYMEMCPY
* Use stdio code for memcpy.
* MYMEMCHR
* Use stdio code for memchr.
* MYMEMSET
* Use stdio code for memset.
* NOFLOAT
* No floating point support.
* OPEN3
* Use open(2) for three argument opens.
* RENAME
* Use rename(2).
* STDARG
* Use stdarg.h instead or varargs.h.
* LIMITS
* Use limits.h.
* SMALLPOWERS
* Small power of ten vector found in file spowers.h.
* STRING
* Use string.h.
* SYSTYPES
* Use sys/types.h.
* TIME
* Use time.h.
* TRUNCATE
* Floating point to integer conversion truncates.
* UNSIGNEDCHAR
* Use (int) ((unsigned char) (x)) for unsigned casts instead
* of (x) & ((1 << CHAR_BIT) - 1).
* UNISTD
* Use unistd.h.
* VOIDSIGNAL
* Signal returns void rather than int.
*
* Stdio performance control:
*
* FREADTHRESHOLD
* FWRITETHRESHOLD
* Threshold beyond which fwrite or fread will use memcpy() to
* do the transfer instead of PUTC().
* MEMSET(s,v,n)
* Set a piece of memory to the specified value.
* MEMCPY(d,s,n)
* Copy a piece of memory of length n from s to d. No return
* value expected.
* MEMCHR(s,c,n)
* Look in a piece of memory s of length n for character c. Return
* a pointer to the c if found, otherwise null.
* TOLOWER(c)
* Convert uppercase to lowercase.

HI, I vote for simplicity, one set of library sources, more beer, less politics.... I have studiously (or is that estudiously) gathered all the postings, and just as carefully avoided putting in any! I would like to use estdio, it is faster, and should continue to be supported in future Minix releases, more than the standard libc. If someone sorts out this mess, I will use it. On another note, I would go for a group buy if the drive uses DC600 tapes. It would be pretty easy to add tape support to my driver. I have been using my SCSI driver (really a modified Bruce's) for a while now, no problems (fingers crossed). I am trying to upgrade to 1.4 (the hybrid). Oh yeh, PC Minix 1.4 was a commands upgrade, with no kernel changes. This is what we have substantially. And, I upgraded my fs to a larger cache size, if anyone out there has not, it is essential. Compilation speed is now amazing. But, look how long a sync takes :-) Has anybody got advice on the relationship between the hash table size and the cache size ? Cheers, Des.
