Hi All: Am trying to modify a code in order to run it in FreeBSD, this code was intendend for Linux only, after several days modifying code a mannaged to compile it "successfully" and ended with a binary, called "post" this program is a client side of a systema called BhPos, the server side is working ok, but this client is dying every time with a segmentation fault. debugging the core file from the post excecution I found the following: terra# gdb /usr/bin/post GNU gdb 5.2.1 (FreeBSD) Copyright 2002 Free Software Foundation, Inc.

Eric. I recieved the following answer from the creator of this software: Re: Still can't get client to connect to server Sun, 11 April 2004 11:19 You probably know that libc is the library that includes all the standard C commands (such as printf, read, open, etc.and so on) as well as system calls. Up until 1997, the only library available was the GNU libc v1, which since the move to ELF binary format was given major number 5 (/lib/libc.so.5). In 1997, the Free Software Foundation developed GNU libc v2, with the intention of being cleaner, more portable, and more standard (POSIX compliant). Under Linux, this version got major number 6, hence it's called libc6. These two libraries are incompatible - if a program is compiled with one libc's headers and stubs, it can't be used with the other. any one knows how i can use the libc6 in the linux compat directory? i have checked on my sistem and in fact i have it! /usr/compat/linux/lib/libc.so.6 thanks in advance for your help on this. ---
