Porting software to FreeBSD 5.2.1

Mon Apr 12 02:55:13 PDT 2004

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

 hope this helps a bit to understand what is happening with the post 
program. 

 still working on my side.

I recieved the following answer from the creator of this software:

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.
