Hi,

I have just downloaded Apache 2.2.4, compiled it, installed it
and the tried running it. What I get when I call:

./apachectl start

is:

./apachectl: line 102: 12799 Segmentation fault      $HTTPD -k $ARGV

and if I call:

./httpd

directly, then I get:

Bus Error

Could you run

ulimit -c unlimited

before you start the server? It should dump core in /cores. Then, run

gdb httpd -core `ls -t /cores | head -1`

and when gdb has finished loading, execute the bt command (bt ==  

backtrace). Send us the output of the bt command (#0 all the way  

through the line that says 'in main ()').

Followed the above instructions starting httpd with as 'httpd -k  

start' and

then ran gdb with the core (there was only one in the /cores folder):

ghostwalker:/Library/Apache2/bin root# gdb httpd -core /cores/core.3584

Core was generated by `./httpd'.

I think it's --with-layout=Something. Anyway, I don't think we have  

a layout called ServLog in config.layout. What are you trying to  

achieve there?

It was so the install path of Apache was in /Library/Apache2:

#   Classical Apache path layout.
<Layout ServLog>
    prefix:        /Library/Apache2
    exec_prefix:   ${prefix}
    bindir:        ${exec_prefix}/bin

    mandir:        ${prefix}/man
    sysconfdir:    ${prefix}/conf
    datadir:       ${prefix}
    installbuilddir: ${datadir}/build
    errordir:      ${datadir}/error

</Layout>
