</IfModule>




For apache 1.3.x

I have a AMD 2.8GHz box with 1GB RAM and running RH LE3 with Plesk 7.5.4 when I tried to install that module, it failed and gave me the below error

[lexis2004]

I installed this and now when I try to restart I get this:

/etc/init.d/httpd restart: configuration broken, ignoring restart
/etc/init.d/httpd restart: (run 'apachectl configtest' for details)


Any Ideas?

Can you paste the output from configtest.

Use

export CC=/path/to/gcc-x.x

[jwagdy]

this is what I get when I used gcc -v

[root@xxxxxxxx data_admin]# gcc -v

[lexis2004]

I found it, a copy and paste type.

Thanks anyhow.

[jwagdy]

Can any one help?

[Scott.Mc]

export CC=/usr/bin/gcc-3.2.3

and compile, if that doesn't work paste the output of

ls -al /usr/bin | grep -i gcc

[jwagdy]

I did but I got the same error again

[root@xxxxxx mod_evasive]# export CC=/usr/bin/gcc-3.2.3
[root@xxxxxx mod_evasive]# /usr/local/psa/admin/bin/apxs -cia mod_evasive20.c

include -c mod_evasive20.c
sh: line 1: gcc-3.4: command not found
apxs:Break: Command failed with rc=127


What can I do?

[jwagdy]

when I run gcc -v I get the following

[root@xxxxxx mod_evasive]# gcc -v
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/3.2.3/specs
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/u
sr/share/info --enable-shared --enable-threads=posix --disable-checking --with-s
ystem-zlib --enable-__cxa_atexit --host=i386-redhat-linux
Thread model: posix
gcc version 3.2.3 20030502 (Red Hat Linux 3.2.3-53)

so I think I might have gcc installed in different location other than /usr/bin/gcc-3.2.3 am i right?

[Scott.Mc]

Like I said above

ls -al /usr/bin | grep -i gcc
whereis gcc

[Jcink]

Hmm thanks for the tutorial, I really want to install this mod, but I am using windows is there a mod_evasive ported to windows someplace?

I've used this in the passed and it had got all messed up when I had clients with sites that generated images via php. So say a site with a ton of images that are .php then grab the images in order to prevent hotlinking.

So anyone who uses it now have you had any issues like this?
