How do I fix "/bin/sh: 2: patch: not found" and "make: *** [lib/libcurl.a] Error 127" errors?

curl-loader is a traffic generator. You can generate HTTP, HTTPS, FTP etc. traffic with it.

Add to that, you can simulate multiple clients (multiple source IP addresses).

Here’s an explanation of how to install curl-loader on Ubuntu 12.04 64bit box and generate HTTP, HTTPS traffic.

$ uname –r
3.2.0-39-generic
$ tail -1 /etc/lsb-release
DISTRIB_DESCRIPTION="Ubuntu 12.04.2 LTS"

install curl-loader

1. download curl-loader from
2. I downloaded curl-loader-0.56.tar.bz2.

3. extract

   bunzip2 curl-loader-0.56.tar.bz2
   tar xvf curl-loader-0.56.tar
   cd curl-loader-0.56/

4. build requirements

   Build it using general C development environment with bash, gcc (3 or 4 series), make, etc on a linux machine.

   Building pre-requirements are:

   • openssl binaries;
   • openssl development package with include files (on debian package libssl-dev);

   I have not installed libssl-dev , so I installed libssl-dev before compiling curl-loader.

   sudo apt-get install libssl-dev

5. compile

   $ pwd
   /home/hattori/My_works/curl-loader-0.56
   $ make
   [...]
   /bin/sh: 2: patch: not found" AND "make: *** [lib/libcurl.a] Error 127

How do I proceed from this error?
