echo gcc -O2 -include /usr/include/errno.h > conf-...The reason was explained in http://cr.yp.to/docs/unixport.html#errno

Exerpt from bash documentation. HISTORY EXPANSION The bash shell supports a history expansion feature that is similar to the history expansion in csh. This feature is enabled by default for interactive shells, and can be disabled using the +H option to the set builtin command. Non-interactive shells do not perform history expansion by default. History expansions introduce words from the history list into the input stream, making it easy to repeat commands, insert the arguments to a previous command into the current input line, or fix errors in previous commands quickly. History expansion is performed immediately after a complete line is read, before the shell breaks it into words. It takes place in two parts. The first is to determine which line from the history...

You can use the system call from the os module to execute an external program:
>>> import os >>> os.system(the_command_line_st...However, the path to the executable contains a space character, the system call treats the strings after the first space as arguments, causing an error. Python doc recommends the use of the subprocess module: The subprocess module provides more powerful facilities for spawning new processes and retrieving their results; using that module is preferable to using this function. For example, using wget to get the google home page:
>>> from subprocess import Popen, PIPE >>> (out...or
>>> import subprocess >>> subprocess.call(['cur...

Steps to configure SSL for Apache HTTPD server on Windows: In Apache2.2/conf/httpd.conf , load mod_ssl and include httpd-ssl.conf :
LoadModule ssl_module modules/mod_ssl.so ...In Apache2.2/conf/extra/httpd-ssl.conf , make sure the paths for the cert files point to the cert and key you want to use:
# Server Certificate: # Point SSLCertificat...Start up Apache. If it fails, use the command line to see what the error is. There won't be any log in error.log if there are errors in the conf files:
C:\Program Files (x86)\Apache Software Foundation\...I corrected the previous error by using the alternative line for SSLSessionCache :
