TextClock C++ Documentation

Guide to compiling, installing, and using the TextClock C++ CGI program.

This page provides detailed technical documentation for the compiled C++ version. For the Perl version, see TextClock Perl documentation.

System Requirements

Unix/Linux operating system
C++ compiler (g++ 3.x or later recommended)
Apache web server with CGI support
Server Side Includes (SSI) enabled
Shell access for compilation

Compilation Steps

Extract the archive:

tar xzf textclock-cpp.tar.gz
cd textclock-cpp

Compile the program:
```
g++ -O2 -o textclock textclock.cpp
```
Test the binary:
```
./textclock
```
Should output the current date and time.

Install to cgi-bin:

cp textclock /usr/local/apache/cgi-bin/
chmod 755 /usr/local/apache/cgi-bin/textclock

Usage Examples

Use the same SSI syntax as the Perl version:

<!--#exec cgi="/cgi-bin/textclock"-->

<!--#exec cgi="/cgi-bin/textclock?format=%A,+%B+%d,+%Y"-->

<!--#exec cgi="/cgi-bin/textclock?format=%I:%M+%p"-->

Performance Optimization

Compile with -O3 for maximum optimization
Use static linking if available: -static
Strip debugging symbols: strip textclock
