jwSMTP Howto

How To Use the jwSMTP library in your own programs

The easiest way to use jwSMTP is to use the pkg-config program. Chances are this is already on your system. As an example you have a file (myemailingprogram.cpp) that you wish to compile into an smtp enabled program ( Please note that the [ ` ] character in this line is not a [ ‘ ] character ). Just run at the command line

g++ myemailingprogram.cpp -o myemailingprogram `pkg-config --libs --cflags jwsmtp-<version>`

where <version> is the latest version of jwCGI without the <> symbols.
This compiles the program myemailingprogram, drop this file in a directory somewhere in your path, simple huh

One caveat this pre-supposes that the PKG_CONFIG_PATH environment variable is set correctly. If not set it at the command line. Please note that the [ ` ] character in these lines is not a [ ‘ ] character.

PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
g++ myemailingprogram.cpp -o myemailingprogram `pkg-config --libs --cflags jwsmtp-<version>`

where <version> is the latest version of jwSMTP without the <> symbols.
/usr/local/lib/pkgconfig being the path to the pkg-config directory where jwSMTP’s pkg-config file is. Alternatively if you do not have the pkg-config program

g++ myemailingprogram.cpp -o myemailingprogram -I/usr/local/include/jwsmtp-<version> -L/usr/local/lib -ljwsmtp-<version>

where <version> is the latest version of jwSMTP without the <> symbols.
If you wish to link statically

g++ myemailingprogram.cpp -o myemailingprogram -I/usr/local/include/jwsmtp-<version> /usr/local/lib/libjwsmtp-<version>.a

where <version> is the latest version of jwSMTP without the <> symbols.
