First steps in using system ssl: compiling a program

System SSL also known as GS kit provides an API for doing

• TLS handshakes
• Keyring manipulation
• Encryption and signing of data

See First steps in using system ssl gives some introductions to gskit.

The blog post provides the script I used to compile my programs. Not everything may be relevant.

name=main 
export _C89_CCMODE=1 
p5="-I.  -I/usr/include " 
p7="-Wc,DLL " 
p8="-Wc,LIST(c.lst),SOURCE,XREX,SHOWINC" 
p8=" "  # no listing
/bin/xlc $p5  $p7 $p8  -c $name.c -o $name.o 
l1="-Wl,LIST=ALL,MAP,XREF         " 
bind=" /usr/lib/GSKCMS31.x /usr/lib/GSKSSL.x " 
/bin/xlc $name.o ${bind}  -o $name -v $l1 1>bind.lst 

The output from the C compile goes into c.lst, and from the bind it goes into bind.lst

The gsk includes are in /usr/include.

For the bind you need /usr/lib/GSKCMS31.x /usr/lib/GSKSSL.x
