suse 8.1 help!

[dlmo78]

I installed suse on a laptop that I was given. The os installed just find my problem is installing anything else. I purchased "SUSE Linux," by Cris Brown,and wnet through the steps for a source code install. on the program that I'm trying to install I get "error 1" messages (3 times) at the end of the make command. The last lines look like this:

osiscg.cpp: In member function 'virtual bool
sword::OSISCGI::handleToken(sword::SWBuf&, const char*,
sword::BasicFilterUserData*>':

osiscg.cpp:102: 'isdigit' undeclared (first use this function)

osiscgi.cpp:102: (Each undelcared identifier is reported only once for each function it apppears in.)

make[2]: *** [osiscgi.o] Error 1

make[2]: Leaving directory '/home/dlmo78/build/sword-1.5.9/utilities/diatheke'

make[1]: *** [all-recursive] Error 1

make[1]: Leaving directory '/home/dlmo78/build/sword-1.5.9/utilities'

make: *** [all-recursive] Error 1

#

(I put spaces to show separate lines and # is back to prompt) When I tried to install the example program, at the end of the ./configure command I get:

checking for perl... /usr/bin/perl

checking for Qt... configure: error: Qt (>= Qt 3.2) (library qt-mt) not found. Please check your installation!

For more details about this problem, look at the end of config.log

Make sure that you have compiled Qt with thread support!

I need help on what these errors mean. I'm new to Linux and I finally found a computer for the disk that was given to me a few years ago.
