installing fung-calc on ubuntu

[Paul King]

I have a little problem with compiling the fung-calc source. Fung-calc
is an online open-source graphing calculator.

I do a ./configure, and I get the following message after it runs
autoconf:

checking for Qt... configure: error: Qt (>= Qt 3.0) (headers and
libraries) not found. Please check your installation!
For more details about this problem, look at the end of config.log.

Let it be said that I have Ubuntu recently recommended an update which I
followed, regarding installing version 4 and version 4 of the "dev"
package. There are files present under /usr/lib/Qt, and /usr/include/Qt
also.

So, checking config.log doesn't seem to be of much help. Doing as I am
told and "looking at the end of config.log" gets me:

------8<-----SNIP-----8<----------

-bash (10) tail config.log 
#define SIZEOF_INT 4
#define SIZEOF_LONG 4
#define STDC_HEADERS 1
#define VERSION "1.3.2b"
#define ksize_t socklen_t
#endif
#ifdef __cplusplus
#include <stdlib.h>

configure: exit 1

------8<-----SNIP-----8<----------
It looks to me like it just "kind of dies" during the configuration.
If you require all of this file to troubleshoot this, let me know, but I
don't believe that there is anything impressive, although there was the
following interesting passage:

------8<-----SNIP-----8<----------
conftest.cc:2:21: error: qglobal.h: No such file or directory
conftest.cc:3:26: error: qapplication.h: No such file or directory
conftest.cc:4:21: error: qcursor.h: No such file or directory

conftest.cc:6:34: error: private/qucomextra_p.h: No such file or
directory

configure: failed program was:

#include <qstylefactory.h>
#include <private/qucomextra_p.h>
#if ! (QT_VERSION >= 300)
#error 1
------8<-----SNIP-----8<----------

And doing a "locate" on these missing files yielded:

------8<-----SNIP-----8<----------
-bash (13) $ locate qglobal.h
/usr/local/src/qt-3.3.4/qt-x11-free-3.3.4/src/tools/qglobal.h

In other words I have several copies of all of the files.

This was after running the commands in the form of:
./configure

and

sudo sh ./configure --with-qt-dir=/usr/lib/qt4
--with-qt-includes=/usr/include/qt4

and also with version 3 libs:

sudo sh ./configure
--with-qt-dir=/usr/local/src/qt-3.3.4/qt-x11-free-3.3.4/include
--with-qt-incdes=/usr/include/qt3

any help would be appreciated.
