Where is the output of the configure stored? THe config.log is empty.
I am using Linux-Mandrake 7.2. I have sucessfully used gd 1.8.1 to
draw on web pages by streaming to stdout in a "C" program.

I now wanted to add labels, vertical and horizontal axises, and tick
marks. Thats when I started looking at plplot. I thought I could
plot on png images and send the output to stdout or to a temp file.

The gd libraries are in 
/usr/lib
The gd headers are in 
/usr/include
The gd.c code was compiled by make into gd.o so it must have found the
headers. 

[root@search plplot-5.0.3]# find . -name "gd.*"
./drivers/gd.c
./tmp/shared/gd.o
./tmp/gd.c
./tmp/gd.o          

The plplot doesnt recognise the "png" keyword or so the error
says. 

[root@search plplot-5.0.3]# tmp/x01c | more
Plplot library version: 5.0.3
Requested device png not available   

How can I get it to recognise
plsdev("png"); 
correctly in my "C" code?

Thanks.

Martin
