Building Plotutils-2.4.1 Under Cygwin

[Ullal Devappa Kini]

Dear Sir,
Some time back, I had downloaded plotutils-2.4.1. I managed to build the
software under Cygwin. Details are given below with the hope that they will
be of use to you. If you do not find the details of interest, I apologize
for wasting your time; please ignore the message.

 

With Best Wishes,

-------------------------------------------

 

Building plotutils-2.4.1 under i686-pc-cygwin:
Cygwin Version 1.3.22
XFree86 Version 4.2
gcc Version 3.2
Windows 98 2nd Edition
Pentium III Processor.

 

Part One.
---------
Try building everything by doing configure and make.
In the Top Source Directory ( /usr/src/plotutils-2.4.1 ) do

 

LDFLAGS="-L/usr/local/lib -L/usr/X11R6/lib " \
CPPFLAGS=-I/usr/X11R6/include \
./configure --x-includes=/usr/X11R6/include --x-libraries=/usr/X11R6/lib \
--disable-shared --enable-static --disable-libtool-lock --with-x \
--with-athena=/usr/X11R6 --with-motif=/usr/X11R6 --with-xpm=/usr/X11R6 \
--enable-ps-fonts-in-pcl --enable-lj-fonts-in-ps --enable-lj-fonts-in-x \
--enable-libplotter --enable-libxmi

 

# Before making, add -Wno-deprecated to CPPFLAGS in
# libplotter/Makefile to avoid unnecessary warnings.

 

make

 

Errors while making the libplotter library.

---------
Delete g_write.cc in libplotter directory. Copy ../libplot/g_write.c to
g_write.cc. Edit g_write.cc to change declaration of c to const char * c
in the above function. Execute the script starting with c++ in libplotter
to compile g_write.o

Repeat for i_rle.cc in libplotter. Copy ../libplot/i_rle.h to libplotter.
Change declaration of oblock to char oblock[256]. Run above script with
c++ in libplotter to compile i_rle.cc

----------
The problem is with the quantities linebuf and rowbuf. Search for these and
change from unsigned char to char. In fwrite, leave the cast (unsigned char)
alone as this has something to do with data being written. Using above c++
command, compile n_write.cc

-----------
Copy ../libplot/z_write.c z_write.cc. Remember ( see pngconf.h ) that
png_byte means unsigned char. Hence, define data as char * on line 487
and line 61. Run script containing c++ and z_write.o gets built. Now,
build the library libplotter.a in libplotter/.libs using ar:

Part Two.
---------
Using earlier experience, modify the sources in libplot directory and try
using make.

 

Take the above three *.cc files and put them as corresponding *.c files in
libplot directory. Take i_rle.h ( modified ) and put it into the libplot
directory.

 

From Top Directory,

 

make clean
make
