[gradsusr] error compiling gd library

[Huddleston, John]

Hi Huber,

Did you remove the libpng directory, untar libpng again, configure again with the options specified in Building_GrADS.pdf, and make the system?

Ditto for the GD build.

You must follow the order of the build as shown in the PDF file.

Hello John,

I’ve done your instructions and also I compiled the zlib-1.2.3 library and I have the library libz.a, in supplibs/lib.
And I have the same problem in libpng-1.2-18 compilation.

What is going on with libpng library if I have the libz.a library in the folder supplibs/lib?
(In the end I list the compiled libraries)

Please help me,
Best regards.

Hi Huber, On June 15th I sent you a PDF on how to build GrADS, please look it over,

 libpng doesn't build because you do not have the zlib.

Get zlib from ftp://grads.iges.org/grads/Supplibs/2.0/src/zlib-1.2.3.tar.gz

tar xvfz ./tarfiles/zlib-1.2.3.tar.gz
cd zlib-1.2.3/
./configure --prefix=$HOME/supplibs/src/zlib-1.2.3
make
make install
cp ./lib/libz.a $HOME/supplibs/lib
mkdir $HOME/supplibs/include/zlib
cp ./include/zlib.h $HOME/supplibs/include/zlib

John

John,

Because I found this error when I configure PNG library 1.2:

#cd /home/huber/grads/supplibs/src/libpng-1.2.18
./configure --disable-shared --prefix=/home/huber/grads/supplibs/src/libpng-1.2.18
…
checking for pow in -lm... yes
checking for zlibVersion in -lz... no
configure: error: zlib not installed

I‘ve exported this variable CC=gcc by this other CC='gcc -L/home/huber/grads/supplibs/lib -lz', then I’ve done make, and make install. Provably the libpng12.a library didn’t build well, how I can fix the previous error when I tried to configure the libpng12 library?

Please help me,
Best regards,
Huber Paul Gilt Lopez

Huber

You need the PNG library1.2 not 1.4.  Somehow you've installed a more recent version of PNG into /usr/local

Go back to the PNG 1.2 build and do a "make install" to load it into /usr/local

Otherwise, manually edit the Makefile and change it to point to your $(SUPPLIBS) PNG area.
