Successfully installing JPL!!! by =?iso-8859-1?q?Ellisetty=20Sreedhar?=

Hi,

For those who wanna install JPL, and for those we r struggling
to install JPL, check the following instructions. IF u follow
these instructions, one can easily install JPL. It worked for
me, I hope it will be useful for all.


PERl and JPL Installation instructions and Patches:
---------------------------------------------------
If there is no JPL in the perl5.8.0, which is installed in the
root, please uninstall that perl version
and install the perl5.8.3 version. If there is any old perl
installed, we need to install perl again, because we need to
answer the questions mentioned in step.3,which will be asked
when running 'Configure' command.

1. run 'make distclean'

2.sh Configure -DJPL

3.These are very important, when Configuring answer the
following carefully ...

a. make sure you say 'yes' for perlib.so, since it's not the
default;
b. make sure you say 'no' for using perl5 malloc (default);

4. After Configure -- (maybe not necessary for RedHat but was
for me on Mandrake 9.0): edit
the config.h file and remove the line "#define HAS_CRYPT";

5. run make

6. run make test

if all tests are not successful and if it shows there is an
error in LD_LIBRARY_PATH, then

then you need to set up the shared library path explicitly.
You can do this with

LD_LIBRARY_PATH=`pwd`:$LD_LIBRARY_PATH; export
LD_LIBRARY_PATH

for Bourne-style shells, or

setenv LD_LIBRARY_PATH `pwd`

and run the 'make test' again .

7. run 'make install'

8. after compiling and installing Perl, cd to, say, /usr/bin
(where your
perl executable was installed) and create a soft link this way:

ln -s perl `perl -e "print 'perl'.$]"`

9.
cd to jpl/JNI in your Perl source tree and modify the
Makefile.PL
file

a) and change the following line:

$LIBPATH .= " -R$ENV{JPL_HOME}/lib/$ARCHNAME
-L$ENV{JPL_HOME}/lib/$ARCHN=
AME";

for:

$LIBPATH .=" -L$ENV{JPL_HOME}/lib/$ARCHNAME";

b)

I found a problem in the Makefile.PL in the jpl/JNI directory of
the perl
source tree and this should patch it. The problem was that it
would find
the green_thread directory before native threads on linux.

98c98
< CCFLAGS => "$Config{ccflags} $CCFLAGS -O2",
---
> CCFLAGS => "$Config{ccflags} $CCFLAGS",

< if (/$name$/ and ! /green_threads/ and
!/include-old/) {
< $lib = $File::Find::name;
---
> $pos = $File::Find::name;
> if (/$name$/ && $pos !~ /green_threads/ && $pos !~
/include-old/) {
> $lib = $pos;



10. cd back to the jpl directory , set the JAVA_HOME env
variable


run install-jpl.


11. After JPL is installed cd to the top level JPL directory
you selected when you ran install-jpl.

use the 'setvars' script to generate environment variable
settings for various shells.

.To execute 'setvars', you either need to add the location of
the top-level JPL directory to your path or to
include the full path when invoking 'setvars'.

you can invoke setvars ..

Bourne Shell:
------------
eval `setvars -sh`

or
setvars -sh > .shvars

. .shvars

C Shell:
------

eval `setvars -csh`

or

setvars -csh > .cshvars
source .cshvars


12. Now if everything is ok, then check whether we can run .jpl
files ..
goto perl-5.8.x/JPL/Sample source directory and issue the
following commands to run Sample.jpl file

$ perl Makefile.PL
$ make clean
$ make
$ make install

$ java Sample

if this gives output everything is perfect.. otherwise
something has gone wrong.. check again..!


It worked for me, but I wich you good luck!
