(sorry if its the second and same mail you've received...)<br>
<br>
Hi arjen (and you all plplot-general if this mail succeeds in reaching
you...)!<br>
<br>
well, I can now be more precised on the issus I encountered for porting
PDL::Graphics::PLplot<br>
on cygwin.<br>
<br>
Here is my environment:<br>
<br>
windaube XP [french joke, like winstinks XP ; ) ] 5.1 build 2600
service pack2<br>
<br>
cygwin dll 1.5.18 / shared id cygwin 1S4<br>
<br>
perl v5.8.7 build for cygwin<br>
<br>
PDL 2.4.2<br>
<br>
plplot5.5.3<br>
<br>
So, there are strange things during the install of PDL:<br>
- at perl Makefile.PL<br>
it can't find libplplot.dll : actually, libplplot.dll.a
exists so, it finally works if<br>
- I
"cp libplplot.dll.a libplplot.dll <br>
or - I
modify Makefile.PL in /Graphics/PLplot : my $libname =
"libplplotd.dll.a" instead of<br>
my
$libname = "libplplotd.dll".config("so") <br>
- finally, it (seems to) work but, at the end of "make":<br>
it can't find /blib/script/pdl : actually, "pdl.exe"
exists, so I "cp PDL.exe PDL" ... and it works (?)<br>
<br>
- make install : all (seems to be) is ok<br>
<br>
- perldl inline command works:<br>
perldl> $x = sequence 3,4<br>
perldl> set $x, 2,1,99<br>
perldl> p $x<br>
[<br>
[ 0 1 2]<br>
[ 3 4 99]<br>

href="http://www.us025.ird.fr/article.php3?id_article=17">http://www.us025.ird.fr/article.php3?id_article=17</a>)<br>
<br>
Now, the problem is:<br>
perl -v "use PDL::Graphics::PLplot;"<br>
can't load
'/usr/lib/perl5/site_perl/5.8/cygwin/auto/PDL/Graphics/PLplot/PLplot.dll'

<br>
But
/usr/lib/perl5/site_perl/5.8/cygwin/auto/PDL/Graphics/PLplot/PLplot.dll
exists (libPLplot.dll.a too) and is non void!!!<br>
<br>
I didn't find any similar situation neither on the web nor in forums
and i can't remember the number of (re)installation of <br>
the whole config (including cygwin) : (<br>
<br>
any suggestions will be welcomed as the first day of spring after a
long and cold winter : p,<br>

Hm, I get similar files (libplplot.dll.a etc.) when using the builds
for Fortran and C. But somehow the GCC linker I use then is able
to use that exact file.
I think that the Perl Makefile script is not aware of this
convention under Cygwin. Have you asked this on the Perl newsgroup?

Here again, a similar mismatch in expectations.
As I know nothing about the Perl make system, I can not help out
with these issues.

My guess is that the dynamic loader is expecting a file with a
different name or extension. Could you copy the .dll file to:
PLplot.so and PLplot.dll.so ?
Just a few suggestions, as I am not at all familiar with this
part of Perl.

Arjen

It works!<br>
<br>
long:<br>
Hi all,<br>
<br>
First, thanks to all who send me advices and encouragements: Alan,
Arjen and Kare...<br>
<br>
Actually, I've forgot the SECOND RULE: "don't forgot the FIRST RULE :
check your PATH!!" :-(<br>
(Kare-from-Norway was right!)<br>
That was not a big issue! When I had configure/make/make install
plplot5.5.3 and perl/make/make install PDL2.4.2<br>
with the definition of the PATH<br>
<br>
</font><font color="#000000"><tt>PATH: /usr/X11R6/bin<br>
PATH: /usr/X11R6/lib<br>
PATH: /usr/local/plplot/lib/plplot5.5.3/driversd<br>
PATH: /usr/local/lib<br>
PATH: /usr/local/lib/pkgconfig<br>
PATH: /usr/local/plplot/bin<br>
PATH: /usr/local/plplot/include/plplot<br>
PATH: /usr/local/plplot/lib<br>
PATH: /usr/local/bin<br>
PATH: /usr/bin<br>
PATH: /usr/include<br>
PATH: /lib<br>
PATH: /bin</tt></font><font color="#000000"><br>
<br>
Along my many tests, sometimes i change the path but when i exit from
cygwin, my definitions were losts.<br>
It finally works when I've remembered to define PATH directly in
/etc/profile.<br>
<br>
perl succeeds in loading the dll and i can execute the c- and
perl-examples lying in plplot/share/plplot5.5.3/examples !<br>
Below this message, I give the precise details of my installation.<br>
<br>
Now, my next goal is to succeed in writing png files...once again, if
someone has suggestions...<br>
<br>
I've installed the gd-2.0.33 library, so plplot installs the gd driver
and enables<br>
png files. Here is the the Configure results of plplot:<br>
<br>

This should contain all the information necessary for loading the driver (via libtool) Regards, Arjen |

On top of that it turns our you are the first to attempt to use the (default) dynamic devices on the Cygwin platform. I note that Arjen has already responded to you with possible ways to debug that option, but I encourage Arjen as a PLplot developer to continue with that effort on his own Cygwin platform since it should be much quicker for him to debug that locally on his own computer rather than attempting remote debugging through you. Once he finds a solution, I am sure he would let you know what it is so you can use it as well. Until Arjen debugs the dynamic device case for Cygwin, there is an alternative for you which is documented in the Cygwin advice in the INSTALL file. Simply use the --disable-dyndrivers ./configure option. For that case, the device drivers are not dynamically loaded and are instead put directly into the PLplot library which is automatically loaded at the start of run time. I understand that Arjen has already tested the --disable-dyndrivers option on Cygwin, and it works fine even for the gd device driver. Note, that the non-dynamic drivers do have the drawback that they are all loaded simultaneously with the library which increases the memory footprint of PLplot compared to the dynamic drivers case where only one user-requeste= d device driver is dynamically loaded. So you will want to switch back to th= e (default) dynamic device driver case as soon as Arjen debugs that case on Cygwin. Finally, Bruno, thanks very much for your patience and help with PLplot on Cygwin. It is a fairly new platform for us where, for example, we have just discovered how to get shared libraries to work. Thus, there is still some stuff (such as dynamic device drivers) to get working on Cygwin that alread= y work fine on the other PLplot platforms. Alan __________________________ Alan W.

He misjudged the outcome of the configure/build process. Of course I forgot about the dynamic devices issue ... Anyway we definitely are making progress. Regards, Arjen |
