PDFLib compiled for Cygwin32


Hello everyone,
I have successfully compiled PDFLib for the Cygwin32 environment, and I have been able to build both static and dynamic libraries, and a binding with
C, C++ and PERL (not the one from ActiveState).

For those among PDFLib list readers who do not know Cygwin32 :
it is just an Unix emulation environment on top of any Win32 OS (Win9x, WinNT, ...), that provides POSIX compatibility and makes it possible to
compile most Unix utilities for Win32 with really very few changes. Note that PDFLib comes with appropriate config files to allow it to be compiled
within MSVC only. Now it is possible to use another (free) compiler for Win32 OS with the following patch (see below for instructions).

For those among Cygwin list readers who do not know PDFLib :
It is a library that provides support for producing PDF documents (and graphics) on the fly, without using Adobe's distiller nor TeX/PDF tools suite.
Current version is 2.0, and informations can be found at http://www.ifconnection.de/~tm/. It is possible to link this library with C, C++, Perl,
Python, Tcl, cgi, java, vb. The possibility to link with script languages like Perl, Python, Tcl, ... is made possible with the use of an utility
called SWIG (BTW : this one compiles without any change, but is not required since interface files are already provided).

So, first download 'pdflib-2.0.tar.gz', and apply the following patch (should be 441 lines long), then follow further instructions below  :

Done ? Ok, go to the root directory of PDFLib distribution, then type :
    ./configure
for building a dynamic library called 'pdflib2.0.dll', or :
    ./configure --with-static
for building a static library called 'pdflib.a'.
Note that in the latter case only C and C++ bindings are available.
I have tried the dynamic library with C, C++ and Perl5.00503 compiled with dynamic libraries support.
The compilation for Python or Tcl were skipped since I don't have these.

Do 'make' and wait until everything finishes. Then, cd to 'bind/perl' and do
    perl Makefile.PL ; make ; make install
or
    ./Makefile.PL ; make ; make install
The file called 'Makefile.PL' DOES NOT belong to the original distribution and is installed by the patch above.
This action creates a new Makefile that is better suited for local PERL installation, that is a PERL suite which was compiled locally with dynamic
library support.

You can run the tests afterwards, that is change to the root directory then run 'make test'. In the PERL directory, you can do :
    ./hello.pl
and
    ./pdfclock.pl
Similar programs exists in the C and CPP subfolders (and others too, but I didn't try them).
The first one outputs a PDF document that just contains the typical "Hello World" message, and the second one outputs a PDF document that represents
an analog clock indicating the time when the file was created.

Other tests are available under the 'test' subfolder.

Well, I hope you enjoyed it. Any feedback is of course most welcome, but consider the fact that the current Email address might not be reliable after
the end of this month (july 1999). In the meantime, I just would like other people try this patch to see if it works on their environment too.

Bye,
