[Bioperl-l] Module issue with cygwin-perl vs. Activestate Perl

[Mark A. Jensen]

Jonathan-

I have an utter kludge for this very problem, if I
understand it correctly. The kludge works for
me a majority of the time. Be warned that this
is in no way optimized or clever; there is no warranty
expressed or implied...

Two scripts are below; one runs the other. Together
they convert a makefile generated by ActiveState 
into one suitable for a cygwin make. When the 
cygwin make is run after conversion, the installation
occurs in the ActiveState locations. A demo session
follows (note that 'asperl' is an alias, defined as

 alias asperl=/cygdrive/c/Perl/bin/perl

)
cygwin session:

 $ wget http://search.cpan.org/CPAN/authors/id/N/NI/NI-S/Devel-Leak-0.03.tar.gz
 $ tar -xzf Devel-Leak-0.03.tar.gz
 $ cd Devel-Leak-0.03
 $ asperl Makefile.PL
 $ as2cyg.sh
 $ make
 $ make test
 $ make install

This is how I constantly install CPAN modules "by hand" 
into my ActiveState instance. I really hope this helps. 
The scripts are below.

cheers and good luck-
Mark

cygwin paths...note these are both in $PATH
/usr/local/bin/as2cyg.sh :

 #!/usr/bin/bash
 TF=$(uuidgen)
 conv-ASmake.sh Makefile > $TF
 mv $TF Makefile
 #end of as2cyg.sh

/usr/local/bin/conv-ASMake.sh : (note this is a sed script)

#!/usr/bin/sed -f
#converting an ActiveState PERL Makefile to run under cygwin make:
s/^DIRFILESEP = ^\\/DIRFILESEP = \//
s/^NOOP = rem/NOOP = :/
# -or- NOOP = echo -n

s/C:/\/cygdrive\/c/
# sed to convert directory \ to /
s/\([\)0-9a-zA-Z.]\)\\\([\(0-9a-zA-Z]\)/\1\/\2/g

# a key conversion for DOC_INSTALL action
/^DESTINSTALLVENDORHTMLDIR/ a\
DECYGDESTINSTALLARCHLIB = $(subst /cygdrive/c,c:,$(DESTINSTALLARCHLIB))
