Re: configure PostgreSQL with PERL: Perl version 5.8 or later is required, but this is .

I corrected 'PERL=' to include the executable.
I tried again.

./configure PERL=/c/EnterpriseDB/LanguagePack/9.5/x64/Perl-5.20/bin/perl5.20.3.exe --with-perl --with-includes=/c/EnterpriseDB/LanguagePack/9.5/x64/Perl-5.20/lib/CORE:/c/Users/AnonymousUser/Documents/zlib-1.2.8-win32-x86_64/include --with-libraries=/c/EnterpriseDB/LanguagePack/9.5/x64/Perl-5.20/bin:/c/EnterpriseDB/LanguagePack/9.5/x64/Perl-5.20/lib/CORE:/c/Users/AnonymousUser/Documents/zlib-1.2.8-win32-x86_64/bin:/c/Users/AnonymousUser/Documents/zlib-1.2.8-win32-x86_64/lib --host=x86_64-w64-mingw32 --prefix=/usr/local/pgsql_0ab9c56_debug --disable-rpath --enable-depend --enable-cassert --enable-debug --with-extra-version=_CFLAGS_O_0ab9c56 CFLAGS="-O -fno-omit-frame-pointer" 2>&1 | tee configure_OPTIONS_EnterpriseDB_PERL_without_SUBDIR_sys.txt

Relevant output is the following.

I try to 'make'

make 2>&1 | tee make_ALONE_OPTIONS_EnterpriseDB_PERL_without_SUBDIR_sys.txt

But now within the 'make', I am getting complaints
saying "warning: win32_FUNCTION redefined."

These complaints go on and on, but they are all similar.
They seem to be complaints about networking functions begin re-defined

win32_*
E.g. win32_connect

These function headers are found in the python subdirectory and files.

CORE/sys/socket.h
CORE/netdb.h

They were most like likely included by using the

./configure line --with-includes option

--with-includes=/c/EnterpriseDB/LanguagePack/9.5/x64/Perl-5.20/lib/CORE

Note, perl.h lives in lib/CORE, so I am not sure about removing that option.

Eventually, these complaints lead to . . .

Tom,

I m getting this.

TargetUser(at)TARGETMACH ~
$ perl -v
This is perl, v5.8.8 built for msys-64int

5.8.8 is not right. See later emails.

It's trying to extract the Perl version number from the output of
"perl -v", and evidently failing to find one. What does "perl -v"
print with that version of Perl?
