(PL/Perl is a plugin to the Postgres Database which allows one to create functions within the RDBMS written in Perl) Here are the specs: Windows NT Workstation, 4.0 (S.P. 6a) Cygwin DLL v. 1.1.4(0.2632) Postgres 7.02 Perl 5.6.0 CygIPC 1.07-1 I followed the instructions for installing Postgres at this url: http://people.freebsd.org/~kevlo/postgres/portNT.html And I used the binary perl distribution from here: http://cygutils.netpedia.net/V1.1/perl-5.6.0/index.html (When trying to configure the sources i get an "Invalid DLL Entrypoint" popup error msg from "fred.exe," to wit: "The dynamic link library C:\cygwin\tmp\perl-5.6.0\UU\dyna.dll is not written correctly. The stack pointer has been left in an inconsistent state. The entrypoint should be declared as WINAPI or STDCALL. Select YES to fail the DLL load. Select NO to continue execution. Selecting NO may cause the application to operate incorrectly." When I answer NO to the dialog, I get a response from the Configure program that "Perhaps you should not use dynamic loading.", which evidently is necessary for PL/Perl.) I created symlinks to the perl dll: $ cd /usr/local/lib/perl5/5.6.0/cygwin/CORE $ ln -s libperl5_6_0.dll libperl.dll (... ditto for libperl.a and libperl.def...) $ cd /usr/local/bin $ ln -s libperl5_6_0.dll libperl.dll Anyway, when I goto $POSTGRES_SRC/src/pl/plperl and run $ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/perl5/5.6.0/cygwin/CORE:/usr/local/bin \ perl Makefile.PL POLLUTE=1 $ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/perl5/5.6.0/cygwin/CORE:/usr/local/bin \ make I get the messages appended at the end of the email. I'm having trouble deciphering these messages and determining whether this is a "Cygwin" issue or a "PLPerl" issue. My questions: * Is this a problem with cygwin's ld2 or dllwrap? or is it a problem where the perl distro i am using didn't have an "export definition file" with it? or ??? * What can I do to fix it :) Thanks!!! ed $ LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/usr/local/lib/perl5/5.6.0/cygwin/CORE:/usr/local/bin make mkdir blib mkdir blib/lib mkdir blib/arch mkdir blib/arch/auto mkdir blib/arch/auto/plperl mkdir blib/lib/auto mkdir blib/lib/auto/plperl gcc -c -I../../../src/include -I../../../src/backend -I/usr/local/include -fno-strict-aliasing -I/us r/local/include -DPERL_POLLUTE -DUSEIMPORTLIB -O -DVERSION=\"0.10\" -DXS_VERSION=\"0.10\" -I/u sr/local/lib/perl5/5.6.0/cygwin/CORE plperl.c In file included from plperl.c:76: /usr/local/lib/perl5/5.6.0/cygwin/CORE/perl.h:2027: warning: `DEBUG' redefined ../../../src/include/utils/elog.h:22: warning: this is the location of the previous definition gcc -c -I../../../src/include -I../../../src/backend -I/usr/local/include -fno-strict-aliasing -I/us r/local/include -DPERL_POLLUTE -DUSEIMPORTLIB -O -DVERSION=\"0.10\" -DXS_VERSION=\"0.10\" -I/u sr/local/lib/perl5/5.6.0/cygwin/CORE eloglvl.c /usr/local/bin/perl -I/usr/local/lib/perl5/5.6.0/cygwin -I/usr/local/lib/perl5/5.6.0 /usr/local/lib/ perl5/5.6.0/ExtUtils/xsubpp -typemap /usr/local/lib/perl5/5.6.0/ExtUtils/typemap SPI.xs > SPI.xsc & & mv SPI.xsc SPI.c gcc -c -I../../../src/include -I../../../src/backend -I/usr/local/include -fno-strict-aliasing -I/us r/local/include -DPERL_POLLUTE -DUSEIMPORTLIB -O -DVERSION=\"0.10\" -DXS_VERSION=\"0.10\" -I/u sr/local/lib/perl5/5.6.0/cygwin/CORE SPI.c In file included from SPI.xs:41: /usr/local/lib/perl5/5.6.0/cygwin/CORE/perl.h:2027: warning: `DEBUG' redefined ../../../src/include/utils/elog.h:22: warning: this is the location of the previous definition Running Mkbootstrap for plperl () chmod 644 plperl.bs LD_RUN_PATH="" ld2 -o blib/arch/auto/plperl/plperl.dll -L/usr/local/lib plperl.o eloglvl.o SPI.o /u sr/local/lib/perl5/5.6.0/cygwin/auto/Opcode/Opcode.dll -L/usr/local/lib/perl5/5.6.0/cygwin/CORE -lpe rl /usr/local/lib/perl5/5.6.0/cygwin/CORE/libperl5_6_0.a dllwrap --dllname plperl.dll --driver-name gcc --dlltool dlltool --export-all-symbols --as as --outp ut-def libplperl.def --output-lib libplperl.a \ -L/usr/local/lib plperl.o eloglvl.o SPI.o /usr/local/lib/perl5/5.6.0/cygwin/auto/Opcode/Opcode.dll -L/usr/local/lib/perl5/5.6.0/cygwin/CORE -lperl /usr/local/lib/perl5/5.6.0/cygwin/CORE/libperl5_6_0. a dllwrap: no export definition file provided dllwrap: creating one, but that may not be what you want /usr/bin/ld: warning: cannot find entry symbol __cygwin_dll_entry AT 12; defaulting to 62881000 plperl.o(.text+0x1d4):plperl.c: undefined reference to `elog' . .
