OK, thanks. Next question --- are the installed file locations the same
for a MinGW install and a pginstaller install? I don't think
pginstaller does a MinGW install because it doesn't have the build
environment in the tarball.
However, the big difference seems to be that Magnus has -Llib and -Lbin,
while you have only the -Lbin. I have MinGW and pginstaller installed
here. How can I set things up to test this?
Now looking at the Makefile.global in the 8.1.2 pginstaller install, in
Makefile.global, $libdir is set in a pgxs-specific block:
libdir := $(shell pg_config --libdir)
and that seems to work:
C:\Program Files\PostgreSQL\8.1\bin>pg_config --libdir
C:/PROGRA~1/POSTGR~1/8.1/lib
and that is set to LDFLAGS, which is later propogated to SHLIB_LINK,
though SHLIB_LINK moves all the -L flags to the front, so what you see
on the link line is not the ordering used to create the value.
Andrew, can you try echoing $libdir and $SHLIB_LINK in the Makefile to
find those values?
here is a test case log (including a test makefile). I ran the tests as
you can see with both installer 8.1 and mingw installed CVS tip, with
the same results.
cheers
