[postgis-users] Problems building postgis using cygwin

[Yewondwossen Assefa]

Hi There,

I am trying to compile postgis using cygwin but I get some errors with
the dllwrap command . I have followed the NON-UNIX User's guide as well
as some hints that I found in the mailing list archive (specially the
last thread on the same subject between Norman Vine  and Klaus Benndorf
).

 Configuraion :
  - postgresql 7.3.1
 - postgis 0.7.3

 The steps I have done are :

  1) in the postgres root dir
  - apply the patch : postgresql-7.2.3-gcc3.patch to
src/Makefiles/Makefile.win and src/template/win (attached here)
  - add  extern DLLIMPORT double cpu_index_tuple_cost in
src/include/optimizer/cost.h
  - run LDFLAGS=-L/usr/local/lib ./configure --enable-multibyte
--with-CXX --prefix=/usr --sysconfdir=/etc
                           --docdir=/usr/doc/postgresql-$version
  -  make

 2) in postgis

  - make


 The errors that I get are the following :

dlltool --export-all --output-def postgis.def postgis_debug.o
postgis_ops.o post
gis_fn.o postgis_inout.o postgis_proj.o postgis_chip.o

 ....


I have tried to modify the dllwrap command execution by adding manually
-L../../src/backend -lpostgres  but It did not change anything.

Any hints would be appreciated.


Thanks,
