[geos-devel] Problems compiling nightly snapshot

[Paul Meems]

Mateusz,

Our problem is that when we want to use the GEOS library in our own code we
need to include geos_c.h
That is logic. We do that as well with other libraries we use, like gdal,
proj, etc.
For that reason in the build script we copy the needed header files to a
include folder higher in the tree after compiling. So our application knows
it should look in that folder and everything works.

This approach works well. When we update the source code of such a library
and we compile it again the header files are neatly copied.
But this doesn't work with geos_c.h because it refers to two files in sub
folders. We can do two things: either create the sub folder and copy the two
files in to it or copy geos_c.h and open it and change geos/version.h to
geos_version.h and geos/export,h to geos_export,h..
Currently we do the latter workaround.

As I understand now the situation for GEOS cannot be changed. So we need to
re-thing our workaround.

Thanks for the explanation.
