[geos-devel] Re: why this exception happened

[jingping.xie]

Thanks a lot,,strk.

I compiled the veriosn of "[2004/12/16] geos-2.1.1.tar.bz2" with 
VisualStudio.

and it got complie error, so I  made the following change.

$B-!(Bchange the file name of "source\headers\geos\platform.h.vc" to 
"source\headers\geos\platform.h",
"source\headers\geos\version.h.in" to "source\headers\geos\version.h".

$B-"(Bdownload "Stackwalker.h","Stackwalker.cpp" from www.codeproject.com , then 
add them to the folder of "\source\test"

$B-#(Bremove the following files from solution
remove 
"BasicCoordinateList.cpp","CoordinateList.cpp","CoordinateListFactory.cpp","PointCoordinateList.cpp" 
from "Source File\geom\"
remove "CPCLException.cpp","CustomPointCoordinateList.cpp" from "Source 
File\examples\"

$B-$(Badd the following files to solution
add "Profiler.cpp" to "Source Files\util"
add 
"CoordinateSequenceFactory.cpp","DefaultCoordinateSequenceFactory.cpp","DefaultCoordinateSequence.cpp","CoordinateSequence.cpp" 
to "Source Files\geom"

add 
"ElevationMatrix.cpp","ElevationMatrixCell.cpp","ElevationMatrixFilter.cpp" 
to "Source Files\geom\operation\overlay"

that's all
