Building problems with Microsoft Visual.NET 2003

Reporter: Nuno.Silva@edisoft.pt Date: 2005/12/02 - 15:10
I'm trying to generate the MapServer application using the NMAKE of the MS 
Visual.NET 2003.

I've changed the nmake.opt to be according to my building system and when I 
execute it generates some warnings and errors I'll describe

Here is my nmake.opt:

--- Start of nmake.opt
#
# nmake.opt - MapServer 4.x configuration for MSVC++
#
# This VC++ configuration is used in building MAPSERVER.LIB, MAPSERV.EXE,
# and the other MapServer command-line programs.
#
# To use the makefile:
#  - Open a DOS prompt window
#  - Run the VCVARS32.BAT script to initialize the VC++ environment variables
#  - Start the build with:  nmake /f makefile.vc

# Input raster format options:
#
# The lite version of mapserver 4.x supports only GIF, PNG and JPEG data for 
# input. If you wish to support many geospatial raster formats for input
# you will need the GDAL support library from http://www.gdal.org/.  
# Once built, enable the GDAL flag, and point GDAL_DIR to the directory
# where GDAL was built.

# Input vector format options

# The lite version of Mapserver 4.x only suports ESRI shapefiles for input.
#
# The OGR library (part of GDAL) supports a variety of geospatial vector
# formats including mapinfo, Arc/Info binary coverages, S-57, SDTS, 
# Microstation DGN (pre-v7), TIGER, UK .NTF.  It also include support for
# treating non-spatial tablular data from ODBC, CSV, mysql, Oracle Spatial, 
# and PostgreSQL as spatial table with use of the VRT (virtual) driver.

--- End of nmake.opt

1-In file "maptempalte.c" it generates:
    "maptemplate.c(3093) : warning C4013: 'getpid' undefined; assuming extern 
returning int"
To remove this warning I suggest the following lines
    #if defined(_WIN32) && !defined(__CYGWIN__)
    #   include <process.h>
    #else
    #   include <unistd.h>
    #endif

I've found that Microsoft had included a version of <unistd.h> but I suggest 
the previous code to ensure it generates with MSVC++ 6.0.

2-In file mapgml.c it generates:
    "mapgml.c(831) : warning C4244: '=' : conversion from 'double' to 'int', 
possible loss of data"
    "mapgml.c(835) : warning C4244: '=' : conversion from 'double' to 'int', 
possible loss of data"

Since geometry->occurmin and geometry->occurmax are of type int I 
suggest changing atof() to atoi()

3-In file mapdraw.c it generates:
    mapdraw.c(455) : warning C4013: 'msDrawWMSLayerSWF' undefined; assuming 
extern returning int
    mapdraw.c(462) : warning C4013: 'msDrawWMSLayerPDF' undefined; assuming 
extern returning int

The first warning occurs because in file map.h the declaration 
of msDrawWMSLayerSWF is comment. I suggest moving the #include mapows.h 
from the end of the file to somewhere above the forward declaration of the 
functions in mapswf.c file and uncomment the msDrawWMSLayerSWF with the 
following signature:
#ifdef USE_WMS_LYR 
 MS_DLL_EXPORT int msDrawWMSLayerSWF(int nLayerId, httpRequestObj *pasReqInfo, 
int numRequests, mapObj *map, layerObj *layer, imageObj *image);
 #endif

The second warning occurs for the same reason.
Reading the revision I verified that this function was removed. But I dont 
understand why. I suggest reintroducing this function prototype if 
#include mapows.h was moved has previous stated.

4-In file mapgd.c it generates:
    mapgd.c(1501) : warning C4244: 'function' : conversion from 'double' 
to 'int', possible loss of data
    mapgd.c(1502) : warning C4244: 'function' : conversion from 'double' 
to 'int', possible loss of data
    mapgd.c(1504) : warning C4244: 'function' : conversion from 'double' 
to 'int', possible loss of data

Do explicit cast to int on parameter style->ang to avoid these warnings

The first warning occurs because the zlib include is wrongly enclosed by the 
#if !defined(_WIN32)  #endif
I have the zlib installed on my _WIN32 platform and I wanted to use it. 
Therefore the zlib include shall be enclosed like this:
    #ifdef USE_ZLIB 
    #    include <zlib.h>
    #endif
Also in namke.opt must add the $(ZLIB) to the $(MS_DEFS)

The warnings caused by 'SWFShape' to 'SWFCharacter' occur because the 
SWFButton_addShape signature is void SWFButton_addShape(SWFButton button, 
SWFCharacter character, byte flags); and not
void SWFButton_addShape(SWFButton button, SWFShape shape, byte flags);. Im 
using the Ming 0.3a version.
Seeing through the Mings documentation Ive found that SWFCharacter the 
parent definition for all SWFBitmap, SWFShape, SWFMorph, SWFSound, SWFSprite 
types. For that it shall be necessary to cast any SWFCharacter derived types 
to SWFCharacter in any Mings API functions.

The warnings 'SWFAction' to 'SWFBlock' are similar to 'SWFShape' 
to 'SWFCharacter' warnings, SWFBlock is the parent for SWFAction. It shall be 
necessary to cast any SWFBlock derived types to SWFBlock in any Mings API 
functions. The same applies to 'SWFButton' to 'SWFBlock', 'SWFShape' 
to 'SWFBlock' and 'SWFText' to 'SWFBlock' warnings

    mappdf.c(1350) : warning C4047: '=' : 'int' differs in levels of

The first three warning occurs because the function msSymbolGetDefaultSize 
returns a double and size is int. I suggest to the following line:
    size = MS_NINT( msSymbolGetDefaultSize( &( symbolset->symbol[style-
>symbol] ) ) );

To remove the forth warning, change the line 928 to;
    x = (int) p->x - (int)(.5*PDF_stringwidth(pdf,symbolBuffer,font_id,size)));

To remove the fifth warning, change the line 929 to:
    y = (int)p->y;

The sixth warning is resolved converting the variable phi from float to double 
since the PDF API functions used receive doubles.

The seventh warning can be removed changing the line 1336 to
    size = (int)(label->size*scalefactor);

The last warning occurs because msLookupHashTable function returns char* 
and not int. I suggest changing the code:
    font = msLookupHashTable(&(fontset->fonts), label->font);

    if(!font)
to:
    if( !msLookupHashTable(&(fontset->fonts), label->font) )

These are mostly warnings but it can cause some unpredictable results.
