[Gdal-dev] Building GDAL by MinGW

[Hisaji Ono]

Hi, Mr. Vine.

I can't still build GDAL by MinGW.

I tried to build latest gdal-cvs-030825 using following option under , as
you said, "separate" MinGW building environment. And gcc version number is
3.2.3.

./configure --prefix=$MINGW --host=i686-pc-mingw32 --with-libz=internal --w
ith-png=internal --with-libtiff=internal --with-geotiff=internal --without-
jpeg --without-python --without-pg

However I've got following error messages.

cplgetsymbol.cpp: In function `void* CPLGetSymbol(const char*, const
char*)':
cplgetsymbol.cpp:174: invalid conversion from `int (*)()' to `void*'
make[1]: *** [cplgetsymbol.o] Error 1
make[1]: Leaving directory `/home/Administrator/gdal-cvs-030825/port'
make: *** [port-target] Error 2

Could you give me any suggestion to deal with this error and go forward.

Regards.

Hisaji,

Assuming line 174 reads:
pSymbol = GetProcAddress( (HINSTANCE) pLibrary, pszSymbolName );

Try changing it to:
pSymbol = (void*) GetProcAddress( (HINSTANCE) pLibrary, pszSymbolName );

If this fixes the issue let me know and I will correct the master. The
code in this win32 implementation was written for VC++ and this may be the
first time it has been used with another compiler.

Best regards,

[Hisaji Ono]

Thank you very much, Mr. Warmerdam.

I could build this code. However I've still got following errors. Below
header files do exist.

I've modified GNUMakefile as follows and could build GDAL at last. MinGW's
gcc seems not to like specifying fullpaths.

#INCLUDE = $(GDAL_INCLUDE) -I$(GDAL_ROOT)/frmts -I$(GDAL_ROOT)/alg
INCLUDE = -I../port -I../gcore -I../ogr -I../frmts -I../alg
-------------------------------------------------------------
CONFIG_LIBS = -L../ -lgdal.1.1 -lm -lm

Thanks.

This works

I had made this change in my MingW32 code but hadn't submitted a change
