[gdal-dev] Building Gdal with C++ Visual Studio 2019 - Error Linking.

[Carl Godkin]

Hi Peter,

I think you'll have to tell us how you tried to build GDAL in order to get
more help.  There is a lot of variability, but here's how I recently built
both of the versions you mention:

First, I create a file I called "win64.opt" that looks like this:
-----8<--------------------------------------------
WIN64=YES

GDAL_HOME = d:\gdal-3.4.0
BINDIR = $(GDAL_HOME)\bin64
PLUGINDIR = $(BINDIR)\gdalplugins64
LIBDIR = $(GDAL_HOME)\lib64

OPENSSL_PATH=D:\openssl-1.1.1e
SSLLIBS = $(OPENSSL_PATH)/lib/libcrypto.lib $(OPENSSL_PATH)/lib/libssl.lib

CURL_DIR = d:\curl-7.69.1
CURL_INC = -I$(CURL_DIR)\include
CURL_LIB = $(CURL_DIR)\lib\libcurl_imp.lib $(SSLLIBS) wsock32.lib
wldap32.lib winmm.lib

PROJ_INCLUDE = -Id:\proj-8.1.1\include
PROJ_LIBRARY = d:\proj-8.1.1\lib\proj.lib shell32.lib ole32.lib

SQLITE_INC = -Id:\sqlite-3.28.0
SQLITE_LIB = d:\sqlite-3.28.0\sqlite3.lib
-----8<--------------------------------------------
Note that you'll have to build PROJ ahead of time first and adjust the
above depending on where you install it.

Then I build from the VS2019 command prompt with a command line like this
nmake -f makefile.vc EXT_NMAKE_OPT=win64.opt devinstall

If you just want the binaries and don't plan to build against GDAL, you can
use plain "install" instead.

(Note that the PROJ and GDAL worlds are moving to Cmake but the above has
worked for me for many years.)

Hope that helps,
carl
