Troubles making a 64 bit app.

[flicker177]

Hello all,

I have an old clipper app that I have ported to Harbour 32 bit and it works well. Just for the heck of it I thought I would try to compile it as a 64 bit app. I have installed the latest 64 bit Harbour and the 64 bit MinGW compiler from the Whosaway site. It won't compile, I get a GCC error. After a couple of days trying everything I could think of, I'm stuck.

To simplify the troubleshooting I tried to compile "hello.prg" the same way and I get the same error.


Here is my Harbour build:
D:\Sail-2020-64\Pgms>harbour -build

Harbour 3.2.0dev (r2003271400)

Here is my MinGW build:
D:\Sail-2020-64\Pgms>gcc --version

I have set the environment variable HB_ARCH:

D:\Sail-2020-64>set HB_ARCH
HB_ARCH=64


Here is the result of trying to compile "hello.prg"
D:\Sail-2020-64\Pgms>hbmk2 -comp=mingw64 hello.prg

Harbour 3.2.0dev (r2003271400)

To test the gcc compiler I compiled the usual "hello.c" (not the harbour output)
D:\Sail-2020-64\Pgms>gcc hello.c -ohello.exe

That compiles and runs fine:

D:\Sail-2020-64\Pgms>hello
Hello, World!


So...I'm most confused! The Harbour compiler seems to run fine, the gcc compiler runs fine on its own. I'm pretty good with Clipper code, not so much with the workings of C compilers. Can anyone help? I'd be most grateful for some insight.

Thanks!

Hi Bill:

   Here is *my* build batch file for 64-bit apps. It relies on there being a MinGW 64-bit Compiler (mine is MinGW 9.3.0)

   and a 64-bit Harbour folder (Mine is c:\HB3264)

   I have created several 64-bit MinGW apps successfully with this build batch file.

Wow!! That works! I had to change the paths a bit to match mine and add an hbp and rsp file but that was easy and all is fine. Now I can study what's different from what I was doing before; that should be easy and educational. This is a great group!

Thanks so much for the instant response and help.

Hi Bill:

   Glad you found the batch file useful.

   However, I'm just learning Harbour and MinGW, so I'm changing the bldapp64.bat file and trying new things out -- as I learn more.

   Also, I use an .HBP file and place some options in it -- which I don't understand very well, so I change that file also.

   I wish I knew more -- but every day is a learning experience.

   I do note, though, that my 64-bit apps seem a lot bigger than my prior 32-bit apps. And I don't know why.

   I also note that moving some options from the .hbp file to the command line in the batch file seems to work better. And I don't know why either.

   Anyway, please don't use me as a 'fountain of information'.  I definitely am not !  I'm just a beginner.
