Harbour and Unix

[Ani Garza T]

Hi, 

I've been a Clipper programer since 1986, and I like it very much. All my programs worked great until Windows 64 bit arrived. 
So I am compiling my clipper programs with Harbour and they are working great in windows 32 and 64 bits.

I use the HBMK2 to compile my project. 

I just have one question because I need to run a program in UNIX.

How do I need to compile it in order to run on UNIX?  Can I simply install the same files I install on DOS?  Will the file.exe  generated when I compiled with HBMK2 run on UNIX?  May I compile under DOS for a UNIX version?  I need to compile in my computer and be able to install in a UNIX server.

Does the same HBMK2 version to compile will work for UNIX?

Any help is really appreciated, thanks,  -Ani Garza T

Hi Ani.
I did something like this last week.
You need Linux to build a Linux executable, but you can do this using a Virtual Machine in Windows.
There are other solutions but what I did :
- Download VmWare Player here

https://my.vmware.com/web/vmware/free#desktop_end_user_computing/vmware_player/7_0

- Download Ubuntu 14.04.2 image for VmWare here

http://www.osboxes.org/ubuntu/

- Run the Ubuntu VM image and configure as you need/like...

- Install git

sudo apt-get install git

- Download Harbour source code ( I use Viktor's fork...  https://github.com/vszakats/harbour-core READ !!! )

git clone https://github.com/vszakats/harbour-core.git harbour-core

- Generate Harbour binaries and install

cd harbour-core
make
sudo make install

- Test Hello World !

cd tests
hbmk2 hello.prg
./hello

Harbour should be Ok now.
 
Beyond other things, you very probably will face some issues with capitalization and paths, as they are different in Windows and Linux worlds... #ifdef / #endif is a good friend when different code is needed in different platforms !
Share your source code via SAMBA ( or copy it to the Linux VM, but sharing you can use the Windows text editor you are comfortable with ) and go Harbour !
 
If you need any help please ask.

Hi Mauricio,

Thanks for your response, I'll go over the information you sent.

Do I need another version of Harbour, or may I use the same version I use for DOS?  Can I use the same HBMK2 and use the same myfile.hbp.

I create the Harbour exe like this:

c:\hbmk2  myfile.hbp

myfile.hbp file contains the following:

-omyprogram
-w0
-es2
-rebuild
-ldflag=-Wl,--allow-multiple-definition

mainprogram

___________
I really don´t understand the parameters, but my programs get compiled and linked with this .hpb generating an exe and working great!!  I am really surprised how well Harbour works with my old Clipper programs. Now I need to generate the .exe or .bin so that it runs on UNIX.

Thanks for your help!!  -Ana

Hi Ani.
 
Seems you know almost nothing about UNIXes, you will need to learn a bit before proceed...
Don't worry UNIXes are not my day to day too but with some basic commands it's possible I play a little.
At first, there isn't "an" UNIX, there are UNIX "flavors" and, although they are very similar, there are differences.
I talked about a flavor called Linux which is the most used nowadays, and even Linux has hundreds of different "flavors" !
My suggestion was Ubuntu Linux because it seems to be the most Linux flavor used.
Do you know which UNIX flavor are you targeting ?

You use the .hbp in the same way in Windows and UNIXes, there is no problem here.
--allow-multiple-definition is not recommended.
