I thought this would be simple. (I keep making that mistake ;-) )

I have a Harbour app that I started working on 30 years ago in Clipper S’87. It has always run under Windows. In the current version I’m compiling it with Harbour 3.2-dev and using the GT system to provide a realizable window and this works fine. At the start of the program I have this GT setup:

ANNOUNCE HB_GT_SYS

REQUEST HB_GT_WVT_DEFAULT

// get font size and width from system file

SELECT 1

USE SAILSYS

GO TOP

hb_gtInfo( HB_GTI_FONTSIZE, FONT_SIZE )

hb_gtInfo( HB_GTI_FONTWIDTH, FONT_WIDTH )

hb_gtInfo( HB_GTI_WINTITLE, "Flickerware" )

hb_gtInfo( HB_GTI_ICONFILE, "Flickerware45.ico" )

hb_gtInfo( HB_GTI_FONTNAME, "Consolas" )

hb_gtInfo( HB_GTI_SELECTCOPY, .T. )

hb_gtInfo( HB_GTI_CLOSABLE, .T. )

hb_gtInfo( HB_GTI_RESIZABLE, .T. )

hb_gtInfo( HB_GTI_CODEPAGE, 255 )

hb_gtInfo( HB_GTI_ALTENTER, .T. )

SetMode( 25, 80 )

I compile the program using hbmk2 like this:

hbmk2 sail.prg hbwin.hbc -comp=mingw

This works fine and gives me a readable and resizable window.

Now I’m trying to port the app to Linux. I have it running fine in the terminal. However all my attempts to use the GT system in Linux have issues.

My Linux GT setup is this:

ANNOUNCE HB_GT_SYS

REQUEST HB_GT_XWC_DEFAULT

// get font size and width from system file

SELECT 1

USE SAILSYS

GO TOP

hb_gtInfo( HB_GTI_FONTSIZE, FONT_SIZE )

hb_gtInfo( HB_GTI_FONTWIDTH, FONT_WIDTH )

hb_gtInfo( HB_GTI_WINTITLE, "Flickerware" )

hb_gtInfo( HB_GTI_ICONFILE, "Flickerware45.ico" )

hb_gtInfo( HB_GTI_FONTNAME, "Monospace Regular" )

hb_gtInfo( HB_GTI_SELECTCOPY, .T. )

hb_gtInfo( HB_GTI_CLOSABLE, .T. )

hb_gtInfo( HB_GTI_RESIZABLE, .T. )

hb_gtInfo( HB_GTI_CODEPAGE, 255 )

hb_gtInfo( HB_GTI_ALTENTER, .T. )

SetMode( 25, 80 )

If I compile the app like this:

hbmk2 sail.prg

I get this:

Harbour 3.2.0dev (r2512120309)

Compiling 'sail.prg'...

Compiling 'SAILPRC.prg'...

Compiling 'SAILAWD.prg'...

Compiling 'SAILSER.prg'...

collect2: error: ld returned 1 exit status

I looked all over the place and could not find any HB_FUN_xxxx files, maybe these are internal functions?

I then tried compiling like this:

hbmk2 -gtxwc sail.prg

This eliminates the compile error and I can actually run my program. It comes up in a very small X11 window. If I resize the window my program doesn’t resize with it, if I make the window even smaller line wraps cause fragmenting of the display. Also my hb_gtInfo options seem to be ignored.

I’m sure I’m showing my ignorance here, I know xBase better than Linux/Unix. I hope what I’m trying to do is understandable. Thanks in advance for any help.
