is there something i forgot ?

Hello Domenico,
please test *.hbp files committed with r2995
on your BSD system and give feedback.
Macro "{linux}" not for BSD:
The macro for unix has also effect on LINUX, so
i changed it to:
"{unix}"

If there are many other places need to modify the macro,
please send a list of them for check and commit.

With regards,

Hi Wilfried, some minutes ago i update hwgui to last commit ( 2996 )

build libs with normal warnings

try to rebuild tutor with

hbmk2 tutor.hbp

received this warning

Error: Referenced, missing, but unknown function(s): HWG_SIN(),
HWG_COS()

no tutor created

same errors with dbchw

Hello Domenico,
please check, if the missing symbols are in the HWGUI lib:
cltest@afulinux4:~/hwgui/lib$ nm libhwgui.a | grep HWG_COS
0000000000000490 T HB_FUN_HWG_COS
cltest@afulinux4:~/hwgui/lib$ nm libhwgui.a | grep HWG_SIN
0000000000000470 T HB_FUN_HWG_SIN

If not:
it seems, that the math library "libm.a" or "libm.so" was not
included by the the HWGUI build:
Harbour 3.2.0dev (r2104281802)
Copyright (c) 1999-2021, https://harbour.github.io/
ld: error: undefined symbol: sin

but i don't know why not. I checked all files of the HWGUI build process:

1. the functions HWG_COS() and HWG_SIN() are implemented
   in source code file misc.c for WinAPI and GTK.
   This functions call the basic functions "sin" and "cos" of libm.xx of the
   GCC and returned their value in Harbour notification.

2. the file "hwgui.hbm" contains a list of all source file to compile:
   {unix}source/gtk/misc.c
   ...
   {win}source/winapi/misc.c

3. The link option "-lm" is necessary to include the libm library.

Instead of using the hbmk2 utility, you can use as alternative method
the following:

1. Edit the .profile of userid running hwgui, as
   described in install.txt . After a new login the entries are valid.

2.Edit the script make_gtk.sh and modify the
installation path of Harbour to your own needs:
export HB_ROOT=$HOME/Harbour/core-master

1. Be shure, that the script have execute permission, otherwise say:
   chmod 755 make_gtk.sh

2. Remove all files .a in directory lib and all .o in obj, if existing

3. Try to build hwgui with
   ./make_gtk.sh -hb
   Calls the system make utility with "source/gtk/Makefile.linux"

4. Now try to build tutor and dbch with hbmk2 ...

Please give feedback, if you have success, otherwise
collect all outputs into one text file and post them for analyis.
