Compiling a PM sample with GCC (2023)
« on: April 22, 2023, 03:40:46 am »
Hi

I had setup a new Dev ArcaOS 5.0.7 VM to keep going with the "fun" of trying to compile some old Presentation Manager samples with GCC and other open source tools.

This is my Vanilla ArcaOS VM with:
- yum install git gcc make libc-devel binutils watcom-wrc watcom-wlink-hll

And I made sure that I have on the config.sys
 SET INCLUDE=C:\usr\include
 SET EMXOMFLD_LINKER=wl.exe
 SET EMXOMFLD_TYPE=WLINK
 
I'm very happy that the samples we checked before are now compiling and working.
- https://github.com/OS2World/DEV-SAMPLES-PM-PMWalker2
- https://github.com/OS2World/DEV-SAMPLES-PM-BitCat
- https://github.com/OS2World/DEV-SAMPLES-PM-PMHello

My new compile attempts, questions and cry for help come next.

Regards

Hi

Now, I'm trying to compile VectFont
https://github.com/OS2World/DEV-SAMPLES-PM-VectFont

But checking the included makefile (VECTFONT) against the makefile I did, I'm not sure if missing some source code here.

I'm attaching my build attempt and the errors on make.out. I don't care about the warnings yet, just the errors to try to compile the sample as it is includes first and later go after the warnings.

Regards

Missing code? Look at VECTFONT and VECTFONT.LNK, seems there are various vf**.c files expected.

Martin, I seem to remember that the Petzold book builds one example upon the other. As Dave said, you will need to find the missing source files on the floppy disk (?) and add them to the GitHub repo.

Hi

I found the full version:
https://archive.org/download/OS2BBS/08-Other.zip/S12219.ZIP

Now I have to check out how to recreate the makefile with all those.

Hi

Checking my makefile I think I need to call all the .obj to create vectfont.exe.

I changed to this:
Quote
vectfont.exe : vectfont.obj vectfont.res vf00.obj vf01.obj vf02.obj vf03.obj vf04.obj vf05.obj vf06.obj vf07.obj vf08.obj vf09.obj vf10.obj vf11.obj vf12.obj vf13.obj vf14.obj vf15.obj vectfont.def
   gcc -Zomf vectfont.obj vf00.obj vf01.obj vf02.obj vf03.obj vf04.obj vf05.obj vf06.obj vf07.obj vf08.obj vf09.obj vf10.obj vf11.obj vf12.obj vf13.obj vf14.obj vf15.obj vectfont.def -o vectfont.exe
   wrc vectfont.res

Now the error changed to:

Code: [Select]
gcc -Zomf vectfont.obj vf00.obj vf01.obj vf02.obj vf03.obj vf04.obj vf05.obj vf06.obj vf07.obj vf08.obj vf09.obj vf10.obj vf11.obj vf12.obj vf13.obj vf14.obj vf15.obj vectfont.def -o vectfont.exe

os2tk45\h\libc\stdlib.h has,
Code: [Select]
#define max(a,b) (((a) > (b)) ? (a) : (b))
#define min(a,b) (((a) < (b)) ? (a) : (b))

Hi  Dave

I haven't installed the OS2tk45.

I'm using this one:
Quote
[C:\usr\include]dir stdlib.h

The volume label in drive C is ARCAOS.
The Volume Serial Number is C470:B5BB.
Directory of C:\usr\include

 4-22-23  7:24a        16,886    124 a---  stdlib.h
        1 file(s)      16,886 bytes used

It does not has any max(a,b) or min(a,b). If I include those lines on stdlib.h I get the same error.

Code: [Select]
gcc -I. -Zomf vectfont.obj vf00.obj vf01.obj vf02.obj vf03.obj vf04.obj vf05.obj

Now, I installed os2tk45, but I can not find stdlib.h to compare it with the one on "C:\usr\include".
Which package contains the os2tk45 stdlib.h ?

Regards

I found libc/stddef.h in os2tk45, the complete package. I guess Bitwise didn't add the conflicting libc to the rpm.
Simplest in this case is just to add the defines, with guards incase someone does use the toolkit or such where min and max are defined. VECTFONT.H seems like a good candidate, could create a header as well.
Code: [Select]
diff --git a/VECTFONT.H b/VECTFONT.H
index fcae64a..6fac9ca 100644
--- a/VECTFONT.H
+++ b/VECTFONT.H
@@ -48,3 +48,10 @@ VOID Display_Fade (HPS hps, LONG cxClient, LONG cyClient) ;

 VOID Display_Spokes (HPS hps, LONG cxClient, LONG cyClient) ;    // VF13

+#endif

This compiles but doesn't work as expected. Wrong max and min?
BTW, my makefile patch is this, more readable. I see you didn't commit the makefile :)
Code: [Select]

Hi

Sorry, no answers to the above questions but they do cause me to ask: Why can I not see the text in the boxes marked as Code: [Select] using Daves current Dooble build? - see attached dooble_text.jpg

Bad font? What does "fc-match fixed" output? Could try "fc-match -v fixed | less" for more info on the font.
Long term I'd suggest installing some more fonts.
Edit: Also try closing Dooble, run "fc-cache -r", wait till it finishes and try Dooble again
Edit2: Did you install WinOS2 support?

Hi Dave

In my case the program compiled, with your suggested change to vectfont.h. The exe file seems to be working, it is showing different text with different styles, like the origina sample exe.

I'm attaching it.

My next step will be to go after the warnings.

OK, it looks like you fixed a few warnings and you're tree works here. Previous didn't show any of the different text's, just a blank window.

Hi Dave

[L:\]fc-match fixed
HELV.PFB: "Helvetica" "Regular"

fc-cache -r seems to have fixed the problem.


Thanks

Pete
