Hi Dave

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

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


Thanks

Pete

Bad cache. fc-cache -r really forces all fontconfig caches to be rebuilt. fc-cache or fc-cache -f might have been good enough.
Edit: Helvetica isn't really a good choice for fixed, but must be the best that fontconfig can find.

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.
Edit: Seems that your changing a couple of USHORT's to ULONG's in VECTFONT.C fixed it.


Thanks Dave. I didn't notice that ULONG change will benefit the program in that way.

I need some help to try to get out the warnings, What do you suggest me with this " CHAR * {aka char *}" warning?
I had try to change the declaration to "unsigned char" but it generates more warning.

Quote
vf00.c: In function 'QueryStartPointInTextBox':
vf00.c:90:36: warning: pointer targets in passing argument 3 of 'GpiQueryTextBox' differ in signedness [-Wpointer-sign]

      |                                                       ~~~~^~~~~~~~~

My goal is to leave this sample as good as possible to compile with GCC and the .h that we have on the RPM.

Hi
I had reduced the number of warnings of  "szText".
I just have 9 warnings left, but I'm stuck there.

Try this one. Did some casts and added a bunch of curly brackets.

Thank you Dave for the casting lesson. It compiles beautifully now without any warnings.

I will prepare the file with a readme and upload it to github.

Hi

Moving to the next one:
https://github.com/OS2World/DEV-SAMPLES-PM-Slider

This is an older sample, I recreated the makefile, since it looked in a format I don't know about.
I think I solved the warnings.

I'm still not sure how it looks, I'm getting this issue with the wrc.

Code: [Select]
[C:\DEV\DEV-SAMPLES-PM-SLIDER]make   2>&1  | tee make.out
gcc -Wall -Zomf -c -O2 slider.c -o slider.obj
wrc -r slider.rc
Open Watcom Windows and OS/2 Resource Compiler Version 2.0beta1 LA

slider.rc(30): Error! E049: Syntax error near "0x00000100L "
make: *** [slider.res] Error 8

Trying with rc instead of wrc, I get
Code: [Select]
Creating binary resource file slider.RES
RC:  RCPP -E -D RC_INVOKED -W4 -f slider.rc -ef W:\OS2\RCPP.ERR -I W:\usr\include\os2tk45\inc -I W:\usr\include\os2tk45\gl -I W:\usr\include\os2tk45
slider.rc(36) : fatal error C1004: unexpected EOF
make: *** [makefile:17: slider.res] Error 3

Fixed by adding an EOL (blank line) at the end of the rc file. Wrc stll fails.
Was there a reason that you named the binary vectfont.exe? Seems it should be slider.exe.
Now the error is
Code: [Select]
Creating binary resource file slider.RES
RC:  RCPP -E -D RC_INVOKED -W4 -f slider.rc -ef W:\OS2\RCPP.ERR -I W:\usr\includ

slider.rc

Hi Dave

vectfont.exe was my mistake on the makefile. I fixed it, includes the EOL on the rc file and now I get this.

Code: [Select]
gcc -Wall -Zomf -c -O2 slider.c -o slider.obj
wrc -r slider.rc

Yes, I'm still using rc.exe for now until I research.
You had two slider.obj in the linker line in the makefile causing the duplicate main() error.
Then need to remove the export in the DEF file to get rid of
Code: [Select]
weakld: error: Unresolved symbol (UNDEF) 'ClientWndProc
Then slider.exe works.

The rc file is missing a | after SLS_READONLY on line 30. Strange that rc is fine with that but not wrc.

Hi Dave

If I remove .DEF from the make file, and add the | after SLS_READONLY, it will compile. But my slider.exe just loads and quit without working.

I get this message now with RC:

Quote

[C:\DEV\DEV-SAMPLES-PM-SLIDER]make   2>&1  | tee make.out
gcc -Wall -Zomf -c -O2 slider.c -o slider.obj
gcc -Zomf slider.obj slider.res -o slider.exe
Compile ending.
RC is reading the binary resource file C:\dev\DEV-SAMPLES-PM-Slider\slider.res.

RC :Warning 3014: RC found a resource type equal to zero.
RC :Error 1003:RC had an I/O error with file .

make: *** [slider.exe] Error 1

slider.exe compiles.

Are you mixing rc.exe and wrc.exe? I used rc.exe to troubleshoot and then reverted to wrc, have to keep the environmental variables in sync with the makefile.
Here's the same package without doing make clean, slider.exe works here.
