You are right. It's -lgrx20 (even with GRX23).
I know now that I have no problems with GRX23 :
I can compile all the demo programs with this command.

But... I'm still having linking problems with BCC2GRX and BGI2GRX. I
spend a long time wandering through FAQs and Info files, and trying to
change parameters in my configuration (I restored the djgpp.djl file
in DJGPP\lib\, because it seems I need it) :
no results !

I can compile all the BCC2GRX demo files except one : bccbgi.c :

My command : gcc -o bccbgi.exe bccbgi.c -lbcc2 -lgrx20
The result :
c:/djgpp/tmp\cccyfwgg(.text+0x656):bccbgi.c: undefined reference to
`setrgbdefaults'
c:/djgpp/tmp\cccyfwgg(.text+0x19e6):bccbgi.c: undefined reference to

With BGI2GRX, I always have the same messages when I run make_all.bat
(to compile demo files) :
C:\DJGPP\travail>call gpcbgi modelist --automake  

C:\DJGPP\travail>gpc modelist.pas -omodelist -lbcc2 -lgrx20 --automake

[... long list of errors]

I tried : gpc -o bgi2grx.exe --automake -g bgi2grx.pas -lbcc2 -lgrx20
but I get :
c:\djgpp\lib\crt0.o(.data+0xc2):crt0.s: undefined reference to `main'
c:\djgpp\lib/libc.a(crt1.o)(.text+0x44e):crt1.c: undefined reference
to `main'

I AM LOST :-(
