grx-2.3.1 and gpc 20000705 - Gpc

6 Jul 2000


      I have some problems compiling some grx-2.3.1 pascal sample test programs
using the latest gpc 20000705.
My system is Sun Sparc Solaris 7. Currently I have two versions of gpc on my
system.
A) Old GPC (and GCC)
/opt/GCC2951/bin/gpc -v
Reading specs from
/opt/GCC2951/lib/gcc-lib/sparc-sun-solaris2.7/2.95.1/specs
gpc version 19991030, based on 2.95.1 19990816 (release)
B) New GPC (and GCC)
/opt/GCC2952/bin/gpc -v
Reading specs from
/opt/GCC2952/lib/gcc-lib/sparc-sun-solaris2.7/2.95.2/specs
gpc version 20000705, based on 2.95.2 19991024 (release)
I have fetched GRX (Graphics) source from the URL below.
http://www.gnu.de/software/GRX/download/grx-2.3.1.tar.gz.
grx-2.3.1 were compiled and (manually) installed to the "Old" and "New"
dir's  using "Old" and "New" GCC respectively; so far no problem.
Problems come when building the sample pascal programs under grx-2.3.1's
pascal directory.
grx-2.3.1/pascal> ls
./               build-examples*  modetest.pas     vir_test.pas
../              grx20.gpi        taste.pas
bgi/             grx20.o          txt_test*
blt_test.pas     grx20.pas        txt_test.pas
Here I have my tiny script "build-examples" to build the *.pas.
grx-2.3.1/pascal> cat build-examples
#!/bin/sh
for pgm in `echo blt_test modetest taste txt_test vir_test`
do
  echo compiling $pgm
  echo /opt/GCC2952/bin/gpc -o $pgm $pgm.pas /opt/GCC2952/lib/libgrx20X.a
-lX11
  /opt/GCC2952/bin/gpc -o $pgm $pgm.pas /opt/GCC2952/lib/libgrx20X.a -lX11
  echo  -----
done
If I use the "Old" gpc from the script (keeping /opt/GCC2952/lib/libgrx20X.a
the same), building were OK.
With the "New" gpc, *no pascal programs were built*; the following were the
script output (see below).
I have no idea why the "init_Grx20" sysmol was not resolved by the "New"
gpc, using the *same* library
(/opt/GCC2952/lib/libgrx20X.a).
