Thanks for your help! Following the installation instructions, I was able to run "make -f makefile.x11" apparently without errors. I used the following choices when editing makedefs.grx:

HAVE_LIBTIFF=y HAVE_LIBJPEG=y HAVE_LIBPNG=y NEED_ZLIB=y INCLUDE_PRINTING_CODE=n INCLUDE_BMP_CODE=y INCLUDE_GPC_SUPPORT=y INCLUDE_SHARED_SUPPORT=y INCLUDE_BGI_SUPPORT=y HAVE_UNIX_TOOLS=n BUILD_X86_64=n

you should put BUILD_X86_64=y here since you have an AMD 64 computer

I left the rest of the makedefs.grx file alone.

Then I went into the /test subdirectory and here is the log:

david@Achernar:~/software/grx/grx248/grx248/test$ sudo make -f makefile.x11 [sudo] password for david: gcc -c -O2 -fno-strict-aliasing -Wall -m32 -D__XWIN__ -I../include arctest.c -o arctest.o

-m32 option appears when you compile for 32 bits even on a 64 bits computer. This is possible in fact, but you have to install all libraries (and gpc) in the 32 bits version.

In file included from arctest.c:21: test.h: In function ‘main’: test.h:88: warning: ignoring return value of ‘fgets’, declared with attribute warn_unused_result gcc -s -m32 -s -o xarctest arctest.o ../lib/unix/libgrx20X.a -ltiff -ljpeg -lpng -lz -L/usr/X11R6/lib -lX11 -lm /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.3/../../../libz.so when searching for -lz /usr/bin/ld: skipping incompatible /usr/lib/gcc/x86_64-linux-gnu/4.3.3/../../../libz.a when searching for -lz /usr/bin/ld: skipping incompatible /usr/lib/libz.so when searching for -lz /usr/bin/ld: skipping incompatible /usr/lib/libz.a when searching for -lz /usr/bin/ld: cannot find -lz collect2: ld returned 1 exit status make: *** [xarctest] Error 1

These messages say that it has not found the 32 bits versions of libz
