Java and zlib

Java and zlib

[Gerald Pfeifer]

Due to the following change

  2000-09-02  Anthony Green  <green@redhat.com>

        * jcf-io.c: Include zlib.h.
        (open_in_zip): Read compressed class file archives.

GCC fails to build on several of my "minimal" boxes:

  ../stage1/xgcc -B../stage1/ -B/sw/test/gcc/SunOS/sparc-sun-solaris2.6/bin/ -c  -DIN_GCC  -DSVR4  -O2 -g -O2 -W -Wall  -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes  -Wno-long-long  -W -Wall    -I. -I.. -I/sw/test/gcc/gcc/gcc/java -I/sw/test/gcc/gcc/gcc/java/.. -I/sw/test/gcc/gcc/gcc/java/../config -I/sw/test/gcc/gcc/gcc/java/../../include -I/sw/test/gcc/gcc/gcc/java/../../zlib /sw/test/gcc/gcc/gcc/java/jcf-io.c
  /sw/test/gcc/gcc/gcc/java/jcf-io.c:33:18: zlib.h: No such file or directory

I am aware that there has been a bit of discussion on whether to include
zlib in the tree, but I believe that the current situation is definitely
undesirable.

Problem #1: zlib as a required package is not mentioned anywhere in
our install documentation.

Problem #2: If this is a required package, its existence should be
verified at configure time, instead of aborting the bootstrap after
it's already half through.

(Or should zlib be checked for during configure and only be used if
it is present? If so, still the documentation needs to mention that.)

Your update must not have caught it.

cvs -z4 -q update -dP zlib in the root of your gcc cvs tree ought to
make it appear.

<ouch> 

My bad. I'm completely embarrassed!

Sorry,
Gerald

PS: Perhaps we could have configure abort if it does not find zlib.h?

Maybe you forgot to run ./contrib/gcc_update with the -dP option? zlib _is_ 
part of the tree now and lives in the toplevel.

*shrug*  I don't see that that's any different from
the compilation error that you got.
