[Zlib-devel] zlib-1.2.3.3 build feedback

[Nelson H. F. Beebe]

The first problem that I noted with the zlib-1.2.3.3 release is that
the configure script does not propagate environment variables that set
CC and CFLAGS.

My automated build procedures (described in Chapter 8 of ``Classic
Shell Scripting''

	http://www.math.utah.edu/~beebe/books/css

) are able to test software on about 25 flavors of Unix in about 125
compilation environments (different compilers and options), but they
are ineffective when CC and CFLAGS settings are ignored.

------------------------------------------------------------------------

On DEC Alpha OSF/1, compilation fails like this:

cc -O   -c -o deflate.o deflate.c
cc: Error: deflate.c, line 516: In this statement, "NULL" is not declared.
(undeclared)
        if (s->gzhead != NULL) {            /* user-supplied gzip header */
-------------------------^

I did a "make clean" followed by "make CC=gcc", and got further:

ar libz.a adler32.o compress.o crc32.o gzio.o uncompr.o deflate.o trees.o
zutil.o inflate.o infback.o inftrees.o inffast.o
ar: illegal option -- z
Usage: ar [-X32_64] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name] [count]
archive-file file...

------------------------------------------------------------------------

On NetBSD 1.6 IA-32, the build failed at the "ar" step:

ar libz.a adler32.o compress.o crc32.o gzio.o uncompr.o deflate.o trees.o
zutil.o inflate.o infback.o inftrees.o inffast.o
ar: illegal option -- z
Usage: ar [emulation options] [-]{dmpqrstx}[abcfilNoPsSuvV] [member-name]
[count] archive-file file...
       ar -M [<mri-script]

------------------------------------------------------------------------

On Solaris 7, 8, 9, and 10 SPARC, and Solaris 10 IA-32, compilation
fails like this:

cc -O   -c -o crc32.o crc32.c
"crc32.c", line 72: syntax error before or at: off64_t
"crc32.c", line 72: warning: undefined or missing type for: off64_t

The same thing happens with "make CC=gcc".
