From f442c1e89e99ae5a0068a2d32e7284c2623f09fd Mon Sep 17 00:00:00 2001 From: Mark Adler Date: Fri, 7 Oct 2011 01:57:07 -0700 Subject: [PATCH] Add a ./config --solo option to make zlib subset with no libary use A common request has been the ability to compile zlib to require no other libraries. This --solo option provides that ability. The price is that the gz*, compress*, and uncompress functions are eliminated, and that the user must provide memory allocation and free routines to deflate and inflate when initializing. --- Makefile.in | 10 ++- configure | 16 ++++ deflate.c | 19 +++-- example.c | 76 ++++++++++++++----- infback.c | 11 ++- inflate.c | 15 +++- minigzip.c | 193 +++++++++++++++++++++++++++++++++++++++++++++++- zconf.h | 106 ++++++++++++++------------ zconf.h.cmakein | 106 ++++++++++++++------------ zconf.h.in | 106 ++++++++++++++------------ zlib.h | 16 +++- zutil.c | 7 ++ zutil.h | 51 +++++++------ 13 files changed, 537 insertions(+), 195 deletions(-) diff --git a/Makefile.in b/Makefile.in index 67375ef..c1c37fe 100644 --- a/Makefile.in +++ b/Makefile.in @@ -54,11 +54,13 @@ man3dir = ${mandir}/man3 pkgconfigdir = ${libdir}/pkgconfig tempfile := $(shell mktemp -u __XXXXXX) -OBJC = adler32.o compress.o crc32.o deflate.o gzclose.o gzlib.o gzread.o \ - gzwrite.o infback.o inffast.o inflate.o inftrees.o trees.o uncompr.o zutil.o +OBJZ = adler32.o crc32.o deflate.o infback.o inffast.o inflate.o inftrees.o trees.o zutil.o +OBJG = compress.o uncompr.o gzclose.o gzlib.o gzread.o gzwrite.o +OBJC = $(OBJZ) $(OBJG) -PIC_OBJC = adler32.lo compress.lo crc32.lo deflate.lo gzclose.lo gzlib.lo gzread.lo \ - gzwrite.lo infback.lo inffast.lo inflate.lo inftrees.lo trees.lo uncompr.lo zutil.lo +PIC_OBJZ = adler32.lo crc32.lo deflate.lo infback.lo inffast.lo inflate.lo inftrees.lo trees.lo zutil.lo +PIC_OBJG = compress.lo uncompr.lo gzclose.lo gzlib.lo gzread.lo gzwrite.lo +PIC_OBJC = $(PIC_OBJZ) $(PIC_OBJG) # to use the asm code: make OBJA=match.o, PIC_OBJA=match.lo OBJA = diff --git a/configure b/configure index 1838846..672b24f 100755 --- a/configure +++ b/configure @@ -54,11 +54,14 @@ includedir=${includedir-'${prefix}/include'} mandir=${mandir-'${prefix}/share/man'} shared_ext='.so' shared=1 +solo=0 zprefix=0 build64=0 gcc=0 old_cc="$CC" old_cflags="$CFLAGS" +OBJC='$(OBJZ) $(OBJG)' +PIC_OBJC='$(PIC_OBJZ) $(PIC_OBJG)' while test $# -ge 1 do @@ -81,6 +84,7 @@ case "$1" in -i* | --includedir) includedir="$2";
