Mark Adler	2dadd2fab4	Use name in GCC_CLASSIC as C compiler for coverage testing, if set. Apple removed support for gcov in the default gcc compiler chain, when they moved to llvm. This can be circumvented in XCode 4.2 by using the gcc chain with gcc-4.2. This patch allows setting GCC_CLASSIC to the name of a real gcc executable (e.g. "gcc-4.2") to allow coverage testing.	2012-02-04 10:00:48 -08:00
Mark Adler	f9e4edc996	Avoid library header include in crc32.c for Z_SOLO. crc32.c was #including limits.h in order to find a four-byte integer type. It was doing this even if Z_SOLO were defined, violating the intent of Z_SOLO, which is to include no library headers and require no library functions. Now crc32.c obeys the intent of Z_SOLO, but with the downside that crc32() will be slower than when not compiled with Z_SOLO. This can be remedied manually by typedefing u4 to a known four-byte unsigned integer type, and #defining BYFOUR in crc32.c.	2012-02-01 23:55:29 -08:00
Mark Adler	55b8b5fec1	Put gzflags() functionality back in zutil.c. gzflags() was put in gzwrite.c in order to be compiled exactly the same as gzprintf(), so that it was guaranteed to return the correct information. However that causes a static linkage to zlib to bring in many routines that are often not used. All that is required to duplicate the compilation environment of gzprintf() is to include gzguts.h. So that is now done in zutil.c to assure that the correct flags are returned.	2012-02-01 23:25:34 -08:00

Mark Adler	22eb01184f	Have gzputc return the character written instead of the argument. When successful, gzputc would return the second argument. If the second argument were -1, gzputc would return -1 instead of the character written, which was 255. However the -1 would not be distinguishable from an error. Now gzputc returns 255 in that case.	2012-01-29 09:47:29 -08:00

Jonathan Nieder	32d8a5379e	Add an --enable-demos option to contrib/minizip/configure. This makes build-testing and installing the minizip/miniunzip programs as simple as "autoreconf -if && ./configure --enable-demos && make && make install". Without --enable-demos, the makefile will only build and install the library, as before. Helped by Mike Frysinger. minizip/miniunzip were not intended to be general-purpose installed utilities, but they can be useful from time to time as a lightweight substitute for zip/unzip. You can also use them to quickly test that the library installation procedure worked.	2012-01-21 17:15:48 -08:00
Jonathan Nieder	f0cff24214	Add support for VPATH builds in contrib/minizip. Instead of using relative paths directly, use paths relative to top_srcdir and top_builddir to refer to source files and built files, respectively. Note that the toplevel zlib configure script still does not have any special support for out-of-tree builds. But now you can do (cd contrib/minizip && autoreconf -fis) mkdir -p BUILD/test cp .c .h .in zlib.map configure zlib.3 BUILD cp test/.c BUILD/test (cd BUILD && ./configure --shared) (cd BUILD && make) mkdir -p BUILD/contrib/minizip cd BUILD/contrib/minizip ../../../contrib/minizip/configure make While at it, move the include path and library path settings to CPPFLAGS and LDFLAGS respectively instead of setting both in CFLAGS. Thanks to Mike Frysinger for advice.	2012-01-21 12:56:57 -08:00
Jonathan Nieder	81015585d2	Add missing libs to minizip linker command. Trying to build the minizip utility from contrib/minizip after an autoreconf -f: libtool: link: gcc -g -O2 -o minizip minizip.o minizip.o: In function `getFileCrc': /tmp/zlib/contrib/minizip/minizip.c:211: undefined reference to `crc32' minizip.o: In function `main': /tmp/zlib/contrib/minizip/minizip.c:378: undefined reference to `zipOpen64' /tmp/zlib/contrib/minizip/minizip.c:451: undefined reference to `zipOpenNewFileInZip3_64' /tmp/zlib/contrib/minizip/minizip.c:502: undefined reference to `zipCloseFileInZip' /tmp/zlib/contrib/minizip/minizip.c:509: undefined reference to `zipClose' /tmp/zlib/contrib/minizip/minizip.c:485: undefined reference to `zipWriteInFileInZip' collect2: error: ld returned 1 exit status The cause: contrib/minizip/Makefile.am does not specify that minizip needs to be linked to libminizip. With some linkers (e.g., GNU binutils without --copy-dt-needed-entries), an indirect dependency cannot be used to resolve symbols, so link to libz for crc32(), too.	2012-01-21 12:46:25 -08:00
Jonathan Nieder	ad88c19baa	Add -I../.. -L../.. to CFLAGS for minizip and miniunzip. Trying to build miniunzip utility from contrib/minizip after an autoreconf -f produces [...] In file included from minizip.c:61:0: zip.h:50:18: fatal error: zlib.h: No such file or directory unless zlib is already installed. Use AM_CFLAGS to set the include path and library path to point to the just-build copy of zlib to fix this. (This was already done for libminizip but not the binaries that use it before this patch.)	2012-01-21 12:45:38 -08:00

Mark Adler	2d55657c03	Have ./configure use the compiler return code for error indication. Previously ./configure would use any output on stderr as an indication that the compilation failed. However if some compiler wrapper uses stderr for some other purpose, e.g. distcc for nodes going down, then ./configure would not properly configure the build. This problem was noted by Mike Frysinger. For backwards compatibility, ./configure will revert to the old way, i.e. checking for anything on stderr, if when it deliberately runs the compiler with an error, a zero exit status is returned.	2012-01-16 16:44:40 -08:00
