Mohammed,
Having just been trying to build 0.93 on Solaris 8 myself, I can perhaps
shed a bit more light on this.
There appear to be (at least) four distinct issues here
1) libbz2.so exists on native Solaris since Solaris 8 (maybe 7?). The
version on Sol8 is old:-
$ bzip2 -V
bzip2, a block-sorting file compressor. Version 0.9.0c, 18-Oct-98.
and does not include the BZ2_ interfaces that you are seeking:-
$ nm /usr/lib/libbz2.so | grep -i bzdecompress
[160] | 36724| 464|FUNC |GLOB |0 |9 |bzDecompress
[173] | 37188| 172|FUNC |GLOB |0 |9 |bzDecompressEnd
[158] | 32656| 232|FUNC |GLOB |0 |9 |bzDecompressInit
Contrast this with Solaris 9 and 10:-
$ bzip2 -V
bzip2, a block-sorting file compressor. Version 1.0.2, 30-Dec-2001.
$ /usr/ccs/bin/nm /usr/lib/libbz2.so | grep -i bzdecompress
[133] | 46756| 520|FUNC |GLOB |0 |9 |BZ2_bzDecompress
[174] | 47276| 180|FUNC |GLOB |0 |9 |BZ2_bzDecompressEnd
[181] | 42760| 276|FUNC |GLOB |0 |9 |BZ2_bzDecompressInit
[158] | 52400| 12|FUNC |GLOB |0 |9 |bzDecompress
[161] | 52412| 12|FUNC |GLOB |0 |9 |bzDecompressEnd
[199] | 52388| 12|FUNC |GLOB |0 |9 |bzDecompressInit
where the interfaces are defined both with and without a BZ2_ prefix
2) There is code in the 'configure' script which decides whether to define
NOBZ2PREFIX in clamav-config.h. This decision is based on the existence on
the interface bzReadOpen() [in the library libz2.so]. For Sol 8/9/10 it is
going to set
#define NOBZ2PREFIX 1
To my mind it ought instead to base the decision, at least in part, on the
NON-existence of the interface BZ2_bzReadOpen. This would give different
answers for 8 vs 9/10 (where nm gives results analogous to those for
bzcompress above). (Caveat: that would work for Solaris; I can't speak
for any other OS). However, fixing this would not help you, since it is
already making the correct decision for Sol 8.
3) Based on some comparable code that I found in libclamav/scanners.c, I
have applied the following patch to libclamav/unzip.c:-
$ diff -c libclamav/unzip.c.orig libclamav/unzip.c
*** libclamav/unzip.c.orig Wed Apr 2 21:17:27 2008
--- libclamav/unzip.c Sun Apr 27 15:28:33 2008
***************
*** 177,182 ****
--- 177,189 ----
#if HAVE_BZLIB_H
+
+ #ifdef NOBZ2PREFIX
+ #define BZ2_bzDecompressInit bzDecompressInit
+ #define BZ2_bzDecompressEnd bzDecompressEnd
+ #define BZ2_bzDecompress bzDecompress
+ #endif
+
case ALG_BZIP2: {
bz_stream strm;
memset(&strm, 0, sizeof(strm));
... and 'make' now runs to completion. (Caveat: I haven't run 'make
install' yet, for unrelated reasons, so cannot say for certain that this
fixes anything)
4) What I do not understand at all is the relationship, if any, between
all of the above and the code in libclamav/nsis/, which appears to include
source code for bzip2/libbz2 (version 1.0.4). If the latter is supposed to
be used, why is 'configure' even looking at system versions? And it always
bothers me when code is potentially included from two different locations.
(It may be perfectly ok; I don't know enough to know one way or the other)
HTH,
Richard
