Building msieve under Ubuntu 12.04

[VolMike]

I'm trying to build msieve under under Ubuntu 12.04 x86
If "make x86", system returns :

make: svnversion: Command not found
gcc -D_FILE_OFFSET_BITS=64 -O3 -fomit-frame-pointer -march=k8 -DNDEBUG -D_LARGEFILE64_SOURCE  -Wall -W -DMSIEVE_SVN_VERSION="\"unknown\"" -I. -Iinclude -Ignfs -Ignfs/poly -Ignfs/poly/stage1 -c -o common/filter/clique.o common/filter/clique.c
In file included from include/msieve.h:24:0,
                 from include/common.h:18,
                 from common/filter/filter.h:23,
                 from common/filter/filter_priv.h:23,
                 from common/filter/clique.c:15:
include/util.h:47:19: fatal error: zlib.h: No such file or directory
compilation terminated.
make: *** [common/filter/clique.o] Error 1

Zlib folder is in msieve folder and zlib.h exists in zlib.

I'm newbie in Linux systems, but it seems that msieve needs some other zlib files.How to get rid of this error and build msieve?

Add -Izlib to makefile next to -I. -Iinclude -Ignfs

Thanks!
It makes compilation proceed, libmsieve.a was successfully created, but then system retuns another error

ar: creating libmsieve.a
ranlib libmsieve.a

What's wrong with lz?

On most other unix systems zlib is a library called libz.a or libz.so; you link it in by adding '-lz' to the compile line. But you've already done that, so you can go into the makefile and remove the part that adds '-lz'.

[debrouxl]

If you want to compile against the zlib on your host system, you'll have to install the zlib1g-dev package.

Thanks, but it seems int this case not only -lz should be removed. The most easiest way is to install zlib1g-dev as debrouxl mentioned.

You can also compile it with NO_ZLIB=1 in the make command.

Thanks! I was successfull in msieve compilation after installing this package.

In addition to the above comments, suppose we were on a machine where we have no sudo -or- even if you have the system libz, but it is old (VER<=1.2.3). The zlib folder is included, indeed, for that reason (and for Windows builds). You want to cd zlib; make, then copy libz.a to the msieve folder and replace -lz with ./libz.a in the Makefile and you will have libz built-in. There's no harm in doing -- libz code is tiny. It will not bloat the binary or the memory image.

As I'm newbie in Linux systems, it seems too complicated for me to keep in mind all those features. Honestely, I didn't think it would be so difficult to me to make msieve build. The main reason of that is a deficit of Linux knowledges.
