Samtools installation

[SeqVicious]

Hi all,

I'm very new to bioinformatics and all I'm trying to do is index a bam file so I can view the pileup in IGV. I've downloaded the latest version of samtools unpacked it successfully. I'm now trying to install it but I'm running into an error after the 'make samtools' command. Make clean works just fine but the following error occurs after 'make samtools'.

$ make samtools
make[1]: Entering directory <path>
gcc -c -g -Wall -O2 -D_FILE_BITS=64 -D_LARGEFILE64_SOURCE -D_USE_KNETFILE -D_CURSES_LIB=1 -I. bgzf.o
In file included from bgzf.c:36:0:
gbzf.h:29:28: fatal error: zlib.h: No such file or directory
compilation terminated
Makefile:21: recipe for target 'bgzf.o' failed
make[1]: *** [bgzf.o] Error 1
make[1]: Leaving directory <path>
$CC= gcc
gcc: no input filesr] Error 1

It looks like it's having trouble with one of the files. Since I only need to be using a few of the samtools options can I just delete the files that give problems? I've also tried redownloading samtools a couple of times and the same error shows up.

Hi, you don't have zlib in your system. Could you tell me in what operating system are you installing Samtools?

[SeqVicious]

I'm on windows 7 and I'm using cygwin. I just installed zlib by updating cygwin and the command got much further. This time curses.h failed and the command was terminated. I'll try installing curses.h to see if that works.

[SeqVicious]

I installed anything with the name 'curses' in it during the cygwin installation and I'm still getting the following right before termination.

gcc -c -g -Wall -O2 -D_FILE_BITS=64 -D_LARGEFILE64_SOURCE -D_USE_KNETFILE -D_CURSES_LIB=1 -I. bam_tview.c -o bam_tview.o
bam_tview.c:5:20: fatal error: curses.h: No such file or directory
compilation terminated
makefile:21: recipe for target 'bam_tview.o' failed
make:** [bam_tview.o] Error 1

I can't find curses.h to install in cygwin. I don't know what else to do from here.

[Carlos Borroto]

Sorry I don't use cygwin so I won't be of much help. Did you try installing libncurses-devel? I see there are several packages in cygwin for it.

[SeqVicious]

Thanks for trying, Carlos.

I found a fix suggested on another post but I have no idea how to implement it. The fix is adding

CC= gcc
CFLAGS= -g -Wall -O2 #-m64 #-arch ppc
CFLAGS= -I/usr/include/ncurses
DFLAGS= -D_FILE_OFFSET_BITS=64 -D_USE_KNETFILE -D_CURSES_LIB=1 -Dexpl=exp -Dlogl=log
KNETFILE_O= knetfile.o

to Makefile. I found three makefiles and none of them had any CFLAGS in the file. Is it even possible to install samtools on windows?

[Richard Finney]

CFLAGS should be on the second line of the make file (Makefile)...

Makefile should be modified like this ...
CFLAGS= -g -Wall -O2 -I/usr/include/ncurses
DFLAGS= -D_FILE_OFFSET_BITS=64 -D_USE_KNETFILE -D_CURSES_LIB=1 -Dexpl=exp -Dlogl=log

You'll also need to append the text -Dexpl=exp -Dlogl=log to the DFLAGS line the Makefile in bcftools


ALSO !!!! run "make clean" or remove all the .o (object) files before re-making.

[SeqVicious]

Thank you Richard Finney. I just made these corrections and the make samtools command finished. Unfortunately, when I try to use samtools the samtools command cannot be found. Did something go wrong when I made the executable?

[Richard Finney]

type "./samtools" (from cygwin) in the directory you made samools in.

If that does not work, try "./samtools.exe" .

[SeqVicious]

Thank you for your help, it's all working now

[Brian E]

I had a similar problem with getting samtools to work on Cygwin, only my error was:

bam_tview.c:5:20: fatal error: curses.h: No such file or directory

The fix was modifying the makefiles as Richard Finney suggested.
Thanks Richard.

I find another solution of this problem. Before compiling samtools, we can fix the 16th line of Makefile like this"LIBCURSES= -lncurses # -lXCurses". P.S. My operating system is openSUSE.

I followed this advice, but I get
In file included from /usr/include/math.h:146:0,
from bam_md.c:5:
/usr/include/x86_64-linux-gnu/bits/mathcalls.h:101:1: error: conflicting types for ‘exp’

[pag]

may have solved this one
sudo ln -s /lib/x86_64-linux-gnu/libncurses.so.5 /lib/x86_64-linux-gnu/libncurses.so

CFLAGS= -g -Wall -O2 -I/usr/include/ncurses #-m64 #-arch ppc
DFLAGS= -D_FILE_OFFSET_BITS=64 -D_LARGEFILE64_SOURCE -D_USE_KNETFILE -D_CURSES_LIB=0
LIBCURSES= -lncurses # -lXCurses


I also installed libcurses-perl and zlib-bin via ubuntu software center prior to getting this to work

note that
$ make test
make: *** No rule to make target `test'. Stop.
$ make check
make: *** No rule to make target `check'. Stop.
$ make install
make: *** No rule to make target `install'. Stop.

so, just the "make" itself is enough to install it?

I'm also using cygwin and followed the advices above (changed the Makefile, installed ncurses, zlib), but still got the error:

I installed everything with the name zlib, but cannot get further
