If anyone has solved the error: conflicting types for 'exp' or the equivalent for 'log', I'd be incredibly grateful.

[Richard Finney]

Is the conflicting types a warning or an error ?
Can you display the full message?

If it's just a warning, don't worry about it.

I don't quite know what's important, so there's all of it.

[Philcolson]

Figured it out! I put in, from somewhere I found online, the -Dexpl=exp -Dlogl=log line in DFLAGS. Got rid of that and it worked! Thanks!

I was having the same problem running make in Ubuntu 12.04 lts, with errors resulting from problems with both zlib and curses. Ultimately the solution was to do this:

sudo apt-get update
sudo apt-get install zlib1g-dev libncurses5-dev
sudo make clean
sudo make

[Philcolson]

Thanks, NRP! I'll pass that onto anyone having a similar problem!

[NicolaLosito]

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

On an Ubuntu box if you install the libncurses5 and libncurses5-dev the -I parameter is useless…

[seqie]

there are installation instructions in the file "INSTALL":
The text-based viewer (tview) requires the GNU ncurses library
<http://www.gnu.org/software/ncurses/>, which comes with Mac OS X and most of
the modern Linux/Unix distributions. If you do not have this library installed,
you can still compile the rest of SAMtools by manually changing:
`-D_CURSES_LIB=1' to `-D_CURSES_LIB=0' at the line starting with `DFLAGS=', and
comment out the line starting with `LIBCURSES='.

Worked for me (Ubuntu 12.04)

When it comes to running packages like samtools, bedtools or any other kind of bioinformatics solution on a Windows box, you're better off getting VMWare and installing Ubuntu. Trying to compile things from source with Cygwin is asking for trouble.
