Installing Bio::DB::Sam perl module

Question

I am trying to install a perl module Bio::DB::Sam on my home directory on a remote server.

I downloaded the module, extracted the files, and ran:

Answer 1

Here is a script that will fetch the SAMtools source and compile it, then fetch and compile the Perl bindings.

wget http://sourceforge.net/projects/samtools/files/samtools/0.1.18/samtools-0.1.18.tar.bz2
tar xjf samtools-0.1.18.tar.bz2 && cd samtools-0.1.18
make CFLAGS=-fPIC
export SAMTOOLS=`pwd`
cpanm Bio::DB::Sam

Part of the problem you were likely seeing is that the SAMtools project has recently undergone some major code reorganization (and this has naturally made it difficult to work with external language bindings).

Answer 2

[Solved]

wget http://sourceforge.net/projects/samtools/files/samtools/0.1.18/samtools-0.1.18.tar.bz2

tar xjf samtools-0.1.18.tar.bz2 && cd samtools-0.1.18

make CFLAGS=-fPIC

enter cpan in terminal and enter

install Bio::DB::Sam

Be carefully:

You can not use the following command:

perl -MCPAN -Mlocal::lib -e 'CPAN::install(Bio::DB::Sam)'

You can only use cpan and then use

install Bio::DB::Sam

Answer 3

I fixed this issue by remaking samtools with the -fPIC parameter

make clean
make CXXFLAGS=-fPIC CFLAGS=-fPIC CPPFLAGS=-fPIC

then installed using cpan.

cpan[2]> install Bio::DB::Sam 

Answer 4

I followed instructions from README file below of Bio-SamTools-1.43 to edit the Makefile in samtools 0.1.17. Then, to install, I used

perl -MCPAN -e shell install Bio::DB::Sam

README:

This is a Perl interface to the SAMtools sequence alignment interface. It ONLY works on versions of Samtools up to 0.1.17. It does not work on version 1.0 or higher due to major changes in the library structure.

See http://samtools.sourceforge.net/ for samtools documentation.

• ONE-STEP INSTALLATION

In the root directory of this distribution you will find the script INSTALL.pl. Running this will download the latest versions of this module and SamTools into a temporary directory, compile them, test and install. Simply run:

perl INSTALL.pl

• MULTI-STEP INSTALLATION

The more traditional install requires you to separately download, unpack and compile SAMtools 0.1.10 through 0.1.17 in some accessible directory. Typing "make" in the samtools directory will usually work. SAMtools versions 0.1.18 and higher do not work with this library.

Then set the environment variable SAMTOOLS to point to this directory.

You will also need to install Bio::Perl from CPAN.

Now run:

perl Build.PL ./Build ./Build test (sudo) ./Build install

TROUBLESHOOTING:

If you encounter problems during compiling, you may need to edit Build.PL so that extra_compiler_flags matches the CFLAGS and DFLAGS settings in the Samtools Makefile. Here are some common problems:

1. When building this module, you get an error like the following: relocation R_X86_64_32 against `a local symbol' can not be used when making a shared object; recompile with -fPIC

To fix this, edit the Makefile in the Samtools distribution by adding "-fPIC" to the CFLAGS line. While you're at it, you may also wish to get rid of a bunch of unused variable warnings that appears under recent versions of gcc. The modified CFLAGS will look like this

CFLAGS= -g -Wall -Wno-unused -Wno-unused-result -O2 -fPIC #-m64 #-arch ppc

Then do "make clean; make" in the Samtools directory to recompile the library. After this you should be able to build this module without errors.

2. When building this module, you get an error about a missing math library.

To fix this, follow the recipe in (1) except add -m64 to CFLAGS so it looks like this:

CFLAGS= -g -Wall -O2 -fPIC #-m64 #-arch ppc

TESTING AND CONTRIBUTING:

You can obtain the most recent development version of this module via its GitHub site at https://github.com/GMOD/GBrowse-Adaptors. Please feel free to submit bug reports, patches, etc. via GitHub.
