COMPILING FROM SOURCE

Download the latest release from and uncompress it

# Get latest STAR source from releases
wget https://github.com/alexdobin/STAR/archive/2.6.0a.tar.gz
tar -xzf 2.6.0a.tar.gz
cd STAR-2.6.0a

# Alternatively, get STAR source using git
git clone https://github.com/alexdobin/STAR.git

Compile under Linux

# Compile
cd STAR/source
make STAR

Compile under Mac OS X

# Compile
cd source
make STARforMacStatic

All platforms

If g++ compiler (true g++, not Clang sym-link) is not on the path, you will need to tell make where to find it:

# Build STAR
cd source
make STARforMacStatic CXX=/path/to/gcc

If employing STAR only on a single machine or a homogeneously setup cluster, you may aim at helping the compiler to optimize in way that is tailored to your platform. The flags LDFLAGSextra and CXXFLAGSextra are appended to the default optimizations specified in source/Makefile.

# platform-specific optimization for gcc/g++
make CXXFLAGSextra=-march=native
# together with link-time optimization
make LDFLAGSextra=-flto CXXFLAGSextra="-flto -march=native"

LIMITATIONS

This release was tested with the default parameters for human and mouse genomes. Mammal genomes require at least 16GB of RAM, ideally 32GB. Please contact the author for a list of recommended parameters for much larger or much smaller genomes.
