Getting Started


Pre-built binaries

Pre-built binaries for Linux and macOS on x86_64 are available alongside each release. We also have a script for downloading and installing pre-built versions:

/bin/bash -c "$(curl -fsSL"

This will install Seq in a new .seq directory within your home directory. Be sure to update ~/.bash_profile as the script indicates afterwards!

Seq binaries require a libomp to be present on your machine. brew install libomp or apt install libomp5 should do the trick.

Building from source

See Building from Source.


The seqc program can either directly run Seq source in JIT mode:

seqc myprogram.seq

or produce an LLVM bitcode file if a -o <out.bc> argument is provided. In the latter case, llc and the system compiler can be used to convert the bitcode file to an object file and link it to produce an executable, respectively:

seqc -o myprogram.bc myprogram.seq
llc myprogram.bc -filetype=obj -o myprogram.o
gcc -L/path/to/libseqrt/ -lseqrt -lomp -o myprogram myprogram.o

This produces a myprogram executable.

Interfacing with C: If a Seq program uses C functions from a particular library, that library can be specified via a -L/path/to/lib argument to seqc. Otherwise it can be linked during the linking stage if producing an executable.
