Installation of htslib


dhtslib relies on htslib. htslib relies on a handful of compression and web-access libraries: zlib, bzip2, lzma, curl, and ssl. Technically htslib can be built without some of these libraries, though to get all the benefits of dhtslib we recommend installing all of them. For more information you can visit the htslib repository.
To intall htslib dependencies:
Debian / Ubuntu
sudo apt-get update # Ensure the package list is up to date
sudo apt-get install autoconf automake make gcc perl zlib1g-dev libbz2-dev liblzma-dev libcurl4-gnutls-dev libssl-dev
Note: libcurl4-openssl-dev can be used as an alternative to libcurl4-gnutls-dev.
RedHat / CentOS / Amazon Linux
sudo yum install autoconf automake make gcc perl-Data-Dumper zlib-devel bzip2 bzip2-devel xz-devel curl-devel openssl-devel
Alpine Linux
sudo apk update # Ensure the package list is up to date
sudo apk add autoconf automake make gcc musl-dev perl bash zlib-dev bzip2-dev xz-dev curl-dev libressl-dev
sudo zypper install autoconf automake make gcc perl zlib-devel libbz2-devel xz-devel libcurl-devel libopenssl-devel
brew install xz autoconf automake
libdeflate can also be installed for faster (de)compression but is optional.

htslib build and install

You will then need to download htslib (latest release here). As of now we support versions >=1.10. To install htslib:
curl -o htslib-1.12.tar.bz2
tar -xjf htslib-1.12.tar.bz2
cd htslib-1.12
sudo make install
htslib is also linked as a submodule in the dhtslib repo and potentially could be used as it reflects the currently supported version (you must git clone recursively).
cd htslib
autoreconf -i
sudo make install


dub linking issues

By default htslib is dynamically linked to dhtslib via dub.Sometimes it is necessary to specify the LIBRARY_PATH or LD_LIBRARY_PATH environment variables in order for dub and the D compilers to find your htslib installation. This could also apply if your htslib isn't a standard install under /usr/local/lib.
LIBRARY_PATH=/usr/local/lib dub build
LD_LIBRARY_PATH=/usr/local/lib LIBRARY_PATH=/usr/local/lib dub build

Statically linking to htslib

libhts.a needs to be added to your project's source files. Remember to link to all dynamic libraries configured when htslib was built. This may include bz2, lzma, zlib, deflate, crypto, pthreads, curl. Finally, if statically linking, the -lhts flag needs to be removed from compilation by selecting the dub configuration source-static as the dub configuration type for dhtslib within your own project's dub configuration file:
"subConfigurations": {
"dhtslib": "source-static"
