Notice: Development on libstorj is currently on pause during our v3 rearchitecture. Please see https://github.com/storj/storj for ongoing v3 development.
libstorj
Asynchronous multi-platform C library and CLI for encrypted file transfer on the Storj network.
Feature Highlights
- Asynchronous I/O with concurrent peer-to-peer network requests for shards
- Erasure encoding with reed solomon for data durability
- Robust handling of shard transfers by selecting alternative sources
- File integrity and authenticity verified with HMAC-SHA512
- File encryption with AES-256-CTR
- File name and bucket name encryption with AES-256-GCM
- Proxy support with SOCKS5, SOCKS4, SOCKS4a
- Asynchronous progress updates in bytes per file
- Transfers can be cleanly canceled per file
- Seed based file encryption key for portability between devices
- Reference implementation for SIP5 file standard

These notes are for cross compiling for various systems from a Debian based linux distribution, specifically Ubuntu 16.04. The mingw toolchain is used to build for Windows and clang and cctools for macOS builds.
Windows
Supported hosts include:
- x86_64-w64-mingw32
- i686-w64-mingw32
Dependencies:
apt-get install gcc-mingw-w64-x86-64 gcc-mingw-w64-i686 g++-mingw-w64-i686 g++-mingw-w64-x86-64

ARM GNU/Linux
Supported hosts include:
- arm-linux-gnueabihf
- aarch64-linux-gnu
Many ARM based distributions are based on Debian Jessie that includes [email protected]. It may be necessary to cross compile using Ubuntu 14.04. This can be accomplished using chroot (see the documentation at https://help.ubuntu.com/community/BasicChroot).
Once chroot is setup, you'll likely need to install a few additional tools (in addition to the main dependencies listed above):
apt-get install git bsdmainutils
And then install ARM toolchain dependencies:
apt-get install gcc-arm-linux-gnueabihf g++-arm-linux-gnueabihf gcc-aarch64-linux-gnu g++-aarch64-linux-gnu
cd ./depends
make HOST="arm-linux-gnueabihf"
Configure command for libstorj-c:
PKG_CONFIG_LIBDIR="$(pwd)/depends/build/arm-linux-gnueabihf/lib/pkgconfig" CFLAGS="-I$(pwd)/depends/build/arm-linux-gnueabihf/include -L$(pwd)/depends/build/arm-linux-gnueabihf/lib -static -std=gnu99" ./configure --with-pic --host=arm-linux-gnueabihf --enable-static --disable-shared --prefix=$(pwd)/depends/build/arm-linux-gnueabihf
64-bit GNU/Linux
Supported hosts include:
- x86_64-pc-linux-gnu
cd ./depends
make HOST="x86_64-pc-linux-gnu"
Configure command for libstorj-c:
PKG_CONFIG_LIBDIR="$(pwd)/depends/build/x86_64-pc-linux-gnu/lib/pkgconfig" CFLAGS="-I$(pwd)/depends/build/x86_64-pc-linux-gnu/include -L$(pwd)/depends/build/x86_64-pc-linux-gnu/lib -static" ./configure --host=x86_64-pc-linux-gnu --with-pic --enable-static --disable-shared --prefix=$(pwd)/depends/build/x86_64-pc-linux-gnu
Note: --enable-shared will also work
32-bit GNU/linux
Supported hosts include:
- i686-pc-linux-gnu
Dependencies:
apt-get install gcc-multilib g++-multilib
cd ./depends
make HOST="i686-pc-linux-gnu"
Configure command for libstorj-c:
PKG_CONFIG_LIBDIR="$(pwd)/depends/build/i686-pc-linux-gnu/lib/pkgconfig" CFLAGS="-I$(pwd)/depends/build/i686-pc-linux-gnu/include -L$(pwd)/depends/build/i686-pc-linux-gnu/lib -static -m32" LDFLAGS="-m32" ./configure --host=i686-pc-linux-gnu --with-pic --enable-static --disable-shared --prefix=$(pwd)/depends/build/i686-pc-linux-gnu
Note: --enable-shared will also work
Mac OSX
The Apple SDK MacOSX10.11.sdk is needed and is available in Xcode_7.3.1.dmg (requires a developer account). You can extract the sdk using ./depends/extract-osx-sdk.sh:
apt-get install p7zip-full sleuthkit
./depends/extract-osx-sdk.sh
rm -rf 5.hfs MacOSX10.11.sdk
You may also need to symlink /System/Library/Frameworks/Security.framework to /path/to/MacOSX10.11.sdk/System/Library/Frameworks/Security.framework to have darwinssl be enabled during the build.
A build of clang+llvm is downloaded for Ubuntu 16.04 and extracted, a port of cctools compiled with gcc and installed alongside, and the dependencies are build using that toolchain.
cd ./depends
