A new binary release of the ELLCC cross compilation tool chain is available.
ELLCC is a pre-packaged set of tools designed to support cross compilation
for a variety of target processors.

This release supports MIPS and PowerPC 64 bit targets.

Unfortunately, I haven’t had time to debug build issues with the MinGW build. As a result the binaries of this release for this host are not available. If anyone is interested in looking into the build failure, patches welcome!

ELLCC includes:

• ecc (a clang/LLVM based C/C++ compiler)
• binutils
• GDB
• QEMU (on x86_64 Linux hosts)

The ELLCC run-time libraries are supplied pre-built for all targets and
are all covered with BSD-like licenses:

• libc++ The C++ standard library
• musl The POSIX compliant C library
• compiler-rt Low level compiler support
• expat XML parsing
• libedit Command history
• ncurses Terminal handling
• zlib Compression/decompression
• curl URL syntax data transfer
• libevent Event notification
• mbed TLS Transport Layer Security
• c-ares Asynchronous DNS
• libssh2 Client side SSH2
• libmetalink Metalink support
• openldap Lightweight directory access protocol
• nanomsg Several common communication patterns

ELLCC is entirely self hosting.

Binary tarballs are available from here.

The tool chain can build programs for ARM, Mips, PowerPC, and x86 Linux and
stand-alone targets and x86 Windows systems.

Pre-built binaries are available for ARM, Mips, and x86 Linux host systems
as well as x86_64 Windows and Mac OS X hosts.

All host systems can build programs for all the supported targets.

Available targets are listed here.
