Binary Toolchain Requirements
This page contains what michaelh1 thinks the requirements for a binary toolchain build are. I've put question marks on areas that need to be comfirmed or checked.
Provide an up-to-date, validated binary build of the current Linaro Toolchain outputs that run on Linux and Windows and can be used to build programs for the LEB.
- C and C++
- Binutils with ld and gold
- May include Fortran and Java
- Turns on all new features to match Ubuntu's style (gold, build IDs, etc)
- Sysroot comes from the current LEB release (currently Maverick)
- ABI compatible with the LEB
- Tuned for Cortex-A9
- Compatible with Cortex-A8, i.e. enables the errata workarounds
- NEON FPU (VFPv3D16 instead?)
- Compatible with the LEB runtime libraries which are libgcc, libstdc++, ...?
- Windows and generic Linux
- Native application, no compatibility layer
- Supported on all current Windows versions with the latest service pack
- Windows XP Pro SP3
- Windows Vista Business SP2
- Windows 7 Pro
- Windows 8 Pro
- Supported on the four most popular Linux distributions
- Supported on the latest release for all
- Supported on the LTS equivalent for all
- Ubuntu 11.04 and later
- Fedora 14 and later
- Debian 6.0.?
- openSUSE 11.4?
- Supported on 32 bit and 64 bit installations
- If a 32 bit build, must have the same capabilities as the corresponding 64 bit build
- Appropriate for use under:
- Windows NT CMD prompt
- Eclipse Helios CDT 3.6.2
- Allow community patches for others such as MacOS, FreeBSD
- Build scripts may be Linux hosted. The Windows build does not have to be buildable on Windows.
- Linux tarball
- Windows zip file
- Windows installer?
- Documentation such that an entry level engineer can install and exercise
- Scripts to reproduce the binary
- Instructions to reproduce
- Instructions on basic customisation
- Run the GCC testsuite with real board as target
- Run the GCC testsuite with QEMU as target
- No unavoidable regressions compared to a native testsuite run
- May run these under Cygwin
- Exercise by building other libraries:
- Python, providing its dependencies are small
- Test on a Windows 32 bit host
- Test on a Ubuntu 11.? ?? bit host
- Have a landing page?
- Provide installation documentation
- Provide release notes documenting what is in a particular build
- Support via linaro-toolchain
- Support via Launchpad bugs
- The Bug URL and similar shall point to the right place
- Support is the same as the source release, i.e.:
- No long-term branches
- Bugs are fixed in the latest release only
- Sysroot is updated six monthly when the next release comes out
- Triage and response times as per the toolchain Flyer
- Via Launchpad
- Stable releases every 4 months
- Build daily snapshots from Jenkins/Cbuildv2.
- Available within 1 week of source release. Preferably available on the same day.
- Non-Cortex-A builds
