* GCC-7 and glibc-2.27 compat code
* Statically link libstdc++ for GCC based builds
Makes sure binaries which are built on a newer build host still work
on older distros.
* Use python3 when installing MacOS native tools
* Move actual build logic out of Travis and upgrade to gcc-7
Travis will now simply call a few scripts which do the actual work.
These scripts will first create a "builder image" which contains the
necessary environment for the actual build. Then scripts are called
inside this builder image to do the build.
This should make us more independant from Travis and also allows us
to do local CI testing.
The build matrix is also moved out of .travis.yml and instead moved
into ci/matrix.sh. This script is sourced with only "BUILD_TARGET" being
set so that it internally can figure out which other environment
variables need to be set.
This commit also upgrades the used GCC version to 7. This is due to the
use of ubuntu:bionic as base image for the builder image.
* Add Jenkinsfiles for regular CI and nightly gitian builds
* Automatically download OSX SDK in gitian-build.sh
* Remove bogus "export MAKEJOBS=-j5"
* Forward cache/src dirs into builder container
Fixes caching issues on Travis.
* fix
* Fail build immediately when building depends took too long
* build: Enable C++11 build, require C++11 compiler
Implements #6211.
* depends: use c++11
* build: update ax_cxx_compile_stdcxx to serial 4
* build: force a c++ standard to be specified
Newer compilers may switch to newer standards by default. For example, gcc6
uses std=gnu++14 by default.
* c++11: fix libbdb build against libc++ in c++11 mode
atomic_init clashes with
* c++11: CAccountingEntry must be defined before use in a list
c++11ism. This fixes builds against libc++.
tl;dr: Update to the newer stable toolchain and SDK for OSX without giving up
any backwards compatibility. We can move to clang 3.5 as a next step which
allows use to use libc++ and the 10.10 sdk, but we'll need to find a build that
works in gitian/travis first.
Switch to a new, better maintained fork of cctools:
https://github.com/tpoechtrager/cctools-port
I've forked this and will be working on it some as well:
https://github.com/theuni/cctools-port
This brings in:
cctools v862
ld64: v241.9
It also fixes 64bit builds, so there's no longer any need to use a 32bit clang.
Since clang is no longer tied to an old/crusty 32bit build, clang has been
upgraded to 3.3. Unfortunately, there's a bug in 3.4 that breaks builds. 3.5
works fine, but there are no binary builds compatible with precise, which is
currently used for gitian and travis. We could always build our own if
necessary.
After updating to stable clang/linker/cctools, it's possible to use a more
recent SDK. The current SDK (10.7) through the most recent 10.10 have all been
built/tested successfully, both with and without 10.6 compatibility. However,
10.10 requires clang 3.5.
SDKs >= 10.9 use libc++ rather than libstdc++. This is verified working as well.
