[LTP] [RFC PATCH v2 0/5] Travis enhancements

[LTP] [RFC PATCH v2 0/5] Travis enhancements

[Petr Vorel]

TL;DR
See https://travis-ci.org/pevik-travis/ltp/builds/310089523

Now we have 11 jobs testing 7 compilers in 3 different ways (mostly normal
builds, 2x 32-bit cross-compile builds, 1x out-of-tree build, 1x build with
minimal dependencies).

It seems to be rule running only 5 containers at a time, so 11th build slowes
building about 4 min (18 min vs. 22 min). Which build would you remove?

I decided to specify dependencies in file (saves some duplicity).
These files can be used for builds on Debian/Ubuntu (as we re

Changes v1->v2:
* Dropped compilers:
  Dropped: gcc 4.6, 4.7, 4.8 and clang 3.5, 3.8
* Added different types of builds (32-bit cross-compile builds, out-of-tree build)
* Better handling of header and library dependencies (minimal build and build with full support).
* Minor changes.

Notes what I learned:
* Travis needs sudo for using apt, but it does not allow to use it in script
  (it must be in travis.yml)
* Don't use $INSTALL environment variable (I haven't figured how, but it
  reported build to be failed).


Petr Vorel (5):
  travis: Add build script and use it in travis
  travis: Drop old compilers, add new ones
  travis: Add 32-bit cross-compile builds
  travis: Add out-of-tree build
  travis: Install all dependencies + add build with minimal dependencies

[LTP] [RFC PATCH v2 1/5] travis: Add build script and use it in travis

[Petr Vorel]

This script handles native build, 32-bit cross-compile build and
out-of-tree build.

Script is for travis build, but can be used for local builds as well.

For usage run
./build.sh -h

[LTP] [RFC PATCH v2 5/5] travis: Install all dependencies + add build with minimal dependencies

[Petr Vorel]

Currently travis has installed toolchain with libraries, glibc and
kernel headers so some of the packages listed are already installed.

Install all dependencies (headers and libraries).
The only exception is selinux support on 32bit build as as
libsepol1-dev:i386 conflict with libsepol1-dev for amd64, thus both
cannot be installed.

During reinstallation for build with minimal dependencies we need to
filter out some packages as toolchain package depends on it.

For minimal build chosen gcc 6 (relativelly recent gcc version, but not
too new).

Here you set --prefix to current ltp path, why not "/opt/ltp"?

And, I get some installing errors with this configuration for build in tree.

Permissions (using containers => no sudo). We could have sudo, but it would be without
containers (=slow).
See

Github clones into different directory:
git clone --depth=50 --branch=master https://github.com/linux-test-project/ltp.git linux-test-project/ltp
OK, you're building in the same directory as the prefix is set. I'll fix it so we can use
it for local builds as well.
BTW: I was thinking before using /tmp, but as whole directory has ~600MB, I'll use
different name under $HOME).

Thanks for reporting it!


Kind regards,
Petr

Well we do the build without any additional libs with gcc-7, we may as
well switch it to clang-3.9 and drop the build with clang-3.9 with the
additional libraries, that way we wouldn't lost much coverage.

gcc-7 is used for out-of-tree (gcc-6 was used in v3 for build with minimal dependencies)
OK clang-3.9 is now used only for build with minimal dependencies and it's the only build
of this type.
https://travis-ci.org/pevik-travis/ltp/builds/312014219

BTW: I'm planning to add also arm32 cross-compile build in near future. To keep only 10
jobs, I'll replace gcc-6 normal with all dependencies by it.
