This reverts commit 0585e053a8723fbdea4deefe17b6a6512274cde5.
Now that we autodetect any needed flags to enable C++11 support with the
AX_CXX_COMPILE_STDCXX macro, we no longer need to force this in
.travis.yml.
The xenial Travis-CI environment uses a g++ version that is old enough
that it doesn't use C++11 or newer by default, so we have to force it by
setting CXX to "g++ -std=c++11".
Per the protobuf developers,
We will from everything away from Google Code eventually. We haven't
decided where to put future release packages yet but as it seems github
supports this well chances are we'll use github as the canonical location
for all downloads.
This should fix the following build failure.
./protoc-c/protoc-c: error while loading shared libraries: libprotobuf.so.8: cannot open shared object file: No such file or directory
make: *** [t/test.pb-c.c] Error 127
It turns out that in YAML,
language: c
language: cpp
Actually means:
language: cpp
I'm not sure if travis-ci actually supports providing a list of values
for the 'language' parameter, but let's try it anyway.
The travis-ci environment is based on Ubuntu 12.04 LTS, which has an
older protobuf version (2.4.1). We need to depend on features that are
only available in 2.5.0 (and, later, 2.6.0), so instead of satisfying
the protobuf build dependencies from the Ubuntu repository, download and
install our own copy of protobuf.
The travis-ci build from this commit should succeed, since we are
compatible with protobuf 2.5.0.
Based on a patch from Ilya Lipnitskiy.
"As with the serial harness above, by default one status line is printed
per completed test, and a short summary after the suite has completed.
However, standard output and standard error of the test are redirected
to a per-test log file, so that parallel execution does not produce
intermingled output. The output from failed tests is collected in the
test-suite.log file. If the variable ‘VERBOSE’ is set, this file is
output after the summary."

Makefile.am: add valgrind to the AM_TESTS_ENVIRONMENT
configure.ac: enable valgrind testing option for ./configure
m4/valgrind-tests.m4: enable tracing children for libtool wrapper
script compatibility, but ignore standard binaries in /usr or /bin
the change that required protobuf >= 2.5.0 has been reverted, so there's
no need to build protobuf from source. use the system protobuf packages
instead.
also use distcheck to build and check the distribution. this will run
the test suite and perform various other checks. it will also perform a
VPATH build using the distribution tarball, which will catch any files
present in the git repository but inadvertently not distributed in the
tarball.
also test the build when configured with "--enable-rpc".
