Make distcheck started failing like this with this commit:
f31808989a
Silence subdir-objects warning from automake 1.14 (#781978)
However, also need to be referring to source files from a sibling
directory like this from tests/Makefile.am:
test_BlockSpecial_SOURCES = test_BlockSpecial.cc ../src/BlockSpecial.cc
^^^^^^^
First introduced by this commit:
c37be28148
Add unit tests for BlockSpecial constructors and internal caching (#781978)
This failure, if not exactly common, has been seen a number of times
before. Using this hint from a GNU Automake forum post:
converting to subdir-objects
http://gnu-automake.7480.n7.nabble.com/converting-to-subdir-objects-td21724.html
"I had the same issue and wouldn't care unless Automake 1.15 started
to warn about "source file in a subdirectory". In my case 'bar.o' is
also built from 'foo/Makefile' so I decided to skip using 'bar.c' as
SOURCE and instead link in 'foo/bar.o'.

Cheers,

"
Fix by avoiding referring to source files from a sibling directory when
building the unit test programs, instead refer to object files instead.
Note that the automake subdir-objects option is still required to
silence the warning because of the use of source files in subdirectories
by lib/gtest/Makefile.am.
Bug 785308 - make distcheck fails with *.Po: No such file or directory
On CentOS 6, with glib/glibmm 2.28, running the tests fails thus:
$ ./test_PipeCapture
Running main() from gtest_main.cc
[==========] Running 4 tests from 1 test case.
[----------] Global test environment set-up.
[----------] 4 tests from PipeCaptureTest
[ RUN ] PipeCaptureTest.EmptyPipe
GLib-ERROR **: The thread system is not yet initialized.
aborting...
Aborted (core dumped)
For glib before version 2.32, the threading system must be explicitly
initialised with a call to g_thread_init(), or the Glibmm
Glib::thread_init() equivalent to prevent this error.
Deprecated thread API, g_thread_init()
https://developer.gnome.org/glib/stable/glib-Deprecated-Thread-APIs.html#g-thread-init
Do this by providing our own main() which also initialises the Glib
threading system, rather using and linking in the Google Test provided
main().
Bug 777973 - Segmentation fault on bad disk
So far just tests sending 0 bytes and a few ASCII bytes into a pipe and
that they are read correctly by the PipeCapture class.
Bug 777973 - Segmentation fault on bad disk
So far only includes tests of the construction of BlockSpecial objects
and the interaction with the internal cache used to reduce the number of
stat(2) calls. Tests have been designed to be runable by non-root users
and assume as little as possible about the environment by discovering
used block device names and symbolic link name.

Running 'make distcheck' fails like this:

make: *** [distcheck] Error 1
What is happening is that distcheck [1] performs a VPATH build which
uses separate read-only source and read-write build trees. Shipped
source files, such as .h and .cc, are located in the source tree and the
built files, such as .o and .la, are compiled into the build tree. In
this case the absolute path to libgtest_main.la is specified using
$(top_srcdir) for the source tree, rather than $(top_builddir) for the
build tree, hence the cannot find file type error. This error doesn't
occur when just performing a 'make check' because that builds in the
source tree so $(top_builddir) is the same as $(top_srcdir).
Fix by correctly specifying the absolute path to the libgtest*.la files
using $(top_builddir).

https://www.gnu.org/software/automake/manual/automake.html#Checking-the-Distribution
Note that for VPATH builds the Automake Manual [2] also recommends using
a pair of -I options to specify header files are found in both the build
and source trees, something like:
AM_CPPFLAGS = -I$(top_builddir)/some/subdir -I$(top_srcdir)/some/subdir
This is unnecessary for GParted as all header files are shipped as part
of the source archive and no header files are created as part of the
build process. Therefore adding -I options specifying $(top_builddir)
include directories would just be specifying empty or non-existent
include directories in the build tree.

Bug 781978 - Add Google Test C++ test framework
Now 'make check' will additionally build and run the test suites in the
./tests directory. Add initial always successful dummy test suite.
This is done using Automake support for testing.

./tests/Makefile.am takes some influence from the same file in the
