# "native" may be used in place of "*-*-*".

Configuring the dejagnu harness to work with libstdc++-v3 in a cross
|
||||
compilation environment has been maddening. However, it does work now,
|
||||
and on a variety of platforms. Including solaris, linux, and cygwin.
|
||||
|
||||
To debug the test harness during runs, try invoking with
|
||||
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v"
|
||||
or
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="-v -v"
|
||||
|
||||
There are two ways to run on a simulator: set up DEJAGNU to point to a
|
||||
specially crafted site.exp, or pass down --target_board flags.
|
||||
|
||||
Example flags to pass down for various embedded builds are as follows:
|
||||
|
||||
--target=powerpc-eabism (libgloss/sim)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=powerpc-sim"
|
||||
|
||||
--target=calmrisc32 (libgloss/sid)
|
||||
make check-target-libstdc++-v3 RUNTESTFLAGS="--target_board=calmrisc32-sid"
|
||||
|
||||
--target=xscale-elf (newlib/sim)

Current testing problems with cygwin-hosted tools:
|
||||
|
||||
There are two known problems which I have not addressed. The first is
|
||||
that when testing cygwin hosted tools from the unix build dir, it does
|
||||
the wrong thing building the wrapper program (testglue.c) because host
|
||||
and target are the same in site.exp (host and target are the same from
|
||||
the perspective of the target libraries)
|
||||
|
||||
Problem number two is a little more annoying. In order for me to make
|
||||
v3 testing work on Windows, I had to tell dejagnu to copy over the
|
||||
debug_assert.h file to the remote host and then set the includes to
|
||||
-I./. This is how all the other tests like this are done so I didn't
|
||||
think much of it. However, this had some unfortunate results due to
|
||||
gcc having a testcase called "limits" and C++ having an include file
|
||||
called "limits". The gcc "limits" binary was in the temporary dir
|
||||
when the v3 tests were being built. As a result, the gcc "limits"
|
||||
binary was being #included rather than the intended one. The only way
|
||||
to fix this is to go through the testsuites and make sure binaries are
|
||||
deleted on the remote host when testing is done with them. That is a
|
||||
lot more work than I want to do so I worked around it by cleaning out
|
||||
D:\kermit on compsognathus and rerunning tests.
