| Bug report for Octave 2.0.9 configured for i586-pc-linux-gnu
| 
| Description:
| -----------
| 
| When compiling octave with:
| ./configure --prefix=/usr/local/ --enable-dl --enable-shared \
|    --enable-lite-kernel
| make
| make check
| 
| 1)The "check" utility may not be used before installation, because the
| dynamic libraries are not found.(all tests fails)

I believe this would be fixed by using libtool to handle building the
shared libraries.  Some time ago, someone volunteered to work on
converting Octave's Makefiles to use it, but I don't think the work
has been finished yet as I've not received any patches.

| 2) After making "make install" it was OK expect:
| 2a) I did (OK, it's stupid) run "make check" as root
|   => the test "geteuid-1.m" "getuid-1.m" "getegid-1.m" and "getgid-1.m"
|   did all fails (because my ID was "0"(=root))

These tests have already been fixed for the next release so that they
will succeed if the returned value is >= 0, not just > 0.

| 2b) The test "poly/poly-2.m" did fail
|   This test is:
| all (all (poly ([1, 2; 3, 4]) - [1, -5, -2] < 20 * eps))
| and should return 1, but on my machine:
|   poly ([1, 2; 3, 4]) - [1, -5, -2] 
| gives
|   0.0000e+00   0.0000e+00   2.4425e-15
| and  eps = 2.2204e-16
| Therefore, the test failed.

I changed this test to be

  all (all (abs (poly ([1, 2; 3, 4]) - [1, -5, -2]) < sqrt (eps)))

which I think should be good enough.

| One more remark: I first compiled "octave" without having DejaGnu installed,
| and couldn't run the "make check". Installing "DejaGnu" only did not allow
| me either to run it.

That's because configure checks for runtest.  Adding a definition for
RUNTEST in Makeconf should be enough to allow you to run `make check'
after installing dejagnu.

| Re-running "configure" just introduced errors.

Can you provide details?  I don't have any problems running configure
again after Octave has been compiled.

Thanks,
