Dear Mr. Eaton,

the problem is that I have several libqrupdate on my system,
a
 /usr/lib64/libqrupdate.so.1.1 installed by yum

and a
 /usr/local/lib/libqrupdate.so.1.0
 /usr/local/lib/libqrupdate.a
                               installed with make install

now I removed the libqrupdate.so.1.0 and everything works.

Does configure make checks with the 1.1 version and make uses the other version?

Thank you for your help
Ciau Erich

Looking at liboctave/dbleLU.cc, it seems that dlu1up should only be referenced if HAVE_QRUPDATE_LUU is defined.

The configure test for this feature appears to work correctly on my system, which also lacks this function in libqrupdate.

Why does the test fail to work properly on your system?

To start debugging this, check the config.log file on your system and look for the test for slu1up.  There is no test for dlu1up, since it is expected that either both of these functions will be defined, or neither will.  Also, what is the output of


nm /usr/lib/libqrupdate.a | grep lu1up


on your system?

I did:

hg pull
hg update
hg log -l 1
Ă„nderung:        11333:492e7b587352
make -j2
make check



../run-octave --norc --silent --no-history ./fntests.m .

Integrated test scripts:
