I have been unable to get Cygwin Octave to run:

vanzandt:~ $ octave
vanzandt:~ $

Here's my version info:

vanzandt:~ $ cygcheck -c -h cygwin
Cygwin Package Information
Package              Version        Status
cygwin               1.5.25-15      OK
vanzandt:~ $ cygcheck -c -h octave
Cygwin Package Information
Package              Version        Status
octave               3.0.3-1        OK

I see Octave 3.2 has been packaged for Cygwin 1.7, but apparently Cygwin 1.=
7 hasn't been released.  I have certainly taken no special steps to get a p=
rerelease version.  Octave is the only Cygwin program I've noticed problems=
 with, so I'm reluctant to go to a prelease version of Cygwin.=20=20

Apparently octave cannot find two shared libraries:

vanzandt:~ $ which octave
/bin/octave
vanzandt:~ $ file /bin/octave
/bin/octave: symbolic link to `octave-3.0.3.exe'
vanzandt:~ $ cygcheck /bin/octave-3.0.3.exe
C:\cygwin\bin/octave-3.0.3.exe
  C:\cygwin\bin\cygoctinterp.dll
    C:\cygwin\bin\cygcruft.dll
Error: could not find cygblas.dll
      C:\cygwin\bin\cygwin1.dll
        C:\WINDOWS\system32\ADVAPI32.DLL

            C:\WINDOWS\system32\ntdll.dll
          C:\WINDOWS\system32\RPCRT4.dll
            C:\WINDOWS\system32\Secur32.dll

      C:\cygwin\bin\cyggcc_s.dll
    C:\cygwin\bin\cygoctave.dll
Error: could not find cygblas.dll
      C:\cygwin\bin\cygfftw3-3.dll
Error: could not find cyglapack.dll
      C:\cygwin\bin\cygreadline6.dll
        C:\cygwin\bin\cygncurses-9.dll
        C:\WINDOWS\system32\USER32.dll
          C:\WINDOWS\system32\GDI32.dll
    C:\cygwin\bin\cyghdf5-0.dll
      C:\cygwin\bin\cygz.dll
      C:\cygwin\bin\cyggcc_s-1.dll

Those libraries actually are installed, as part of the lapack package:

vanzandt:~ $ cygcheck -c lapack
Cygwin Package Information
Package              Version        Status
lapack               3.0-8          OK
vanzandt:~ $ cygcheck -l lapack|grep cyglapack
/usr/lib/lapack/cyglapack.dll
vanzandt:~ $ ls -l /usr/lib/lapack/cyg*
-rwxr-x---+ 1 jrv Users  591360 Mar 24  2006 /usr/lib/lapack/cygblas.dll
-rwxr-x---+ 1 jrv Users 5003776 Mar 24  2006 /usr/lib/lapack/cyglapack.dll

I believe Cygwin is supposed to automatically ensure that the correct versi=
on of each shared library is installed and loaded, but it looks like some p=
art of that has broken down.=20=20

Do I have the right version of lapack installed?  (setup.exe also offers 3.=
0-5)  Is there a manual way of getting the loader to look in /usr/lib/lapac=
k?  E.g. is there a Cygwin equivalent to the Linux program ldconfig?  I tri=
ed setting LD_LIBRARY_PATH, and also installing symlinks from /c/Cygwin/bin=
 like this:

vanzandt:/c/cygwin/bin $ ls -l cygla*
lrwxrwxrwx 1 jrv Domain Users 29 Jul 13 10:13 cyglapack.dll -> /usr/lib/lap=
ack/cyglapack.dll

I'd appreciate any suggestions.

Hi Jim,
for generic cygwin issue the cygwin at cygwin dot com is the
usual mailing list to report problem and ask for support.

If octave don't start is a clear symptom of a missing library

try=20
$ cygcheck octave


you should have=20
$ cygcheck octave
Found: C:\cygwin2\bin\octave.exe
 -> C:\cygwin2\bin\octave-3.2.0.exe
C:\cygwin2\bin\octave-3.2.0.exe

otherwise missing libraries will be reported.
Please also note that=20
octave-3.2 has been built for cygwin-1.7, so
I assume you have a cygwin-1.7 installation in place.

If you check on the mailing list archive,=20
http://cygwin.com/ml/cygwin/

You will see that incomplete cygwin installation=20
is not an unusual problem.

Is octave the only application not working=20
for you ?

Regards
Marco
