Ok, firstly running file and ldd on the Curses program example in my last email: [EMAIL PROTECTED] 07-pinvoke $ file -k /lib64/libncurses.so.5.4 /lib64/libncurses.so.5.4: ELF 64-bit LSB shared object, AMD x86-64, version 1 (SYSV), stripped
[EMAIL PROTECTED] 07-pinvoke $ file -k Curses.exe
Curses.exe: MS Windows PE 32-bit Intel 80386 console executable\012-
MS-DOS executable (EXE), OS/2 or MS Windows
[EMAIL PROTECTED] 07-pinvoke $ file /usr/local/bin/mono
/usr/local/bin/mono: ELF 64-bit LSB executable, AMD x86-64, version 1
(SYSV), for GNU/Linux 2.4.1, dynamically linked (uses shared libs), not
stripped
Now for the actual libraries I am trying to use in my real program:
[EMAIL PROTECTED] 07-pinvoke $ file -k /usr/local/lib/libhighgui-0.9.so.5.0.0
/usr/local/lib/libhighgui-0.9.so.5.0.0: ELF 64-bit LSB shared object,
AMD x86-64, version 1 (SYSV), not stripped
[EMAIL PROTECTED] 07-pinvoke $ file -k /usr/local/lib/libopencv-0.9.so.5.0.0
/usr/local/lib/libopencv-0.9.so.5.0.0: ELF 64-bit LSB shared object, AMD
x86-64, version 1 (SYSV), not stripped
(this is a C program which uses the above libraries just fine)
[EMAIL PROTECTED] objRec $ file -k objectRecognition
objectRecognition: ELF 64-bit LSB executable, AMD x86-64, version 1
(SYSV), for GNU/Linux 2.4.0, dynamically linked (uses shared libs), not
stripped
Finally, you should try running mono with MONO_LOG_LEVEL=info and
> MONO_lOG_MASK=dll.
When I try to run the curses example with logging on I get the following:
Mono-INFO: DllImport loading: 'libncurses'.
Mono-INFO: DllImport error loading library '/usr/lib/libncurses.so:
invalid ELF header'.
(Curses.exe:10129): Mono-WARNING **: DllImport unable to load library
'/usr/lib/libncurses.so: invalid ELF header'.
And with my open computer vision program:
Mono-INFO: DllImport loading: 'libopencv'.
Mono-INFO: DllImport error loading library '/usr/local/lib/libopencv.so:
undefined symbol: __gxx_personality_v0'.
(CvImage.exe:16545): Mono-WARNING **: DllImport unable to load library
'/usr/local/lib/libopencv.so: undefined symbol: __gxx_personality_v0'.
So, it looks like mono finds the libncurses library, but can't load it
for some reason, like wise with the opencv library. The error message is
a bit miss leading in this case. I still don't know how to fix the
problem though.

Ok this is strange...I wonder what is different between your environment
and mine that it doesn't work on mine?
