Texttools (Linux) - problem during compilation

["xaerxess@gmail.com" <xaerxess@gmail.com>]

Hi,

 I want to use texttools ( http://www.pegasoft.ca/tt.html ) in my
program and first I checked how to compile an example file. I installed
libtexttools-dev via apt-get and then tried to compile the file:

$ gnatmake -aI/usr/share/ada/adainclude/texttools
-aO/usr/lib/ada/adalib/texttools basic2.adb -largs -ltexttools
gnatbind -aO./ -aO/usr/lib/ada/adalib/texttools -I- -x basic2.ali
gnatlink -ltexttools basic2.ali
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__interrupts__install_handlers'
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__interrupts__register_interrupt_handler'
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__interrupts___init_proc__7'
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__tasking__protected_objects__entries__initialize_protection_entries'
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__tasking__protected_objects__entries__unlock_entries'
/usr/bin/../lib/libtexttools.so: undefined reference to
`system__tasking__protected_objects__entries__lock_entries'
gnatlink: cannot call /usr/bin/gnatgcc
gnatmake: *** link failed.

What's wrong? Of course, there is a link gnatgcc in /usr/bin/

BTW: Has anybody any experience with using texttools?
