fine thanks.


The last commad is this one:
> /bin/bash ../libtool --tag=CC   --mode=link gcc -g -O2 -pthread
>   -DHAVE_CONFIG_H  -Wall -W -Wshadow -Wformat -Wpointer-arith

but lm is reported so I have no clue.
-no-undefined is need on windows but should make no difference on Linux,
nor should make any difference the order of the linking libraries

For your info, this is libtool echo of the last command:

> libtool: link: gcc -g -O2 -pthread -DHAVE_CONFIG_H -Wall -W -Wshadow
> -Wformat -Wpointer-arith -Wmissing-prototypes -Wstrict-prototypes
> -Wwrite-strings -Wcast-align -Wcast-qual -g -O2 -pthread -pthread -g -O2
> -pthread -o .libs/octave main.o  ./.libs/liboctinterp.so
> ../liboctave/.libs/liboctave.so ../libcruft/.libs/libcruft.so -lm
> -pthread -Wl,-rpath -Wl,/usr/local/lib/octave/3.6.4

and, of course, this is the linking error:

> ../libcruft/.libs/libcruft.so: undefined reference to `c_exp'

and here Make advises you that a command is failed in that directory
