Re: Problems getting dependencies compiled before executable....

[Santosh]

For files in same directory, it does compile according to 
dependencies order. But for directories, it follows the order you give.
Why does it not do automatically according to dependency, 
I do not know. I think it is good if you have the dependencies between
modules clearly with you while designing and use it to give the order
to automake.

with regards,
Santosh.
