Hello everyone.

I took me a while to realise I did not mentionned that I was not
subscribed to the list. So I just got your reply to my initial
mail. I'll go over this mail and then expose my attempt to port
ecasound-1.8.5d15 to FreeBSD 4.2-stable.

If you give me a hand, I'll stick with you and make it work out
completely for FBSD.

Not really. It was more something like "I don't like a text interface
for sound manipulations" type of thing. :) The interface in itself
seems to be very good, on the contrary.

Well, in fact, there *would* be something. I (as a new/dumb user) am
disoriented by the usage message displayed when starting ecasound as
just "ecasound". I think it should go interactive right there, with an
help message. I could also be nice to have some kind of reference
there on all the commands documented in the man pages. Even if it's
just a small listing.

However:

cs-edit this:
-b:1024 -sr:44100 -n:test -i:/dev/dsp
-o:/tmp/test.mp3

-a:default

(eca-chainsetup) Setting buffersize to (samples) 1024.
(eca-chainsetup) Setting internal sample rate to: 44100
(eca-chainsetup) Setting chainsetup name to "test".
(eca-controller) Selected chainsetup: "test".
(eca-controller) Loaded chainsetup from file "/var/tmp/tmp.0.M47429.ecs".
ecasound ('h' for help)> -i:/dev/audio
Segmentation fault (core dumped)

Yay. Examining:

(gdb) bt

#8 0x804b2f9 in _start ()

I would have to recompile with debugging symbols, but only if you tell
me it's worth it (and how to do it, d$/&*$mn libtool :).

Trying with ecawave 0.3.3d3.

$ # but not here!

I don't know why "-lecasound" is not in there itself... But looking at
other libs, I don't think this is really a problem. It should link
just fine. And anyways, doesn't ecasound need this to run _at all_??

FBSD has a nice tendency of being paranoïd on that matter. :)

As a side note, I am now try to port ecasound-1.8.5d15 to FreeBSD
4.2-stable.

$ ./configure --enable-sys-readline --prefix=/u/an_temp

(I also tried with --with-gnu-ld)

Problem 1:

In the file libecasound/eca-object-map.cpp:23 , the #include <regex.h>
directive is used without the necessary #include <sys/types.h>. (man
regex(3): http://www.freebsd.org/cgi/man.cgi?regex).

Problem 2 (linking, again):

This time I really can't tell. I don't know libtool at all and it
gives me headaches. The error is:

      /usr/libexec/elf/ld: cannot find -lecasound

,again. :)

Curiously, there *could* be no way of locating ecasound now since no
ldconfig has been made and its path is not specified on the command
line.

However, please note that I have *not* removed the ecasound-1.8.2r14
libraries that were successfully installed ('was hard enough.. :).

That about the farther I can go for now...

[The end of the compilation output:

Thanks for any help. Please to forget to CC: me personnally as I am
not on the list...
