Thanks, ĸen, just learning that. It is different from what I thought.

Leaving this to consider later, if everything fails. Have followed other

I tried it before, and again today. Does not work so simply. First,
tried with Arch's tar ball for ffmpeg-compat. Then, just used
ffmpeg-0.8.7, but with their instructions to make it -compat. Build
succeeded, audacity works, but with a dirty trick. For ffmeg-compat-0.8.7:
./configure \
--prefix=/usr \
--incdir=/usr/include/ffmpeg-compat \
--libdir=/usr/lib/ffmpeg-compat \
--shlibdir=/usr/lib/ffmpeg-compat \
...
Then, DESTDIR install, remove $DESTDIR/usr/{bin,share}, copy to /usr.
And it works fine, just used it with previous audacity that was removed
(now) from /usr/local and new one at /usr.
Audacity build with instructions a la Arch fails at make, complaining
that cannot find gtk/gtk.h:
CaptureEvents.cpp:34:21: fatal error: gtk/gtk.h: Arquivo ou diretório
não encontrado
compilation terminated.
make[1]: ** [CaptureEvents.o] Erro 1
...
But it is in the system:
$ find /usr -name gtk.h 2>/dev/null
/usr/include/gtk-3.0/gtk/gtk.h
/usr/include/gtk-2.0/gtk/gtk.h <----------- must be this one
/usr/src/linux-3.10.1-NG-pae/tools/perf/ui/gtk/gtk.h
/usr/src/linux-3.10.2-NG-pae/tools/perf/ui/gtk/gtk.h
I really do not understand how to tell make where they are, using
CPPFLAGS and/or LDFLAGS, tried many wrong combinations. Also tried to
instruct with PKG_CONFIG_PATH as done for configure.
PKG_CONFIG_PATH+="/usr/lib/ffmpeg-compat/pkgconfig" make
Finally, the dirty trick, please find attached the complete g++
instruction, as it would be broken by the mail client:
PKG_CONFIG_PATH+="/usr/lib/ffmpeg-compat/pkgconfig" \
./configure --prefix=/usr
make
cd src &&
g++ -c -s `pkg-config gtk+-2.0 --cflags` `pkg-config gtk+-2.0 --libs` \
-I../lib-src/portmixer/include ........... \
CaptureEvents.cpp -o CaptureEvents.o &&
cd .. &&
make
make install
...
With "-s `pkg-config gtk+-2.0 --cflags` `pkg-config gtk+-2.0 --libs`"
included, it succeeds compiling CaptureEvents.
I do not think anyone would consider this an acceptable solution, but I
do not know how to tell make to do it properly.
If possible to be done properly by modifying some flags for make, please
educate me.
Thanks in advance.
