[ardour-dev] scons issues

[Patrick Shirkey]

Hi,

First I am using binutils-2.17 because the older versions caused serious 
issues with kernel upgrades for my system. However the errors I am 
seeing are not specifically referenced anywhere I can find so I am 
asking here for good measure.

=======

1: Does the version of flac make any difference to the build?

I have 1.1.2.

libsndfile can find it and reference the symbol

`FLAC__seekable_stream_encoder_set_tell_callback`

but the ardour build fails to see it :/


- I have installed libsndfile-1.0.17 in --prefix=/usr/


========


2: I have exported LD_LIBRARY_PATH to make sure.

LD_LIBRARY_PATH="/usr/lib:/usr/local/lib:/usr/X11R6/lib:/usr/src/mysql/lib:/usr/local/ssl/lib"


=======

3: I get this error message with a fresh tarball:

scons: Reading SConscript files ...
Checking for usb_interrupt_write() in C library usb... (cached) yes
Checking for FLAC__stream_decoder_new() in C++ library FLAC... (cached) no
Checking for C++ header file boost/shared_ptr.hpp... (cached) no
Boost header files do not appear to be installed.

- The boost headers are installed in /usr/include/boost/

=======

4: To get past that I have disabled the exit after the boost check in 
the SConstruct file, line #486.

Then everything goes well until:

- Strangely enough I also upgraded to libsamplerate-0.1.2 into 
/usr/local/ and after that the build system found it and recompiled the 
appropriate ardour lib without any issues.



Any furthur ideas?



Cheers.
