Hi you all,<br><br>I am experiencing a strange behaviour when compiling ardour from source using gcc-4.3 on a i386 dual core machine running debian testing. Compile process stops at<br><br>g++ -o libs/surfaces/mackie/route_signal.os -c -Woverloaded-virtual -DGTK_NEW_TOOLTIP_API -DPACKAGE=\"ardour_mackie\" -DLIBSIGC_DISABLE_DEPRECATED -DDATA_DIR=\"/usr/local/share\" -DCONFIG_DIR=\"/usr/local/etc\" -DLOCALEDIR=\"/usr/local/share/locale\" -O3 -fomit-frame-pointer -ffast-math -fstrength-reduce -pipe -DARCH_X86 -mmmx -march=i686 -msse -mfpmath=sse -DUSE_XMMINTRIN -DBUILD_SSE_OPTIMIZATIONS -Wall -DHAVE_LIBLO -Ilibs -DENABLE_NLS -D_REENTRANT -D_LARGEFILE_SOURCE -D_LARGEFILE64_SOURCE -pthread -fPIC -Ilibs/pbd -I/usr/include/glib-2.0 -Ilibs/surfaces/control_protocol -Ilibs/libsndfile -Ilibs/midi++2 -Ilibs/ardour -Ilibs/sigc++2 -Ilibs/glibmm2 -I/usr/lib/glib-2.0/include -Ilibs/surfaces/mackie -I/usr/include/libxml2 -Ilibs/libsndfile/src libs/surfaces/mackie/route_signal.cc<br>

scons: *** [libs/surfaces/mackie/route_signal.os] Error 1<br>scons: building terminated because of errors.<br><br><br>Furthermore, the error does not occur when compiling on my amd64 dual core machine running debian testing too using gcc-4.3.<br>
<br>I googled around and it seems this problem could be related to <span id="thread_subject_site">fipa-* optimization options but didn't understand where fipa-* comes into play using scons...<br><br><br>Any suggestion?<br>
