[Discuss-gnuradio] cvs compile error (libtool: compile: specify a tag with `--tag')
Hey people, I wonder if anyone can point me in the right direction.I started gentoo linux about 4 weeks ago so please excuse my noobiness. Grabbing the files from cvs is fine. After doing a "./for-all-dirs ../buildit" the following error stops the rest of the compile. make all-am make[5]: Entering directory `/home/mj/cvs/gnuradio/gr-build/gnuradio-core/src/lib/filter' /bin/sh ../../../libtool --mode=compile as @ASFLAGS@ -c -o float_dotprod_sse.lo `test -f float_dotprod_sse.s || echo './'`float_dotprod_sse.s libtool: compile: unable to infer tagged configuration libtool: compile: specify a tag with `--tag' make[5]: *** [float_dotprod_sse.lo] Error 1 i've tried lots of random things mentioned in the gentoo forums such as emerge --oneshot libtool etc with no luck. here's my "emerge --info" if this helps: Portage 2.0.51-r15 (default-linux/x86/2004.3, gcc-3.3.5, glibc-2.3.4.20040808-r1, 2.6.10-gentoo-r6 i686) = System uname: 2.6.10-gentoo-r6 i686 Intel(R) Pentium(R) M processor 1600MHz Gentoo Base System version 1.6.8 Python: dev-lang/python-2.3.4 [2.3.4 (#1, Oct 24 2004, 07:40:35)] ccache version 2.3 [enabled] dev-lang/python: 2.3.4 sys-devel/autoconf: 2.59-r6 sys-devel/automake: 1.5, 1.9.4 sys-devel/binutils: 2.15.92.0.2-r1 sys-devel/libtool: 1.5.10-r4 virtual/os-headers: 2.4.21-r1 ACCEPT_KEYWORDS="x86" AUTOCLEAN="yes" CFLAGS="-O3 -march=pentium3 -fomit-frame-pointer -ftracer -momit-leaf-frame-pointer -pipe" CHOST="i686-pc-linux-gnu" CONFIG_PROTECT="/etc /usr/X11R6/lib/X11/xkb /usr/kde/2/share/config /usr/kde/3.3/env /usr/kde/3.3/share/config /usr/kde/3.3/shutdown /usr/kde/3/share/config /usr/share/config /var/qmail/control" CONFIG_PROTECT_MASK="/etc/gconf /etc/terminfo /etc/env.d" CXXFLAGS="-O3 -march=pentium3 -fomit-frame-pointer -ftracer -momit-leaf-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FEATURES="autoaddcvs autoconfig ccache distlocks sandbox sfperms" GENTOO_MIRRORS="http://distfiles.gentoo.org http://distro.ibiblio.org/pub/Linux/distributions/gentoo"; MAKEOPTS="-j2" PKGDIR="/usr/portage/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="x86 X alsa apache2 apm arts avi berkdb bitmap-fonts crypt cups encode f77 fam flac font-server foomaticdb fortran gdbm gif gpm gtk gtk2 imlib ipv6 java jpeg junit kde libg++ libwww mad mikmod motif mpeg mysql ncurses nls oggvorbis opengl oss pam pdflib perl png python qt quicktime readline samba sdl spell ssl svga tcpd tiff truetype truetype-fonts type1-fonts xml2 xmms xv zlib" Unset: ASFLAGS, CBUILD, CTARGET, LANG, LC_ALL, LDFLAGS, PORTDIR_OVERLAY Any help would be greatly appreciated :) cheers, mj - m0mik hotstudent.com [are you hot enough?!] __ Do you Yahoo!?

After changing: LTASCOMPILE = $(LIBTOOL) --mode=compile $(AS) $(AM_ASFLAGS) $(ASFLAGS) to LTASCOMPILE = $(LIBTOOL) --mode=compile $(CCAS) $(CCASFLAGS) $(AS) $(ASFLAGS) and then running "./for-all-dirs ../buildit" it still gives the same error.

The file I used to grab the Radio2 signal (89.8Mhz) with was ursp_rx_cfile.py (no 5.75Mhz IF mentioned) with decim=200, dcc-freq=31.3e6. The wfm_rcv_file.py was used to recover the audio from the generated dat file easily. Now, with wfm_rcv.py working and set to the same settings as usrp_rx_cfile.py I cannot recover the audio. I can still see the waveform in usrp_fft.py so it is still there. Am i missing something obvious? Also, the max ddc for usrp_fft.py is 32e6 so i'm assuming the maximum usrp rf frequency is 32Mhz??? and the Radio2 wfm reception i'm receiving is some harmonic.

[Discuss-gnuradio] rf to data file - usrp_rx_file.py
Hey guys, I have been trying to find a way to use usrp_rx_file.py to grab a certain bandwidth and sample rate from my usrp and save it into a file. By moving the decimation value to max i can't get the bandwidth down to 12.5khz. How could I add a bandpass filter to usrp_rx_file.py? Is this even the right way to go? Also, is it possible to transmit the captured rf from the file at a later date?
