gnu make - automake-ing in bison which works fine with handwritten makefile -

-

friends,

i trying create makefile via gnu-autotools flex+bison+c code (toy code, ma say). handwritten makefile works fine 

cc=gcc #-g -wall flex=flex bison=bison libs=lfl prog=parse  ${prog}:bib.y scan.l main.c     ${bison} -d bib.y     ${flex} -i scan.l     ${cc} -wall main.c lex.yy.c bib.tab.c `pkg-config --cflags --libs gtk+-3.0 glib-2.0` -${libs} -o $@  clean:     rm -f lex.yy.c bib.tab.h ${prog} bib.tab.c      touch scan.l bib.y main.c

only giving warnings unused variables:

$ make -f makefile  bison -d bib.y flex -i scan.l gcc  -wall main.c lex.yy.c bib.tab.c `pkg-config --cflags --libs gtk+-3.0 glib-2.0` -lfl -o parse main.c: in function ‘main’: main.c:35:8: warning: type defaults ‘int’ in declaration of ‘yy_create_buffer’ [-wimplicit-int] main.c:35:8: warning: unused variable ‘yy_create_buffer’ [-wunused-variable] lex.yy.c:1120:17: warning: ‘yyunput’ defined not used [-wunused-function] lex.yy.c:1161:16: warning: ‘input’ defined not used [-wunused-function] bib.y: in function ‘parse_entry’: bib.y:79:9: warning: unused variable ‘author’ [-wunused-variable]

but then, when tried create via autotools, giving problem:

##configure.ac (made autoscan) ac_prereq([2.69]) ac_init([bi-try],[1.0],[rudra.banerjee@aol.co.uk]) am_init_automake([1.9.6])  # checks programs. ac_prog_cc ac_prog_yacc ac_prog_lex  # checks libraries. #ac_prog_libtool # checks header files.  # checks library functions. am_path_gtk_3_0([3.4.0],,ac_msg_error([gtk+ 3.0.0 or higher required.]))  ac_config_files([makefile]) ac_output

and makefile.am

bin_programs = bitry bitry_sources = bib.y scan.l main.c  am_yflags = -d am_lflags = -i  bitry_ldadd = @gtk_libs@ @lexlib@ am_cflags = @gtk_cflags@

the output of process is:

$ autoreconf --install makefile.am: installing './install' makefile.am: installing './copying' using gnu general public license v3 file makefile.am: consider adding copying file version control system makefile.am: code, avoid questions license project uses

i posted long output of makefile might helpful experienced eyes. looking forward help.

ah...solved. bison -d foo.y makes foo.tab.h ;

for automake, making foo.h.

solved

How to calculate SNR of signals in MATLAB? -

-
i've encountered simple, yet fundamental problem on calculating snr: there several signals : s1 = original , pure clean signal without noise. n1 = white gaussian noise going added s1. s2 = s1 + n1 (the noisy signal before performing noise-reduction algorithm) s3 = noise-reduced signal (after performing noise reduction algorithm) n2 = s3 - s1 (the amount of noise after performing noise-reduction algorithm) now want compare snr before , after performing noise-reduction algorithm. which signals should consider snr_before!? s1/n1 or s2/n1 ? which signals should consider snr_after!? s3/n1 or s3/n2 ? which commands or functions should use in matlab in order compute snr_before , snr_after? thanks billion putting time on helping me. what know calculating snr before : snrbeforenoise = mean( signal .^ 2 ) / mean( noise .^ 2 ); and snr after : residual_noise = signal - noise_reduced_signal; snr_after = mean( signal .^ 2 ) / mean( residual_noise .^ 2
