python - Using gnuplot to generate a set of numbered images -


i'm newbie in python , ask you, how can images (a lot of images) made gnuplot.py variable in name? have function, creates single image:

def printimage(conf, i):    filename = str(i) + "out.postscript"    g = gnuplot.gnuplot()    g.title('my systems plot')    g.xlabel('date')    g.ylabel('value')    g('set term postscript')    g('set out filename')    databuff = gnuplot.file(conf, using='1:2',with_='line', title="test")    g.plot(databuff)

and function used in loop:

i = 0 row in data:    config_soubor.write(str(i) + " " + row[22:])    printimage("config_soubor.conf", i)    = + 1

i still can't rid of error "undefined variable: filename".

thanks, majzlik

right now, python script passing

set out filename

to gnuplot. there 'filename' part of command string; variable filename set in script not being passed gnuplot. try replacing

g('set out filename')

with

g('set out "'+filename+'"')

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
