c++ - How to make Valgrind debugger step through a program -

-

good morning, trying use valgrind debugger step through program.

my valgrind command line valgrind -tool memcheck --leak-check=full --db-enable=yes ./matchupacurate.exe.

i using valgrind-3.5.0 on centos linux release 5.5 gdb version 7,0.1-23.el5_5.2.

i enter yes when valgrind asks question attach debugger. then, valgrind debugger returns with: 4428: return new tuple2<int,a>(2, i++, p->next());

when try use gdb step or continue command, valgrind says

[new thread 0x410fd10 (lwp 6548] cannot find user-level thread lwp 6551: generic error.

when try use valgrind --single-step=yes debugger option on valgrind command-line, valgriind says bad option aborting.

could valgrind users show me how step through c++ source code or continue through program? thank you.

you can vgdb in 3.7.0 release. release notes:

  • gdb server: valgrind has embedded gdb server. means possible control valgrind run gdb, doing usual things gdb can (single stepping, breakpoints, examining data, etc). tool-specific functionality available. example, possible query definedness state of variables or memory within gdb when running memcheck; arbitrarily large memory watchpoints supported, etc. use gdb server, start valgrind flag --vgdb-error=0 , follow on-screen instructions.

there's more info in valgrind online manual.

i want make logharitmic fit. keep getting runtime error: optimal parameters not found: number of calls function has reached maxfev = 1000 i use following script. can tell me go wrong? use spyder still beginner. import math import matplotlib mpl scipy.optimize import curve_fit import numpy np #data f1=[735.0,696.0,690.0,683.0,680.0,678.0,679.0,675.0,671.0,669.0,668.0,664.0,664.0] t1=[1,90000.0,178200.0,421200.0,505800.0,592200.0,768600.0,1036800.0,1371600.0,1630800.0,1715400.0,2345400.0,2409012.0] f1n=np.array(f1) t1n=np.array(t1) plt.plot(t1,f1,'ro',label="original data") # curvefit def func(t,a,b): return a+b*np.log(t) t=np.linspace(0,3600*24*28,13) popt, pcov = curve_fit(func, t, f1n, maxfev=1000) plt.plot(t, func(t, *popt), label="fitted curve") plt.legend(loc='upper left') plt.show() your original data t1 , f1 . therefore curve_fit should given t1 second argument, not t . popt, pcov = curve_fit(func,...

binding - How can you make the color of elements of a WPF DrawingImage dynamic? -

-
we have need make vector graphic images change color of elements within graphic @ runtime. seem setting colors based on either static or dynamic resource values wouldn't work. want have multiple versions of same graphic, each abilty set graphic elements (path, line, etc) different colors don't think dynamic resource approach work. leaves data binding seems right approach. update graphic use data binding expr instead of hard-coded brush color so: <drawingimage x:key="graphic1"> <drawingimage.drawing> <drawinggroup> <drawinggroup.children> <geometrydrawing geometry="f1 m 8.4073,23.9233l"> <geometrydrawing.pen> <pen linejoin="round" brush="{binding line1brush, mode=oneway}"/> </geometrydrawing.pen> </geometrydrawing> <geometrydrawing geometry="f1 m 3.6875,2.56251l"> <geometrydrawing....
