Simple Guide for using PDB to debug Python programs, and a simple guide for using pdb to debug python In Python, you can also debug programs like gcc/gdb, as long as you introduce the pdb module when running the Python Program (as

I've been working on Linux all the time, but I don't have much use for gdb. Because Ping du is using qtcreator to debug the program. Because of the work, it may not be possible to rely on qtcreator again. So I have a good study ~ Before why not deep use of gdb,qtcreator to bring certain convenience is on the one hand,

Label:PC Host: Ubuntu 10.4 Target board: TQ2440 Development Board, Linux kernel 2.6.30 Note: To use GDB for debugging, it is highly recommended to use NFS services, otherwise debugging can be cumbersome. Use the NFS service to refer to: S3C2440 Mount NFS File system1. OverviewThe so-called remote debugging, is the development Board to build a GDB server, while the program to be debugged is also located in t

of fflush refresh buffer, I try to find out, because the Linux platform does not support fflush, the function of this usage is only applicable in VC6, here we can also see that C language must cooperate with the Linux science, Otherwise, the standards in your mind are all MS, not C99 at all.Here, we test the program again, we will find that the source program is no problem. I also later found that their own oolong led to such a tangled debug, but som
