Compiler stuff

1. debugger:

1) purify g++ -g exe_name file_name => exe_name in Solaris.

2) insure g++ -g exe_name file_name => exe_name in Linux

3) gdb stuff: g++ -g exe_name file_name => gbd exe_name =>run (params)

2. limit coredumpsize unlimited
3. file file_name to see if an executable file is static or dynamic
4. ldd same as 3

Use SecureCRT to transfer files:

1. “sz filename” to send a file to my desktop from a remote workstation
2. “rz filename” to receive a file from my desktop

Linux Compile Makefile

1. gcc …. –I/s/…/include for Include and –L/s/…/lib for the library PLUS –lX…to the links
2. To plot in Linux X window, need to include motif stuff Xm & X11R6 (see some of the instructions at www.cs.wisc.edu/csl/ page)

ex) #!/bin/sh

gcc -o dosxyz_show -DMY_COLOR dosxyz_show.c \

-I/s/X11R6/include -L/s/X11R6/lib \

-I/s/motif/include -L/s/motif/lib \

-I/s/xpm/include -L/s/xpm/lib \

-lXm -lXt -lXmu -lXp -lX11

3. dos2unix converts Windows text file to Unix text file

Perl Script

Note: You do not need to “chmod +x filename” every time. Once is enough.

XV on Linux:

How to copy and save a picture from any format using xv?

That's a very strange Linux installation that you have!

Is this some Linux emulation on a Windows computer ???

I suspect, the order you link the libraries may be the

reason for the program to fail.

I don't know why, but the Motif, Xt and X11 libraries

MUST be linked in a particular order, otherwise

the executables fail to run: you have to use

-lXm -lXt -lX11

I don't know what Xmu and Xp do (unless you changed

something in dosxyz_show, you don't need these),

but I would link them BEFORE X11, i.e. try to use

-lXm -lXt -lXmu -lXp -lX11

instead of

-lX11 -lXt -lXm -lXmu -lXpm -lXp
