Global Scope |
The text states the following:
>>> import globals
>>> help(globals)
Will result in...
"Help on module globals:
NAME
globals
.
.
.
DATA
var1 = 3
var2 = 4"
In actuality the data is as follows:
DATA
var1 = 0
var2 = 1
The latter is correct, because globals.py initialized those global variables to 0 and 1, respectively, and also because the module was only imported at that point (i.e. nothing was executed).
Slightly later in the text, one encounters the following command:
>>> globals.Function2()
That does cause var1 and var2 to take on values 3 and 4, respectively. So, perhaps that is how the error was introduced in the text.
If you concur, please include this change in the book's next update.
Thank you.
PS - The Safari Books Online version does not include page numbers, so it is impossible to provide an accurate "Page number of error:*" as required by the online form at www.oreilly.com/cs/catalog/create/errata/?b=5217
Please fix it. I apologize for having to enter a bogus page number.

Middle of page |
In the middle where the book listed steps to compile, link, and execute the example sine_print.c code module, first step is correct:
% gcc sine_print.c -o sine_print
Running this on my Ubuntu system resulted the following linker error from the gcc compiler:
/tmp/cc286NYF.o: In function 'main':
sine_print.c:(.text+0x5e): undefined reference to 'sin'
collect2: ld returned 1 exit status
$
The step needs to include additional compiler flag -lm to fix this error. Step could be:
% gcc sine_print.c -lm -o sine_print
which worked for me.
regards,
Neal

Third "for" loop in datapoint.c listing |
I think the third "for" loop needs to be:
for (i=0; i>=0; i++) {...
instead of:
for (i=0; i>0; i++) {...
Also:
When I print out the values of pointers stored in the array of pointers, the address interval is 24 bytes rather than the 12 bytes I would expect, since each datapoint structure is 12 bytes long. Why is that?
