First, the build bug occurred when I tried to install gmp 5.0.2 from
source at the final install cli step, "sudo make install". When I looked
through the output, I noticed that at some point that because one of the
directories in the install path had a space, it did not correctly recognize
the escape sequence, and broke off after the first space, which then
referred to a directory which did not exist and the installation failed.
Spaces in file names or directory names is a no-no under Unix. We are
not going to even try to make that work with GMP, since such an attempt
will surely be quite futile.
The second bug I think is more complex. I'm making a proof of concept
program for a compression algorithm which reads in a whole file as a single
number, then uses primes to shrink it down. Every time I run the program,
different primes are indicated as being important and relevant to shrinking
the number as divisors with no remainder. I've tried using the program on
filed which are larger than 1MB, but my machine takes too long to load it
into RAM as a single number--this is not the issue. The issue is that it
appears that the number is somehow corrupted each time its read in. I have
source of the program which causes this issue attached to this email. The
cli commands I use to build the program are: "g++ ~/Ubuntu\
One/research/oppf/v1.cpp -lgmp -lgmpxx -std=c++0x" and " ./a.out
/home/anadon/Downloads/CIS\ 255\ MTE\ REVIEW\ 2\ by\ WEIRAUCH.docx".
We can only wish you luck with debugging your program!
./configfsf.guess requires sudo permissions, then cannot be found to run.
Is this the bug being reported? In that case, you need to give a few
more detail on what the symptoms are.
