-coff, -elf, -aout

-coff, -elf, -aout

[Naveen Malik]

Hi,

when making a cross compiler from gcc we have three
options  -coff, -elf, -aout that generate a cross compiler that gives us the
binaries that are indipendent of any OS support.  Can anybody please help me
in understanding - what is the difference between these three options as all
of them are used to generate code for embedded applications but whaich
option to use?

OR where I can get the reference material for al these issues for defining
target.

Best regards

Naveen Malik

Doubt in file formats

HI,
we have diifrent file formats like aout,ELF,etc..
Why do we need such  diffrent formats??

Hi there,

I had also posted the same query on the help net but could'nt get any reply
from any gcc gurus.

Even if we take the case of embedded applications, we have -coff, -aout
and -elf formats there. but I am also not sure about the exact differences
in these formats.

Please, if any of the you in the gcc-help mailing list have answer, kindly
resolve the issue.

Regards

Naveen Malik

Sorting data points

[Deosaran Bisnath]

I am new to linux g++ & am not sure how to do this. Your help is most
welcome

there are about 50 data points like this, x and y

x             y
2.4          1
67.21       2
1.9           3
211.45      4


I want to sort x in ascending or descending order so the above are arranged
like this:

x              y
211.45      4
67.21        2
2.4            1
1.9            3


what is the fastest way to do this? thanks

Hi Deosaran,

 Your problem sounds a bit more like a home work
assignment than a GCC problem;) Any way, you might
want to look at the STL, find a suitable container
providing itterators and have a look at the sorting
algorithms in STL. This way you wont have to do
much coding yourself, and you will get a pretty
efficient solution:)

Yours sincerely,

Bjorn
