Hi,

I migrated from windows to Fedora6 linux a few months ago, and am still 
learning to make the best out of this fantastic OS....

I just installed GSL for my statistical research, but I installed it on 
a different folder than the one I wa supposed to. I should have 
installed /usr/include directory rather than /usr/local/include. So I 
should specify the path to this usr/local/inlcude/gsl everytime I run 
C/C++.

This is very simple newbie question, but how to specify the path in the 
process of ./configure, make, make install etc? I could just copy and 
paste all the files in the gsl directory in /usr/local/include to 
/usr/include by the chmod command....

I appreciate your help.

Thanks

Taka

Hi,

Very often (almost always) you can specify --prefix
./configure --prefix=/usr/

And all files will be written to /usr/include /usr/lib and etc, not
under /usr/local/

However there is a gsl package in FC6 repository try "yum install gsl"
and "yum install gsl-devel".

I wouldn't recommend that... packages put things in /usr, whereas things 
you built yourself default to /usr/local unless told otherwise. Keeping 
this separation has two positive effects: you can tell what is 
source-built and what isn't, and updating packages doesn't nuke things 
that have been source-built (ok, possibly a disadvantage, but more 
predictable).

/usr/local/include should be searched by default, you should never have 
to specify it. If the problem is the 'gsl' you could create symlinks in 
/usr/local/include (or even /usr/include) to /usr/local/include/gsl/*, 
but I wouldn't copy/move files.

I've never had much luck with curses myself, but:

to get this to print, you probably have to

    fflush(stdout);

since io is usually buffered until a newline. (On the other hand, I've
no idea if curses intercepts stdio to do its own thing.)

Sorry that's not much help,
Rup.

newbie question

[M.A-R. Abdullah]

Hi
I'mhaving problems trying to use getch(). In short, what is the simplest
way to use this. I have the following code but the problem is that the
screen is cleared when getch() is called. How can this be resolved?
(I am typing the program in, please excuse spelling errors, the original
does compile)


#include <stdio.h>
#include<curses.h>

int main(void)
{
  int i;
  WINDOW *win=NULL;

  win=initscr();

  cbreak();
  i=nodelay(win, 0);

  printf("This statement doesn't seem to get printed");

  i=getch();
  printf("This char is %c\n\r", i);
  printf("This statement is printed");

  endwin();
  return 0;
}

Thanks

MA

  Using the 'patch' command!!

  Change directory into the directory where you unpacked the gcc source
code.  This should be the directory where gcc-2.95.2 is a subdirectory, 
you don't want to actually be *in* that directory.  Make sure you have
a copy of the patchfile in that directory and type

patch -p0 < glibc-2.2.patch

(For further info about the patch command, try 'patch --help' or 'man 
patch' or 'info patch')

     hth,

[Stagner, Robert]

Hello,

i'm running RedHat 7.0 and would like to install gcc 2.95.2.  however, since
i have never installed gcc from source before, and as mr. alexandre oliva
mentioned on this forum not so long ago (Jan 18, 2001):

There are patches in the GCC platform-specific installation notes that
correct this compatibility issue.

how does one apply the patch to gcc ?  i've downloaded both the source for
gcc and the patch file from the gcc web-site, but the patch file is simply a
text file with references to code.

any assistance would be appreciated.

newbie question

[Craig Cowen]

I am going over a beginners book on ANSI C and it references a header
file conio.h and a function getche().
The function is suppose to get one character and force a return.
How can I use this with gcc or how can I get the same functionality.

uname -a
FreeBSD athlon 4.1.1-RELEASE FreeBSD 4.1.1-RELEASE #14: Fri Nov 24
19:36:27 GMT

cc -v
sing builtin specs.
gcc version 2.95.2 19991024 (release)

Thanks

I believe conio.h is a dos/windows specific header.

RE: newbie question

[Puneet Singhal]

try using getch instead of getche
use the foll command for compiling
  cc  [ flag ... ] file ... -lcurses [ library ... ]

and in the code incl the foll
#include <curses.h>

int getch(void);
