hi, i'm _sure_ this is a noob question. I am a Java programmer by trade, haven't done 'C' in years. I am trying to develop some code for a personal project. I started a 'C' console project. using the GNU manual : http://www.gnu.org/manual/glibc-2.2.3/html_node/libc_175.html#SEC184 I am trying to use the 'getline' function. i'm getting an 'undefined reference' error from the Linker (not the compiler). Do I need to tell the linker to use some lib that isn't setup by default ? Does this have something to do with 'C' vs. 'C++' ? TIA, Tony ===== |

Forget any mention of a gets() function. It should N.E.V.E.R. be used because of buffer overflow problems. /Per W On Mon, 16 Sep 2002, PhrostByte wrote: > Maybe your looking for gets() and fgets()? > > -----Original Message----- > From: dev...@li... > [mailto:dev...@li...] On Behalf Of The > Tone'ster > Sent: Monday, September 16, 2002 11:14 AM > To: list dev-cpp-users > Subject: [Dev-C++] unresolved external/linker error > > > > hi, > > i'm _sure_ this is a noob question. > > I am a Java programmer by trade, haven't done 'C' in years. > > I am trying to develop some code for a personal project. > > I started a 'C' console project. > > using the GNU manual : > > http://www.gnu.org/manual/glibc-2.2.3/html_node/libc_175.html#SEC184 > > I am trying to use the 'getline' function. > > i'm getting an 'undefined reference' error from the Linker (not the > compiler). > > Do I need to tell the linker to use some lib that isn't setup by default > ? > > Does this have something to do with 'C' vs. 'C++' ? > > TIA, > Tony > > ===== > > > > ------------------------------------------------------- > This sf.net email is sponsored by:ThinkGeek > Welcome to geek heaven. > http://thinkgeek.com/sf _______________________________________________ > Dev-cpp-users mailing list > Dev...@li... > TO UNSUBSCRIBE: http://www.noicys.cjb.net/devcpp/ub.htm > https://lists.sourceforge.net/lists/listinfo/dev-cpp-users > > > > > ------------------------------------------------------- > Sponsored by: AMD - Your access to the experts on Hammer Technology! > Open Source & Linux Developers, register now for the AMD Developer > Symposium.

#include <iostream.h> |

To recap : I was trying to use the "getline()" function in the GCC/GNU distro as included in Dev-Cpp v5 beta. I was getting an error from the linker. I looked into the <iostream.h>. This appears to be a C++ header. I am developing/compiling as 'C'. I tried it anyway. compile errors. to be expected. The GCC docs seem to imply that this is a <stdio.h> function that can be used from 'C' code ? ??? TIA, Tony --- Carlos García del Monte <cg...@wo...> wrote: > #include <iostream.h> ===== |

uhh ... I think I get it now. These functions are actually part of the "GNU libc" ... not part of the GNU compiler suite and any runtime libs it contains ? so ... I would need to have this stuff, and it looks like the source is not portable to windows ?

You can still use fgets. It's just the gets that must not be used, since it doesn't take the size of the input buffer as a parameter. /Per W On Tue, 17 Sep 2002, The Tone'ster wrote: >=20 > uhh ... >=20 > I think I get it now. >=20 > These functions are actually part of the "GNU libc" ... not part of the G= NU > compiler suite and any runtime libs it contains ? >=20 > so ...

Oh, yes, iostream is C++, I should have notice it, stdio has no getline.
There are no C getline(), only C++, the one from iostream and the other w=
hich come
=66rom string and the other string classes. And get is either from iostre=
am.
You can make your own getline, overload it
void getline(char *buffer, int size){
char test =3D 'a';
for (int i =3D 0; i < size && test !=3D '\n'; i++){
buffer[i] =3D get();
test =3D buffer[i];
}
}

Forst of all, I didn't know that overload existed in C.
Second. Why write a new getline with - almost - the same function as
the already existing fgets?
Third. The sample code never terminates the loaded buffer after it finds z
newline character, or runs out of buffer space.

I have the cpluplus reference, and by it and the name fgets is for working for files (I should have add it) but I assumed the question was about stdin. stdin is also a file. The console is a file (named `con'), everything is a file. Hell, in Unix, Count Dracula is a file. ___________________________________________________________ Abhijit Shylanath E-mail: mu...@gm... || ibr...@bi... Web-site: http://mudeth.tripod.com/ |

Yes, fgets(buf,sizeof(buf),stdin) works ok to read from stdin. /Per W On Wed, 18 Sep 2002, Carlos Garc=EDa del Monte wrote: >=20 >=20 > Per Westermark escribi=F3: >=20 > > Forst of all, I didn't know that overload existed in C. >=20 > Sorry, my english is not perfect, I got the "license" of saying overload,= I noticed it > would be best not having it after sending.

yeah. this is what the doc for GCC said, thus my attempt to use the alternative getline(). somebody else suggested #include <iostream.h>. I'll try this. The GCC doc said that this function was part of <stdio.h>. Cheers, Tony --- Per Westermark <pw...@ia...> wrote: > Forget any mention of a gets() function.
