hello, I have a big problem.
When i try to install programs i get a error.
The error is :

checking whether the C compiler (gcc ) works... no
configure: error: installation or configuration problem: C compiler cannot create executables.

I have gcc :

root@linux:/home/manuel11g# gcc -v
Reading specs from /usr/lib/gcc-lib/i486-slackware-linux/3.3.4/specs
Configured with: ../gcc-3.3.4/configure --prefix=/usr --enable-shared --enable-threads=posix --enable-__cxa_atexit --disable-checking --with-gnu-ld --verbose --target=i486-slackware-linux --host=i486-slackware-linux
Thread model: posix
gcc version 3.3.4

What to do ?
Pls help.

Do you have binutils installed??

When i try to install them i get this :

root@linux:/home/manuel11g/binutils-2.9# ./configure --host=i486-slackware-linux
Created "Makefile" in /home/manuel11g/binutils-2.9 using "mt-frag"
/usr/bin/ld: unrecognized option '--as-needed'
/usr/bin/ld: use the --help option for usage information
collect2: ld returned 1 exit status
*** The command 'gcc -o conftest -g -O2 conftest.c' failed.
*** You must set the environment variable CC to a working compiler.

Well, I guess you should do:

export CC=gcc

It give me the same error.
When i try to compile a Hello_World.c it give me another error:

root@linux:/home/manuel11g/binutils-2.9# gcc Hello_World.c -o hello
Hello_World.c:1:22: iostream.h: No such file or directory
Hello_World.c: In function `main':
Hello_World.c:4: error: `cout' undeclared (first use in this function)
Hello_World.c:4: error: (Each undeclared identifier is reported only once
Hello_World.c:4: error: for each function it appears in.)
Hello_World.c:3: warning: return type of `main' is not `int'
root@linux:/home/manuel11g/binutils-2.9#

Well, that's because there are errors in your program

Hello_World.c:1:22: iostream.h: No such file or directory

something wrong with the way you include a header file here.

Hello_World.c: In function `main':
Hello_World.c:4: error: `cout' undeclared (first use in this function)

put after your includes this line of code:

using namespace std;

Hello_World.c:4: error: (Each undeclared identifier is reported only once
Hello_World.c:4: error: for each function it appears in.)
Hello_World.c:3: warning: return type of `main' is not `int'

the main function should return an int type.

This is my source code :

#include <iostream>

using namespace std;

int main()
{
cout << "Hello World \n";
return 0;
}

I copy him from the http://www.linuxquestions.org/questi...icle&artid=173 - a tutorial from this page :P
It is wrong ?

No it's not, but how do you compile your program?

I think i made it.
When i compile programs with g++ it works but when i want to "make" it give me another error :

make

Well, this again is not your compiler's fault. There simply are errors in the compiled code.

how to repair this errors ?

It seems you have not much experience with programming C or C++, so I think you're beter of trying to find some precompiled packages for this program.
