 Posted: Thu Sep 13, 2007 3:29 pm Post subject: Gcc problems [SOLVED] |
 |
|
I tried to emerge gcc-3 yesterday to compile qemu, but it didn't succeed. I think that's the reason of the problem.
Now, I see there are some things wrong with gcc. When I compile a simple *.cpp, I get lots of errors, because it can't find iostream and other include files.
This is what I get if I try to compile just an usual program:
| Code: | ./main.cpp:2:20: iostream: No such file or directory
./main.cpp:5:19: cstring: No such file or directory
/main.cpp: In function `void openFile()':
./main.cpp:34: error: `cout' was not declared in this scope
./main.cpp:34: error: `endl' was not declared in this scope
./main.cpp:40: error: `cerr' was not declared in this scope
./main.cpp: In function `int main(int, char*)':
./main.cpp:55: error: `cerr' was not declared in this scope
./main.cpp:55: error: `endl' was not declared in this scope
./main.cpp:70: error: `cerr' was not declared in this scope
./main.cpp:70: error: `endl' was not declared in this scope
./main.cpp:74: error: `cout' was not declared in this scope
./main.cpp:74: error: `endl' was not declared in this scope
./main.cpp:89: error: `cerr' was not declared in this scope
./main.cpp:89: error: `endl' was not declared in this scope
./main.cpp:93: error: `cout' was not declared in this scope
./main.cpp:93: error: `endl' was not declared in this scope
(And so on...)
|
I've done a slocate iostream, and this is the output:
| Code: | /usr/lib64/gcc/x86_64-pc-linux-gnu/4.1.2/include/g++-v4/iostream
/usr/lib64/gcc/x86_64-pc-linux-gnu/4.1.2/include/g++-v4/backward/iostream.h
/usr/lib64/fpc/2.2.0/units/x86_64-linux/fcl-base/iostream.o
/usr/lib64/fpc/2.2.0/units/x86_64-linux/fcl-base/iostream.ppu
/usr/portage/sci-mathematics/geomview/files/geomview-1.8.1-stdiostream.diff
/usr/portage/app-misc/aldo/files/aldo-0.0.11-iostream.diff |
And when I type in this command, I get this output:
| Code: | frans@SkyBox ~/projecten/cpp/0004-t2k $ gcc-config -X
/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2:/usr/lib/gcc/x86_64-pc-linux-gnu/4.1.2/32/include/g++-v4 |
So, I guess the files are on my hard disk. How could I tell gcc where these files are?

what does
display?
Make sure its set to 4.1.2, and do a re-boot to be sure all sessions are updated... gcc-config can be a pain sometimes
You could try re-installing gcc from a binary package, or from the stage3 tarball in the worst case, to get a working compiler setup. |

I think this is ok?

What is the command line you use to comile your simple *.cpp?
Make sure to use g++ not gcc (since it is C++ code). |

Can I unemerge gcc, and emerge it again?
Or do I have compile problems with compiling without compiler? (lol)

If you lose your only compiler, you won't be able to compile.
Hence, re-emerge from a binary package, or from the stage-3 tarball (tricky). |

Could you please post a minimal (!) version of your main.cpp
that still exhibits this problem so we can have a look! |

I'm sorry, i could not post that code, but I got the same problem with just a minimal hello world-program.
| Code: | //main.cpp
#include <iostream>
using namespace std;
int main()
{
cout << "Hello World" << endl;
return 0;
} |
| Code: | g++ ./main.cpp -o main
./main.cpp:1:20: iostream: No such file or directory
./main.cpp: In function `int main()':
./main.cpp:6: error: `cout' was not declared in this scope
./main.cpp:6: error: `endl' was not declared in this scope |

Where could i get an AMD-64 binary package?

Unfortunately I don't know of any binary package repositories. You could make a binary package yourself on a livecd or vmware image using emerge. Or on another PC. Or ask a friend to send you theirs over the net... You could figure out just the files that are missing from your include directory and extract those from the gentoo_x86_64-stage3.tar.gz
Cheers,
Mitch |

g++ doesn't seem to find the header files. Are you sure
you did a
| Code: |
source /etc/profile
|
after setting your compiler via gcc-config? |

I did not change my compiler, it didn't work (because i could not get it installed). But when I am at home i'll give this a try.
I tried it, and have the same problem. I'm going to download the stage-3 tarball. Maybe it works...

Can I unpack the stage 3 to / without using the gentoo cd? (i already have the iso, but don't have any empty cd  )

(sorry for the quadpost  )
I wanted to check which files needed to be replaced, and did a whereis g++. I found out there was an executable called g++ in another directory. That one works right. But when I use the command g++ it does not work.
I have now solved the problem. I just made a soft link from /usr/bin/g++ to /usr/locala/bin/g++ .
| Code: | | ln -s /usr/bin/g++ /usr/local/bin/g++ |
Thanx for everyone who helped me
