Ubuntu

Hi,

I need to install the GCC compiler on a my Linus machine.
First step is to run the ./configure command and here we need to specify
./configure --target="target machine name (CPU type-Manufacturer-OS)

or other way would be just give the command ./configure and it guesses the target name from the file config.guess.

uname -a in my system gives
Linux 137.132.80.158 2.6.25-14.fc9.i686 #1 SMP Thu May 1 06:28:41 EDT 2008 i686 i686 i386 GNU/Linux

So I tried giving the format CPU type-Manufacturer-OS for my system as
i686-unknown-Linux

Also tried adding a new case in config.guess file to add my case ie for i686.

It keeps giving error "Invalid Configuration" if I directly give in the configure command or edit the config.guess file.

How do I give the rite values of CPU type-Manufacturer-OS ...Is there any command to find the values.Please let me know as Iam not able to proceed forward as configure command itself gives error.

You cannot build gcc without a C compiler! It's a chicken-and-egg problem.

You ought to install the binary version that comes with whatever distribution you're running, there's no reason to compile it yourself.

Dear viji19812001,

Please post the output of this command:

Code:

gcc -v

and also:

Code:

cat /proc/version

Hi Neo,

gcc -v gives the following output:

The other command cat /proc/version says File does not exist......


So do I need to use the target name which comes in gcc-v in my configure command. Please let me know.

Regards,
vijaya.

Well, we found out you have gcc installed already, so that is a good thing. We found out that gcc was configured with

Code:

target=i386-redhat-linux

so that should work again.

However, since gcc is already installed, maybe you don't need to install again?

Also, I am a bit confused why

Code:

cat /proc/version

gives a file does not exist error, but never mind, I assume you are running some version of redhat, per the output of gcc -v

Hi Neo,

Thanx!!!!

Configure command works now with the values i386-redhat-linux.....

Also sorry I had done some mistake cat /proc/version gives the following output:

Linux version 2.6.25-14.fc9.i686 (mockbuild@) (gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC) ) #1 SMP Thu May 1 06:28:41 EDT 2008

Let me actually tell you what Iam trying to do so that you could help me in a better way.
Iam trying to install the opentv SDK3.2 kit (interactive tv application ) from the link Welcome to OpenTV .
Thier code is in ansi C and needs to be complied using the kit to get the ocode as the output.
Iam doing this for the first time and just following the instructions given in thier install file.


Install File says:

1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system. If you're
using `csh' on an old version of System V, you might need to type
`sh ./configure' instead to prevent `csh' from trying to execute
`configure' itself.

2. Type `make' to compile the package.

3. Optionally, type `make check' to run any self-tests that come with
the package.

4. Type `make install' to install the programs and any data files and
documentation.



Now Output for configure in my system is as follows:
I ran the command from the gcc2.60 directory as it has all the .c files present.

[vijv@137 gcc-2.60] ./configure i386-redhat-linux
Linked `config.h' to `./config/i386/xm-linux.h'
Linked `tm.h' to `./config/i386/linux.h'
Linked `aux-output.c' to `./config/i386/i386.c'
Linked `tconfig.h' to `./config/i386/xm-linux.h'
Linked `hconfig.h' to `./config/i386/xm-linux.h'
Linked `md' to `./config/i386/i386.md'
Merged i386/x-linux.
Merged c++ fragment(s).
Created `./Makefile'.
Merged i386/x-linux.
Created `cp/Makefile'.
Links are now set up for target i386-redhat-linux.


Now when I give make command as per the second step in the same directory ,it gives me errors....Am I doing something wrong ?....or is this the rite way to do it.
Do let me know in case u need any more info from me.

output of make command:

make

Thanx for ur time,

Hi viji19812001,

First of all, the rules of the forums are to write in English, correct English, so please do not write "Thanx!!!!" and "Thanx for ur time".... please write "Thanks" and "Thank you for your time" These are the rules. We don't support invented cyberchat languages here.

Second, I am glad to see you made some progress. I don't see where your attempt to compile failed. The output shows warnings. Warnings are not failures.


I think your binaries may have compiled OK.
