/usr/bin/g++: execution denied

[sunil_7]

We downloaded a tar file for gcc and just untar it on hp machine. It did not ask for any installation procedure. It was working fine till yesterday. But, after that whenever I run any of the command in gcc, it gives the following error:

sh: /usr/bin/g++: execution denied

Although all other commands, which are native ones, are working fine.
I checked up, by working with root password and also, by giving 777 permission to the folder itself recursively.

But the problem is persisting.

If it was working fine and now it doesn work, then I would suspect that the file has somehow become corrupt. What do you get if you do a file on the executable, i.e.:

file /usr/bin/g++

you should get something like:

PA-RISC1.1 shared executable dynamically linked

I get the following output
# file gcc
gcc: awk program text

But this is not the only commands what all commands are there in gcc folder are giving error. but the core commands are not giving any error.

do u have any idea of any site, from where we can download compiled gcc compiler for hp. From the gnu site, we have to compile and then use.

Sounds like all your executables are bad. You can dowload gcc from HP's devresource page:

Forgot to mention that the devresource site has binaries for 11.0 and 11i. If you need the gcc for 10.20 you can get it from the HP porting center. Remember to grab binutils also as this is a requirement for the compiler:

Hi Sunil,

Since gcc was working fine for sometime, is it possible someone overwrote the binary?

If you still have the tar file you downloaded, try untarring it first and see if that fixes it, if not you may have to download it again.

Hi Sunil:

The other thing that may have happened is that a bad makefile or script may be clobbering /usr/bin/g++ rather that writing to the correct file.

Thanx santash

I could download it and it is working fine.

As Mr. Suntosh asked, I have downloaded gcc from the above mentioned site. I want to know, as by default on hpux11.0 it is aCC header files and libraries, which are set. When we compile the code with g++ will it automatically include the header files of gcc and while linking take libraries of gcc, rather than aCC. I am not including any path for header files of gcc as it gives the errors.
