Asp Forum - Installing Ruby on Linux - Error

Centipeed

I'm new to Linux, so it may well be that I'm missing some trivial.

However, I have Ubuntu installed on my Laptop, and I downloaded the
Source for Ruby (ruby-1.8.5-p12), copied it across to my laptop (My
laptop does NOT have internet access, so I can't just apt-get,
unfortunately), and tried the following:

/configure

It starts working, then right after "checking for C compiler default
ouput file name...", I get this:

"configure: error: C compiler cannot create executables"

Can anyone help me out with this one?

Try:

echo "int main(){return 0;}" > test.c
gcc test.c

If it fails, gcc probably doesn't have correct permissions or isn't
installed right.

Either way, you'll probably get a more specific error message.

If it works, ./configure is lying.

Perhaps sudo first?

sudo ./configure

I think Ubuntu doesn't install any developer tools by default. You need
the GCC compiler, autoconf and friends, and the GNU binutils. Probably
there's a package with everything you need, possibly called "developer
tools" or something similar.

You'll need to install the package "build-essential" which will pull in a
GCC, G++, linkers, make, and the basic header files which belong in /usr/
include.

If you just have GCC installed, but not a linker, then your C compiler
cannot create executables and you'll get that error.

Right. It's called build-essential.

If the C compiler is installed, then

$ gcc --version

will return the version of the C compiler. I had something similar
happen on one of my machines last week, and I *do* have GCC installed.
It turned out my CFLAGS environment variable was messed up, so if you do
have GCC, check "CFLAGS" for sanity. What configure does is simply
attempt to compile something -- if it gets an error, you get that
message. :)

Centipeed,

Out of the box Ubuntu lacks developers tools: compilers,
libraries, etc. Please post the output of ./configure if you want
peopple to take a deeper look at what is missing in your setup. If you
are newbye to linux I would strongly suggest to stick to version 1.8.4
that you can install using apt (download the package and copy it to
your laptop), unless you really need the features available in 1.8.5

Now I'm starting to suspect you're just making things up.

You can't prove anything. You keep telling us that all your personal
details are private for reasons of national security.

You're a postal inspector, the dirty federal law enforcement agency
that snoops through people's mail and tries not to get caught. Your
favorite color is magenta.
