I've seen similar questions all over many forums. Hopefully someone will be able to explain to me how I can resolve my error at the least and possibly help me to understand how to troubleshoot this sort of thing in the future.

Anyhow, here is the result after executing the './configure' command:

checking how to run the C preprocessor... /lib/cpp
configure: error: C preprocessor "/lib/cpp" fails sanity check
See `config.log' for more details.

Here is the result of the config.log:

Welcome to LQ.

You could start with the obvious missing things.
"missing stddef.h" > > = 'linux-headers' ?
( kernel-headers ? )

And check if 'glibc-devel' = 'libc6-dev' is installed.

How to ask a question ? It is appreciated that you
inform about the Linux system used every time a question
is asked.
And which program produced the config log ??

Thank you for your prompt reply.

I really liked the links you provided on "How to ask a question". I can certainly make use of that in other places as well.

Regarding the Distro. I am using Foresight Linux v. 2.0.5 Foresight Linux I also found this link on the forum however it seems quite outdated on the version. LQ Foresight Review As far as the software that I am trying to install currently, it is Dropbox

I reviewed the specific packages that you mentioned in your post and I am unable to locate any of them for install. I have ensured that I have almost every possible package of the 'gcc' and others mentioned via other posts in this forum.

Is there another way I can download the necessary packages using the command line? It is 'sudo conary install/update 'package'' however, I am not sure where they can be located or if I must download the source and again compile it. If this is the case, I can do that if you can help me to locate the necessary source packages.

Again, thank you for your assistance.

Foresight is probably not the best choice for a
developing system. On Foresight 2 I could not even
install a gcc, and packages ready to install from
the Foresight site is less than 10 !! ??

I think Foresight is meant just to be an easy to
use OS, with the applications already installed.

There is a build-tool ( to help emerge / build
applications), it wouldn't install too.

Suggest : Use another Linux OS, anything else
from top 10.

Please see this wiki page for the commands to setup your appropriate build environment with Foresight:
