configure: error: cannot run C compiled programs

[Dimesh]

when trying to install program by compiling it that what i got:

sudo sh configure

checking for a BSD-compatible install... /usr/bin/install -c
checking whether build environment is sane... yes
checking for gawk... no
checking for mawk... mawk
checking whether make sets $(MAKE)... yes
checking build system type... x86_64-unknown-linux-gnu
checking host system type... x86_64-unknown-linux-gnu
checking for style of include used by make... GNU
checking for gcc... gcc
checking for C compiler default output file name... a.out
checking whether the C compiler works... configure: error: in `/media/pro-gam/2-my-download/cairo-dock-2.1.0':
configure: error: cannot run C compiled programs.
If you meant to cross compile, use `--host'.
See `config.log' for more details.

i see in my ubuntu installed software that there is a g++ installed in my pc.

??!!

You should never `configure` or `make` with `sudo`,
only `make install` may require admin privilege - and not even then
if you are installing to your own personal software collection.

Make sure you have the "build-essential" package installed.

And, again, the conventional build looks like:

./configure
make
sudo make install

Thanks to you MR.asmoore82

You should never `configure` or `make` with `sudo`

i do but:

./configure
bash: ./configure: Permission denied

Make sure you have the "build-essential" package installed.

sudo apt-get install build-essential

./configure
bash: ./configure: Permission denied

Excellent! It's really important not to mask other errors…

Now I'm thinking that either the source code was extracted as `root` or
is stored on a non-Linux filesystem. Neither of these is ideal.

Sorry i do not understand Mr.

Sorry i do not understand Mr.

You extracted the tar file with sudo. Don't do that.

[Dimesh]

but i did right click and choose extract here
i do not extract with terminal
!

I do this all the time.

I have created a build directory under my home:

mkdir ~/build

Change into the directory:

cd ~/build

Assume I downloaded openssl-1.0.0d.tar.gz and it was saved in my Downloads directory I would extract it to the build directory that you are currently in:

tar zxf ~/Downloads/openssl-1.0.0d.tar.gz

When you get your command prompt back you will have a directory for the openssl code. CD in to that directory:

cd ~/build/openssl-1.0.0d

Run the configure script:

./config

Make the application:

make

Install the application (If you want):

sudo make install

Did you run nautilus with gksu or something? What does ls -l configure show?
