Installing gcc

[Hetendra]

I am having problem in installing gcc in my respberry pi , Can anyone please tell how to replace jessie to scratch?

[joan]

I think gcc is pre-installed in all Raspbian versions on the Raspberry Pi.

Why do you mention Scratch?

[Hetendra]

Thankyou for response
I m following one article for installing the gcc and one step was to replace the jessie by scratch
By command open /etc/apt/sources.list
So now please suggest what should I do I want to dp programming in C& C++

I took that to mean 'reinstall Jessie from scratch'. In which case, simply backup and re-image the SD card.

Sorry sir I dint get that
Can you tell how to backup n reimage?

And I m also having one more problem in opening pdf file it is not
Supported in raspberrypi

If

Code: Select all

sudo apt install build-essential

doesn't work, then there's something wrong with your Raspbian image or your network connection.

Xpdf should be able to open them. I can't remember if it's installed by default (it's on mine and I don't remember installing it), if not then you can install it with either

Code: Select all

sudo apt-get install xpdf

or from the desktop, go to the Menu->Preferences->Add/Remove Software. Choose Publishing from the list on the left, then scroll down the list on the right and select Portable Document Format (PDF) reader (it'll be near the bottom of the list).

If, when you try to open a .pdf file from the desktop, you get a window asking to choose an application to open with, click on the + next to Accessories and PDF Viewer should be there. If it is, select it, make sure the tick box at the bottom for Set selected application as default for this type is ticked, click Ok. From now on it xpdf should open .pdf files for you.

Ah yes, just like a cryptic crossword, obvious when explained.

Can you stop adding new questions to your old thread, it's just confusing for everyone. Start a new thread for a new unrelated question.

Search for omxplayer and omxplayergui that works as long as your RPi has the audio configured correctly.
