[Q] Detailed instructions for this program [R] - Galaxy Tab 10.1 Q&A, Help & Troubleshooting

http://rwiki.sciviews.org/doku.php?id=getting-started:installation:android
This page describes how to install a program on android based devices, but I am not able to understand the (rather short) instructions. I hope that anyone here can further elaborate on the steps required to run this program on a tablet.

I don't know that much about linux/android but I think enough to help you.
First of all, you need to have a rooted Tab and Busybox installed on your Tab. If you don't have that, wel.. You should try to figure that out first.
Then you need some knowledge of ADB or have a Terminal Emulator installed on your Tab.
You can pm me in Dutch if you need help.

Actually, is really simple to install. There's no need to use adb (root is needed to create /data/local/gcc), the only requisite is a terminal emulator and busybox. I'm using Better Terminal Emulator Pro, but a free alternative with "all included" is Terminal IDE.
Following the guide, first get the 3 files, do this from the tab (in my case, sometimes the default browser doesn't work with mediafire, use Opera if this happens to you).
Now open your terminal emulator (for moving the files and create the folder a file manager can be used, but in my opinion that's cumbersome). All the following commands are executed from the terminal.
First, get root:
Code:
su
(A prompt dialog will request root permission)
Now, create the directory:
Code:
mkdir /data/local/gcc
From this point, root isn't required, so you can do it as a normal user. To change from root to user:
Code:
exit
Create the directory:
Code:
mkdir /data/local/gcc
Now move the downloaded files (change the path "/sdcard/Download" according to your case)
Code:
mv /sdcard/Download/android_gcc_r2a.tar.bz2 /data/local/gcc
Code:
mv /sdcard/Download/android_gcc_supplement.tar.bz2 /data/local/gcc
Code:
mv /sdcard/Download/android_R_r1a2.tar.bz2 /data/local/gcc
Move to the directory
Code:
cd /data/local/gcc
Extract the downloaded files
Code:
tar xjf android_gcc_r2a.tar.bz2
Code:
tar xjf android_gcc_supplement.tar.bz2
Code:
tar xjf android_R_r1a2.tar.bz2
Now you need to "tell" to the system where R is installed so it can be recognized by the system.
Code:
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/data/local/gcc/lib
Code:
export PATH=$PATH:/data/local/gcc/bin
You can (and you ought to) put this lines in your ~/.bashrc. If you are using Terminal IDE, is very easy, do
Code:
nano ~/.bashrc
and write the two lines.
That's it. In the terminal type
Code:
R
And you can start using it (I can't tell you about how to use R as I don't use it, but I guess you already know how to).

First of all great thanks for this post. I have now been able to make progress, although I run aground in the move part, I get a permission denied when I try to create the directory /data/local/gcc on the main system (i.e. my files are in mnt/sdcard/blabla and I want to create the target directory.
Might this be due to not being rooted? - I think I am rooted (Titanium backup runs ok)

Sorry, my bad. I forgot that very important part. You need root only for that part.
All the other steps are the same, just start with root:
First, get root:
Code:
su
(A prompt dialog will request root permission)
Now, create the directory:
Code:
mkdir /data/local/gcc
From this point, root isn't required, so you can do it as a normal user. To change from root to user:
Code:
exit
Now move the downloaded files (change the path "/sdcard/Download" according to your case)
Code:
mv /sdcard/Download/android_gcc_r2a.tar.bz2 /data/local/gcc
.
.
.
.
All the other steps.
In case you get a "permission denied", keep doing the steps as root.

That was really helpful, thanks again. I can now run the program, that part is clear. Tithe only thing I cannot get done is writing the exports in the bashrc, I see the text but cannot save in this, I guess I need to use the ^X sort of commands but how does that work from a soft keyboard?

That's ctrl+x (^ means the key ctrl or control), use another keyboard like this one: https://play.google.com/store/apps/details?id=org.pocketworkstation.pckeyboard
Don't forget to activate it in settings>language & input.
