Firstly check whether the module has been packaged for debian e.g. aptitude search lib | grep perl
will give a large list of packages. If the one you want is listed here then install it via aptitude install. If, however, it is not packaged, then as root, do perl -MCPAN -e 'install Name::Of::Module'

I was comparing the relative speeds of programming languages on the Pi.

All linked from http://www.fourtheye.org/projecteulertable.html - I did not post this initially because I did not want to be flamed for posting the solutions to the problems (you are supposed to think through the problems yourself!).

I wrote the first 25 problems from http://projecteuler.net/ in a few different languages (Perl, C, C++, Python, Java, Forth and ARM assembly language) using as natural a style as I could in each language and generally avoiding extensions e.g. boost in C++. I am interested in ARM assembly language, a...

Is there any reason why you want to cross-compile? You could use an ssh client from your desktop machine and use the native compiler on the pi?

If you install gcc (or clang) via "aptitude install gcc" or "aptitude install clang" then you can compile and run C programs natively.

That helps me. Now I can test the defaults of both compilers. bob@sweden:~/src/c$ clang -S sqrttest.c bob@sweden:~/src/c$ mv sqrttest.s sqrttest.s.clang bob@sweden:~/src/c$ clang -mfpu=vfp -S sqrttest.c bob@sweden:~/src/c$ mv sqrttest.s sqrttest.s.clangvfp bob@sweden:~/src/c$ gcc -S sqrttest.c bob@s...

Thank you - that works fine. This information is not given by 'man clang' as far as I can see. Do you have a pointer to where this (and any other useful information about clang) is documented?

Maybe true - I lifted the code from the intarwebs to avoid the "oh..it was my fault" that I usually find after detecting compiler/linker/system anomalies :oops: Changing the code to use %f in the format string does, however, not alter the fact that clang still thinks that the square root o...

I installed binutils-gold because of some problem with clang not being able to link C files. I tried compiling some haskell code with ghc and saw errors in the linker (specifically bob@sweden:~/src/project_euler/haskell$ ghc 001.hs [1 of 1] Compiling Main ( 001.hs, 001.o ) Linking 001 ... /usr/bin/l...

Given the following C code ... bob@sweden:~/src/c$ cat sqrttest.c #include <math.h> #include <stdio.h> int main(void) { double x = 4.0, result; result = sqrt(x); printf("The square root of %lf is %lf\n", x, result); return 0; } bob@sweden:~/src/c$ C code from http://en.kioskea.net/faq/4058...

I wrote http://www.fourtheye.org/armasm.shtml about ARM assembly on my SheevaPlug - but all the code works on a RPi. I do not know if this helps?

I looked a bit more here http://www.fourtheye.org/armstrong.shtml

Thanks ! I was thinking whether I can directly debug on raspbian distro. So I tried this : pi@raspberrypi ~/OSonPi/self-tried $ as -g 1_led_on.s pi@raspberrypi ~/OSonPi/self-tried $ ls 1_led_on.s 3_function 5_flashing_morse_code template 2_led_blink.s 4_timer_blink a.out test.c pi@raspberrypi ~/OSo...

I wrote an introduction to assembly language programming on the sheevaplug (which uses an ARM V5TE) at http://www.fourtheye.org/armasm.shtml . All the techniques used and code works on a Raspberry Pi too.
