Unable to build AllJoyn JS Bindings & Compiler too old to build AllJoyn when building for Android - alljoyn
This is how I set up AllJoyn:
cd /opt
sudo mkdir alljoyn
sudo chown -R danny:danny alljoyn
cd alljoyn
repo init -u https://git.allseenalliance.org/gerrit/devtools/manifest.git
repo sync
repo start master --all
Now, I would like to build AllJoyn js bindings, but getting Exceptions (c, cpp and java worked out of the box):

scons: *** [build/linux/x86_64/debug/obj/alljoyn_js/jni/ProxyBusObjectHost.os] Error 1
scons: building terminated because of errors.
And when trying to build AllJoyn on Linux for my Android device it complains the compiler is too old:
/opt/alljoyn/core/alljoyn$ scons OS=android CRYPTO=builtin ANDROID_NDK=/opt/android-ndk-r13
scons: Reading SConscript files ...

*** Compiler too old to build AllJoyn. Aborting.
I'm using the following compiler versions:
$ gcc --version

I'm really confused as from above the c++ compiler should have support for -std=c++11 flag.
Notice: I've downloaded NDK r13 and had to create /opt/android-ndk-r13/RELEASE.TXT which contains r13a in order to pass the version check.
List of /opt:
$ ls /opt
alljoyn android-ndk-r13 android-sdk-linux android-studio xulrunner-sdk
And btw: Setting up and building AllJoyn is a mess. Docs are outdated and contradictory.
--Answer not related to the main topic-- I agree the documents are sometimes very confusing, and now since the merger is on the way there will be more cases of Documents being even more less updated.

R use stats::optimize in Rcpp, simple example fails to compile
I want to use the R stats::optimize function in Rcpp because I haven't been able to find an Rcpp equivalent. The code below is my attempt at a simple example based on the Example in the optimize help, but fails.
Here's the R function and results
f <- function (x) (x - .33)^2
xmin <- optimize(f, c(0, 1), tol = 0.0001)
xmin
This returns
$minimum
[1] 0.333
$objective
[1] 0
Here's the Rcpp code that fails when sourcing it.
#include <Rcpp.h>
const double tolerance = 1e-0;
// [[Rcpp::export]]
Rcpp::NumericVector f(Rcpp::NumericVector x) {
return pow(x-0.33, 2);
}
Rcpp::List fTg_opt(const double optmin, const double optmax) {
Rcpp::Environment base("package:stats");
Rcpp::Function optimize_r = base["optimize"];
Rcpp::NumericVector interval = {optmin,optmax};
return optimize_r(f, interval, tolerance);
}
The Rstudio console has the following error messages.

Error in Rcpp::sourceCpp("R/cpp/testopt.cpp") :

One of your problems here is that you assume that becomes a function you submit to compilation under Rcpp::sourceCpp() is callable under its exported name.
It is not. Try Rcpp::sourceCpp(..., verbose=TRUE), i.e. add that arguments, to see what is really called. Those you could pass around (using SEXP argunments and results, but they are unwieldy).
To prove, here is a 'working but useless' version of your code. If we pass f() from R too, everything is callable.
Morale: The interface still is SEXP .Call("name", SEXP a, SEXP b, ...) even if Rcpp hides that. No Free Lunch (TM). But as my comment hinted, there are optimization packages you can use with Rcpp.
Code
#include <Rcpp.h>
// [[Rcpp::export]]
Rcpp::List fTg_opt(Rcpp::Function f, const double optmin, const double optmax) {
Rcpp::Environment base("package:stats");
Rcpp::Function optimize_r = base["optimize"];
Rcpp::NumericVector interval = {optmin,optmax};
Rcpp::List res = optimize_r(f, interval);
return res;
}
/*** R
f <- function (x) (x - .33)^2
xmin <- optimize(f, c(0, 1), tol = 0.0001)

(M68k) Why is my value not getting passed into D0?
So I am writing a program and subroutine where this is basically the pseudocode.
int findmin(int* vals, int count){
if(count == 1){
return vals[0];
}else{
int minrest = findmin(vals+1,count-1);
if (minrest < vals[0]){
return minrest
}else{
return vals[0]
}
}
}
I basically have to put this into m68k assembly code. In the pictures is what i have so far. I think my logic is correct but for some reason all this does is printout my header and nothing else, I feel like for some reason I am not corectly storing my result into D0 where it should be. Is there a step I am missing or something that I am just completely off on? My prog4.s is my main that calls the subroutine
My prog4.s is my main that calls the subroutine
subroutine recursive function
The main code calls the subroutine like this: pea vals move.w D1, -(SP) jsr findmin adda.l #6, SP The findmin subroutine makes next recursive call: move.l A0, -(SP) move.w D1, -(SP) jsr findmin adda.l #6, SP The findmin subroutine retrieves its parameters like: findmin: link A6, #0 ... move.w 8(A6), D1 move.l 12(A6), A0 <<< Here is the error! But wait, because of how you placed things on the stack, this is how the stack is laid out: A6 RTS D1 A0 lower ==== ==== == ==== higher ^ SP == A6 The above shows that the word D1 is at 8(A6) and that the longword A0 is at 10(A6). That's 10 instead of 12.

You need the libgfortrain-$VERSION-dev package for your machine. At some point having gfortran implied this via r-base-dev and its dependence on build-essentials.
Edit: Version numbers will of course be different on your 12.04 release; this was from a machine running 13.10.
Edit 2, based on your update: Your use of sourceCpp() is incorrect. You are not telling Rcpp that you need Armadillo, so Rcpp responds by saying it does not know Armadillo. You can either use a Rcpp::depends() in the cpp file, or use the plugin= argument.
So here is how I would write the code you have above. You can then just call sourceCpp() on the file which will create a function rcppSim() you can call:
#include <RcppArmadillo.h>
// [[Rcpp::depends(RcppArmadillo)]]
// [[Rcpp::export]]
arma::mat rcppSim(arma::mat coeff, arma::mat errors) {
int m = errors.n_rows;
int n = errors.n_cols;
arma::mat simdata(m,n);
simdata.row(0) = arma::zeros<arma::mat>(1, n);
for (int row=1; row < m; row++) {
simdata.row(row) = simdata.row(row-1)*trans(coeff) + errors.row(row);
}
return simdata;

Armadillo: solve with sp_mat
I'm writing a basic FEM program using Armadillo. I use sp_mat and vec as matrix and vector type. The problem is, that when I do solve(X, b) i get an error. Could it be that solve does not support sp_mat. Any alternatives except of using dense matrices? Below is the code, where the sp_mat doesn't compile. If I use the the commented line mat A instead it works fine.
int N = 3;
double h = 1./N;
//mat A = zeros<mat>(N+1,N+1);
sp_mat A(N+1,N+1);
for(int i=0;i<=N;i++) {
if(i>0) {A(i,i-1)=-1.;}
A(i,i)=2.;
if(i<N) {A(i,i+1)=-1.;}
}
A(N,N)=1;
vec b = zeros(N+1);
for(int i=0;i<=N;i++) {
b(i)=h;
}
vec zeta = solve(A,b);
cout << zeta;

Sparse matrix support in Armadillo is not yet complete. You can use ARPACK for (eigen-)decomposition of sparse matrix. Sparse matrix solvers will probably comes in the next release which may use the CXSparse library from the SuiteSparse project.
As of version 5.0, Armadillo has the spsolve() function for solving sparse systems.
