Dear mailing list,<br>
<br>
For a project I am working on speeding up a simulation in R by<br>
translating it to C++ (using inline and Rcpp). It is done and works fine<br>
on my windows 7 64bit R, but for some reason it is not working on my<br>
supervisors latest mac OSX (not sure of the version. should be up to date).<br>
<br>
The strange thing is that it did work at first. It compiled and ran as<br>
expected. We then proceeded by changing a few things, resulting in the<br>
function not compiling anymore. When we then used exactly the same<br>
script as before it suddenly did not work anymore. I get these errors:<br>
<br>
<br>
Error in compileCode(f, code, language = language, verbose = verbose) :<br>
Compilation ERROR, function(s)/method(s) not created!<br>
file345af547.cpp: In function ‘SEXPREC* file345af547(SEXPREC*, SEXPREC*,<br>
SEXPREC*, SEXPREC*, SEXPREC*, SEXPREC*)’:<br>
file345af547.cpp:220: error: ISO C++ says that these are ambiguous, even<br>
though the worst conversion for the first is better than the worst<br>
conversion for the second:<br>

In addition: Warning message:<br>
running command '/Library/Frameworks/R.framework/Resources/bin/R CMD<br>
SHLIB file345af547.cpp 2> file345af547.cpp.err.txt' had status 1<br>
<br>
With relevant lines:<br>
<br>
220 : Demoplayers = Demoplayers - 1;<br>
<br>
646 : leeftijd = leeftijd + 1;<br>
<br>
Demoplayers and leeftijd are both NumericVectors. Does anyone know if<br>
there is a common bug on MacOSX that for some reason makes the inline<br>
compiler not work anymore? The cxxfunction example works fine though.<br>
<br>
Best,<br>
Sacha<br>
