r - Rcpp - Compile a C++ file with multiple functions -

-

i have quick question how compile .cpp file multiple function in it. let's have c++ file : functions.cpp

#include <rcpp.h> #include <math.h>       /* pow */ using namespace rcpp;   // [[rcpp::export]]  int function1 (int n, numericmatrix w){  return ....   }   // [[rcpp::export]]  int function2 (int n, numericmatrix w){  return ....   }

and compile file , able to call both functions. have done it, happens when try load functions.o gives me this":

 error in indl(x, as.logical(local), as.logical(now), ...) :  unable load shared object 'c:/users/functions.o':   loadlibrary failure:  %1 not valid win32 application.

anybody , idea ?

just use sourcecpp("nameofyourfile.cpp")

if you have no syntax error preventing compilation both function1 , function2 accessible in r session.

literally thousands of such files have been written, , 1 hundred @ disposal on @ the rcpp gallery.

Qt4: how to send QString inside a struct via QSharedMemory -

-
i have struct struct control_data{ int column_number; qstring cell; }; i need send thread of qsharememory. read can't because qstring contains pointers inside. other ways? you have serialize struct byte array. can convert qstring const char* this: mystring.tostdstring().c_str(); but serializing qstring should work. the first step serialize struct qdatastream using qt, example here . then once struct can read , written can pass shared memory. a complete example of using qsharedmemory can found here . here relevant code: // first, test whether shared memory segment attached process. // if so, detach if (sharedmem.isattached()) { sharedmem.detach(); } ... qbuffer buffer; buffer.open( qbuffer::readwrite ); qdatastream out( &buffer ); out << youstruct; int size = buffer.size(); // size of int + size of qstring in bytes if ( !sharedmem.create( size ) ) { return; } // write shared memory sharedmem.lock(); char *to = (char*...

python - jinja2: TemplateSyntaxError: expected token ',', got 'string' -

-
i new jinja2 , having issue using python regular expression (re). in following code bold lines have error string in them. {% block content %} <div class="container"> {% l in lines %} {% if re.search(r"error", l) %} {# <<< throws error #} <b> {{ l }} </b> {% else %} {{ l }} <hr> {% endif %} {% endfor %} </div> {% endblock %} the re.search above throws following error: jinja2.exceptions.templatesyntaxerror templatesyntaxerror: expected token ',', got 'string' raw python code not supported in jinja2 template syntax. {% if re.search(r"error", l) %} replace line with {% if "error" in l %} can fix problem. if logical condition more complicated, should consider defining own custom filters (which can call python code) or complicated things in view layer. go check global namespace .
