I tried to pinpoint the cause of error in pmoses.cpp and reduced the
code to just a few lines:
#include "PhraseDictionary.h"
using namespace std;
using namespace Moses;
int main (int argc, char *argv[]) {
vector<FactorType> input, output;
vector<float> weight;
string filePath = "/path/to/phrase-table";
weight.push_back(1);
weight.push_back(1);
weight.push_back(1);
weight.push_back(1);
weight.push_back(1);
const PhraseDictionaryFeature* feature = new
PhraseDictionaryFeature(weight.size(), 0, input, output, filePath,
weight, 20);
}
I compile it with:
g++ -D_FILE_OFFSET_BITS=64 -D_LARGE_FILES -g -Lsrilm/lib/i686-m64
-Lirstlm/lib/x86_64 -Lmoses/moses/src/.libs -o pmoses -I.
-Imoses/moses/src pmoses.cpp -lmoses -loolm -ldstruct -lmisc -lirstlm
-lz -lboost_thread-mt
Running it I get:
> pmoses
