Openfstexample.cpp:1:24:致命错误:fst/fstlib.h:没有终止这样的文件或目录编译

Question

我正试图在Ubuntu 1004 中使用gcc编译以下代码

#include <fst/fstlib.h>
namespace fst {
  // Reads in an input FST. 
  StdVectorFst *input = StdVectorFst::Read("input.fst");
  // Reads in the transduction model. 
  StdVectorFst *model = StdVectorFst::Read("model.fst");
  // The FSTs must be sorted along the dimensions they will be joined.
  // In fact, only one needs to be so sorted.
  // This could have instead been done for "model.fst" when it was created. 
  ArcSort(input, StdOLabelCompare());
  ArcSort(model, StdILabelCompare());
  // Container for composition result. 
  StdVectorFst result;
  // Creates the composed FST. 
  Compose(*input, *model, &result);
  // Just keeps the output labels. 
  Project(&result, PROJECT_OUTPUT);
  // Writes the result FST to a file.
  result.Write("result.fst");
}

它给出以下错误

Openfstexample.cpp:1:24: fatal error: fst/fstlib.h: No such file or directory
compilation terminated.

请注意，我已经从安装了Openfsthttp://www.openfst.org/

有线索吗？

编译时需要链接openfst库。

尝试：

gcc -lfst <filename>

[确保在/usr/local/lib]中安装了库

或尝试：

gcc -L /usr/local/lib/libfst.dylib <filename>
