Wraping up OpenJtalk in Go, files are successfully included and types are referenced without an issue, but functions trigger an undefined reference error.
jtalk.go:
package main
// #cgo CFLAGS: -I/home/vagrant/open_jtalk/njd [...etc]
/*
#include <stdio.h>
#include <stdlib.h>
#include <stdarg.h>
#include <string.h>
#include <math.h>
// Main headers
#include "mecab.h"
#include "njd.h"
#include "jpcommon.h"
#include "HTS_engine.h"
// Sub headers
#include "text2mecab.h"
#include "mecab2njd.h"
#include "njd_set_pronunciation.h"
#include "njd_set_digit.h"
#include "njd_set_accent_phrase.h"
#include "njd_set_accent_type.h"
#include "njd_set_unvoiced_vowel.h"
#include "njd_set_long_vowel.h"
#include "njd2jpcommon.h"
*/
import "C"
type Open_JTalk struct {
mecab C.Mecab each of these struct references are fine
njd C.NJD
jpcommon C.JPCommon
engine C.HTS_Engine
}
func (open_jtalk *Open_JTalk) Open_JTalk_initialize() {
C.Mecab_initialize(&open_jtalk.mecab) // when any function is called the error happens
C.NJD_initialize(&open_jtalk.njd)
C.JPCommon_initialize(&open_jtalk.jpcommon)
C.HTS_Engine_initialize(&open_jtalk.engine)
}
func main() {
}
And the weird part is that those same functions are declared right after the types:
mecab.h
// line 1584
typedef struct _Mecab{
char **feature;
int size;
mecab_t *mecab;
} Mecab;
BOOL Mecab_initialize(Mecab *m);
