我已经下载的最新版本espeak-ng从GitHub，并没有./autogen.sh ./configure make make install 。 所以我写了一个测试程序，你可以看到如下：
#include <string.h>
#include <vector>
#include </usr/local/include/espeak-ng/speak_lib.h>
int samplerate; // determined by espeak, will be in Hertz (Hz)
const int buflength = 200; // passed to espeak, in milliseconds (ms)
std::vector<short> sounddata;
int SynthCallback(short *wav, int numsamples, espeak_EVENT *events) {
if (wav == NULL)
return 1; // NULL means done.
/* process your samples here, let's just gather them */
sounddata.insert(sounddata.end(), wav, wav + numsamples);
return 0; // 0 continues synthesis, 1 aborts
}
int main(int argc, char* argv[] ) {
char text[] = {"my name is espeak"};
samplerate = espeak_Initialize(AUDIO_OUTPUT_RETRIEVAL, buflength, NULL, 0);
espeak_SetSynthCallback(&SynthCallback);
espeak_SetVoiceByName("en");
unsigned int flags=espeakCHARS_AUTO | espeakENDPAUSE;
size_t size = strlen(text);
espeak_Synth(text, size + 1, 0, POS_CHARACTER, 0, flags, NULL, NULL);
espeak_Synchronize();
/* in theory sounddata holds your samples now... */
return 0;
}
并没有任何错误此命令编译它：
g++ -W -o speaks espeak.cpp -lespeak-ng
但是，当我尝试运行的可执行./speaks ，我得到这个错误信息：
./speaks: error while loading shared libraries: libespeak-ng.so.1: cannot open shared object file: No such file or directory
有什么问题？
我知道libespeak-ng.so.1是在这里： /usr/local/lib/libespeak-ng.so.1
