问题
I have downloaded the last version of espeak-ng
from github, and did ./autogen.sh ./configure make make install
.
so I wrote a test program as you can see below:
#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;
}
And compiled it by this command without any errors:
g++ -W -o speaks espeak.cpp -lespeak-ng
But when I try to run the executable by ./speaks
, I get this error message:
./speaks: error while loading shared libraries: libespeak-ng.so.1: cannot open shared object file: No such file or directory
What's the problem?
I know libespeak-ng.so.1
is here: /usr/local/lib/libespeak-ng.so.1
回答1:
I solved the problem by adding these two lines to my `/etc/environment' file:
LD_LIBRARY_PATH=/usr/local/lib
PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
回答2:
On Ubuntu 18.04 this is caused by setting the wrong path for the library.
You can fix it by: sudo ln -s /usr/local/lib/libespeak-ng.so.1 /usr/lib/libespeak-ng.so.1
