gcc undefined reference

我在跑..

gcc -c -I/usr/vt/sample ttssample.c
gcc -L. -lttsapi ttssample.o -o ttsample

我收到以下错误...

ttssample.o: In function `_TTSFile':
ttssample.c:(.text+0x352): undefined reference to `TTSRequestFile'

collect2: ld returned 1 exit status

和TTSRequestFile在lib header 中，但它的前面有DllExport，我想知道这是我的错误的原因吗？任何帮助，不胜感激。

DllExport int TTSRequestFile(char *szServer, int nPort, char *pText, int nTextLen, char *szSaveDir, char *szSaveFile, int nSpeakerID, int nVoiceFormat);

最佳答案

您的链接命令是错误的。库应在命令末尾指定:

gcc ttssample.o -o ttsample -L。 -lttsapi
