我必须在我的应用程序中使用 TTS 引擎，并尝试使用 Flite。我已经安装它并从命令行对其进行了测试，但是当我尝试将它放入我的应用程序时，我无法让它工作。我已经在网上搜索过但没有成功，因为大多数说明都是针对 Windows 或 android 的。我也知道 Barath-Kannan 的 c++ 包装器，但它需要 C++17，目前我无法使用它。我在 Ubuntu 16.04 上使用 C++11。

这是我的代码：

TTSFliteManager：（使用Flite的类）

#include "TTSFliteManager.h"
#include </home/user/flite/include/flite.h>
#include <utils/Logger.h>
...

void
TTSFliteManager::TTSTranslate(std::string text, std::string destination)
{
    ADD_LOG_DEBUG << "TTSFliteManager::TTSTranslate()";
    cst_voice *voice;
    flite_init();

    voice = flite_voice_select(NULL);

    float secs = flite_text_to_speech(text.c_str(),voice,destination.c_str());
    if (secs == 0)
        ADD_LOG_ERROR << "TTSFliteManager::TTSTranslate() ERROR GENERATED AUDIO FILE IS EMPTY";
    
}
...

我在构建时遇到的错误如下：

...
libPlugin.so: undefined reference to "flite_voice_select"
libPlugin.so: undefined reference to "flite_text_to_speech"
libPlugin.so: undefined reference to "flite_init"
collect2: error: ld returned 1 exit status

查看文档中的示例，我了解到我的项目中缺少一些库（“-lflite_cmu_us_kal”“-lflite_usenglish”“-lflite_cmulex”“-lflite”“-lm”）。

我应该使用“find_package”吗？“包括目录”？如果是这样，让它工作的正确参数是什么？我使用的那些（Flite，FliteDll）返回了一个错误，表明找不到这样的包。

我相信我需要正确配置 CMakeLists，但我不知道在那里写什么让项目看到 flite 库。

这个库不附带 pkg-config 文件或 CMake 支持，但它使用常规的 autotools 安装结构（PREFIX/include、PREFIX/lib）。

这意味着您可以告诉 CMake 搜索它：

find_path(FLITE_ROOT flite/flite.h PATH_SUFFIXES include)

add_library(FLite INTERFACE IMPORTED)
target_include_directories(FLite INTERFACE ${FLITE_ROOT}/include)
target_link_directories(FLite INTERFACE ${FLITE_ROOT}/lib)
target_link_libraries(FLite INTERFACE -lflite_cmu_us_kal -lflite_usenglish -lflite_cmulex -lflite -lm)

此块include/flite/flite.h在您的 CMake 搜索路径中找到并使用该路径填充 FLITE_ROOT 变量。然后我们创建一个 IMPORTED INTERFACE 目标，该目标设置有正确的头文件路径、库路径和链接库。FindFLite.cmake如果您想使其可重用，上述内容通常会包含在内，但现在您可以将其留在您的 CMakeLists.txt 中。

最后，将您自己的目标与此 CMake 目标链接：

target_link_libraries(Plugin PUBLIC FLite)

第一次运行 CMake 时，您可能需要CMAKE_PREFIX_PATH指向/home/user/flite.

编辑：将 SHARED IMPORTED 更改为 INTERFACE IMPORTED。前者希望找到一个 libFLite.so，而我已经指定了所有库依赖项。
