Question

我正在开发一个带有pocketsphinx的小程序（语音到文本 - 库）。在Windows上我使用Code :: Blocks作为开发环境，我成功构建了一个程序。现在我尝试将我的程序移植到Linux，并且我几乎没有问题链接到pocketsphinx。

这是Makefile：

CC = g++
CFLAGS = -Wall -std=c++11
LDFLAGS = -I/usr/local/include/sphinxbase -I/usr/local/include/pocketsphinx

OBJ = obj/Application.o obj/Main.o obj/Recorder.o

all: $(OBJ)
    $(CC) -L/usr/local/lib -o bin/Eve $(OBJ) -s -lsphinxbase -lpocketsphinx

obj/Main.o: src/Main.cpp
    $(CC) $(CFLAGS) $(LDFLAGS) -c src/Main.cpp -o obj/Main.o

obj/Application.o: src/Application.cpp src/Application.hpp
    $(CC) $(CFLAGS) $(LDFLAGS) -c src/Application.cpp -o obj/Application.o

obj/Recorder.o: src/Recorder.cpp src/Recorder.hpp
    $(CC) $(CFLAGS) $(LDFLAGS) -c src/Recorder.cpp -o obj/Recorder.o

与我在Windows上使用的相同，我只是调整了文件路径。

我收到以下错误：

$ make

我不认为这是name mangling问题，因为我使用提供的Makefile自行构建了lib。

如何在没有错误的情况下链接lib？

编辑：我想出了如何让它发挥作用。我只是将目标“all”的规则修改为：

$(CC) -static -L/usr/local/lib -o bin/Eve $(OBJ) -s  -lpocketsphinx -lsphinxbase -lsphinxad -lpthread

Answer 1

类似ad_read的函数在libsphinxad库中定义，您需要将它添加到链接器命令行：

g++ -static -L/usr/local/lib -o bin/Eve obj/Application.o obj/Main.o obj/Recorder.o \
-lpocketsphinx -lsphinxbase -libsphinxad

请注意，图书馆的顺序很重要。

静态链接pocketphinx（图书馆）
