我试图安装teradeep/demo-apps进行试验，但遇到了障碍。

打开包装后，我看到了三个文件夹：opencv、generic-pc和generic-embedded. 编译这两个通用文件夹后，我尝试运行所有三个，但三个都失败了。

当我尝试运行generic-pc时，它给了我：

    ./frame.lua:63: in function 'prep_lua_linuxcamera'
    ./frame.lua:86: in function 'init'
    run.lua:102: in main chunk

当我尝试运行opencvandgeneric-embedded文件夹时，它给了我：

: error while loading shared libraries: libthnets.so: cannot open shared object file: No such file or directory

解决此问题的最佳方法是什么？

为了在 linux 上正常工作，演示应用程序需要一个专门编译的库，称为linuxcamera演示应用程序提供的库。您将需要编译它并将其存储在您的/home/dave/torch/install/lib/lua/5.1/文件夹中。

首先，转到lib文件夹generic-pc并编辑Makefile文件，使其看起来像这样（您可以复制并替换所有内容，唯一更改的是 libs 文件夹的路径）：

UNAME_S := $(shell uname -s)
UNAME_P := $(shell uname -p)
LBITS := $(shell getconf LONG_BIT)

INCLUDE = -I. -I/usr/local/include -I$(HOME)/torch/install/include
LIBOPTS = -shared -L$(HOME)/torch/install/lib/lua/5.1 -L$(HOME)/torch/install/lib
CFLAGS = -O3 -c -fpic -Wall
LINUXCAMERA_FILES = linuxcamera.o videocap.o
LIBFILES = linuxcamera.so
CC = gcc

ifneq ($(filter arm%,$(UNAME_P)),)
    CFLAGS += -mfpu=neon
endif

.PHONY : all
all : $(LIBFILES)

.c.o:
    $(CC) $(CFLAGS) $(INCLUDE) $<

linuxcamera.so : $(LINUXCAMERA_FILES)
    $(CC) $(LINUXCAMERA_FILES) $(LIBOPTS) -o $@

install : $(LIBFILES)
    sudo cp $(LIBFILES) $(HOME)/torch/install/lib/lua/5.1/

uninstall :
    sudo rm $(HOME)/torch/install/lib/lua/5.1/linuxcamera.so

.PHONY : clean
clean :
    rm -f *.o $(LIBFILES)

然后，如记录的那样，运行make clean; make; make install;

这应该为您的运行时编译并复制lib文件夹中的库。qlua您现在应该能够运行qlua run.lua并且它应该正确加载库。
