1.将DobotDll/Precompiled/Linux/DobotDll目录下的下面的文件拷贝到DobotDemoForPython目录下
libDobotDll.so.1.0.0,
libQt5Core.so.5.4.0,
libQt5Network.so.5.4.0
ibQt5SerialPort.so.5.4.0
2.DobotDllType.py的load()部分修改：
def load():
if platform.system() == “Windows”:
return CDLL(“DobotDll.dll”, RTLD_GLOBAL)
elif platform.system() == “Darwin”:
return CDLL(“libDobotDll.dylib”, RTLD_GLOBAL)
elif platform.system() == “Linux”:
return CDLL(“libDobotDll.so.1.0.0”, RTLD_GLOBAL)
3.执行时出现下面的错误：
$ python DobotControl.py
Traceback (most recent call last):
api = dType.load()
File “/home/root/workspace_outan/dobotdemo/DobotDemoForPython/DobotDllType.py”, line 430, in load
return CDLL(“libDobotDll.so.1.0.0”, RTLD_GLOBAL)
File “/usr/lib/python2.7/ctypes/
init
.py”, line 365, in
init
self._handle = _dlopen(self._name, mode)
OSError: libDobotDll.so.1.0.0: cannot open shared object file: No such file or directory
有什么解决办法没有？
系统信息如下：
pi@raspberrypi:~$ uname -a
Linux raspberrypi 4.4.38-v7+
#938
SMP Thu Dec 15 15:22:21 GMT 2016 armv7l GNU/Linux
执行 python DobotControl.py时即出现最上面的erro。
我就是想在这个raspberry pi 3中执行 python demo.
有什么解决办法呢？
是不是可以不用用编译好的.so文件(/DobotDll/Precompiled/Linux/DobotDll),
而用/SourceCode/DobotDll/src的文件自己编译呢？
编译的命令可以告诉我么？
我不知道生成下面的四个文件，都各自需要哪些source文件。
libDobotDll.so.1.0.0,
libQt5Core.so.5.4.0,
libQt5Network.so.5.4.0
ibQt5SerialPort.so.5.4.0
Thank you for your response.
You have to install Qt or try to get the lib file by extracting the file in a Qt folder.
pi@raspi-outan1:~/workspace/dobotdemo/DobotDemoForQt/Output $ lsal

But the Dll doen’t work in Raspberry Pi because it use a ARM architecture
⇒You mean I can use those lib files in Qt folder in Non RaspberryPI(non ARM architecture),
but those lib files do not work in Raspberry Pi?
Is any other way to run python demo in RaspberryPi?
for example compile from source code by myself?
