./mnist_caffe: error while loading shared libraries: libarmnn.so: cannot open shared object file: No such file ordirectory

libarmnn.socode>./mnist_caffecode>libarmnn.so . actually libarmnn. So is already compiled file, the directory is /home/lg/armnnSDK armnn .
home /lg/armnnSDK/armnn <>ode>sudo />/ ldconfig <>de>/home/lg/armnnSDK/armnn sudo /sbin/ldconfig However, this is generally not done for self-compiled files, and self-compiled libraries generally use method two configuration path. export LD_LIBRARY_PATH=/home/lg/armnnSDK/armnn:$LD_LIBRARY_PATH LD_LIBRARY_PATH=/home/lg/armnnSDK/armnn:$LD_LIBRARY_PATH if this only takes effect at the current terminal.
2. Check the static library which contained in o file
ar - TV libXXX. A
3. View the static library or o what functions contained in
objdump - tT libXXX. A or objdump - tT libXXX. O
4. How to survive the static library
ar - RCS libXXX. A A.o B.o
with A.o and B.o with the following method to generate, specify the GCC -c is generated by the o file:
GCC - c - O3 A.c - i./, GCC - c - O3 biggest - i./
5. Statistical number of files and folders
in the current directory file number: the ls -l | grep "^ -" | wc -l
in the current directory. O number at the end of the file: ls -l *. O | grep "^ -" | wc -l
the current number of directories and subdirectories file: ls - lR | grep "^ -" | wc -l
in the current directory folder contains the number of folders: ls -l | grep "^ d | wc -l
number of the current folder and subfolders contained in the folder ls - lR | grep" ^ d | wc -l
6. Linux system (Linux server and Linux device, IPC, etc.) mount Windows directory
cifs mount
for embedded development tend to the source code on Windows, Compile on Linux, if you mount the Windows directory under Linux will greatly improve the development efficiency.
for IPC, serial logins IPC, into the root directory of the IPC /, in the mount point choices /MNT or /TMP , may also be other directory.
mount -t the IP address of the cifs// Windows/on Windows to the Shared folder name/MNT/hardpoints name -o username = XXX, password = XXX
for example, set up a folder in Windows' D set the win - MNT , and then set up a Shared, assuming that the IP address of the Windows is 10.182.13.58 , Mount way is:
mount -t cifs// 10.182.13.58/win - MNT/MNT -o username = garylau, password = mypasswd
for Linux system other equipment is also similar, creating good to mount the directory under Linux (mount point), Windows directory can be mounted to the Linux hardpoints.
delete mount: umount,/MNT
sometimes need to hardpoints under Linux has the authority to read not only must have the write permissions, this instruction need to add the dir_mode = 7, 77, file_mode = 0777 , namely:
mount -t the IP address of the cifs// Windows/on Windows to the Shared folder name/MNT/hardpoints name -o username = XXX, password = XXX, dir_mode = 0777, file_mode = 0777
if the mount times the following error, is due to the NFS (Network File System, a Network File System server) has multiple versions, V2, V3, V4, and all versions run at the same time, so you need to specify the version number when mounting. mount -t cifs //Windows IP address /Windows to share folder name/MNT/mount point name -o username=XXX, password=XXX, vers=2.1

mount error(121): Remote I/O error
Refer to the mount.cifs(8) manual page (e.g. man mount.cifs)

a. getconf LONG_BIT
b. uname -a
c. uname -r
d. cat /proc/version
