This article shares from Huawei cloud community “Embedded Linux under the transplantation of Samba services –” based on beidou and 4G CAT1 module of intelligent logistics “development combat, author: Small orange.
Samba is a piece of free software that implements the SMB protocol on Linux and UNIX systems. It consists of server and client programs. Server Message Block (SMB) is a communication protocol for sharing files and printers on a LAN. SMB provides file and printer sharing services between different computers on a LAN.
Embedded development process, often need to transfer the file to the development board, after the transplantation of Samba service, the development board will be connected to the LOCAL area network, can directly access the development board through the IP address of the development board directly access the development board Samba shared folder, in the development board and the LOCAL area network file transfer is convenient and fast. This article focuses on porting Samba and the problems you may encounter during development.
Thanks to the STM32MP1 development board provided by Huawei Cloud IoT course “Intelligent Logistics Based on Beidou and 4G CAT1 module”, you can pay attention to Huawei cloud public account, Huawei cloud IoT Forum for more activities.
The development environment
System: Ubuntu 18.04 64-bit
Development board: STM32MP157
Samba version: 3.2.15
The preparatory work
The samba download links: download.samba.org/pub/samba/
Select Samba-3.2.15.tar. gz to download.
compile
After the download is complete, run the tar command in the folder to decompress the package. After the package is decompressed, go to the samba-3.2.15/source folder for configuration.
The tar - VXF samba - 3.2.15. Tar. GzCopy the code
Edit and modify the configure file after entering the folder. The modification contents are as follows. There are seven modifications in the whole text.
Original content:
echo "$as_me: error: cannot run test program while cross compiling See \`config.log' for more details." >&2; } { (exit 1); exit 1; }; }Copy the codeInstead of
$as_echo "$as_me: error: cannot run test program while cross compiling See \`config.log' for more details." >&2; } # { (exit 1); exit 1; }; }; }Copy the codeSee the following figure after modification
Run the following command
echo SMB_BUILD_CC_NEGATIVE_ENUM_VALUES=>arm-linux.cache
./configure CC=arm-none-linux-gnueabihf-gcc LD=arm-none-linux-gnueabihf-ld AR=arm-none-linux-gnueabihf-ar --target=arm-none-linux --host=arm-none-linux-gnueabihf samba_cv_CC_NEGATIVE_ENUM_VALUES=yes --cache-file=arm-linux.cache
Copy the code
The configuration is complete.
After configuration, execute make command to compile, as shown in the following figure:
After compiling, run make install to install. The default installation path is /usr/local/samba.
Install /usr/local/samba and copy it.
tar -vcf samba.tar.gz samba/
Copy the codeAfter the package is complete, copy the samba.tar.gz file to the /usr/local folder on the development board. Copy the SCP command to the development board (the development board has been connected to the LAN and can be pinged to each other by the Ubuntu system, the IP address of the development board is 192.168.124.11), and the command is as follows:
SCP samba - 3.2.15. Tar. Gz [email protected]: / usr/localCopy the codeAfter the package is sent, you can view it in /usr/local on the development board. Run the following command to decompress the package:
tar -vxf samba.tar.gz
Copy the codeGo to the /usr/local/samba/lib folder and add the smb.conf file. The configuration file can be configured as required.
Add the following:
[global]
workgroup = WORKGROUP
server string = samba sever
netbios name =myarm
guest account=root
security =share
interfaces = eth0
[share]
component = share dir
path = /opt/
guest ok=yes
browseable=yes
public = yes
directory mask = 0777
create mask = 0777
available = yes
Copy the codeAfter adding the smb.conf file, go to the samba/bin file to test it and run the./findsmb file. You can search for the Samba server on the LAN.
Access the samba/sbin folder and run commands to enable the Samba service.
./smbd -D
./nmbd -D
Copy the code
At this point, samba service transplantation is complete, you can open “run” in Windows shortcut win+ R, input development board development board IP access development board shared folder, mom no longer need to worry about the file transfer problem!
An error occurred during compilation
Checking that the C Compiler recognizes negative enum values… configure: error

Solutions:
Run the following command and add parameters to the./configure command: –cache-file=arm-linux.cache

Solutions:
Edit And modify the contents of the configure file as follows. There are seven modifications in the whole document.
Original content:
echo "$as_me: error: cannot run test program while cross compiling See \`config.log' for more details." >&2; } { (exit 1); exit 1; }; }Copy the codeInstead of
$as_echo "$as_me: error: cannot run test program while cross compiling See \`config.log' for more details." >&2; } { (exit 1); exit 1; }; }; }Copy the codeThe change is shown below
