The reason for the problem is that a variable is declared in a header file, but it is defined in two or more. CPP files.
Solution: generally, the compiler will tell you which variable has a problem. You need to locate the variable, and then delete one of the redundant variable definitions
There is also a helpless solution. You can open the project configuration properties connector command line and enter the following string to allow multiple settings:
/ force:multiple
Incompatible with lower version. Add the following version or lower version
npm install –save-dev [email protected] less ( Add less (lower version)
The SSH connection of xshell frequently prompts socket error event: 32 error: 10053
1. Cancel the check at the tunnel
2 modify/etc/SSH/sshd_ Configuration file under config
Change the value of clientaliveinterval to 60
Then restart the ssh server
At present, there is no frequent SSH disconnection problem, which should be effective
When encountering the error: strain ‘,’241’,’343 ‘in program
An error is a compilation error in C/C + +.
The error refers to the source program has illegal characters, illegal characters need to be removed. Generally, the coder uses Chinese input method or directly copies and pastes the code from other places. Chinese space, Chinese quotation marks and various Chinese punctuation marks appear in the code.
Solution:
open the error file in Notepad and save it in ANSI format. You can see that some unrecognized characters become garbled.
1. Delete the space in the wrong line and the space before and after it, and try again
2. Change the color that is obviously different from other punctuation marks（ Most compilers have color recognition)
3. If the code is relatively short, it is recommended to re type it all

Using the above method, we should show the main function in rnx2rtkp. C, otherwise it will conflict with the external main function
In addition, the compiler must
Modify rtklib. H and add
?Define envelope
#define ENAGAL
#define ENACMP
#define ENAQZS
#define ENAIRN
Otherwise
When the convrnx function finishes executing, exits the dynamic library and returns to the main function, the “run time check failure # – 2 – stack around the variable ‘opt #” pop up in debug mode Is abnormal. The exception does not pop up in release mode. On the network about this exception, the main body thinks that it is caused by memory out of bounds, and the author has not found out opt yet_ The reasons of variable out of bounds will be further studied in the future. “Project – & gt; Configuration properties – & gt; c/c+ ±& gt; Code generation – & gt; The basic runtime check can be changed to the default value.

On the Mac computer, compile the code of golang. After the code is successfully compiled, execute it. An error is reported
exec format error
After a long time of investigation, I finally found the problem: my computer’s configuration of golang is as follows:
GOOS="linux"
After compiling, I run it on MacOS, so I report an error.
When you know where the problem is, it’s very easy to solve it. When compiling, the execution is as follows:
GOOS=darwin GOARCH=amd64 go build -o http -v ./main.go
About installing SQL server 0 in Windows 10 20h2 × 84bb0001 is one of the solutions
Background solutions
Background
A brand new computer, upgrade to 20h2, and want to install a SQL Server 2005, the result is an error “try to execute unauthorized operation, error code 0 × 84BB0001”
resolvent
Those problems on the Internet, such as uninstalling and completely re installing, are different from those I encountered, but the way to report errors is the same. Let’s draw a conclusion directly
Edge fuckin ‘! No updates!!!!! After updating edge, it will be ready. Please refer to the details https://docs.microsoft.com/en-us/answers/questions/148323/windows-10-version-20h2-install-error-code-0x84bb0.html
