[Solved] Error: error C2601: ‘b‘ : local function definitions are illegal error C2063: ‘b‘ : not a function

Scene:

In general, this problem may be that a "}" is missing
There is also a small probability that your C++standard library is C++98 or earlier, which does not support non built-in initialization list writing.

the Situation of Missing ‘}’

We can see that if our test1 method is short of one}, all subsequent functions will report errors. We need to check it carefully

Solution
Check for yourself that the first line of code near the line number that reports the error is missing a }.

C++ standard does not support
When your C++ standard is C++98, the initialization list of C++98 does not support the initialization list methods of non-built-in types. This can be seen in the following code

#include <iostream>
#include <vector>
#include <map>
using namespace std;

int main()
{
	int a[] = { 1, 2, 3 };

	int b[] {1, 2, 3};
	vector<int> v{1,5,5};
	map<int, float> m{{1, 2.f}, {2, 3.2f}};

	return 0;
}

编译结果：

Solution:
Then in this case your non-built-in type variables will have to be initialized using other methods

[Solved] Error:E0415 no suitable constructor exists to convert from “int“ to “Rational“

Scene:

The problem is that the constructor for is missing or is declared as explicit.

Please refer to the following scenario.

#include <iostream>

using std::cout;
using std::endl;

class Rational1
{
public:
	Rational1(int n = 0, int d = 1):num(n), den(d)
	{
		cout << __func__ << "(" << num << "/" << den << ")" << endl;
	}

public:
	int num; 
	int den;
};

class Rational2
{
public:
	explicit Rational2(int n = 0, int d = 1) :num(n), den(d)
	{
		cout << __func__ << "(" << num << "/" << den << ")" << endl;
	}

public:
	int num;
	int den;
};

void Display1(Rational1 r)
{
	cout << __func__ << endl;
}

void Display2(Rational2 r)
{
	cout << __func__ << endl;
}


int main()
{
	Rational1 r1 = 11;
	Rational1 r2(11);
	Rational2 r3 = 11; // error E0415
	Rational2 r4(11);

	Display1(1);
	Display2(2); // error  E0415
	return 0;
}

Explicit keyword

1. Specifies that the constructor or conversion function (from C++11) is explicit, that is, it cannot be used for implicit conversion and copy initialization
2. Explicit can be used with constant expressions The function is explicit if and only if the constant expression evaluates to true (From C++20)

Problem description

Error:E0415 no suitable constructor exists to convert from “int“ to “Rational“

Solution:

1. Implement the corresponding constructor yourself. (Recommended)
2. Delete the constructor modified by the explicit keyword. (Not recommended)

[Solved] error C2041: illegal digit ‘9‘ for base ‘8‘ | error C2059: syntax error: ‘bad suffix on number‘

Error log

Text

Octal value is out of range

Hexadecimal value is out of range

1> Done building project “test12.vcxproj” – FAILED.

Screenshot (hexadecimal value exceeds the range)

Solution:

C2041 series error: this kind of number, which is generally octal or hexadecimal, is out of range
for example:

  1. 09; because there is no 9 in octal
  2. 0xq; because hex doesn’t have the q character.

This requires us to carefully check whether the relevant figures exceed the range.

[Solved] C++ Compile Error: prerequisites are different [How to Solve]

Scene

When adding new x.h/x.hpp/X.C/x.cpp files to the UE4 project, even if there are no other files to include these new files, the following errors may appear during compilation (both build and rebuild):
unrealbuildtool prerequisites are different
this error occurs when the x.obj file is compiled, but the link operation cannot be performed correctly

reason

As the name suggests, there is no problem with the code itself, but that the code block cannot be integrated into the existing project. UE4 has preprocessing on the path for the include file. If the path name of the file is duplicate, this problem will occur. For example:

1. Proto/error.pb.h already exists under module 

2. try to add Server/XXServer/proto/error.pb.h

According to the include rule of UE4, #include "proto/error.Pb.H" may point to two files at the same time (when the files in the server/xxserver directory are imported), so it cannot be judged accurately, and an error is reported during compilation.

Note: unrealbuildtool under Windows does not judge case, and the paths of proto/and proto/are the same

Solution:

    directory paths should not overlap. Try to avoid the path with the same name.
    1. There should be no files with the same name under the path

[Solved] PYNQ load bit error: KeyError: ‘interrupts‘

Problem Description:

In the BD diagram of vivado, the interrupted direct connection between my IP and PS Core

An error occurs when loading the bit file generated by vivado in pynq

Solution:

Add a concat block in the connection between PS and our own IP interrupt line, as shown in the figure below

finally, the bit file can be successfully loaded in pynq

and the final program can output correct results
