Compilation error expected primary expression before token

This code compiles and works as expected (it throws at runtime, but never mind): #include #include void foo(boost::property_tree::ptree &amp...

This code compiles and works as expected (it throws at runtime, but never mind):

#include <iostream>
#include <boost/property_tree/ptree.hpp>

void foo(boost::property_tree::ptree &pt) 
{
    std::cout << pt.get<std::string>("path"); // <---
}

int main()
{
    boost::property_tree::ptree pt;
    foo(pt);
    return 0;
}

But as soon as I add templates and change the foo prototype into

template<class ptree>
void foo(ptree &pt)

I get an error in GCC:

test_ptree.cpp: In function ‘void foo(ptree&)’:
test_ptree.cpp:7: error: expected primary-expression before ‘>’ token

but no errors with MSVC++! The error is in the marked line <---. And again, if I change the problem line into

--- std::cout << pt.get<std::string>("path"); // <---
+++ std::cout << pt.get("path", "default value");

the error disappears (the problem is in explicit <std::string>).

Boost.PropertyTree requires Boost >= 1.41. Please help me to understand and fix this error.

Starting Context

  • The reader has a basic knowledge on C++.

Target Context

  • The reader will know how to solve an «expected primary-expression before ‘» «>» or whatever «‘ token» C++ GCC compile error.

Orientation

There is an article that clarifies the concept of template in C++.



There is an article that clarifies the distinction between definition and declaration in C++.



Main Body

1: Meeting an «expected primary-expression before ‘>’ token» C++ GCC Compile Error


Hypothesizer 7

«expected primary-expression before ‘>’ token»? What is that supposed to mean? . . .



Well, I am trying to compile this piece of C++ code with GCC (note that I put function template body declarations (which should not be called «definitions») into ‘tpp’ files).

				    ClassE ();
				    virtual ~ClassE ();
					template <typename U> U methodE0 (U const & a_argument0) const;
			};
		}
	}
}

namespace theBiasPlanet {
	namespace coreUtilitiesTests {
		namespace templatesTest1 {
			ClassE::ClassE () {
			}
			
			ClassE::~ClassE () {
			}
		}
	}
}



theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassE.tpp




@C++ Source Code

#include "theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassE.hpp"

namespace theBiasPlanet {
	namespace coreUtilitiesTests {
		namespace templatesTest1 {
			template <typename U> U ClassE::methodE0 (U const & a_argument0) const {
				return a_argument0;
			}
		}
	}
}



theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassF.hpp

						template <typename U> static void methodF0 (U const & a_argument0);
						static void methodF1 (ClassE const & a_argument0);
				};
			}
		}
	}
#endif



theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassF.cpp




@C++ Source Code

#include "theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassF.hpp"

#include <string>

namespace theBiasPlanet {
	namespace coreUtilitiesTests {
		namespace templatesTest1 {
			void ClassF::methodF1 (ClassE const & a_argument0) {
				a_argument0.methodE0 <std::string> ("aaa");
			}
		}
	}
}



theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassF.tpp




@C++ Source Code

#include "theBiasPlanet/coreUtilitiesTests/templatesTest1/ClassF.hpp"

#include <string>

namespace theBiasPlanet {
	namespace coreUtilitiesTests {
		namespace templatesTest1 {
			template <typename U> void ClassF::methodF0 (U const & a_argument0) {
				a_argument0.methodE0 <std::string> ("aaa");
			}
		}
	}
}



The ‘>’ token mentioned in the message points to the ‘>’ of ‘a_argument0.methodE0 <std::string> («aaa»);’.



In the first place, what, the hell, is «primary-expression»?



This page claims that it means a building block of more complex expressions. . . . I do not know . . .



I do not know because then, I cannot imagine any expression that is not a primary-expression. In fact, what is an expression that cannot be any building block of any more complex expression? . . . For example, an expression, ‘1 + 2’, can be a building block of ‘1 + 2 + 3’; so it should be a primary-expression, although the page does not seem to admit ‘1 + 2’ to be a primary-expression . . .



Anyway, I thank that the page explicitly states that any class name like «MyClass» and «A::B» or any «template id» like «A<int>» is a primary-expression. So, ‘std::string’ is definitely a primary-expression, is it not? . . . The some other documents I have found seem to agree that it is really a primary-expression.



Well, the thing that is before the ‘>’ in my code is . . . «std::string», an assured primary-expression. . . . Mr. compiler, a primary-expression seems to be already there . . .




2: Trying to Solve the Compile Error


Hypothesizer 7

The sloppiness of the message aside, that message was a reminiscent of my past struggle with template.



At that time, I had to put ‘typename’ in order to explicitly teach the compiler that a type name was a type name, which was for assuring that the ‘<‘-‘>’ pair was for template parameterization, not for comparing things.



Well, does the compiler require ‘typename’? How about this?




@C++ Source Code

				a_argument0.methodE0 <typename std::string> ("aaa");"



Nope.



Why? The compiler should now know that the ‘>’ is not any comparison operator, should not?




3: Solving the Compile Error, and Some Complaints


Hypothesizer 7

In fact, there seems to be a rule that any template member on any template-type dependent qualification has to be explicitly declared as a template with ‘.template’.



Well, in my case, ‘methodE0 <U>’ is a template member of ‘a_argument0’, which is a template-type dependent qualification (certainly, it is the qualification and dependent on the template type, ‘U’), so, it has to be ‘a_argument0.template methodE0 <std::string> («aaa»)’.



Hmm . . . , certainly, that has solved the problem, but is such a rule reasonable? . . . I mean, I understand that the rule exists, but I do not understand why the rule is not foolish.



You know, I am not any person that is happy just because a problem has been solved without any satisfactory explanation; I want an explanation why such a rule is necessary.



For example, this (which already exists in the above code) does not cause the error.




@C++ Source Code

			void ClassF::methodF1 (ClassE const & a_argument0) {
				a_argument0.methodE0 <std::string> ("aaa");
			}



That is because, of course, the qualification is independent of any template type, escaping the premise of the rule.



However, I do not see any reason why the flagged line is more a difficulty than the passed line is, for the compiler. . . . You know, the template itself is never compiled, but instantiations of the template are compiled, right? In fact, ‘void ClassF::methodF0 <ClassE> (ClassE const & a_argument0)’ should be no different from ‘void ClassF::methodF1 (ClassE const & a_argument0)’ except the method name.



I understand that a rule that disambiguates ‘<‘ and ‘>’ may be required, but I doubt that the present rule is wisely chosen.



If there is a reasonable necessity for the rule to exist, an understandable explanation would be nice. If the explanation is «You must just obey because I said so!», I would regard such a rule tyrannical, and foolish.

I know this is a common question but the truth is every code is different. Sometimes it’s hard to apply the concept to your code, it does not work. So please help me. What is wrong with this code? I got it from GitHub. I’m trying to compile it first before I can do a little modification, it sends temp and humidity data to ThingSpeak cloud servers.

#include <DHT.h>  // Including library for dht
#include <ESP8266WiFi.h>

String api_key = "YOUR API KEY"; // Enter your Write API key from ThingSpeak
const char *ssid = "YOUR WIFI SSID"; // replace with your wifi ssid and wpa2 key

In a legacy C++ project that is using Boost ProgramOptions. trying to compile it will yield this error message:

In file included from /usr/include/boost/lexical_cast/detail/converter_lexical.hpp:50:0,

                 from /usr/include/boost/program_options.hpp:15,

             return BOOST_ASSERT_MSG( i < N, "out of range" ), elems[i];

I didn’t find a satisfying way to fix this issue but it can be worked around fixing the issue in the source file:

First, open /usr/include/boost/array.hpp in your favourite editor as root (sudo!). I use nano.

Then, go to line 118 which reads:

return BOOST_ASSERT_MSG( i < N, "out of range" ), elems[i];

Replace that line by

BOOST_ASSERT_MSG( i < N, "out of range" );
return elems[i];

Also, 4 lines below what we just edited you’ll find another instance of

return BOOST_ASSERT_MSG( i < N, "out of range" ), elems[i];

Also replace that by

BOOST_ASSERT_MSG( i < N, "out of range" );
return elems[i];

Now. save the file and close your editor. Your code should compile now.

Why Does the Expected Primary Expression Before Occur?

The expected primary expression before error occurs when your code doesn’t follow the correct syntax. The mistakes pointed out below are the ones that often take place when you are new to programming. However, a programmer in hurry might make the same mistakes.

So, here you go:

– You Are Specifying the Data Type With Function Argument

If your function call contains the data type along with the argument, then you’ll get an error.

Here is the problematic function call:

int addFunction(int num1, int num2)
{
int sum;
sum = num1 + num2;
return sum;
}
int main()
{
int result = addFunction(int 20, int 30);
}

– The Wrong Type of Arguments

Passing the wrong types of arguments can result in the same error. You can not pass a string to a function that accepts an argument of int data type.

int main()
{
int result = addFunction(string “cat”, string “kitten”);
}

– Issue With the Curly Braces Resulting in Expected Primary Expression Before }

Missing a curly bracket or adding an extra curly bracket usually results in the mentioned error.

– The Parenthesis Following the If Statement Don’t Contain an Expression

If the parenthesis in front of the if statement doesn’t contain an expression or the result of an expression, then the code won’t run properly. Consequently, you’ll get the stated error.

How To Fix the Given Error?

You can fix the “expected primary-expression before” error by using the solutions given below:

– Remove the Data Type That Precedes the Function Argument

Remove the data type from the parenthesis while calling a function to solve the error. Here is the correct way to call a function:

int main()
{
int result = addFunction(30, 90);
}

– Pass the Arguments of the Expected Data Type

Double-check the function definition and pass the arguments of the type that matches the data type of the parameters. It will ensure that you pass the correct arguments and kick away the error.

– Ensure The Equal Number of Opening and Closing Curly Brackets

Your program must contain an equal number of opening and closing curly brackets. Begin with carefully observing your code to see where you are doing the mistake.

– Add an Expression in the If Statement Parenthesis

The data inside the parenthesis following the if statement should be either an expression or the result of an expression. Even adding either true or false will solve the issue and eliminate the error.

FAQ

You can view latest topics and suggested topics that’ll help you as a new programmer.

– What Does It Mean When the Error Says “Expected Primary Expression Before Int” in C?

The “expected primary expression before int” error means that you are trying to declare a variable of int data type in the wrong location. It mostly happens when you forget to terminate the previous statement and proceed with declaring another variable.

– What Is a Primary Expression in C Language?

A primary expression is the basic element of a complex expression. The identifiers, literals, constants, names, etc are considered primary expressions in the C programming language.

– What Are the Types of Expressions?

The different types of expressions include arithmetic, character, and logical or relational expressions. An arithmetic expression returns an arithmetic value. A character expression gives back a character value. Similarly, a logical value will be the output of a logical or relational expression.

Conclusion

The above error revolves around syntax mistakes and can be solved easily with a little code investigation. The noteworthy points depicting the solutions have been written below to help you out in removing the error:

  • Never mention the data type of parameters while calling a function
  • Ensure that you pass the correct type of arguments to the given function
  • You should not miss a curly bracket or add an extra one
  • The if statement should always be used with the expressions, expression results, true, or false

What is expected primary expression before errorThe more you learn the syntax and practice coding, the more easily you’ll be able to solve the error.

I’m trying to update latest apex on the system with Cuda9.1, pytorch 1.1.0, ubuntu16.04.
and I got the error attached at the end.

Actually, I recently got a problem that my model performance degrades significantly after I updated my docker image from cuda9.1-pytorch1.1.0-old_apex to cuda9.2-pytorch1.4.0-latest_apex.
I want to check whether the issue came from updating pytorch or updating apex.

So hopefully there is any way to install on current system (Cuda9.1, pytorch 1.1.0, ubuntu16.04.) without changing the cuda and pytorch version.
