syntax error : missing ';' before '<'

[curious2007]

in matrixsolvermechanisms.hpp I have the following:

[HTML]template <class V, class I> class LUTridiagonalSolver

{ ...

void calculateBetaGamma();

}[/HTML]
Then in matrixsolvermechanisms.cpp I have the following:

[HTML]template <class V, class I> void LUTridiagonalSolver<V,I>::calculateBetaGamma(){
...}[/HTML]


I am getting the following errors about this:

syntax error : missing ';' before '<'
'LUTridiagonalSolver' : illegal use of type 'void'
unrecognizable template declaration/definition
syntax error : '<'
'calculateBetaGamma' : is not a member of '`global namespace''

You are missing a semi-colon at the end of your class definition.

I added it and the code compiled.

It seems like this is not the problem because I have ; in the original code. So, I don't understand how it compiles as I am using Visual C++ express as well. Might it be because I have some more code in these templates than the ones I have posted or is it because the definition and the decleration of functions are in seperate files in my code?

Your compiler did not just spit out that error diagnostic text, it also gave you a
file name and a line number. In your case just before that file and line number
(probably in another .hpp or .h file) you have forgotten a trailing semi-colon.

what you say makes sense. However, I am having difficulty in identifying where that missing ";" is. The exact error message is as follows:

1>main.cpp
1>c:\users\ek\documents\visual studio 2005\projects\vec\vec\matrixsolvermechanisms.cpp(2 8) : error C2143: syntax error : missing ';' before '<'
1>c:\users\ek\documents\visual studio 2005\projects\vec\vec\matrixsolvermechanisms.cpp(2 8) : error C2182: 'LUTridiagonalSolver' : illegal use of type 'void'

1>c:\users\ek\documents\visual studio 2005\projects\vec\vec\matrixsolvermechanisms.cpp(2 8) : error C2039: 'calculateBetaGamma' : is not a member of '`global namespace''

So do you think the problem is in main.cpp or in matrixsolvermechanisms.cpp?

This error:

1>main.cpp
1>c:\users\ek\documents\visual studio 2005\projects\vec\vec\matrixsolvermechanisms.cpp(2 8) : error C2143: syntax error : missing ';' before '<'

says the compiler was compiling main.cpp and on line 28 it encountered an unexpected <. So it suggests you might are missing a ; on line 27, or 26, or 25, etc.

You have to go backwards from the < on line 28 upwards in main.cpp and into the header files you included to see where the error is. It may not be a missing semi-colon. All you know for sure is that the compiler was not expecting a < on line 28.

Fix the first error and recompile. Subsequent errors are often caused by the first error.

OK, I have found it it was before line 28 of matrixsolvermechanisms.cpp.
