i m getting error

error: expected ‘;’ before ‘(’ token
on line 121 of this code

u_int32_t* decode(string[8]=NULL, string[2]=NULL);
the code is part of this header library
http://pastebin.com/NS8V0ByK
and the function definition is in this code at line 217
http://pastebin.com/M9fuppa1

it is kind of urgent so kindly any of you can help i will be thankful.
i am compiling on Ubuntu 12.04 32bit with gcc (Ubuntu/Linaro 4.5.3-9ubuntu1) 4.5.4

Post the whole code maybe? I fail to see the error.

[hasanalikhattak]

i have posted the whole code of the header on the paste bin
http://pastebin.com/NS8V0ByK
and also the code for the function definition is in this code at line 217 http://pastebin.com/M9fuppa1
you can also see the whole project over project site for Google Code (http://code.google.com/p/ns2-neoclassic/source/detail?r=4)

According to the compilers (clang++ and g++) that is a valid function definition. I'm assuming string is a std::string.

You're probably missing a semicolon on the line before that one.

That said, when you have errors, do post a compilable example and not just a line or two. Compilers can usually only guess at where you made a mistake, and they're often wrong (because they can only look at what you wrote and not what you meant).

Edit: that seems not to be your problem after all, at least if the code you pasted is actually the code you compiled. Sorry.

[hasanalikhattak]

the whole code is a huge project and very lengthy code. that is why i have posted on pastebin and also shared the project on google code.

i am not very regular on forums so i don't know the requirements and such things. i hope you guys can be tolerable on that aspect :)

If I saw that error on that line of code, the first thing I would do would be to check that the definition of "u_int32_t" is visible to the compiler at that point. It looks to me as if the compiler is trying to interpret it as a variable or function name and getting confused.

Your header file is missing an include statement for the <string> header file. In addition, the function prototype you have above fails to note that string is declared within the std namespace.

Change your prototype to be:


#include <string>
...
u_int32_t* decode(std::string[8]=NULL, std::string[2]=NULL);

Make a similar adjustment in the cpp source file.

P.S. I agree with Jim_24601; it would also appear that you are missing a typedef for u_int32_t.
