Visual C++ Express 2008 (free version) I get the following unexpected end of file message when entering code straight from the book "Exploring C++ / Ray Lischner" (email the author claims is his in the book doesn't exist, and there is no book web forum): ------ Build started: Project: ch39_1, Configuration: Debug Win32 ------ Compiling... generate_id.cpp c:\documents and settings\ralf becker.ralf_work\my documents\visual studio 2008\projects\c++\ch36_42\ch39_1\ch39_1\generate_id.hpp(14) : fatal error C1004: unexpected end-of-file found main.cpp c:\documents and settings\ralf becker.ralf_work\my documents\visual studio 2008\projects\c++\ch36_42\ch39_1\ch39_1\generate_id.hpp(14) : fatal error C1004: unexpected end-of-file found Generating Code... Build log was saved at "file://c:\Documents and Settings\Ralf Becker.RALF_WORK\My Documents\Visual Studio 2008\Projects\c++\ch36_42\ch39_1\ch39_1\Debug\BuildLog.htm" ch39_1 - 2 error(s), 0 warning(s) ========== Build: 0 succeeded, 1 failed, 0 up-to-date, 0 skipped ========== The code is as follows - a header file for a class; a .cpp file for the related member functions; and a main.cpp file (very short as just learning about concepts): generate_id.hpp #ifndef GENERATE_ID_HPP_ #define GENERATE_ID_HPP_ class generate_id { public: generate_id() : counter_(0) {} long next(); private: short counter_; static short prefix_; static long int const max_counter_ = 32767; }; #endif generate_id.cpp #include "generate_id.hpp" short generate_id::prefix_(1); long const generate_id::max_counter_; long generate_id::next() { if (counter_ == max_counter_) counter_ = 0; else ++counter_; return prefix_ * (max_counter_ + 1) + counter_; } main.cpp #include <iostream> #include <ostream> #include "generate_id.hpp" int main() { generate_id gen; for (int i = 0; i!= 10; ++i) std::cout << gen.next() << '\n'; } I realize that typical solutions to this problem include: (a) Check all braces etc. close properly, and (\b) check if any precompiled headers are used (they are not - option is disabled). I am obviously learning C++, so maybe this is just trival for you guys. What throws me off is that the program compiles and runs 100% fine if the pre-compiler commands #ifndef/#define/#endif are removed; output produced then is as expected: 32769 . . . 32778 So the error only starts when adding the precompiler #conditionals. However, the IDE recognizes the conditional proper, as witnessed by... - producing a 'missing #endif' error if i remove #endif (just to check it), and - by indicating that #endif corresponds to #ifndef in the usual IDE way (brief blinking of #ifndef after entering #endif) Sorry for being verbose but meant to provide info as precisely as I could. Any help would be greatly appreciated. Throws me off quite a bit if i got trouble using such precompiler commands. Best, OGtR. |

Issue resolved:
There needs to be a cr or similar after the #endif command. Once that is added, the program compiles fine. My apologies - might seem as if i didn't think about this before posting, which isn't true at all. Was stuck for hours but right after posting noticed. Best, O. |

Hello
 Assuming from the error code you're using a Microsoft compiler, see the following: http://msdn.microsoft.com/en-us/library/4e...28VS.71%29.aspx Is there a newline after the #endif in generate_id.hpp? Some compilers will choke if there's not one there.

In the event I fail to reply within twenty-four hours, feel free to send me a PM.
And that means I solve problems. Not problems like "What is beauty?" .. 'cause that would fall under the purview of your conundrums of philosophy....  |
