c++ - Debugging a DLL that uses __stdcall and pragma linker -


i want debug dll. dll exports functions , voids:

this header:

#ifdef codec_exports #define codec_api __declspec(dllexport) #else #define codec_api __declspec(dllimport) #endif  extern "c" codec_api int __stdcall spxinit(void); extern "c" codec_api int __stdcall spxencode(unsigned char* inbuf, unsigned char* outbuf, unsigned int inlen); extern "c" codec_api int __stdcall spxencodenormal(void); extern "c" codec_api int __stdcall spxdecode(unsigned char* dinbuf, float* doutbuf,     unsigned int dinlen); extern "c" codec_api int __stdcall spxfree(void);  #pragma comment(linker, "/export:spxencode=_spxencode@12") #pragma comment(linker, "/export:spxencodenormal=_spxencodenormal@0") #pragma comment(linker, "/export:spxdecode=_spxdecode@12") #pragma comment(linker, "/export:spxinit=_spxinit@0") #pragma comment(linker, "/export:spxfree=_spxfree@0")

i added new project solution , added following cpp file:

#include "stdafx.h" #include "codec.h"  int _tmain(int argc, _tchar* argv[]) {     return 0; }

now before trying else, wanted compile new project, vc2010 telling me 

"error lnk2001" unresolved external symbol "_spxdecode@12" "error lnk2001" unresolved external symbol "_spxencode@12"

etc...

so guess missed something, don't see what.

you need add reference dll project
project properties->common properties->references

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
