RunningTask was not declared in this scope
Cloud_Strife_Han:
Hi you guys, It's the first time I used code::block to build a project. So I encounter some problems.
When I use VS2012 to build a example code[below] from msdn, it's completely successful. But it is opposite with Code::Block. I figured the problem occured when linking library or something similar, so I have to add "C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x86" to Search Directories. I alse add name of using library into Linker Settings. But I still dont work, it show some error about library! I checked file dll in my computer then it exist.
This is my code:

Any ideas for my problem?
Thank for reading! Sorry for my bad english.
BlueHazzard:
Hi,
first of all codeblocks is not a compiler. So technically you do not compile with codeblocks but with gcc. So you use a new compiler to compile your code. If you have any problems and you search the web you should not search for "help compiler error codeblocks" but "help compiler error gcc"
Second. Thank you for providing source and some build messages. But we need other information:

this are not linker but compiler errors, so you are missing a header here.
BTW. you can use codeblocks also with the msvc compiler so it should compile straight the way...
Cloud_Strife_Han:
Thank for your reply.
I am sure I have linked the header into code::block (Build Option -> Linker Setting -> Add and type the header name) it still doesnt work!
I'm using code::block version 17.04 on windows 7 with TDM-GCC MinGW Compiler (ver 5.1.0). This occur happens immedialy when I build project.
I attempted to:
1. Linking the header
2. Add Search Directories
3. Copy header files into project then add as #include "header" then I see no error about library, just has last one error ||error: ld returned 1 exit status|!

and to help you we need the full rebuild log as is described in the FAQs and not the build messages
