[solved]codeblocks doesn't build my application and give's this error

[amir ramezani]

hi all, I want to build my app and got this error:

Code: [Select]

<command-line>:0:9: error: expected unqualified-id before numeric constant
I'm using Code::Blocks and GCC 4.8.2 (MinGW) this is the command to build my source file:

Code: [Select]

g++.exe -std=c++11 -Wall -DHAVE_W32API_H -D__WXMSW__ -DwxUSE_UNICODE -DwxUSE_UNICODE_MSLU -DCRYPTOPP_ENABLE_NAMESPACE_WEAK -DBOOST_THREAD_USE_LIB -Dunicode
-DSFML_STATIC -g -IC:\Dev-Cpp\include -c F:\projects\cpp\AGK\AGK.cpp -o obj\Debug\AGK.o
I haven't got this error in all of my projects such as my Operating system and everything that I'm writing   
that is code to build a debug version
I don't know what is that problem

Quickly  typing the error in Google, reveals that it's most likely just a simple syntax error.

Can you post the code where of where the compile complains?

[amir ramezani]

that isn't a syntax error, it is a command-line error
this is the build log:

the other errors are for wxWidgets, and after I write my implementation, they'll be fixed
but the first one is for command-line and I don't know how to fix it
when I select the error from the list, nothing happen's and CB doesn't go there for fixing the problem
now, what can I do?
I've search it in google, but I don't found anything

[eXpl0it3r]

Ah since you cut them apart it wasn't obvious.

Well the numbers ":0:9:" indicate that the error is on line 0 character 9, which seems to be the "11" of "-std=c++11", but I've no idea why it would error out at that point...
Since you're using 4.8.x you don't need to specify -std=c++11 (iirc).

Is there a reason you use the testing 4.8.2 branch of MinGW instead of the stable 4.8.1?

[amir ramezani]

I'm using the updated compiler of MinGW.org, not TDM
if I don't write -std=gnu++11, it doesn't support C++11
I've tried it in some of my projects
I've tried to remove -Wall, but that error occur's

Amir, I'm using MinGW "distro" from http://nuwen.net/mingw.html for my software dev on windows systems. You should give it a try.
You will need to change GCC compiler executable names in codeblocks compiler settings to make it work.
Nuwen distro GCC is in c++11 mode by default.

[eXpl0it3r]

Well my bad, I thought GCC had changed their defaults, but apparently only a few builders did so (i.e. nuwen), thus you'll have to keep specifying -std=c++11...

If you use a simple application and try to compile it with -std=c++11 does it fail as well?

[amir ramezani]

I can compile all of my other projects and I don't get that error
but, this give's that error
I've wrote a makefile and wrote the command that codeblocks use's it to build my application, and the same error
I don't think the problem is in my code
