unable to compile cuda code, compiling error - cuda

I'm getting an error when i try to compile and build cuda code
error C2065: 'threadIdx' : undeclared identifier
error C2228: left of '.x' must have class/struct/union

simply try changing the extension of your main *.cpp file to *.cu (other than the kernel file which must be *.cu)

Fatal error: Class 'Hash' not found, CakePhp-2

I am trying to run a CakePhp-2 project but it shows the error:

Make sure you have the folder seeing and the lib folder with the items you really need

Cannot compile Cuda 7.0 sample

I installed CUDA 7.0 as described here on Ubuntu 14.04. I look at matrix mul example, if I start executable file matrixMul that runs, but if I try to compile it gives me error on libraries.
i.e
user#Mars:~/Documenti/Bello/NVIDIA_CUDA-7.0_Samples/0_Simple/matrixMul$ nvcc matrixMul.cu
matrixMul.cu:36:30: fatal error: helper_functions.h: File o directory non esistente
#include <helper_functions.h>
^
compilation terminated.
The problem was caused by trying to compile the sample using nvcc without the correct compiler options, rather than with the supplied makefile. Using the makefile allowed the compilation to work successfully.

'ED_UNASSIGNED' undeclared during mysql installation from sources

I'm getting an error during mysq installation from sources

How to solve this error?
I checked mysql sources and indeed there is no ED_UNASSIGNED variable.
I had similar error.
I was using different folder for throwing CMAKE build files. From where I used to run "make".
"mysql-5.6.15" source folder
"MySQL Build" folder where I did throw make files and intended to build binaries.
I had a space in that folder name. Removing the space did the trick.
Though I see there is no spaces in your path but still make sure you are using no folder with "space". Having space in build folder also gives errors when your try to build MySQL from source on Windows.

vc++ - I want to compile a program which uses mysql, please direct me

Hai,
I done a server program in vc++(using visualstudio 2008). At that time it worked perfectly. But after that I uninstalled the visualstudio 2010. Now I can't open that pro file using vs2008(it is saying that it can't open the file). So I copied the header,cpp files and tried to compile , but it's not compiling. I added the libmysql.lib in properties->dependencies. And added the include path also. But still I am getting the following errors.
So he I am producing a stub.
#include <winsock.h>
#include <mysql.h>
int main()
{
MySql a;
return 0;
}
the errors I am getting are
error C2065: 'MySql' : undeclared identifier
error C2146: syntax error : missing ';' before identifier 'a'
error C2065: 'a' : undeclared identifier
I don't know what I am doing wrong. Somebody please help me.
You have the case wrong for the declaration:
MySql a;
should be
MYSQL a;
