problem compiling Convolution.cpp #55

Open GoogleCodeExporter opened 8 years ago

GoogleCodeExporter commented 8 years ago 
I am using AMD APP SKD v2.6 on Ubuntu 10.04 on 32bit Intel CPU, with 
compiler gcc version 4.4.5.

After generating the Makefile and running make, the code for Convolution.cpp 
stops compiling with the following error:

[ 30%] Building CXX object

Error 2
make: *** [all] Error 2

It seems that the compiler does not find the functions exit and alloca because 
the corresponding C headers are not included. If I add the line

#include<cstdlib>

the program compiles, but on running it exits with the error:

ERROR: reading Convolution.cl (-1)

Any help would be appreciated.

The problem is that I was using Ubuntu 10.04 and the supported versions are 
11.xx

The file is simply missing from the build directory

The kernel file Convolution.cl is read at run time of the executable 
OpenCLConvolutionChap3, so must be present in the same folder as that 
executable. In the HelloWorld example of Chapter 2, the HelloWorld.cl file is 
read into a string at compile time of the HelloWorld executable, so this was 
not an issue there.

Having a separate build tree for these examples isn't necessary, since these 
examples can be built simply in the src tree itself. For example in the 
src/Chapter_3/OpenCLConvolution folder (on a Mac) by 

$ c++ -o OpenCLConvolutionChap3 -framework openCL Convolution.cpp

and then running the example with

$ ./OpenCLConvolutionChap3

gives the proper output.
