I am using Open GL ES 3.1 in Android app with native C++ code. So I need to run a C++ lib with Android support.
I have used some Open GL ES functions and they worked well. But when I tried to use glDispatchCompute, a linker gave a following error: undefined reference to 'glDispatchCompute'.
Here is the call:
glDispatchCompute(10, 1, 1);
Here are my includes:
#include <string>
#include <jni.h>
#include <GLES3/gl31.h>
#include <GLES/egl.h>
#include <GLES/gl.h>
#include <GLES3/gl3ext.h>
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
Here are my options for clang:
-lGLESv3 -lGLESv2 -lGLESv1_CM -lEGL
Also I tried -lGLESv3 -lEGL with the same effect.
The problem was in not using proper java libraries and activities. In sample app there are 3 activities in Java. After adding them everything worked well.

I'm trying to compile the c code generated by Embeddinator-4000 but Xcode can't find the specified path to Mono.
These are the headers that are currently giving me problems:
#include <mono/jit/jit.h>
#include <mono/metadata/mono-config.h>
#include <mono/metadata/assembly.h>
#include <mono/metadata/debug-helpers.h>
#include <mono/metadata/object.h>
However these paths work:
#include <Mono/mono-2.0/mono/jit/jit.h>
#include <Mono/mono-2.0/mono/metadata/mono-config.h>
#include <Mono/mono-2.0/mono/metadata/assembly.h>
#include <Mono/mono-2.0/mono/metadata/debug-helpers.h>
#include <Mono/mono-2.0/mono/metadata/object.h>
The problem is that jit.h includes <mono/metadata/appdomain.h> and Xcode can't find it.
Is there a way to alias the framework so I don't have to modify my current install of Mono?
Thanks!
I'm trying to run a Visual Studio cpp project created by a friend of mine. I'm trying to run the file without VS. But I'm getting a list of errors, all in the same format:
inlining failed in call to always_inline '__m256d _mm256_broadcast_sd(const double*)': target specific option mismatch|
It runs correctly in VS with release mode and breaks when run in debug mode.
The includes are as follows:
#include "stdafx.h"
#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include <time.h>
#include <vector>
# include <omp.h>
#include <chrono>
#include <fstream>
#include <algorithm>
#include <immintrin.h>
using namespace std::chrono;
using namespace std;
and the error is called from here:
double zero = 0;
__m256d acc = _mm256_broadcast_sd(&zero);
Update:
I'm using the this command to run it: g++ -std=c++0x multip.cpp -o multip, is there an additional parameter to add -mavx to the compiler invocation?
"Target specific option mismatch" means that you're missing a feature flag from your GCC invocation. You probably need to add -mavx to your compiler invocation.
If you're intending to run this on your computer only, -march=native will turn on all the feature flags that your own machine supports.
So far I was able to install CUDA and it works fine.
However, I have no idea how to set up XCode for CUDA. And the posts out there seem to be really outdated and full of missing links and files. Also XCode seem to have changed a lot since 2009.
To begin, If I create a new project should I choose "Empty" or "External Build System" or something else?
I suggest using CMake:
1) Install latest CMake from http://www.cmake.org/download/
2) Create CMakeLists.txt and main.cu:
CMakeLists.txt
cmake_minimum_required(VERSION 3.3)
project(cuda_test)
find_package(CUDA REQUIRED)
cuda_add_executable(cuda_test main.cu)
main.cu (taken from http://thrust.github.io/)
#include <thrust/host_vector.h>
#include <thrust/device_vector.h>
#include <thrust/generate.h>
#include <thrust/sort.h>
#include <thrust/copy.h>
#include <algorithm>
#include <cstdlib>
int main()
{
thrust::host_vector<int> h_vec(32 << 20);
std::generate(h_vec.begin(), h_vec.end(), rand);
thrust::device_vector<int> d_vec = h_vec;
thrust::sort(d_vec.begin(), d_vec.end());
thrust::copy(d_vec.begin(), d_vec.end(), h_vec.begin());
return 0;
}
3) Use CMake GUI or command line to create a Xcode project out of the above (the following uses the cmake command line)
cmake -G Xcode
Hey so i am trying to use fmod as i have to take the modulus of two doubles. My make file does the following.
gcc -static -lm vm_main.c vm_options.c vm_menu.c vm_utility.c -o main
so the -lm tag should include the math header right?
i have included math.h in my files.
#include "vm_menu.h"
#include "vm_type.h"
#include <math.h>
#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <malloc.h>
im a little confused as to why this is occurring... :/
so the -lm tag should include the math header right?
No, it tells the linker to link to libm, the math library. That's a library, not a header. But the order of linker options is important so it needs to come after the files that use it.
I don't know where is the function savePolygonFileSTL in pcl 1.6. Which file do I have to include?
Here it says that it is part of
#include <pcl/pcl_config.h>
#include <boost/cstdint.hpp>
#include <cstdlib>
#include <iostream>
#include <stdarg.h>
#include <stdio.h>
#include <math.h>
Anyway VS2010 doesn't find it, and also with manually search I didn't find the definition of that function in all pcl 1.6 folders. Neither savePolygonFile exists or similar.
How is it possible? There is something that I don't know? Please help me.
Thanks a lot
As mentioned in this tutorial, you could try to include the following include at the top of your code:
#include <pcl/io/pcd_io.h>
Update: by looking at the PCL 1.6 source code here, it looks like the savePolygonFileSTL function is defined in the vtk_lib_io.h header. Try to include it adding this line to your code:
#include <pcl/io/vtk_lib_io.h>
Please be sure to have a VTK enabled PCL build.
