I have a class with the following -
boost::condition_varaible cond_;
When I try and compile -
[rmitra#butterfly boost]$ make EXE=thread_safe_stack
g++ -L /usr/local/lib -lboost_thread -o thread_safe_stack thread_safe_stack.cpp
I get the following error -
thread_safe_stack.cpp:25: error: ‘condition_varaible’ in namespace ‘boost’ does not name a type
thread_safe_stack.cpp: In member function ‘void thread_safe_stack::push(const T&)’:
thread_safe_stack.cpp:34: error: ‘cond_’ was not declared in this scope
thread_safe_stack.cpp: In member function ‘void thread_safe_stack::pop(T&)’:
thread_safe_stack.cpp:42: error: ‘cond_’ was not declared in this scope
make: * [exe] Error 1
Please explain what the problem is.. I am using boost 1.54
I have the following headers included in my source file -
#include <boost/thread.hpp>
#include <boost/thread/thread.hpp>
#include <boost/thread/exceptions.hpp>
#include <boost/thread/mutex.hpp>
#include <boost/thread/pthread/condition_variable_fwd.hpp>
#include <iostream>
#include <stack>
#include <iterator>
#include <algorithm>
You're spelling condition_variable wrong:
boost::condition_varaible cond_;

I want to compile a simple test project for a library that makes use of a ftd2xx driver. I already compiled it successfully on linux and I'm trying to do the same on Windows. The main difference are some minor modification to the library.
The test file I want to compile is this:
//#include "HPX-linux.h"
#include "HPX-Windows.h"
#include <stdlib.h>
#include <stdio.h>
int main(){
int devs;
getSerialNum(&devs);
printf("%d\n\n", devs);
simpleTest("./myTest/");
return 0;
}
And the preprocessing directives of HPX-Windows.h are as follows:
#ifndef HPXLINUX_H
#define HPXLINUX_H
#include <math.h>
#include <stdint.h>
#include <time.h>
#include <stdio.h>
#include <unistd.h>
#include <sys/types.h>
#include <sys/time.h>
#include "ftd2xx.h"
#include <pthread.h>
// typedefs
//typedef uint16_t DWORD;
#ifndef __cplusplus
typedef uint8_t bool;
#endif
// static const defines
#ifndef __cplusplus
#define TRUE 1
#define FALSE 0
#endif
#define SUCCESS 0
#define FAILURE -1
#define RETRIEDTOOMANY -10
#define LOSTHEADFRAME -11
#define GOTAV 2
#ifdef __unix__
#define PRELIB extern
#elif _WIN32
#ifdef ADD_EXPORTS
#define PRELIB __declspec(dllexport)
#else
#define PRELIB __declspec(dllimport)
#endif
#endif
#ifdef __unix__
#define CALL
#elif _WIN32
#define CALL __cdecl
#endif
About ftd2xx, I have 2 .h headers, a .lib and a .dll.
With the driver properly installed, I could compile the library on linux with:
gcc -o test test.c -Wall -Wextra -lHPX-linux -lftd2xx -lm
I'm using MinGW on Windows. The command I'm using is:
gcc test.c HPX-Windows.c -L -lftd2xx -g
And then I get a list of errors type "undefined reference to _imp__*", being * a function. I expected them to be the functions of ftd2xx.h, but it also happens to function declared in HPX-Windows.h, including getSerialNum and simpleTest. Why does it happen when I'm using a .c source file instead of a library?
The error is caused by symbols exported with __declspec(dllimport) in header files that can't be imported from a shared library (.DLL).
I would recommend creating a libftd2xx.dll.a file from the ftd2xx.dll file and linking with that (e.g. if the files are in the current directory using -L. -lftd2xx.dll).
Or you could probably just link with the .dll file by specifying it in the gcc command, something like this: gcc -o test.exe test.c HPX-Windows.c ftd2xx.dll -g).
If that doesn't work check ftd2xx.h to see where __declspec(dllimport) is imported and see if you can set a define that causes the header to not use __declspec(dllexport)/__declspec(dllimport) and link with your lib file in case it's a static library (something like: gcc --static -o test.exe test.c HPX-Windows.c -L. -lftd2xx -g).
I am trying to run the make file of some application. The source code is
INCL= -I/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/GLUT.framework/Versions/A/Headers
LIBD= -L/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries
evmovie: evmovie.c
cc evmovie.c -o evmovie $(INCL) $(LIBD) -framework GLUT -lGL -lGLU
When I run it in the terminal, it gives me a lot of warnings. The majority of them are saying a lot of glut function is deprecated since Mac OS 10.9. I just ignore them. However, one of the crucial errors is the following.
directory not found for option '-L/Developer/SDKs/MacOSX10.15.sdk/System/Library/Frameworks/OpenGL.framework/Versions/A/Libraries'
ld: library not found for -lGL
I do not not know how to fix this. Can anyone help me?
By the way, the source code of evmovie.c is
#define _CRT_SECURE_NO_WARNINGS
#include <stdio.h>
#include <stdlib.h>
#if defined(WIN32) || defined(_WIN32)
#include <GLUT/glut.h>
#include <windows.h>
#include <io.h>
#else
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
#define __cdecl
#define _fileno fileno
int _filelength(int fd)
{ struct stat statbuf;
fstat(fd,&statbuf);
return statbuf.st_size;
}
#if defined(__APPLE__)
#include <GLUT/glut.h>
#else
// unix, linux
#include <GL/glut.h>
#endif

I want to get information about the "c:\", but when I use GetVolumeInformationA() function it say undefined identifier GetVolumeInformationA..
I have already include this header:
#include <FileAPI.h >
#include <WinBase.h>
#include <windows.h>
and I did see there exist a declaration in FileAPI.h, what should I do to use GetVolumeInformationA?
I am compiling following simple code in ffmpeg.
#include "stdafx.h"
#include <libavcodec/avcodec.h>
#include <libavformat/avformat.h>
void main()
{
av_register_all();
}
all the ffmpeg headers i have included in project properties.
but i am getting the following error on compiling.
Error 1 error C1004: unexpected end-of-file found dev\include\libavutil\common.h 87 1

Try define __STDC_CONSTANT_MACROS before including those headers to see if problem can be solved.
#include "stdafx.h"
extern "C" {
#define __STDC_CONSTANT_MACROS
#include "libavcodec/avcodec.h"
#include "libavformat/avformat.h"
};
See http://bigbang.waterlin.org/bang/using-ffmpeg-under-windows-visual-cpp-environment/

I want to have a .cuh file where I can declare kernel functions and host functions as well. The implementation of these functions will be made inside the .cu file. The implementation will include the use of the Thrust library.
In the main.cpp file I would like to use the implementation that is inside the .cu file. So let's say we have something like this:
myFunctions.cuh
#include <thrust/sort.h>
#include <thrust/device_vector.h>
#include <thrust/remove.h>
#include <thrust/host_vector.h>
#include <iostream>
__host__ void show();
myFunctions.cu
#include "myFunctions.cuh"
__host__ void show(){
std::cout<<"test"<<std::endl;
}
main.cpp
#include "myFunctions.cuh"
int main(void){
show();
return 0;
}
If I compile by doing this:
nvcc myFunctions.cu main.cpp -O3
And then run the executable by typing ./a.out
The test text will be printed.
However, if I decide to include -std=c++0x by using the following command:
nvcc myFunctions.cu main.cpp -O3 --compiler-options "-std=c++0x"
I get a lot of errors, some of which are the following:
/usr/include/c++/4.6/x86_64-linux-gnu/./bits/c++config.h(159): error: identifier "nullptr" is undefined
/usr/include/c++/4.6/x86_64-linux-gnu/./bits/c++config.h(159): error: expected a ";"
/usr/include/c++/4.6/bits/exception_ptr.h(93): error: incomplete type is not allowed
/usr/include/c++/4.6/bits/exception_ptr.h(93): error: expected a ";"
/usr/include/c++/4.6/bits/exception_ptr.h(112): error: expected a ")"
/usr/include/c++/4.6/bits/exception_ptr.h(114): error: expected a ">"
/usr/include/c++/4.6/bits/exception_ptr.h(114): error: identifier "__o" is undefined
What do these errors mean and how can I avoid them?
Thank you in advance
If you look at this specific answer, you'll see the user is compiling an empty dummy app with the same switch you are using and getting some of the exact same errors. If you restrict the usage of that switch to compiling .cpp files, you'll probably have better results:
myFunctions.h:
void show();
myFunctions.cu:
#include <thrust/sort.h>
#include <thrust/device_vector.h>
#include <thrust/remove.h>
#include <thrust/host_vector.h>
#include <thrust/sequence.h>
#include <iostream>
#include "myFunctions.h"
void show(){
thrust::device_vector<int> my_ints(10);
thrust::sequence(my_ints.begin(), my_ints.end());
std::cout<<"my_ints[9] = "<< my_ints[9] << std::endl;
}
main.cpp:
#include "myFunctions.h"
int main(void){
show();
return 0;
}
build:
g++ -c -std=c++0x main.cpp
nvcc -arch=sm_20 -c myFunctions.cu
g++ -L/usr/local/cuda/lib64 -lcudart -o test main.o myFunctions.o
