I'm using GMP and getting an illegal instruction that I have found to be caused by mpf_set_d. I'm programming in Netbeans with cygwin in c++.
Thanks in advance!
Edit:
I have a folder containing the following files:
.dep.inc, cyggcc_s-seh-1.dll, cyggmp-10.dll, cyggmpxx-4.dll, cygstdc++-6.dll, cygwin1.dll, my executable, gmp.h, gmpxx.h, libgmp.a, libgmp.la, libgmp.lai, libgmp.lai, libgmp.libcmd, libgmpxx.a, libgmpxx.la, libgmpxx.lai, main.cpp, main.o, main.o.d, Makefile, text file needed for program and folders needed for program.
I have tried many things, one of which was to add an executable to this folder that ran the following code:
#include <cstdlib>
#include <iostream>
#include <stdio.h>
#include "gmpxx.h"
#include <stdarg.h>
#include <string>
using namespace std;
int main()
{
mpf_t a;
mpf_init(a);
mpf_set_d(a,3.1415926535);
cout << "works" << endl;
}
Running this on my own computer with GMP installed gives me 'works' after which it closes, on another computer that does not have GMP installed it throws an error and closes. The error is an exception: status_illegal_instruction.
I can't give you my code but I can post snippets. Please tell me if more information is necessary!
Thanks again.
Edit 2:
The same counts for mpf_set_str as well as the c++ wrapper.

I am working on a C++ project using CodeBlocks on Windows but then decided to switch to NetBeans IDE 8.2.
Within my project, I am calling another executable file with some passed parameters (I run the other .exe with suitable parameters then I take the output of it to use in my main project), and it used to work on CodeBlocks but not on NetBeans.
The code is the following:
#include <iostream>
#include <fstream>
#include <stdlib.h>
#include <cstdlib>
#include <string.h>
#include <sstream>
#include <vector>
#include <stdio.h>
#include <stdlib.h>
#include <windows.h>
#include "My_Constants.h"
#include "Data.h"
#include "Parameters.h"
#include "Pattern.h"
#include "Squish.h"
#include "Deserializer.h"
#include "Automatic_Run.h"
using namespace std;
int main()
{
Parameters parameters;
parameters.mode = SQUISH;
Automatic_Run runner;
string inputname;
//--------------------------------User Input-------------------------------------
cout << "enter input file name \n";
getline(cin, inputname);
parameters.inputFileName.assign(inputname);
cout<<"=============================================================================\n";
//--------------------------------Running SQUISH/first call--------------------------
cout<<"Running SQUISH - first call\n";
char command[1000]="";
string passedParameters = " -i "+parameters.inputFileName +" -f "+ "t";
strcat(command,"C:\\Users\\Administrator\\Documents\\CodeBlocksProjects\\TestSQUISH\\bin\\Debug\\TestSQUISH.exe ");
strcat(command,passedParameters.c_str());
int result = system(command);
// the rest of the code(not relevant to the problem)
return 0;
}
On CodeBlocks, it used to work perfectly and give me the output as a file in the path of my main project (the one I am calling TestSQUISH from). However, now on NetBeans, I am getting the following error:
sh: C:UsersAdministratorDocumentsCodeBlocksProjectsTestSQUISHbinDebugTestSQUISH.exe: command not found
I checked the terminal of NetBeans to get an idea of what is happening (assuming it might be related) and I noticed that I have to change the path first, then run the executable using:
./ TestSQUISH.exe (+parameters)
However, that also didn't work for my project.
Can anyone please suggest a solution or tell me how I can make NetBeans run the command on a Windows terminal as CodeBlocks used to do?
Go to the project settings and set the project path for execution to be the folder where the other application is.
OR
Set the system path to include that folder.
Thanks to the comment of #Yksisarvinen, I was able to solve the problem.
Noticing that NetBeans uses the shell and not the Windows-style commands and after using the NetBeans own terminal to really get a clear idea of how it translates paths, I was able to run the code successfully using the following:
char command[1000]="";
string passedParameters = " -i "+parameters.inputFileName +" -f "+ "t";
strcat(command, "/cygdrive/c/Users/Administrator/Documents/CodeBlocksProjects/TestSQUISH/bin/Debug/TestSQUISH.exe ");
strcat(command,passedParameters.c_str());
int result = system(command);
Netbeans terminal adds cygdrive to the beginning of the path, and uses c instead of C:.
And in case the executable is in the same directory as your own project then this would be enough:
char command[1000]="";
string passedParameters = " -i "+parameters.inputFileName +" -f "+ "t";
strcat(command ,"./TestSQUISH.exe ");
strcat(command,passedParameters.c_str());
int result = system(command);
I'm creating windows console app that has many pages (split in files). I'm facing a problem when executing the program and Visual Studio throws 'startpage' identifier not found error (startpage is the function and the file name is startpage.h)
I've tried using:
external int startpage(); and
int startpage();.
I've tried changing only the function name too (so the file and function don't use the same name).
I have no idea why this is happening. Other files with different functions are working. The file "startpage.h" uses two functions defined in other files, and those are not throwing any errors.
#include "include/startpage.h"
#include <iostream>
#include <conio.h>
#include "include/concol.h"
#include "pch.h"
#include <iostream>
using namespace std;
int main()
{
startpage();
}
```
Here is the error:
Error code: C3861: 'startpage' identifier not found
Move #include "pch.h" to the top. The compiler ignores everything above the inclusion of precompiled header. – Igor Tandetnik
This worked!
Thank you so much guys!
When I try to build test sources I get an error like after this.
stl_tree.h:542:14: error: ‘__node’ does not name a type
::new(__node) _Rb_tree_node<_Val>;
Executor's content.
#include <CppUTest/TestHarness.h>
#include <CppUTest/CommandLineTestRunner.h>
#include <CppUTest/UtestMacros.h>
#include <CppUTestExt/MockSupport.h>
int main(int argc, char** argv) {
MemoryLeakWarningPlugin::turnOffNewDeleteOverloads();
return CommandLineTestRunner::RunAllTests(argc, argv);
}
My test' s source code starts with below includes.
#include <CppUTest/TestHarness.h>
#include <CppUTest/CommandLineTestRunner.h>
#include <CppUTest/UtestMacros.h>
#include <CppUTestExt/MockSupport.h>
#include <iostream>
#include "common/data_util_astro_cfg.h"
TEST_GROUP(ASTRO_UTIL_TEST) {
void setup() { }
void teardown() { }
};
And the "common/data_util_astro_cfg.h" file has following includes.
#include "../data/data_type_file.h"
#include <json/json.h>
static AstroConfigs toAstroConfigs(std::string content)
My problem is I get compilation error with these includes, when I remove line json.h include everything is fine I can get binary output.
I think the problem is about new operator' s conflict. The solution is offered by Cpputest side and it is located on http://cpputest.github.io/manual.html#memory_leak_detection. But it isn't clear somehow. :(
The question has been already defined on Compilation error after including <map>. It is so similar to mine but the problem has solved with creating new project. In that case I have no option for that. I'm using Yocto project and the project has created with auto generation tools as well.
Can you help me on this? (Thank you for your time.)
Unfortunately, I solved the problem after a while. It seems something wrong with CPPUTest. At the top of the test file, I have several includes. Some of them belong to CPPUTest library, some of them are mine. My includes are following CPPUTest that's why I’m getting an error. If I changed their places, it would be working correctly. It seems meaningless, but it is the correct solution. ”PROBLEM SHOULD BE RESOLVED WITH DEFINE CPPUTEST LIBRARIES AT THE BOTTOM OF YOUR INCLUDE LIST.”
Netbeans fails compilation on:
#include <string>
Output says:
main.c:10:18: fatal error: string: No such file or directory
#include <string>
The previous two declarations are included fine:
#include <stdio.h>
#include <stdlib.h>
I have removed all the code afterwards to make sure.
I am using cygwin_64 and it installed as per Netbeans c++ installation manual and shows versions in CLI
I am new to C++ and I know there have been similar questions, but the answers didn't help me.
Just try to create new project and follow these steps:
Click File->Create project.
Choose C/C++, then C/C++ application, click Next.
Enter project name and in the right choose C++ in combobox. Or C++11.
I made a copy of a makefile that worked for program A for a new program called program B. To keep things simple program B has all of the same include directives as program A. The only changes made to the new makefile are the obvious changes to the list of object files and the name of the created executable. I can also be sure that the compilation error is not caused by anything in main() or any of the functions of program B. Yet somehow I have an error when I use the make command that goes:
/usr/local/triclops/lib/libtriclops.a(triclops.o): In function `triclopsGetDynamicLibPath':
triclops.cpp:(.text+0x198): undefined reference to `dladdr'
In my makeflie I have the following relevant lines:
CPPFLAGS+=-I/usr/local/triclops/include
LDLIBS+=-L/usr/local/triclops/lib
LDLIBS+=-lpgrlibdcstereo -ltriclops -lpnmutils
I appreciate you help, so thanks in advance. I do not know a lot about makeflies, so I am just trying to reuse the code effectively.
EDIT
Both program A and program B have the same include directives
#include "stereoCamera.h"
#include "Aria.h"
#include <iostream>
#include <cstdio>
#include <cv.h>
#include <highgui.h>
#include <cmath>
#include <vector>
#include <opencv2/highgui/highgui.hpp>
Program B can be thought of essentially as this plus an empty int main(){ return0;} while program A does contain much code and has been working for quite some time now.
You could try linking against libdl with -ldl added to your second LDLIBS+= line. You may also need to add the path of libdl.so typically /usr/lib/ to the first LDLIBS+= line.
I cannot answer why program A compiles with the 'same' makefile while program B fails without looking at the programs or the makefiles though.
