I am trying to install avr-gcc-libc on NixOS, but run into a build error.
I try to install with the command
nix-env -iA nixos.avrgcclibc
The output this produces is very long and terminates with

All files compile generating respective .o files except the main.cc. So I compile it using this command
g++ -O2 -Wno-deprecated -g -c -o main.o main.cc
Now the main.o file compiles and main.o is generated
I then run it using ./main.o and get Permission denied
So I get rid of this error by chmod 755 ./*
Now running the main.o gives this error
bash: ./main.o cannot execute binary file Exec format error
Through my research I found out that this error is because of the mismatch in arhitecture and file type.
file main.o outputs x86-64 and uname -m outputs x86_64
I cannot figure out the problem.
Any help would be greatly appreciated! Thank you!
You are trying to execute an object file. Object files like main.o are not executable. They only contain part of the code required to form an exectuable.
You need to run main (or maybe test.out), which is the actual executable.
The permission warnings were telling you the same thing (that main.o is not executable), but you overwrote that with chmod.
main should be created by make assuming there are no compilation/linking errors if you use make main or test.out if you use make or make test.out. The linker invocation is given in the main:/test.out: target of the Makefile. If make generates compiler or linker errors, then repeating the same commands manually is not going to fix it. Fix the code or Makefile instead.
Also note that the warnings/errors are there for a reason. Since C++11, you are not allowed to cast string literals to char*, only to const char*. This was deprecated already in C++03. Circumventing that rule is only going to cause you trouble in the future. Fix your code instead of adding -Wno-deprecated.
I am using GitHub in-paint library https://github.com/cheind/inpaint in android studio
and trying to call jni fuction of inpainter in main activity but it is not resolving or getting recognized.
C++ is new to me so i am having issue.
in criminisi_inpainter.cpp file
there is this function
void inpaintCriminisi(
cv::InputArray image,
cv::InputArray targetMask,
cv::InputArray sourceMask,
int patchSize)
{
CriminisiInpainter ci;
ci.setSourceImage(image.getMat());
ci.setSourceMask(sourceMask.getMat());
ci.setTargetMask(targetMask.getMat());
ci.setPatchSize(patchSize);
ci.initialize();
while (ci.hasMoreSteps()) {
ci.step();
}
ci.image().copyTo(image.getMat());
}
this native function i have to call in main activity
public native void inpaintCriminisi( ? , ? ,? , int z);
The issue is i do not understand what parameters would be provided here in main activity (JAVA)
In nativelib.cpp i am exporting jnicall function i give object parameters which is not exact parameters that should be defined.
extern "C"
JNIEXPORT void JNICALL
Java_com_example_raweeda_applicationc_MainActivity_inpaintCriminisi(JNIEnv *env, jobject instance,
jobject a, jobject b, jobject c,
jint xl) {
// TODO
inpaintCriminisi(x,y,z,xl);
parameters are not object it just an example
}
this is the error i am recieving

I've been attempting to build wxWidgets 3.1.0 in Cygwin. I followed the process described in the install.txt, summarized below:
cd $WXWIN

I have also tried a couple other flags for configure such as --with-X11, as suggest by this guide. The error I keep receiving, however, is the following:

I would very much appreciate some suggestions on this!
This is most likely already fixed in wx's git master by this commit. But you can work around the problem by using configure --disable-xlocale.
I try to substitute the syslog function in such a manner:
#include <cstdio>
#include <cstdarg>
void syslog_printf(int level, char* format, ...)
{
va_list params;
va_start(params, format);
vprintf(format, params);
printf("\n");
va_end(params);
}
#define syslog(...) syslog_printf(__VA_ARGS__)
#include <modbus/modbus.c>
This is a listing of my modbus.cpp file. The modbus.c is there too, but I can't modify it because it used in several places. The modbus.cpp compiled right but the linker reports that it can't find the syslog_printf function.
The question is simple: why?

When i try to add iperf3 to the only C++ project all is good. This error exist only in Qt project. Is any idea?
I have the same problem with iperf3 and Qt. Basically it seems that you have to use similar compilation for iperf3 library and your project (both gcc or both g++).
Let us know how it goes. Or share your solution if already done.

or do the following for iperf_api.h
extern "C" {
#include <iperf_api.h>
}
