C++ project compiles from terminal but not from CLion after clang switch - clang

I compiled clang-14 from source on my machine and now clion won't compile my code. However, everything works as expected when I compile from terminal.
Test project:
CMakeLists.txt
cmake_minimum_required(VERSION 3.20)
project(test)
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS}
-fuse-ld=lld")
add_executable(test main.cpp)
main.cpp
#include <iostream>
int main() {
std::cout << "Hello, World!" << std::endl;
return 0;
}
I use default project setup with path/to/clang and path/to/clang++ as C and C++ compilers respectively in clion.
When I compile, I get the following error.
clang-14: error: no input files
make[3]: *** [CMakeFiles/test.dir/build.make:93: test] Error 1
make[2]: *** [CMakeFiles/Makefile2:83: CMakeFiles/test.dir/all] Error 2
make[1]: *** [CMakeFiles/Makefile2:90: CMakeFiles/test.dir/rule] Error 2
make: *** [Makefile:124: test] Error 2
To compile from terminal I do:
mkdir build
cd build
CC=path/to/clang CXX=path/to/clang++ cmake ..
make
What am I missing?

Make does not detect opencv_contrib even though I have it installed

I am trying to get this running https://github.com/Katou2/Optical_Flow_GPU_Opencv3 but am facing an issue where make does not detect my opencv_contrib module. Here are the steps that I have done up till cmake.
conda create -n opticalflow python=3.6 anaconda
conda activate opticalflow
git clone https://github.com/Katou2/Optical_Flow_GPU_Opencv3
cd Optical_Flow_GPU_Opencv3
mkdir build
cd build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D WITH_CUDA=ON -D OPENCV_EXTRA_MODULES_PATH=../../opencv_contrib/modules -D BUILD_TIFF=ON ..
And this is the output that I get with no error.

The problem comes when I run make.

So the error mentions that the file opencv2/cudaoptflow.hpp is not found and I read through https://github.com/open-mmlab/mmaction/issues/39 says that the error is due to the opencv_contrib module not having been installed. However, I am certain that I already have opencv_contrib installed because I have this command executed.
pip install opencv-contrib-python
and have also verified it as I am able to call the cv2.xfeatures2d method which requires opencv_contrib to run.
import cv2
help(cv2.xfeatures2d) # cv2.xfeatures2d requires opencv_contrib

fbthrift: No generator named 'cpp2' could be found after (seemingly) successful build

I'm trying to install crnn which requires fblualib on Ubuntu 18.04 LTS. While building TH++, an error occured (Complete build print attached below):
[ 10%] Building CXX object CMakeFiles/thpp.dir/Storage.cpp.o
In file included from /home/huiji/Downloads/thpp-master/thpp/Storage.cpp:11:0:

#include **<thpp/if/gen-cpp2/Tensor_types.h>**
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
If I build thpp without using fbthrift and folly by running THPP_NOFB=1 ./build.sh in the thpp directory, the build would be successful (I have thpp files in torch/install/include and torch/install/lib). However, if I move on and build fblualib, an almost identical error occurs:

^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
I figure that there may be something wrong with my fbthrift. Then I tried the following commands under directory "thpp/if/". It seems that my fbthrift can't generate a cpp2-format file, but can generate a cpp/py file, awhile my python thrift_compiler can only generate an errored cpp2-format file.
$ thrift --gen cpp2 Tensor.thrift

$ python -m thrift_compiler.main --gen py Tensor.thrift

By the way, my fbthrift install seemed successful except the python package thrift_compiler was not installed correctly. I've followed GitHubGS's suggestion. That seem to have worked (I can now import thrift_compiler in python, below is what I did) but as you can see, it is not really working.
1.modify /thrift/compiler/CMakefile.txt by inserting these lines
set(CMAKE_CXX_FLAGS "-fPIC")
set(CMAKE_C_FLAGS "-fPIC")
2.rebuild/reinstall fbthrift(must step)
3.run your command under /fbthrift/thrift/compiler/py
g++ -I /usr/include/python2.7 -I ../../.. -std=c++14 -fpic -shared -o frontend.so compiler.cc -lboost_python -lpython2.7 -L/build/lib -lcompiler_base -lcompiler_ast -lboost_system -lboost_filesystem -lssl -lcrypto
sudo cp frontend.so /usr/local/lib/python2.7/dist-packages/thrift_py-0.9.0-py2.7.egg/thrift_compiler
Any ideas/suggestions would be greatly appreciated.

Use thrift1 and mstch_cpp2 instead. It works for me!
See https://github.com/facebook/fbthrift/issues/271 and $THRIFT_INCLUDE is /usr/local/include/thrift/ in my system.
As one of the above answer mentioned, after building fbthrift successfully, you get bin/thrift1 binary in your build folder. You can then use the output thrift1 with generator mstch_cpp2.
./build/bin/thrift1 --gen mstch_cpp2 --templates ./thrift/compiler/generate/templates --out /tmp/ ./thrift/example/if/chatroom.thrift

Error in compiling using gsoap

I am trying to compile the files after generating from these steps:-
(1) wsdl2h -o calc.h http://www.genivia.com/calc.wsdl
(2) soapcpp2 -j -CL calc.h
(3) Creating a main.cpp with the following code:-
#include "calc.nsmap" // XML namespace mapping table (only needed once at the global level)
#include "soapcalcProxy.h" // the proxy class, also #includes "soapH.h" and "soapStub.h"
int main()
{
calcProxy calc;
double sum;
if (calc.add(1.23, 4.56, sum) == SOAP_OK)
std::cout << "Sum = " << sum << std::endl;
else
calc.soap_stream_fault(std::cerr);
calc.destroy(); // same as: soap_destroy(calc.soap); soap_end(calc.soap);
}
After it I compile issuing the command:-
g++ -o calcclient main.cpp soapcalcProxy.cpp soapC.cpp -lgsoap++
I get the following errors:-
/tmp/ccA5Ergj.o: In function `soap_ignore_element(soap*)':
soapC.cpp:(.text+0x112d): undefined reference to `soap_ignore'
/tmp/ccA5Ergj.o: In function `soap_putelement':
soapC.cpp:(.text+0x149b): undefined reference to `soap_element_empty'
collect2: error: ld returned 1 exit status
Please help in compiling.
I solved this. I was thinking the lib is in /usr/lib but it was in /usr/local/lib. I included -L/usr/local/lib while compiling, and it worked.

Error: File format not recognized

I'm using a Raspberry Pi 2 running Ubuntu MATE 15.10 to work on a project.
I'm trying to run a makefile and got this error
/home/dpanagou/Quadrotors/Vicon/libs/libViconDataStreamSDK_CPP.so: file not recognized: File format not recognized
collect2: error: ld returned 1 exit status
Makefile:8: recipe for target '../bin/Vicon_state' failed

make[1]: Leaving directory '/home/dpanagou/Quadrotors/HLP/Vicon'
Makefile:40: recipe for target 'Vicon' failed
make: *** [Vicon] Error 2
I've also tried make clean before make.
From research, a lot of people have suggested that the object file might be corrupted. So I downloaded new files from the developer and ran the makefile again. I still get the same error.
Here is my makefile:
CUR_DIR = $(shell pwd)
CFLAGS = `pkg-config --cflags lcm`
LDFLAGS = `pkg-config --libs lcm` ../src/filter_util.o ../src/util.o
vicon_lib = $(CUR_DIR:%/HLP/Vicon=%/Vicon/libs)
../bin/Vicon_state:
g++ $(CFLAGS) Vicon_state_data.cpp -o ../bin/Vicon_state -Wl,- rpath=../../Vicon/libs -L$(vicon_lib) -lViconDataStreamSDK_CPP -lDebugServices $(LDFLAGS)
Please help with specific instructions as I am very new to Linux and programming.
Check the format of the file with the "file" command, and compare it to the format of any .so that comes with rpi.
I'm not 100% sure, but might it be that the library is for raspbian with its v6 compatible HF vs generic V7-only HF in debian?

Error when linking C executable to OpenCV

I'm compiling OpenCV under Ubuntu 13.10 using cMake.
i've already compiled c++ programs and they works well.
now i'm trying to compile a C file using this cMakeLists.txt
cmake_minimum_required (VERSION 2.8)
project (hello)
find_package (OpenCV REQUIRED)
add_executable (hello src/test.c)
target_link_libraries (hello ${OpenCV_LIBS})
here is the test.c file:
#include <stdio.h>
#include <stdlib.h>
#include <opencv/highgui.h>
int main (int argc, char* argv[])
{
IplImage* img = NULL;
const char* window_title = "Hello, OpenCV!";
if (argc < 2)
{
fprintf (stderr, "usage: %s IMAGE\n", argv[0]);
return EXIT_FAILURE;
}
img = cvLoadImage(argv[1], CV_LOAD_IMAGE_UNCHANGED);
if (img == NULL)
{
fprintf (stderr, "couldn't open image file: %s\n", argv[1]);
return EXIT_FAILURE;
}
cvNamedWindow (window_title, CV_WINDOW_AUTOSIZE);
cvShowImage (window_title, img);
cvWaitKey(0);
cvDestroyAllWindows();
cvReleaseImage(&img);
return EXIT_SUCCESS;
}
it returns me this error whene running cmake . then make to the project:

I had the same errors and it worked with me
Edit your CMakeLists.txt as follows:
cmake_minimum_required(VERSION 2.8)
project(test)
find_package( OpenCV REQUIRED )
add_executable( test test.c )
target_link_libraries( test ${OpenCV_LIBS} )
Then, $ cmake .
Then $ make and finally $./test
