I am working with android native and use CMake. I need to use a cv::imwrite method from OpenCV, but when I use it in my code I get such an error:
error: undefined reference to cv::imwrite
It seems that I added everything right in CMakeList.txt
...
set(pathToOpenCv $ENV{OPEN_CV_PATH})
include_directories(${pathToOpenCv}/sdk/native/jni/include)
add_library(lib_opencv SHARED IMPORTED)
set_target_properties(lib_opencv PROPERTIES IMPORTED_LOCATION
${pathToOpenCv}/sdk/native/libs/${CMAKE_ANDROID_ARCH_ABI}/libopencv_java3.so)
target_link_libraries(decoder_engine_lib
mediandk
oboe::oboe
android
lib_opencv
${log-lib}
)
...
What am I missing here? Why I get this error in spite file is exist and #include added?

I am trying this example to use PCL with GPU and get the error
~/gpu-pcl/main.cpp:85: error: missing template arguments before ‘gec’
pcl::gpu::EuclideanClusterExtraction gec;
I have tried that example with pcl-1.11.1 and it worked well .But when updated to pcl-1.12.1, I get that error.
My work environment:
Ubuntu 18.04,
with Cmake version 3.20,
Is there anything that I have missed out??
In the documentation of pcl1.12:
template
class pcl::gpu::EuclideanClusterExtraction< PointT >
EuclideanClusterExtraction is a template class, thus the type of point of the point cloud is needed in the position of PointT, for example, PointXYZ.[https://pointclouds.org/documentation/classpcl_1_1gpu_1_1_euclidean_cluster_extraction.html#details]
I am upgrading the dependencies of my react-native application from 0.53 to 0.59.
But I am facing the below error while trying to build it using ./gradlew assembleRelease.
#babel/template placeholder "$1": Property expression of ExpressionStatement expected node to be of a type ["Expression"] but instead got "TSModuleBlock".

I would like to know if there is possiblity to solve this build error.
thank you in advance.
This might probably due to a namespace being exported which only contain interfaces/types (Not actual classes/functions/objects but type declarations).
A quick fix is to add declare to the exported namespace.
export declare namespace SomeNameSpace
instead of
export namespace SomeNameSpace
I am using joint js 3.1.1 version and graphlib 2.1.8 version.
I have a code in my app to check cyclic reference in graph. For that purpose I have written below code
graphlib.alg.findCycles(graph.toGraphLib())
This line gives following error
Uncaught Error: The the "graphlib" utility is a mandatory dependency.

I have imported graphlib in my file also. But still getting following error.
I have imported graphlib as
import graphlib from 'graphlib'
You can try by passing graphlib as a part of the options object, as follows-
graph.toGraphLib({graphlib: graphlib})
Writing an iOs7 project, with Xcode 5
I have the following simple code
NSString* inflation=#"test'", *import=#"";
if ([inflation length]>0){
import=[import stringByAppendingFormat:#"\nExports %#",inflation];
}
And I keep getting this error when I try to compile:
Module 'stringByAppendingFormat' not found
LLVM uses import for importing modules (currently an experimental feature but seems to be enabled by default in Xcode). Have a look at the docs.
To resolve your issue, just rename the variable, or compile with "-fno-modules".
There is not an issue with this code, so don't blame ios7 :P
Just change your variable name.
NSString* inflation=#"test'", *importString=#"";
if ([inflation length]>0){
importString=[importString stringByAppendingFormat:#"\nExports %#",inflation];
}

I am getting this error even i have already imported header file of "CustomerViewController.h" in "Kunden.h"
Help me!
Make sure that CustomerNameViewController.m (implementation file for CustomerNameViewController class) is added to a target you're building.
