I am currently attempting to run an xcode project that creates a Vapor server for the ios application, however, I get an error complaining that 'openssl/conf.h' file is not found. I also get Could not build Objective-C module 'CNIOOpenSSL' on the import package, but I suspect that this is linked to the file not being found by the compiler. I have already brew installed vapor using these instructions https://stackoverflow.com/que[enter image description here]1stions/43070534/openssl-ctls-trouble-with-vapor-2, but no luck. I also installed openssl and libressl, but same results. Any suggestions on what I may be missing? I've linked screenshots of the error below.enter image description here
For me it was installing old version of openssl - openssl 1.1 and setting
echo 'export PATH="/usr/local/opt/openssl#1.1/bin:$PATH"' >> ~/.bash_profile
I am new to Ubuntu. I installed OpenCV following http://milq.github.io/install-opencv-ubuntu-debian/. Note that opencv_contrib are not installed. I had an error initially that opencv4.pc file was not found which I corrected by creating a new opencv4.pc in usr/local/lib and making appropriate changes in ~/.bashrc file. Now the error while compiling using c++ file from :
https://cv-tricks.com/installation/opencv-4-1-ubuntu18-04/.
This is the error I got:
.
I tried to locate the missing files in other locations but I was unable to find them. Please help me solve my problem.
I want to use opencv in iOS app. I cloned openCV through terminal (git clone https://github.com/opencv/opencv.git) for building opencvframework.
I used this command python opencv/platforms/ios/build_framework.py ios as per official opencv website's tutorial but i get an error that say
ERROR: Command '['xcodebuild', '-version']' returned non-zero exit

I think that might be opencv compatitibility error. I am using Xcode 8.2.1 in MAC OSX El capitan. Can somebody tell me what am i doing wrong?
There is a same issue on Github, and it looks has been fixed:
https://github.com/opencv/opencv/issues/6093
Please check:
If I add "#include " in gzguts.h, this error can be fixed.
And I have successfully build the framework under maxOS Sierra 10.12.6 and Xcode 8.3.3:
You could download it directly from link: http://onqouewnn.bkt.clouddn.com/opencv2.framework.zip
After I followed the steps on how to run cpp test on Mac OsX, there is an error when I run it in Xcode. It says that:
#include "glfw3.h <--- file not found
When I checked the folder, where I downloaded it from github, it seems that there is no glfw folder or even a file that was needed here.
So probably the files are missing. Please guide me on what could be done here to resolve this issue. Need guidance. I am using OS X version 10.9 and have Xcode 5.1.
Did you read the doc?
You need to run python download-deps.py
I want to build vlc for iOS.
My environment is MacOS 10.8.3, Xcode4.6.2 with iOS6.1 SDK.
I cloned the vlc lib form https://github.com/videolan/vlc.git, cd into the /extras/package/ios, and run the build.sh in terminal, everything goes okay except when I start making the chromaprint, I got this error:
FFTW3 lib not found. Set FFTW3_DIR to find it.
CMake Error at CMakeLists.txt:114 (message):
Neither FFmpeg with avfft.h nor FFTW3 found
This is because chromaprint needs the fft library, it will find FFMPEG and also FFTW3.
I want to use the FFMPEG for an fft calculation, so I have download a copy of ffmpeg source code and complied it,the libs and headers are in the directories: /Users/king/ffmpeg/complied/include and /Users/king/ffmpeg/complied/lib,
then I set the FFMPEG_ROOT as /Users/king/ffmpeg/complied in the cmake/modules/FindFFmpeg.cmake, just before the FIND_PATH() function.
something like : set(${FFMPEG_ROOT} /Users/king/ffmpeg/complied)
,I hope the FIND_PATH() can find the releated libs and headers, this doesn't work.
So my question is, How do i set the FFMPEG path or FFTW3_DIR for chromaprint?
Thanks in advance, I am really run out of my head!
I have same problem on VLC Windows cross build.
After I upgrade cmake to 3.22.0, this problem is fixed.
I download latest cmake source code and build.
I also download fftw3 package and extracted under /home/[username]/fftw3.
Set FFTW3_DIR to ~/fftw3 by
export FFTW3_DIR=/home/[username]/fftw3
