I've bin trying to integrate Apache and with Django.
I downloaded the mod_wsgi-3.4 folder from the net and tried running the ./configure command from git bash.
I'm using dev c++ as my c compiler.
I get the following errors:
./configure: line 1877: apxs: command not found ln: creating symbolic link 'Makefile.in' to 'posix-apX.mk.in': No such file directory configure: creating ./config.status config.status:error: cannot find input file: Makefile.in
Can someone help me with this?
You can specify the location of apxs
./configure --with-apxs=/usr/local/apache/bin/apxs

I think I read pretty much most of the guides on setting up tensorflow, tensorflow-hub, object detection on Mac M1 on BigSur v11.6. I managed to figure out most of the errors after more than 2 weeks. But I am stuck at OpenCV setup. I tried to compile it from source but seems like it can't find the modules from its core package so constantly can't make the file after the successful cmake build. It fails at different stages, crying for different libraries, despite they are there but max reached 31% after multiple cmake and deletion of the build folder or the cmake cash file. So I am not sure what to do in order to make successfully the file.
I git cloned and unzipped the opencv-4.5.0 and opencv_contrib-4.5.0 in my miniforge3 directory. Then I created a folder "build" in my opencv-4.5.0 folder and the cmake command I use in it is (my miniforge conda environment is called silicon and made sure I am using arch arm64 in bash environment):
cmake -DCMAKE_SYSTEM_PROCESSOR=arm64 -DCMAKE_OSX_ARCHITECTURES=arm64 -DWITH_OPENJPEG=OFF -DWITH_IPP=OFF -D CMAKE_BUILD_TYPE=RELEASE -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/Users/adi/miniforge3/opencv_contrib-4.5.0/modules -D PYTHON3_EXECUTABLE=/Users/adi/miniforge3/envs/silicon/bin/python3.8 -D BUILD_opencv_python2=OFF -D BUILD_opencv_python3=ON -D INSTALL_PYTHON_EXAMPLES=ON -D INSTALL_C_EXAMPLES=OFF -D OPENCV_ENABLE_NONFREE=ON -D BUILD_EXAMPLES=ON /Users/adi/miniforge3/opencv-4.5.0
So it cries like:
[ 20%] Linking CXX shared library ../../lib/libopencv_core.dylib
[ 20%] Built target opencv_core
make: *** [all] Error 2
or also like in another tries was initially asking for calib3d or dnn but those libraries are there in the main folder opencv-4.5.0.
The other way I try to install openCV is with conda:
conda install opencv
But then when I test with
python -c "import cv2; cv2.__version__"
it seems like it searches for the ffmepg via homebrew (I didn't install any of these via homebrew but with conda). So it complained:
Traceback (most recent call last):
File "<string>", line 1, in <module>
File "/Users/adi/miniforge3/envs/silicon/lib/python3.8/site-packages/cv2/__init__.py", line 5, in <module>

Referenced from: /Users/adi/miniforge3/envs/silicon/lib/python3.8/site-packages/cv2/cv2.cpython-38-darwin.so
Reason: image not found
Though I have these libs, so when I searched with: find /usr/ -name 'libavcodec.58.dylib' I could find many locations:

ln: /opt/homebrew/opt/ffmpeg/lib/libavcodec.58.dylib: No such file or directory
One of the guides said to install homebrew also in arm64 env, so I did it with:
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
export PATH="/opt/homebrew/bin:/usr/local/bin:$PATH"
alias ibrew='arch -x86_64 /usr/local/bin/brew' # create brew for intel (ibrew) and arm/ silicon
Not sure if that is affecting it but seems like it didn't do anything because still uses /opt/homebrew/ instead of /usr/local/.
So any help would be highly appreciated if I can make any of the ways work. Ultimately I want to use Tenserflow Model Zoo Object Detection models. So all the other dependencies seems fine (for now) besides either OpenCV not working or if it is working with conda install then it seems that scipy and scikit-learn don't work.
In my case I also had lot of trouble trying to install both modules. I finally managed to do so but to be honest not really sure how and why. I leave below the requirements in case you might want to recreate the environment that worked in my case. You should have the conda Miniforge 3 installed :

I am an (absolute) beginner with libwebsockets (and cmake), and am trying to build one of the minimal examples from libwebsockets.org:
"lws minimal ws server + permessage-deflate echo"
at
https://libwebsockets.org/git/libwebsockets/tree/minimal-examples/ws-server/minimal-ws-server-echo
I have installed libwebsockets-dev (sudo apt install libwebsockets-dev) and cmake (sudo apt install cmake).
The example page tells me to build the example (two .c files and CMakeLists.txt) using
$ cmake . && make
The build fails with the following message:
CMake Error at CMakeLists.txt:3 (find_package):
Could not find a package configuration file provided by "libwebsockets"
with any of the following names:
libwebsocketsConfig.cmake
libwebsockets-config.cmake
Add the installation prefix of "libwebsockets" to CMAKE_PREFIX_PATH or set
"libwebsockets_DIR" to a directory containing one of the above files. If
"libwebsockets" provides a separate development package or SDK, be sure it
has been installed.
-- Configuring incomplete, errors occurred!
See also "/home/user/ws/CMakeFiles/CMakeOutput.log".
I cannot find either of the .cmake files in my system (they are evidently not provided as part of package libwebsockets-dev.)
What am I missing?
Thank you!
Thank you, Tsyvarev, you are correct.
The solution was to build libwebsockets from github repository, use that instead of libwebsocket-dev installed from ubuntu 18.04.
I am getting the following error :
CMake Error at CMakeLists.txt:9 (BISON_TARGET):
Unknown CMake command "BISON_TARGET".
when I run the command :
cmake .. -GNinja
Please tell me what to do. I tried searching on google a lot and thus came up with the additions and finally ran the command :
cmake .. -D LLVM_DIR=/usr/lib/llvm-5.0/cmake/ -D FLEX_EXECUTABLE=/usr/local/Cellar/flex/2.5.37/bin/ -D FLEX_INCLUDE_DIR=/usr/local/Cellar/flex/2.5.37/include/ -D BISON_EXECUTABLE=/usr/bin/bison
but it still shows the same error :(.
Please someone help.
Your error is occurring because the BISON_TARGET function definition has not yet been supplied. This method, as commented, is supplied by FindBISON. The error indicates that either Bison was not found on your system (hopefully, you have it installed), or cmake was ran from the wrong directory. Bison is included in the top-level CMake file via:
find_package(BISON REQUIRED)
This line to include Bison must be called before using the BISON_TARGET CMake function. The LLReve instructions for compiling this repository are explicit about which directory to run the build commands in:
Go to the llreve directory and run
cd reve
mkdir build
cd build
cmake .. -GNinja
ninja
This would run on the CMake file in the llreve/reve directory, not the llreve/reve/reve directory. Please ensure you are running CMake from the correct location, as not running cmake on the top-level CMake file will often yield errors.
I'm trying to compile the "Source Code (.c)" example from this tutorial.
I have installed mruby using rbenv: rbenv install mruby-1.2.0
I get an error when trying to compile the program:
$ gcc -std=c99 -Imruby/include test_program.c -o test_program
test_program.c:1:10: fatal error: 'mruby.h' file not found
#include "mruby.h"
^
1 error generated.
How am I supposed to reference the mruby library when installing via rbenv/ruby-build?
Seems like rbenv install mruby-1.2.0 doesn't install header files of mruby(it's only a dump of build/host directory after mruby is built):
% ls $(rbenv prefix mruby-1.2.0)
LEGAL bin lib mrbgems mrblib src
You need
# get mruby's code
git clone https://github.com/mruby/mruby.git mruby
# build mruby
cd mruby && rake
# go back to directory of `test_program.c`
cd ..
before test_program.c's compilation instead.
And you need mruby/build/host/lib/libmruby.a -lm compile options too.
add -lm
in mruby is /include directory in my source is possible -I mruby_directory/include
next add ~/mruby/build/host/lib/libmruby.a
I want to build Kurento Media Server against latest Fedora.
However, CMake fails to configure sources:
Could not find a package configuration file provided by "KurentoHelpers"
with any of the following names:
KurentoHelpersConfig.cmake
kurentohelpers-config.cmake
I installed kms-cmake-utils, as suggested, to /usr/local/. However, I still have this error, even if I set CMAKE_PREFIX_PATH to the folder where kms-cmake-utils's install target put .cmake modules.
In fact, there is no KurentoHelpersConfig.cmake file in kms-cmake-utils.
How can I configure Kurento for Fedora?
Try installing to /usr instead of /usr/local because cmake is looking for modules in /usr/share
Executing cmake like this should fix the problem:
cmake .. -DCMAKE_PREFIX_PATH=/usr
You should append path of KurentoHelpersConfig.cmake to CMAKE_MODULE_PATH, do that by adding this line to CMakeLists.txt :
SET(CMAKE_MODULE_PATH ${CMAKE_MODULE_PATH} "/usr/local/share/cmake-3.5/Modules")
It seems something wrong in cmake, it cannot read external CMAKE_MODULE_PATH, so I force set into its arguments line ( Ubuntu server x86_64 used), pay attention -DCMAKE_MODULE_PATH=$CMAKE_MODULE_PATH.
HOME=`pwd`
BUILD=$HOME/build
export CMAKE_MODULE_PATH=$BUILD/usr/local/share/cmake-3.5/Modules
mkdir -p build
cd build
cmake -DCMAKE_PREFIX_PATH=$HOMEDIR/build -DCMAKE_MODULE_PATH=$CMAKE_MODULE_PATH ..
make DESTDIR=$HOMEDIR/build install
