Total time: 5 seconds
I think some class definitions are not getting imported . How can I get rid of these errors?
EDIT:
The cause of errors seems to be these lines in build.xml file
73 <target name="compile" depends="init, build-props, protoc" description="compile the source">
74 <!-- Compile the java code from ${src} into ${build} -->
75 <javac srcdir="${src}:${gen.src}" destdir="${build.classes}"
76 debug="true" debuglevel="lines,vars,source">
77 <classpath refid="compile.classpath" />

79 </target>
Here compile.classpath may not have those class definitions .

Lua issue while compiling it with HAProxy

Here is the issue..

make: *** [haproxy] Error 1
When using the default Lua, which is 5.1.4 for CentOS7 then HAProxy can't find it. HaProxy doesn't work with 5.1.4 Lua. After updating the Lua to 5.3 or above and running the command
make -j $(nproc) TARGET=linux-glibc USE_PCRE=1 USE_PCRE_JIT=1 USE_OPENSSL=1 USE_ZLIB=1 USE_LINUX_TPROXY=1 USE_REGPARM=1 USE_LUA=1 LUA_LIB_NAME=lua5.4 USE_THREAD=1 USE_TFO=1
I still get the error above. Please have in mind that the CentOS7 is a ARM64 infrastructure. I tried to build the HAProxy and Lua on AMD64 and it went through successfully. Is it possible that this is an ARM issue ?
Okay to fix this issue first install the latest Lua package, then compile the HaProxy by using this command.
make -j $(nproc) USE_NS=1 > USE_TFO=1 > USE_ZLIB=1 > USE_LUA=1 > USE_PCRE=1 > USE_SYSTEMD=1 > USE_LIBCRYPT=1 > USE_THREAD=1 > TARGET=linux-glibc > LUA_INC=/src/lua-5.3.3/include > LUA_LIB=/src/lua-5.3.3/lib
Just outline the path of the Lua library and include directories.

I can't include the library to the linphone in Xcode

Cross compile of opencv code fails using cmake for raspberry pi

I am trying to compile an example code from ubuntu18.04 x86 machine for raspberry. My cmake and toolchain.cmake files is missing something, I am unable to make, though cmake works perfectly fine. Please help.
I have tested the cmake and output makefile for build on my pc. I works fine, but it fails during cross compile.
the code I am trying to compile can be found here: https://github.com/adamb/opencv-samples/blob/master/hello-world.cpp

I am very new to all this cross-compilation. Both systems rpi and x64 pc got opencv installation by using following command:
sudo apt-get install libopencv-dev
The log above is not complete log, but are repeated,

New RSpec runs but never gets to models

I am currently running rspec with rails 4.1.1 and ruby 2.1.1 however I'm getting a bunch of errors related to gems and such with out it even getting to the models.
This is a new version of rspec that has a spec_helper.rb as well as a rails_helper.rb
You require the rails_helper.rb in your spec with that file subsequently referencing the spec_helper.rb
I haven't made any changes to the two helper files and have just gotten started with my project. Any assistance/information would be greatly appreciated!
$ bundle exec rspec

Found the reason why this happens here: https://stackoverflow.com/a/24005972/2491655
tl;dr - running $ rails g rspec:install now adds --warnings to the .rspec file in your root directory
Part of that output is warnings (perhaps you have warnings turned on in your .rspec)
In the middle of that is
support/version_checker.rb:28:in `raise_too_low_error': You are using capybara 2.1.0. RSpec requires version >= 2.2.0. (RSpec::Support::LibraryVersionTooLowError)
Since you are using rspec 3 you actually want capybara 2.3 - version 2.2 will work but you'll get warnings about deprecated matcher syntax.

How to convert log level symbol into constant?

I am creating a new logger and want to configure the log level to equal Rails configuration value.
#logger = Logger.new(STDOUT)
#logger.level = Rails.configuration.log_level
I get an error since level expects integer and log_level is a symbol (:info). How can I convert the :info into something Logger understands (Logger::INFO)?
I tried using:
#logger.level = "Logger::#{Rails.configuration.log_level.to_s.upcase}".constantize
But constantize does not recognize the symbol:
NameError: uninitialized constant Logger::INFO
Just found it:
Logger.const_get(Rails.configuration.log_level.to_s.upcase)
