[[https://brew.sh]]

====== Development on MacOS ======
===== C/C++ =====
Using ''Homebrew'':
<code>
export HOMEBREW_NO_ANALYTICS=1
brew update
brew upgrade
brew info gcc
brew install gcc
brew cleanup
</code>

Alternative: go to the Apple App Store and install ''Xcode'' //(Apple's compiler and development tools)//. \\
Then, in a terminal:
<code>xcode-select --install</code>

<code>clang -o program program.c</code>
<code>clang++ -o program program.cc</code>
<code>g++ -std=c++11 -o program program.cpp
g++-7 -std=c++11 -o program program.cpp</code>


<code>
brew install pkg-config
brew install gettext
brew install glib
export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig:/usr/X11/lib/pkgconfig
</code>

<code>
==> Caveats
==> libffi
libffi is keg-only, which means it was not symlinked into /usr/local,
because some formulae require a newer version of libffi.

For compilers to find libffi you may need to set:
  export LDFLAGS="-L/usr/local/opt/libffi/lib"

For pkg-config to find libffi you may need to set:
  export PKG_CONFIG_PATH="/usr/local/opt/libffi/lib/pkgconfig"
</code>


=== Portable alternative for getting current time ===
<code>
#include <time.h>
#include <sys/time.h>
#ifdef __MACH__
#include <mach/clock.h>
#include <mach/mach.h>
#endif

struct timespec ts;

#ifdef __MACH__ // OS X does not have clock_gettime, use clock_get_time
clock_serv_t cclock;
mach_timespec_t mts;
host_get_clock_service(mach_host_self(), CALENDAR_CLOCK, &cclock);
clock_get_time(cclock, &mts);
mach_port_deallocate(mach_task_self(), cclock);
ts.tv_sec = mts.tv_sec;
ts.tv_nsec = mts.tv_nsec;

#else
clock_gettime(CLOCK_REALTIME, &ts);
#endif
</code>


===== Java =====
See [[https://github.com/AdoptOpenJDK/homebrew-openjdk]] where you can go and grab prebuilt openjdk binaries for macOS! \\

It’s just a case of using: \\
<code>
brew tap AdoptOpenJDK/openjdk
brew cask install <version>
</code>
Where version is:
  * ''adoptopenjdk8''
  * ''adoptopenjdk9''
  * ''adoptopenjdk10''

|	|CELLAR_HOME/jmeter/3.1/libexec/lib | |
|Configuration folder	|CELLAR_HOME/jmeter/3.1/libexec/bin | |
With the following constants: \\
''JMETER_HOME'': JMeter’s home, usually like ''/home/ubuntu/jmeter-5.x'' \\
''CELLAR_HOME'': should be ''/usr/local/Cellar''
