Notes on building JTDX for Mac

Building from Source on Apple Mac


You  will need  Xcode, MacPorts, HomeBrew, CMake  and, Qt.   The Xcode  install

instructions are included in the MacPorts documentation.



There are two parts to install Xcode one is just to install from the Mac AppStore.  Then also from 

the command line from the MacPorts website to install needed Xcode utils run the following command

$ xcode-select –install

You will need to agree to the Xcode license agreement by issuing the following command:

$ sudo xcodebuild -license



Install Homebrew with the following command.

$ /bin/bash -c “$(curl -fsSL”

$ (echo; echo ‘eval “$(/usr/local/bin/brew shellenv)”‘) >> /Users/michaelmorgan/.zprofile

$ eval “$(/usr/local/bin/brew shellenv)”

Then install the following:

$ brew install gcc@9



Install MacPorts from instructions here:

The ports that need to be installed are:

$ sudo port install autoconf

$ sudo port install automake

$ sudo port install libtool

$ sudo port install pkgconfig

$ sudo port install texinfo

$ sudo port install fftw-3-single +gcc9

$ sudo port install asciidoc

$ sudo port install asciidoctor

$ sudo port install libusb-devel

$ sudo port install boost

$ sudo port install qt5

$ sudo port install qt5-qtmultimedia

$ sudo port install qt5-qtwebsockets



First fetch hamlib from the repository, in this case my fork of Hamlib

3 until the official repository has all the fixes we need:

$ mkdir -p ~/hamlib-prefix/build

$ cd ~/hamlib-prefix

$ git clone git:// src

$ cd src

$ ./bootstrap

To build:

$ cd ~/hamlib-prefix/build

$ ../src/configure \

   –enable-shared \

   –disable-static \

   –disable-winradio \

   –prefix=$HOME/hamlib-prefix \

   –without-readline \

   –without-indi \

   –without-cxx-binding \

   CFLAGS=”-g -O2 -mmacosx-version-min=10.13 -I/opt/local/include” \

   LIBUSB_LIBS=”-L/opt/local/lib -lusb-1.0″

$ make

$ make install-strip

The   above  commands   will  build   hamlib  and   install  it   into

~/hamlib-prefix. If `make install-strip` fails, try `make install`.



Download the latest CMake universal 64-bit DMG from  open the  DMG then  drag and  drop the

application bundle onto the supplied /Applications link.

To  complete  the  install  process  you need  to  run  the  CMake-gui

application as root from a terminal shell as follows:

$ sudo “/Applications/” –install



First fetch the source from the repository:

$ mkdir -p ~/jtdx-prefix/build

$ cd ~/jtdx-prefix

$ git clone git:// src

$ cd ~/jtdx-prefix/build

For my Intel Mac:

$ FC=/usr/local/Cellar/gcc@9/9.5.0/bin/gfortran-9 \

   cmake \

   -D CMAKE_PREFIX_PATH=”/opt/local/libexec/qt5;~/hamlib-prefix;/opt/local” \

   -D CMAKE_INSTALL_PREFIX=~/jtdx-prefix \

   -D CMAKE_OSX_SYSROOT=/Applications/ \


For my M1 Mac:

FC=gfortran \

   cmake \

   -D CMAKE_PREFIX_PATH=”/opt/local/libexec/qt5;~/hamlib-prefix;/opt/local” \

   -D CMAKE_INSTALL_PREFIX=~/jtdx-prefix \

   -D CMAKE_OSX_SYSROOT=/Applications/ \


Substitute the  Mac OS X SDK  version you have installed  in the above

command if you have a different version from 10.15.

Also make sure you have the path to right Fortran in the first line above.

The CMAKE_PREFIX_PATH variable specifies where CMake should look first

for other packages, the two  elements may be different depending where

you have installed Qt and what version you have (~/local/qt-macx-clang

if  you have  built  Qt from  sources  as described  above  in the  Qt

section) and where you installed  Hamlib (i.e.  the –prefix configure

option above in the Hamlib section).

If you already have the fftw3-dev  package installed on your system it

may well get selected in preference to  the one you built above in the

MacPorts installation.  It is  unlikely that  a prior  installation of

libfftw3f is  correctly configured  for use in  a JTDX  package, the

CMAKE_PREFIX_PATH above  is augmented  with the  MacPorts installation

location  (/opt/local)  to  ensure  the  correct  libfftw3f.dylib  and

headers are located.

To build:

$ cmake –build .

$ cmake –build . –target install

$ cmake –build . –target package — -kj

sudo mkdir gcc-devel

sudo ln /opt/homebrew/lib/gcc/12/libquadmath.0.dylib /opt/local/lib/gcc-devel/libquadmath.0.dylib

sudo ln /opt/homebrew/lib/gcc/12/libgcc_s.1.1.dylib /opt/local/lib/gcc-devel/libgcc_s.1.1.dylib

which installs the JTDX application bundle into ~/jtdx-prefix

Updating and Rebuilding Hamlib


From  time  to time  new  fixes  will be  pushed  to  the Hamlib  fork

repository integration branch. To pick them up type:

$ cd ~/hamlib-prefix/src

$ git pull

To rebuild hamlib with the changed sources:

$ cd ~/hamlib-prefix/build

$ make

$ make install-strip

Updating and Rebuilding JTDX


To update to the latest sources type:

$ cd ~/jtdx-prefix/src

$ git pull

$ cd ~/jtdx-prefix/build

$ cmake –build .

$ cmake –build . –target install

codesign -s “Mac Developer: charles morgan (G89EBN4PSS)” –deep -f ~/jtdx-prefix/
