dtrace for mac os catalina 10.15.3

Install dtrace from source on Mac OS Catalina 10.15.3

Make sure you have the xcode command line tools installed (im 90% sure this is needed, was busy trying to build the mac kernel).

xcode-select --install

dtrace-tools

Best way is to try macports. install macports https://www.macports.org/install.php

Then run:

sudo port install dtrace

I tried macports and it was broken for catalina, got it working off git though. I had to download some header files though:

• link.h
• msg.h
• dwarf.h
• elf.h
• gelf.h
• libdwarf.h
• libelf.h

I just added these to the include directory.

I also changed the include from the std library (<file.h>) to search the /usr/local/include path by replacing all e.g. <link.h> with "link.h", this repo reflects this.

Copy those files to /usr/local/include/

cp -frv include/*.h /usr/local/include/

git clone https://github.com/opensource-apple/dtrace.git
mkdir -p obj sym dst
xcodebuild install -target ctfconvert -target ctfdump -target ctfmerge \
ARCHS="x86_64" SRCROOT=$PWD OBJROOT=$PWD/obj SYMROOT=$PWD/sym \
DSTROOT=$PWD/dust

Once build succeeded you will get the following message:

INSTALL SUCCEEDED ...

You will then need to copy the binaries to /usr/local/bin

cp -frv dust/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/local/bin/* /usr/local/bin
