How to build

• You need a patched GHC 8.1 from the repo until the project is merged into GHC master.

• Clone and boot the repo:

git clone https://github.com/NCrashed/live-profile-monitor.git --recursive
cd live-profile-monitor
cd ghc-events && git checkout incremental && cd ..

Cabal >= 1.24

• Initalize cabal environment (note, you need Cabal and cabal-install not lower than 1.24.0.0 version):

cabal new-configure --enable-tests

• Compile:

cabal new-build

• Test:

./tests.sh

Stack

• Tell stack to use system wide GHC:

stack --compiler=ghc-8.1 install

• Test:

stack build --test --compiler=ghc-8.1 --no-run-tests
stack test live-profile-monitor:test-monitor --compiler=ghc-8.1 --test-arguments="./.stack-work/dist/*/Cabal-*/build/test-leech/test-leech"
ghc-events inc test.eventlog
