(Experimental)

This is the nightly version, in an attempt to explore why the release to CentOS 8 crashes.

git clone https://github.com/mozilla/gecko-dev.git
cd gecko-dev
module load python/3.8.11/gcc/pqdmnzmw
./mach bootstrap
for f in $(ls ~/.local/bin); do ln -sf ~/.local/bin/$f ~/bin/$f; done

./mach run --disable-e10s
ulimit -a
./mach clean
 

There is also GNUmakefile (extended version as in here listed below) which can be used by gmake.

# This Makefile is a shim for users with muscle memory for the "make" command.
# It's not intended for production usage or anything important.

# Default target to pull, clean, configure, build, and install
all: pull configure build install

# Module loading function (macro)
define load_modules
  if command -v module > /dev/null 2>&1; then \
    . /etc/profile.d/modules.sh; \
    module purge; \
    module load rhel8/default-icl; \
    module load python/3.8.11/gcc/pqdmnzmw; \
  else \
    echo "Module system not available. Skipping module commands."; \
  fi

# Pull the latest changes from the repository (without module loading)
pull:
	@echo "Pulling latest code..."
	git pull

# Configure the build environment
configure:
	@echo "Running configuration with prefix: $(CEUADMIN)/firefox/nightly"
	@# Ensure CEUADMIN is set or use a default value
	$(if $(CEUADMIN),,$(error "CEUADMIN environment variable not set"))
	$(call load_modules)
	./mach configure --prefix=$(CEUADMIN)/firefox/nightly

# Build the project
build:
	@echo "Building the project..."
	$(call load_modules)
	./mach build

# Install the project
install:
	@echo "Installing the project..."
	$(call load_modules)
	./mach install

# Clean the build
clean:
	@echo "Cleaning the build..."
	./mach clobber

# Mark targets that don't represent files
.PHONY: all pull configure build install clean
 

By default, the compile takes all the resources so it is a good idea to make it manageable.

ulimit -v 15728640 # Set virtual memory limit to 15 GB
export MOZCONFIG=/rds/project/rds-4o5vpvAowP0/software/gecko-dev/mozconfig
 

with mzconfig containing these lines

# Set the number of parallel jobs
mk_add_options MOZ_MAKE_FLAGS="-j5"
# Set the object directory
mk_add_options MOZ_OBJDIR=@TOPSRCDIR@/obj-@CONFIG_GUESS@
# Enable application (Firefox)
ac_add_options --enable-application=browser
# Enable optimization and disable debugging
ac_add_options --enable-optimize
ac_add_options --disable-debug

for instance, we see it translates to ` /usr/bin/gmake -C . -j5 -s -w install` near the end.
