GCC's build fails in `libisl`'s configure step if `CC` is set to Homebrew Clang with the message "Link Time Optimisation is not supported". This is likely due to the fact that it tries to use ranlib from Xcode, which is not compatible with the newer LLVM version's bitcode format. The toolchain build runs after `pick_host_compiler` is called, which selects Homebrew Clang if the installed Xcode version is too old. We need to unset `CC` and `CXX` for the toolchain build to sidestep the issue.

Usage: $NAME COMMAND [TARGET] [TOOLCHAIN] [ARGS...]
|
|
Supported TARGETs: aarch64, x86_64, lagom. Defaults to SERENITY_ARCH, or x86_64 if not set.
|
|
Supported TOOLCHAINs: GNU, Clang. Defaults to SERENITY_TOOLCHAIN, or GNU if not set.
|
|
Supported COMMANDs:
|
|
build: Compiles the target binaries, [ARGS...] are passed through to ninja
|
|
install: Installs the target binary
|
|
image: Creates a disk image with the installed binaries
|
|
run: TARGET lagom: $NAME run lagom LAGOM_EXECUTABLE [ARGS...]
|
|
Runs the Lagom-built LAGOM_EXECUTABLE on the build host, e.g.
|
|
'shell' or 'js', [ARGS...] are passed through to the executable
|
|
All other TARGETs: $NAME run [TARGET] [KERNEL_CMD_LINE]
|
|
Runs the built image in QEMU, and optionally passes the
|
|
KERNEL_CMD_LINE to the Kernel
|
|
gdb: Same as run, but also starts a gdb remote session.
|
|
TARGET lagom: $NAME gdb lagom LAGOM_EXECUTABLE [-ex 'any gdb command']...
|
|
Passes through '-ex' commands to gdb
|
|
All other TARGETs: $NAME gdb [TARGET] [KERNEL_CMD_LINE] [-ex 'any gdb command']...
|
|
If specified, passes the KERNEL_CMD_LINE to the Kernel
|
|
Passes through '-ex' commands to gdb
|
|
test: TARGET lagom: $NAME test lagom [TEST_NAME_PATTERN]
|
|
Runs the unit tests on the build host, or if TEST_NAME_PATTERN
|
|
is specified tests matching it.
|
|
All other TARGETs: $NAME test [TARGET]
|
|
Runs the built image in QEMU in self-test mode, by passing
|
|
system_mode=self-test to the Kernel
|
|
delete: Removes the build environment for TARGET
|
|
recreate: Deletes and re-creates the build environment for TARGET
|
|
rebuild: Deletes and re-creates the build environment, and compiles for TARGET
|
|
kaddr2line: $NAME kaddr2line TARGET ADDRESS
|
|
Resolves the ADDRESS in the Kernel/Kernel binary to a file:line
|
|
addr2line: $NAME addr2line TARGET BINARY_FILE ADDRESS
|
|
Resolves the ADDRESS in BINARY_FILE to a file:line. It will
|
|
attempt to find the BINARY_FILE in the appropriate build directory
|
|
rebuild-toolchain: Deletes and re-builds the TARGET's toolchain
|
|
rebuild-world: Deletes and re-builds the toolchain and build environment for TARGET.
|
|
copy-src: Same as image, but also copies the project's source tree to ~/Source/serenity
|
|
in the built disk image.
|
|
|
|
|
|
Examples:
|
|
$NAME run x86_64 GNU smp=on
|
|
Runs the image in QEMU passing "smp=on" to the kernel command line
|
|
$NAME run x86_64 GNU 'init=/bin/UserspaceEmulator init_args=/bin/SystemServer'
|
|
Runs the image in QEMU, and run the entire system through UserspaceEmulator (not fully supported yet)
|
|
$NAME run
|
|
Runs the image for the default TARGET x86_64 in QEMU
|
|
$NAME run lagom js -A
|
|
Runs the Lagom-built js(1) REPL
|
|
$NAME test lagom
|
|
Runs the unit tests on the build host
|
|
$NAME kaddr2line x86_64 0x12345678
|
|
Resolves the address 0x12345678 in the Kernel binary
|
|
$NAME addr2line x86_64 WindowServer 0x12345678
|
|
Resolves the address 0x12345678 in the WindowServer binary
|
|
$NAME gdb x86_64 smp=on -ex 'hb *init'
|
|
Runs the image for the TARGET x86_64 in qemu and attaches a gdb session
|
|
setting a breakpoint at the init() function in the Kernel.
