Usage: $ARG0 COMMAND [TARGET] [ARGS...]
|
||||
Supported TARGETs: i686 (default), x86_64, lagom
|
||||
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 [specific_test]: Runs the unit tests on the build host,
|
||||
or if specific_test is specified only this test.
|
||||
All other TARGETs: $ARG0 run [TARGET] [kernel_cmd_line]
|
||||
Runs the built image in QEMU, and optionally passes the
|
||||
kernel_cmd_line to the Kernel
|
||||
delete: Removes the build environment for the TARGET
|
||||
recreate: Deletes and re-creates the build environment for TARGET
|
||||
rebuild: Deletes and re-creates the build environment, and compiles for TARGET
|
||||
kaddr2line: $ARG0 kaddr2line TARGET ADDRESS
|
||||
Resolves the ADDRESS in the Kernel/Kernel binary to a file:line
|
||||
addr2line: $ARG0 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
|
||||
|
||||
Examples:
|
||||
$ARG0 run i686 smp=on
|
||||
Runs the image in QEMU passing "smp=on" to the kernel command line
|
||||
$ARG0 run
|
||||
Runs the image for the default TARGET i686 in QEMU
|
||||
$ARG0 run lagom
|
||||
Runs the unit tests on the build host
|
||||
$ARG0 kaddr2line i686 0x12345678
|
||||
Resolves the address 0x12345678 in the Kernel binary
|
||||
$ARG0 addr2line i686 WindowServer 0x12345678
|
||||
Resolves the address 0x12345678 in the WindowServer binary
