 ## Getting Started

-You can start by obtaining a release of our `cosmocc` compiler from
-<https://cosmo.zip/pub/cosmocc/>.
+If you're doing your development work on Linux or BSD then you need just
+five files to get started. Here's what you do on Linux:

 ```sh
-mkdir -p cosmocc
-cd cosmocc
-wget https://cosmo.zip/pub/cosmocc/cosmocc.zip
-unzip cosmocc.zip
+wget https://justine.lol/cosmopolitan/cosmopolitan-amalgamation-1.0.zip
+unzip cosmopolitan-amalgamation-1.0.zip
+printf 'main() { printf("hello world\\n"); }\n' >hello.c
+gcc -g -Os -static -nostdlib -nostdinc -fno-pie -no-pie -mno-red-zone \
+  -fno-omit-frame-pointer -pg -mnop-mcount \
+  -o hello.com.dbg hello.c -fuse-ld=bfd -Wl,-T,ape.lds \
+  -include cosmopolitan.h crt.o ape.o cosmopolitan.a
+objcopy -S -O binary hello.com.dbg hello.com
 ```

-Here's an example program we can write:
-
-```c
-// hello.c
-#include <stdio.h>
-
-int main() {
-  printf("hello world\n");
-}
-```
-
-It can be compiled as follows:
+You now have a portable program. Please note that your APE binary will
+assimilate itself as a conventional resident of your platform after the
+first run, so it can be fast and efficient for subsequent executions.

 ```sh
-cosmocc -o hello hello.c
-./hello
+./hello.com
+bash -c './hello.com'  # zsh/fish workaround (we upstreamed patches)
 ```

-The Cosmopolitan Libc runtime links some heavyweight troubleshooting
-features by default, which are very useful for developers and admins.
-Here's how you can log system calls:
+So if you intend to copy the binary to Windows or Mac then please do
+that before you run it, not after.
+
+### MacOS
+
+If you're developing on MacOS you can install the GNU compiler
+collection for x86_64-elf via homebrew:

 ```sh
-./hello --strace
+brew install x86_64-elf-gcc
 ```

-Here's how you can get a much more verbose log of function calls:
+Then in the above scripts just replace `gcc` and `objcopy` with
+`x86_64-elf-gcc` and `x86_64-elf-objcopy` to compile your APE binary.
+
+### Windows
+
+If you're developing on Windows then you need to download an
+x86_64-pc-linux-gnu toolchain beforehand. See the [Compiling on
+Windows](https://justine.lol/cosmopolitan/windows-compiling.html)
+tutorial. It's needed because the ELF object format is what makes
+universal binaries possible.
+
+## Source Builds
+
+Cosmopolitan can be compiled from source on any Linux distro. GNU make
+needs to be installed beforehand. This is a freestanding hermetic
+repository that bootstraps using a vendored static gcc9 executable.
+No further dependencies are required.

 ```sh
-./hello --ftrace
-```
-
-You can use the Cosmopolitan's toolchain to build conventional open
-source projects which use autotools. This strategy normally works:
-
-```sh
-export CC=x86_64-unknown-cosmo-cc
-export CXX=x86_64-unknown-cosmo-c++
-./configure --prefix=/opt/cosmos/x86_64
-make -j
-make install
-```
-
-## Cosmopolitan Source Builds
-
-Cosmopolitan can be compiled from source on any of our supported
-platforms. First, you need to download or clone the repository. If
-you're not using x86-64 Linux then you'll need cosmocc too.
-
-```sh
-git clone https://github.com/jart/cosmopolitan cosmo
-cd cosmo
-mkdir -p o/third_party/gcc
-pushd o/third_party/gcc
-wget https://cosmo.zip/pub/cosmocc/cosmocc.zip
-unzip cosmocc.zip
-popd
-```
-
-It's recommended that you install a systemwide APE Loader. This command
-requires `sudo` access to copy the `ape` command to a system folder and
-register with binfmt_misc on Linux, for even more performance.
-
-```sh
-ape/apeinstall.sh
-```
-
-You can now build the mono repo with any modern version of GNU Make. To
-make life easier, we've included one in the cosmocc toolchain, which is
-guaranteed to be compatible and furthermore includes our extensions for
-doing build system sandboxing.
-
-```sh
-o//third_party/gcc/bin/make -j8
+wget https://justine.lol/cosmopolitan/cosmopolitan-1.0.tar.gz
+tar xf cosmopolitan-1.0.tar.gz  # see releases page
+cd cosmopolitan
+make -j16
 o//examples/hello.com
+find o -name \*.com | xargs ls -rShal | less
 ```

-Since the Cosmopolitan repository is very large, you might only want to
-build one particular thing. Here's an example of a target that can be
-compiled relatively quickly, which is a simple POSIX test that only
-depends on core LIBC packages.
-
-```sh
-rm -rf o//libc o//test
-o//third_party/gcc/bin/make o//test/posix/signal_test.com
-o//test/posix/signal_test.com
-```
-
-Sometimes it's desirable to build a subset of targets, without having to
-list out each individual one. For example if you wanted to build and run
-all the unit tests in the `TEST_POSIX` package, you could say:
-
-```sh
-o//third_party/gcc/bin/make o//test/posix
-```
-
-Cosmopolitan provides a variety of build modes. For example, if you want
-really tiny binaries (as small as 12kb in size) then you'd say:
-
-```sh
-o//third_party/gcc/bin/make m=tiny
-```
-
-You can furthermore cut out the bloat of other operating systems, and
-have Cosmopolitan become much more similar to Musl Libc.
-
-```sh
-o//third_party/gcc/bin/make m=tinylinux
-```
-
-For further details, see [//build/config.mk](build/config.mk).
-
-## Debugging
-
-To print a log of system calls to stderr:
-
-```sh
-cosmocc -o hello hello.c
-./hello --strace
-```
-
-To print a log of function calls to stderr:
-
-```sh
-cosmocc -o hello hello.c
-./hello --ftrace
-```
-
-Both strace and ftrace use the unbreakable kprintf() facility, which is
-able to be sent to a file by setting an environment variable.
-
-```sh
-export KPRINTF_LOG=log
-./hello --strace
-```
-
-## GDB
-
-Here's the recommended `~/.gdbinit` config:
-
-```gdb
-set host-charset UTF-8
-set target-charset UTF-8
-set target-wide-charset UTF-8
-set osabi none
-set complaints 0
-set confirm off
-set history save on
-set history filename ~/.gdb_history
-define asm
-  layout asm
-  layout reg
-end
-define src
-  layout src
-  layout reg
-end
-src
-```
-
-You normally run the `.com.dbg` file under gdb. If you need to debug the
-`.com` file itself, then you can load the debug symbols independently as
-
-```sh
-gdb foo.com -ex 'add-symbol-file foo.com.dbg 0x401000'
-```
-
-## Platform Notes
-
-### Shells
-
-If you use zsh and have trouble running APE programs try `sh -c ./prog`
-or simply upgrade to zsh 5.9+ (since we patched it two years ago). The
-same is the case for Python `subprocess`, old versions of fish, etc.
-
-### Linux
-
-Some Linux systems are configured to launch MZ executables under WINE.
-Other distros configure their stock installs so that APE programs will
-print "run-detectors: unable to find an interpreter". For example:
-
-```sh
-jart@ubuntu:~$ wget https://cosmo.zip/pub/cosmos/bin/dash
-jart@ubuntu:~$ chmod +x dash
-jart@ubuntu:~$ ./dash
-run-detectors: unable to find an interpreter for ./dash
-```
-
-You can fix that by registering APE with `binfmt_misc`:
-
-```sh
-sudo wget -O /usr/bin/ape https://cosmo.zip/pub/cosmos/bin/ape-$(uname -m).elf
-sudo sh -c "echo ':APE:M::MZqFpD::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
-sudo sh -c "echo ':APE-jart:M::jartsr::/usr/bin/ape:' >/proc/sys/fs/binfmt_misc/register"
-```
-
-You should be good now. APE will not only work, it'll launch executables
-400µs faster now too. However if things still didn't work out, it's also
-possible to disable `binfmt_misc` as follows:
-
-```sh
-sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/cli'     # remove Ubuntu's MZ interpreter
-sudo sh -c 'echo -1 > /proc/sys/fs/binfmt_misc/status'  # remove ALL binfmt_misc entries
-```
-
-### WSL
-
-It's normally unsafe to use APE in a WSL environment, because it tries
-to run MZ executables as WIN32 binaries within the WSL environment. In
-order to make it safe to use Cosmopolitan software on WSL, run this:
-
-```sh
-sudo sh -c "echo -1 > /proc/sys/fs/binfmt_misc/WSLInterop"
-```

-# LOCAL UNIT TESTS
-#
-# We always run unit tests as part of the normal `make` invocation. you
-# may override the $(TESTARGS) variable to do things such as enable the
-# benchmarking feature. For example:
-#
-#     TESTARGS = -b
-#
-# May be specified in your ~/.cosmo.mk file. You can also use this to
-# enable things like function tracing. For example:
-#
-#     TESTARGS = ----ftrace
-#     .PLEDGE += prot_exec
-#
-# You could then run a command like:
-#
-#     make -j8 o//test/libc/calls/openbsd_test.com.runs
-#
-# You need PROT_EXEC permission since ftrace morphs the binary. It's
-# also worth mentioning that the pledge.com command can simulate what
-# Landlock Make does:
-#
-#     o//tool/build/pledge.com \
-#       -v. -p 'stdio rpath wpath cpath tty prot_exec' \
-#       o//test/libc/calls/openbsd_test.com \
-#       ----ftrace
-#
-# This is useful in the event a test binary should run by itself, but
-# fails to run beneath Landlock Make. It's also useful sometimes to
-# override the verbosity when running tests:
-#
-#     make V=5 TESTARGS=-b o//test/libc/calls/openbsd_test.com.runs
-#
-# This way, if for some reason a test should fail but calls exit(0),
-# then the stdout/stderr output, which would normally be suppressed,
-# will actually be displayed.

+  Normal behavior is non-ELF files with x bit are run by /bin/sh.
+  Linux lets people globally define arbitrary magic interpreters.
+  Your computer couldve been tuned to run MZ scripts inside WINE.
+  So if you use binfmt_misc you need to explicitly register this.

 WORKAROUND

-  ape/apeinstall.sh
-
-NOTES
-
-  If it still doesn't work, possibly due to an overly aggressive WINE
-  or WSL registration, or possibly due to the ordering of definitions,
-  then one troubleshooting step is to just unregister everything using
-  sudo sh -c 'echo -1 >/proc/sys/fs/binfmt_misc/status' and try again.
+  sudo sh -c "echo ':APE:M::MZqFpD::/bin/sh:' >/proc/sys/fs/binfmt_misc/register"
