# Cosmopolitan
|
||
|
||
[Cosmopolitan Libc](https://justine.lol/cosmopolitan/index.html) makes C
|
||
a build-once run-anywhere language, like Java, except it doesn't need an
|
||
interpreter or virtual machine. Instead, it reconfigures stock GCC to
|
||
output a POSIX-approved polyglot format that runs natively on Linux +
|
||
Mac + Windows + FreeBSD + OpenBSD + BIOS with the best possible
|
||
performance and the tiniest footprint imaginable.
|
||
|
||
## Background
|
||
|
||
For an introduction to this project, please read the [αcτµαlly pδrταblε
|
||
εxεcµταblε](https://justine.lol/ape.html) blog post and [cosmopolitan
|
||
libc](https://justine.lol/cosmopolitan/index.html) website. We also have
|
||
[API documentation](https://justine.lol/cosmopolitan/documentation.html).
|
||
|
||
## Getting Started
|
||
|
||
Here's how to get started with the freestanding hermetically-sealed
|
||
monolithic source repository:
|
||
|
||
```sh
|
||
tar xf cosmopolitan-0.1.tar.gz # see our releases page
|
||
cd cosmo
|
||
make -j12
|
||
o//examples/hello.com
|
||
```
|
||
|
||
Here's how to get started with the amalgamated binaries, which let you
|
||
bring your own build system:
|
||
|
||
```sh
|
||
unzip cosmopolitan-amalgamated-0.1.zip # see our releases page
|
||
echo 'main() { printf("hello world\n"); }' >hello.c
|
||
gcc -g -O -static -fno-pie -no-pie -mno-red-zone -nostdlib -nostdinc \
|
||
-o hello.com.dbg hello.c -Wl,--gc-sections -Wl,-z,max-page-size=0x1000 -fuse-ld=bfd \
|
||
-Wl,-T,ape.lds -include cosmopolitan.h crt.o ape.o cosmopolitan.a
|
||
objcopy -SO binary hello.com.dbg hello.com
|
||
./hello.com
|
||
```
