You can now use cosmopolitan.h with an ANSI C89 compiler like MSVC. The Cosmopolitan codebase itself won't support being compiled that way. But you can build objects that link against Cosmopolitan using any compiler and you can furthermore use tools like IntelliSense that can't even GNU See also #40
Cosmopolitan
Cosmopolitan Libc 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 blog post and cosmopolitan libc website. We also have API documentation.
Getting Started
Here's how to get started with the freestanding hermetically-sealed monolithic source repository:
tar xf cosmopolitan-0.1.2.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:
unzip cosmopolitan-amalgamated-0.1.2.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
