[BUG]: Mojo hello world binary size unreasonably large

hoxha-saber commented 1 year ago

Bug description

After building the HelloWorld program, the size of the binary is over 1 MB

-rw-r--r-- 1 1000   36 Sep  7 17:57 hello.mojo
-rwxr-xr-x 1 1000 1.7M Sep  7 17:58 hello

whereas the example from the tutorial shows that it is expected to be quite small (< 30 kb). Is it usually supposed to be this long? Are debugging symbols being included here which makes the binary size a bit larger?

When I run ldd on the binary, I get

        linux-vdso.so.1 (0x00007ffd357e2000)
        libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f9241230000)
        libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f924120d000)
        libtinfo.so.6 => /lib/x86_64-linux-gnu/libtinfo.so.6 (0x00007f92411dd000)
        libstdc++.so.6 => /lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f9240ffb000)
        libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f9240eac000)
        libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f9240e91000)
        libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f9240c9d000)
        /lib64/ld-linux-x86-64.so.2 (0x00007f9241393000)

And the output of nm hello is here.

Output of readelf --all hello is here

Let me know if you need more information. Thanks

Steps to reproduce

Include relevant code snippet or link to code that did not work as expected.
```
fn main():
print("Hello, world!")
```

This is a known problem on some systems. There is an issue on some systems where the linker is not effectively stripping unused runtime symbols from the built binary. We're looking into this at the moment. Thanks for reporting!

stanmueller commented 1 year ago

I have the same problem on Ubuntu 22.4

xtqxk commented 1 year ago

I have the same problem on Ubuntu 22.4

Me too.

DMacMakes commented 1 year ago

Same issue (1.7MB) on Win 10.0.19045 WSL2 Ubuntu 22.04.3 LTS, mojo 0.2.1

ematejska commented 1 year ago

@River707 Are you working on this?

SimplyYummy commented 1 year ago

This looks fixed now with the release of v0.3.0!

The binary size for the simple hello world is now 29K instead of 1.7M for me

jackos commented 1 year ago

Fixed with release 0.3.0 now showing 28kb on Linux

aguspiza commented 11 months ago

hello world with mojo 0.5.1 is now 247KB in ubuntu 20.04 (with python 3.10), 194KB manually stripped (strip --strip-all).

Is there a way to go back to mojo 0.3.0 with latest modular 0.2.2 (95d42445) ?

I'm having the same issue with mojo 0.6.1, I'm working at a docker container:

It seems we are back to some 4Mb:

Hello Team,

Im working on Mac Air M1, i compared the size of the final program in several language and its shocking to see mojo is the largest, you can see the build program of mojo (name : basic)... i'm just worried mojo is larger than the java class file... please fix this... i'm very excited to work with mojo!
