homebrew-musl-cross's Introduction

homebrew-musl-cross

One-click static-friendly musl-based GCC macOS-to-Linux cross-compilers based on richfelker/musl-cross-make.

brew install filosottile/musl-cross/musl-cross

By default it will install full cross compiler toolchains targeting musl Linux amd64 and arm64.

You can then use x86_64-linux-musl- or aarch64-linux-musl- versions of the tools to build for the target. For example x86_64-linux-musl-cc will compile C code to run on musl Linux amd64.

The "musl" part of the target is important: the binaries will ONLY run on a musl-based system, like Alpine. However, if you build them as static binaries by passing -static as an LDFLAG they will run anywhere. Musl is specifically engineered to support static binaries.

To use this as a Go cross-compiler for cgo, use CC, GOOS/GOARCH, CGO_ENABLED, and -extldflags.

CC=x86_64-linux-musl-gcc CGO_ENABLED=1 GOOS=linux GOARCH=amd64 \
    go build -trimpath -ldflags "-extldflags -static"

To use this with Rust, add an entry to .cargo/config and use the corresponding target.

[target.x86_64-unknown-linux-musl]
linker = "x86_64-linux-musl-gcc"

Other architectures are supported. For example you can build a Raspberry Pi cross-compiler:

brew install filosottile/musl-cross/musl-cross --build-from-source \
    --without-x86_64 --without-aarch64 --with-arm-hf

(Note: a custom build takes around ten minutes per architecture on an M2. The installed size is between 150MB and 300MB per architecture.)

If you encounter issues with a missing musl-gcc binary, the build system might be assuming the presence of the musl host compiler wrapper. That should be reported as an issue, but you might be able to workaround it by creating a symlink:

ln -s "$(brew --prefix musl-cross)/bin/x86_64-linux-musl-gcc" /usr/local/bin/musl-gcc

Update GCC version

I tried to use this to build my project, but I use some C++20 features including the new comparison (<=>) operator, which GCC 9 doesn’t support. So I got a “no such file” error on #include <compare>.

GCC 10 does build my project successfully on Linux. I’m just trying to find a way to do this build on macOS. So it would be nice if you updated to a newer version of GCC.

[Error] brew install filosottile/musl-cross/musl-cross --without-x86_64 --with-mips

Provide symlink for `musl-gcc`?

Many scripts expect the command musl-gcc to exist. Making a symlink in my $PATH from musl-gcc to $(which x86_64-linux-musl-gcc) caused scripts that have this expectation to work. Seems like it'd be useful to provide this by default?

Error: Failed to download resource "musl-cross"

I first noticed this from github-actions: https://github.com/joemiller/vault-token-helper/runs/2313692421?check_suite_focus=true

And was able to reproduce locally (macOS 10.15.7 catalina, intel):

$ brew install FiloSottile/musl-cross/musl-cross

Maybe there is no bottle for macOS Catalina? Or maybe an issue from the move to B2 ?

BTW, thank you so much for building and maintaining this tap!!!!

Apple silicon support?

It seems that there are some build errors on Apple M1 hardware:

isl.gforge.inria.fr down for days

Hi,
Since some days I am trying to install musl-cross, but brew returns the following error:
==> Downloading http://isl.gforge.inria.fr/isl-0.21.tar.bz2 -=O=- # # # # curl: (7) Failed to connect to isl.gforge.inria.fr port 80: Operation timed out Error: Failed to download resource "musl-cross--isl-0.21.tar.bz2" Download failed: http://isl.gforge.inria.fr/isl-0.21.tar.bz2
Googling around it seems that isl.gforge.infria.fr is down for days. Here a discussion in a Google group https://groups.google.com/g/isl-development/c/JGaMo2VUu_8.
I was wondering if you could update the formula to retrieve the resource from a mirror site.
Thank you!

Add support for powerpc-linux-musl

Do you think you will be able to add support for powerpc-linux-musl?

Allow x86_64 with others

If I run brew install FiloSottile/musl-cross/musl-cross --with-aarch64 --with-x86_64, it will not build the x86_64 chain, so I had to change /opt/homebrew/Library/Taps/filosottile/homebrew-musl-cross/musl-cross.rb:

-  option "without-x86_64", "Do not build cross-compilers targeting x86_64-linux-musl"
+  option "with-x86_64", "Build cross-compilers targeting x86_64-linux-musl"

PS. Thanks for this repo, it saved me a lot of time!

Add note on expected install time

Hi @FiloSottile!

Thanks for maintaining this project 🙇‍♀. I got here by trying to install a rust runtime for AWS Lambda from this blog post.

I ran:

brew install filosottile/musl-cross/musl-cross

And it took maybe 30 minutes? I was confused and canceled and retried multiple time, thinking the process got stuck.

When I saw this in the readme:

(It takes a while, getting a cup of coffee won't do.)

I figure now this kind of install time is expected.

My request:

Make the note in the Readme a bit clearer - can you suggest a ballpark of expected normal time?
Is it possible to add a warning about the install time to the brew output?

Happy to submit a PR if you have pointers on this two questions! thanks!

curl: (60) SSL certificate problem: Invalid certificate chain
More details here: https://curl.haxx.se/docs/sslcerts.html

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

What I miss? How to install homebrew-musl-cross?

Bottled version doesn't work because of libisl

Running the bottled version, I get:

dyld: Library not loaded: @@HOMEBREW_PREFIX@@/opt/isl/lib/libisl.15.dylib
  Referenced from: /usr/local/Cellar/musl-cross/0.9.7/libexec/bin/../libexec/gcc/x86_64-linux-musl/6.3.0/cc1

It looks like cc1 has a dependency on libisl:

otool -L ../libexec/libexec/gcc/x86_64-linux-musl/6.3.0/cc1
../libexec/libexec/gcc/x86_64-linux-musl/6.3.0/cc1:

	/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current version 1252.0.0)

libisl wasn't installed automatically because its not declared as a dependency. Also, Hombrew now has libisl.19, not .15, so it doesn't work even if I try to install it.

error occurred: Failed to find tool. Is `musl-g++` installed?

Can not run on debian/Ubuntu

executable that build with the follow command can run on alpine(which is inside my docker container)

env CC=x86_64-linux-musl-gcc CGO_ENABLED=1 GOOS=linux GOARCH=amd64 go build -ldflags "-w -s" -o "Hello2-Linux"

but can not run on Debian/Ubuntu, it returns error:

bash: ./Hello2-Linux: No such file or directory

So how can I build executables that can run on debian/Ubuntu etc.

[undefined reference] while compiling on Apple Silicon

Hi @FiloSottile, many thanks for maintaining this repo offering macOS-to-Linux cross-compiling solutions for Go, you just can't imagine how you make my life easier when one of my projects needs to embed Rocksdb, such an awesome key-value storage that I've recently developed a love-hate relationship with.

Utilizing the c and c++ cross compiler, my first try on the go build command is as follows:

CGO_LDFLAGS="-L/opt/homebrew/Cellar/[email protected]/7.7.3/lib -L/opt/homebrew/Cellar/zstd/1.5.5/lib -L/opt/homebrew/Cellar/lz4/1.9.4/lib -L/opt/homebrew/Cellar/snappy/1.1.10/lib -L/opt/homebrew/Cellar/zlib/1.2.13/lib -L/opt/homebrew/cellar/musl-cross/0.9.9_1/libexec/lib" CGO_CFLAGS="-I/opt/homebrew/cellar/[email protected]/7.7.3/include" CGO_ENABLED=1 GOOS=linux  GOARCH=amd64 CC=x86_64-linux-musl-gcc CXX=x86_64-linux-musl-g++ go build -o yeeeeeeeeet

Ideally, this should work, but my terminal once again yells at me

-link-2821846975/000054.o: in function `gorocksdb_comparator_with_ts_create':
grocksdb.c:(.text+0x88): undefined reference to `rocksdb_comparator_with_ts_create'

collect2: error: ld returned 1 exit status

Being spammed of those countless undefined reference errors, I think there must have been something wrong with my go build configurations, by looking and half-guessing at https://stackoverflow.com/questions/62158905/undefined-references-to-symbols-in-standard-libraries-with-musl-cross-make , I changed my go build command as follows:

CGO_LDFLAGS="-L/opt/homebrew/Cellar/[email protected]/7.7.3/lib -L/opt/homebrew/Cellar/zstd/1.5.5/lib -L/opt/homebrew/Cellar/lz4/1.9.4/lib -L/opt/homebrew/Cellar/snappy/1.1.10/lib -L/opt/homebrew/Cellar/zlib/1.2.13/lib -L/opt/homebrew/cellar/musl-cross/0.9.9_1/libexec/lib" CGO_CFLAGS="-I/opt/homebrew/cellar/[email protected]/7.7.3/include" CGO_ENABLED=1 GOOS=linux  GOARCH=amd64 CC=x86_64-linux-musl-gcc CXX=x86_64-linux-musl-g++ go build -o yeeeeeeeeet

Yet the same error occurs.

I think there must have been something extremely simple and outright on the surface, right below my nose, that somehow I've just managed to unsee, yet I can't figure out what and how. Partly because my familiarity with C is not competent enough. And that's why I'm now humbly asking for any assistance that can help me get this over with.

GCC can’t find <linux/futex.h>

I’m getting a build error “no such file” on #include <linux/futex.h>, down inside a library I use. And when I found the system headers down inside /opt/homebrew/Cellar/musl-cross/0.9.9_1, they don’t include such a header or even a linux subdirectory.

I know very little about Linux development, but I’m guessing this may have to do with musl vs. the default Linux library? In any case I have no idea how to work around this; it’s not even my code including this header, rather a 3rd party library.

Compiling Staticaly linked OpenSSL for linux-x86_64

Any one succeeded to make this usable at all?
I tried every option I can think of but it's not linking statically like with GregorR/musl-cross in ubuntu

CC="/usr/local/bin/x86_64-linux-musl-gcc -static" LD="/usr/local/bin/x86_64-linux-musl-ld -static" \

no-async no-zlib no-zlib-dynamic linux-x86_64

/usr/local/bin/gmake

I get loads of :(.text+0x21c): undefined reference to at linking stage

Document disk space requirements

I'm currently installing this and it's so far taken up about 4 gigabytes of disk space, and climbing. I think it would be nice to document along with the installation time how much disk space it's expected to take up while building.

how to install with --with-mipsle

My target is little endian.Thank you!

Use a newer gcc or clang

Would be possible to use a gcc-8 or a recent clang?

Linkage issues with cross-compiling OpenSSL

I'm trying to cross-compile OpenSSL and it wanted linux/mmap.h. So I symlinked /usr/local/Cellar/musl-cross/0.9.9/libexec/x86_64-linux-musl/include/sys to /usr/local/Cellar/musl-cross/0.9.9/libexec/x86_64-linux-musl/include/linux and it worked - up until OpenSSL wanted linux/version.h.

So I went over to Ubuntu's linux-libc-dev-amd64-cross package and extracted that into /usr/local/Cellar/musl-cross/0.9.9/libexec/x86_64-linux-musl/. Then everything broke but that's because I forgot to remove the symlink.

So after removing the symlink, everything built successfully, but at the linking step, this happened:

Do you know what this means? Or how to fix it?
