Failed to build on Mac OS 10.7.5

[cadencemarseille]

I am trying to build Rust @424c171 on Mac OS 10.7.5, but I am encountering the error:

make[1]: Nothing to be done for `all'.
link: x86_64-apple-darwin/rt/stage0/librustrt.dylib
i686-apple-darwin11-llvm-g++-4.2: x86_64-apple-darwin/rt/libuv/libuv.a: No such file or directory
make: *** [x86_64-apple-darwin/rt/stage0/librustrt.dylib] Error 1

./configure reports the submodule status as:

configure: git: submodule status
 f407f09c94e00d2d570e8e42114e3f6848b2deb2 src/gyp (f407f09)
 d88cf5652a1afb23939da0bae86c70ec521b9921 src/libuv (v0.11.7-60-gd88cf56)
 c9ffab392a39eb85f2f15ffc8d41e8c4f4397b8e src/llvm (remotes/origin/rust-llvm-2013-09-15)

When I cd into x86_64-apple-darwin/rt/libuv/ and make, I see:

make: Nothing to be done for `all'.

There was another issue reporting the same error message (#9625), but I am not passing a -j option to make. I am simply running:

./configure --prefix=/Users/cadencemarseille/.local
make

Looking in x86_64-apple-darwin/rt/libuv/Makefile, it looks like there are supposed to be Debug and .deps folders within x86_64-apple-darwin/rt/libuv/, but these have not been created. Creating them myself (via mkdir) does not fix the issue.

When we've seen this beforehand it's normally a problem with gyp generating libuv's makefile, which is in turn often associated with missing xcode (or only have the command line tools), could you take a look specifically around where the makefile is generated for libuv and see if you can find some gyp-specific errors?

I do not see much regarding libuv in the configure output:

...

Can you remove $target/rt/libuv/Makefile ? That's the file which we need to generate, and then when that file is re-generated an error often crops up (but gyp doesn't propagate the error for some reason). You should be able to get the output with:

rm $target/rt/libuv/Makefile
make `pwd`/$target/rt/libuv/Makefile

Hi Alex. This got me past the error. Thank you for your help!

I had the same issue. It turns out I needed to run sudo xcode-select -switch /
