Hello, the use of readelf was recently introduced via commit 07d66da. The OS X CI build passes quite happily, but I guess that environment may have more tools installed on it than provided by clang/xcode on a "stock" OS X machine.

The command is only needed for gcc, so I suspect limit use of that command to Linux only will "fix" this. Leave it with me, thanks for reporting.

[lovell]

This problem only affects OS X users who already have a globally-installed version of vips, probably via homebrew.

A workaround, assuming you don't need a custom installation of vips, is to remove it via brew remove vips and re-install sharp so it uses own pre-compiled version.

[caoko]

yes

brew uninstall --force vips

npm install ok.

thx.

[lovell]

Thanks for confirming. If it's OK with you I'd like to leave this issue open whilst I fix things for those who wish to use a custom installation of vips on OS X.

readelf command for mac os x.
ref> http://stackoverflow.com/questions/3286675/readelf-like-tool-for-mac-os-x

brew install binutils
sudo ln -s /usr/local/bin/greadelf /usr/local/bin/readelf

but, sharp does not install.

Yeah I am in exactly this situation that would benefit from a fix here -- I want to keep my global install of vips on my development machine for other projects, but am building a small side project that will be deployed on EC2 or etc, so would rather leave it with the local version.

[lovell]

Commit 1a0030e should limit the use of readelf to Linux. Are you able to test?

npm install lovell/sharp

[caoko]

first test env is not installed global vips.
so. i install brew install vips

ok. test commit version 1a0030e. (by chekout)

test env.

@caoko Brilliant, thank you for testing.

The failures from the master branch with vips 8.4.2 are expected and are fixed on the quill branch, which will become sharp v0.17.0 and have a dependency upon vips v8.4.2+.

[lovell]

v0.16.2 out now with this fix, thanks for reporting.
