Lektor installation fails on MacBookPro OS X 10.6.8

I am trying to install Lektor on a MacbookPro with OS X 10.6.8.

Imagemagick and Python2.7 are already installed.

When I run the installation command:

curl -sf https://www.getlektor.com/install.sh | sh

The build process runs until it gets an error when building '_watchdog_fsevents' extension. The error is:

cc1: error: -Werror=unused-command-line-argument-hard-error-in-future: No option -Wunused-command-line-argument-hard-error-in-future

I've cut and pasted the output just prior to the error into the following code section.

How should I overcome this?

Solution

  • Most likely your version of OS X is too old to support the installation of watchdog with the version of gcc you have. If you cannot upgrade your OS X installation then I recommend installing a recent version of clang via brew and install lektor after exporting CC=clang.

    Note though that Lektor is not tested for OS X < 10.9.
