graphite2: fatal error: 'unistd.h' file not found

[jam@…]

After an hour or two xfce fails to build.

The error is <unistd.h> not found

but find /Application/Xcode.app gives

Frustration is!! I re-installed the command line tools. I see no changes. I could not have got this far without CLI tools! But it is now compiling and has been doing so for the last two hours. The log is posted! the explanation is beyond me. Sorry for the noise!

In the future, please use WikiFormatting, fill in the Port field with the port that actually fails to build and Cc the port maintainers (port info --maintainers graphite2), if any.

I can't reproduce this problem on my El Capitan system. Check if /usr/include/unistd.h exists. If it does not, then you haven't successfully installed the command line developer tools.

Building graphite2 takes under a minute, not hours.

[jam@…]

The compile times listed are on an old (2 core) mac mini and for the whole build of xfce. The log is proof that the fail occured but after re-downloading CLI tools for xcode everything worked for me too. Hence my frustrated lament above

[ryandesign (Ryan Carsten Schmidt)]

Ok, if reinstalling the command line tools allowed graphite2 to build, then there's nothing for us to do.
