Building native gem extension nio4r fails on mac OS High Sierra due to integer precision / division by zero #178

msc01 · 2017-12-26T15:32:46Z

I'm trying to install the current Rails version on my Mac running High Sierra v10.13.2 but whatever I try, it always fails while building the native gem extensions nio4r.

I'm sure there's something wrong with my system / environment but I can't get my head around the error messages as I'm not really a C developer.

I'm on Ruby 2.4.3 but tried several other versions like 2.5.0, 2.4.0., 2.3.0 via RVM as well. I've found a lot on StackOverflow, etc. around this like missing developer tools and so on, but nothing seems to apply to my situation. Depending on the Ruby version it either fails with integer precision with Ruby 2.4.x or with a division by zero with Ruby 2.5.0.

Here's the error message for Ruby 2.4.3:

ERROR:  Error installing rails:

Hi there,

The issues you pointed out regarding casts to different integer sizes are just warnings. They are not the actual culprit. The actual culprit is this (and a few other things):

/usr/local/include/port.h:32:8: error: unknown type name 'bool'
extern bool pg_set_noblock(pgsocket sock);

Something (certainly looks like Postgres) installed a port.h header in /usr/local/include which extconf.rb is misidentifying as the header for Solaris I/O completion ports. It also appears to be using C features (e.g. C99) which the compiler isn't configured to support.

I think (temporarily) removing the file should resolve the issue. extconf.rb could be updated to look for e.g. PORT_SOURCE_FD in port.h rather than assuming any old port.h means we're on Solaris.

Hi Tony,

Thanks for replying so quickly to my issue on Christmas!

There was indeed an old port.h file from an abandoned Postgres installation. Removing it solved my issue and nio4r could be built successfully.

Merry Christmas!

Cheers,
Michael

"port.h" is a pretty generic name, and apparently has caused nio4r to fail to build in practice. Before trying to use it, make sure it contains the types we expect (for Solaris I/O completion ports)
