Re: 64bit initdb failure on macOS 10.11 and 10.12

Hi,

I'm coming back to an old thread. My original issue isn't resolved yet;
this is just to answer your questions below.

I was wrong about that. Everything was 64 bit.

On macOS, everything goes into the same $PREFIX/lib. A library can be
32bit, or 64bit, or both (a "universal binary"). macOS has a tool
named "lipo" that can create those. Usually, you get 64bit-only libraries.
Once I realized this (thanks to Tom Lane), I dropped all configure
arguments related to that.

No, that's not the problem. I only have 64 bit stuff.

On macOS, there's no ldd. The equivalent is "otool -L".
It looks like this (line breaks inserted for readability):

% file /opt/pg/lib/postgresql/ascii_and_mic.so
/opt/pg/lib/postgresql/ascii_and_mic.so: Mach-O 64-bit bundle x86_64

% otool -L /opt/pg/lib/postgresql/ascii_and_mic.so
/opt/pg/lib/postgresql/ascii_and_mic.so:
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 1238.60.2)

BTW, libSystem.B.dylib is a universal binary:

% file /usr/lib/libSystem.B.dylib
/usr/lib/libSystem.B.dylib: Mach-O universal binary with 2 architectures:
[x86_64: Mach-O 64-bit dynamically linked shared library x86_64]
[i386: Mach-O dynamically linked shared library i386]
/usr/lib/libSystem.B.dylib (for architecture x86_64):
Mach-O 64-bit dynamically linked shared library x86_64
/usr/lib/libSystem.B.dylib (for architecture i386):
Mach-O dynamically linked shared library i386

This 32/64 business isn't the problem, though.

I've found out that everything works if I type the configure/make commands
in my shell (which isn't what I said before, sorry about that), but stops
working if I put them into a Perl script (which is how I automate things
across OSes). The weird thing is that the commands are absolutely the same,
and environment is the same, too. Anyway, it seems clear that the error is
on my side. Given enough time, I will find it and report to you.

Thanks, Rainer
