The -ansi and -std=iso9899:199409 somehow confused AIX's standards.h file. I notice that ALL_SOURCE is (re)defined in config.h.

It is the -ansi flag I believe that is doing the harm. Removing that gets the file to compile. Adding that in causes standards.h to not define POSIX_SOURCE and that leads to ulong_t (and other typedefs) not being defined.

AIX version is 6.1 TL07 SP03. GCC is 4.5.2

Hi Perry,

Does this resolve this issue in your env?

Yes it does. Thank you.

I also see your other email and I'll reply to that as well.

I plan to do a build on AIX using the nightly build perhaps once a week to try and correct any build issues early. I need to use something in production and I plan to use 1.9.3 p194 right now. I'm open to suggestions on these matters.

Thank you again,
Perry

avoid compilation error on AIX by -ansi -std=iso9899:199409 (r36038). [ruby-core:46744] [Bug #6791].

This issue is fixed in upper stream as issue #142. (https://github.com/flori/json/issues/142)
