Let me state it more clearly:
The point is that given a precompiled Linux RTL, to my best knowledgeÂ
you can't test any define outside the FPC build environment to see if
the RTL was compiled with FPC_USE_LIBC or not. Maybe there is some
workaround testing for some symbol inside the system unit with{$if
defined(symbol}, but there is no supported global define to test.
Ok, kind of expected that
Targets that enable libc by default (darwin, sunos and openbsd
apparently) by default make this work by locally enabling
FPC_USE_LIBC, usually both in rtl/$target or by other hacks in various
packages/ dirs for shared code, and simply not providing any
alternative in the target specific code.
And to my best knowledge the "LIBC" in the extradefines of Slowaris
(below) means zip, nada, zilch. It is an artifact of 1.0.x times,
which is so old EVEN Lazarus doesn't support it :-)
Ok. ...
Now what I was hoping for, but....
- Darwin isn't a problem. As I test for that anyway.
- I can add {$IFDEF SUNOS} too
- Not sure which others...
Sadly however the list can change. So without "LIBC" or other such
define, this is going to be tricky....
