Hello Folks
This is a follow-up to a previous post about "error:
‘TARGET_ALIAS’ undeclared"....
I think I figured out the problem... there is definitely a bug...
let me explain... there was another similar post on the Internet and their
problem was gcc was including ../bfd/config.h instead of ./config.h when
ran from gas/ . Running the offending command with --save-temps confirms my
problem is the same. When I rename ../bfd/config.h (to avoid conflict)
suddenly 'make' in the gas directory works... so it seems the real problem
is in how #includes are resolved... this also occurred when compiling in
binutils/ again the fix was the same and magically it all worked...
Now I have the luxury of having access to computers with different
compiler versions. With older compilers 4.4.x it works. On newer compilers
( v4.8.3 ) it does not work. So either one of two things are wrong, there
is a new bug in GCC in how it handles include file resolution, or there is
a bug in the binutils source code where the include statements are not
correct and the old version of gcc erroneously did the right thing. Even if
this is a bug in gcc I think it would make binutils more robust if the
correct config.h was specified explicitly. I noticed that this undefined
macro problem pops up a lot and it seems users just give-up before solving
the problem...
Could someone here confirm whether this is a binutils bug or
whether I should post something on the gcc bug tracker... Thanks
If the problem is really in binutils it can be stated simple as
follows: gcc includes the wrong 'config.h' when it is included indirectly
through 'include/alloca-conf.h'. Instead of including the local version of
'config.h' it finds bfd/config.h first. This occurs when running make in
both 'gas/' and 'binutils/'. The problem is avoided in both cases by
temporarily removing 'bfd/config.h'
So let me give some nitty-gritty details to help you understand my
problem in greater detail:
