RE: Almost successfull compiling GCJ, however..

[Me Myself and I <stargate7thsymbol@live.co.uk>]

The directory that I refer to as the build directory is
my objdir/ subdirectory, outside the source code directory.

I successfully run configure within the objdir/ directory.

However make; does not complete (inside the objdir directory)
because of the error I keep on getting,

-----------------------------------------------------------------------------------------------------------------------
fib2_ui.c:76:29: error: 'FIB_TABLE_LIMIT' undeclared (first use in this function)
fib2_ui.c:76:29: note: each undeclared identifier is reported only once for each function it appears in
make[5] *** [fib2_ui.lo] Error 1
make[5] Leaving directory '/home/User/gcc-4.6.2/objdir/gmp/mpn'
make[4] ***all-recursive] Error 1

make[1] *** [stage1-bubble] Error 2
make[1] Leaving directory '/home/User/gcc-4.6.2/objdir'
make: *** [all] Error 2
-----------------------------------------------------------------------------------------------------------------------

there is indeed an instance inside my objdir/ directory,

.../objdir/gmp/gen-fib.exe

(compiling on a windows/unix esque platform)

however I still always get the errors stipulated inside my included dashed lines.

Inspiration, anyone?
