Andrew, All,
On 2013-11-15 14:28 -0600, Andrew Ruder spake thusly:
> When using ccache TARGET_CC is something like
> ccache gcc
>
> This causes problems in the pv build which attempts to
> override LD because the command ends up being
> make [...] LD=/tools/ccache /tools/gcc LDFLAGS="[...]
>
> As a result, during the build phase it attempts to build
> /tools/gcc which succeeds by doing nothing:
> make[1]: Nothing to be done for `/tools/gcc'.
>
> and during the install phase you get the real build which
> errors out on the LD error this snippet was attempting to
> fix:
> ld -r -o src/library.o src/library/getopt.o \
> src/library/gettext.o
> ld: src/library/gettext.o: Relocations in generic ELF \
> (EM: 40)
> src/library/gettext.o: error adding symbols: File in \
> wrong format
