------- Comment #5 from aldot at gcc dot gnu dot org 2008-01-19 14:14 -------
Assuming build=i386-linux-*, host==target==sh4-linux-*, i.e. cross-compiling a
native compiler for SuperH:
-) sh*-* forces use_fixproto in config.gcc (why?)
See config.gcc: line 2308
-) stmp-install-fixproto: fixproto
- The comment above this rule is wrong, fixproto is a shell-script.
- this rule doesn't depend on any fix-header, but the stamp is used
to unconditionally install fix-header.
-) build/fix-header${build_exeext}
Tries to compile a binary with mixed build- and host- objects, like
(abbreviated):
$HOSTCC -DGENERATOR_FILE -o build/fix-header \
build/fix-header.o c-incpath.o cppdefault.o build/scan-decls.o prefix.o \
build/scan.o build/errors.o ../libcpp/libcpp.a ../libiberty/libiberty etc.
where build/* is of course incompatible with the other object files.
This suggests that use_fixproto resp. stmp-install-fixproto makes only sense
for
host == build *or* (assuming this is not correct) that we need fix-header for
both build and for host (which is currently not implemented AFAICS).
Please advise.
