------- Comment #5 from gin at mo dot msk dot ru 2006-12-28 13:32 ------- Subject: Re: -B$(build_tooldir)/bin/
It actually broke build of gcc (version 3.0.3) at least on one class of systems, i386-pc-sco3.2v5, as follows. Had on that system gnu binutils installed with PREFIX. Had gcc configured with to install with the same PREFIX. Configured it --without-included-gettext --prefix=PREFIX --with-as=PREFIX/bin/gas --enable-multilib --disable-static --enable-shared (Native `as' was broken in many ways, so GNU one was indeed strongly preferred. OTOH, not specifying `--with-ld', so that native is used `ld', was essential: one from binutils, at least as of 2.11.2, would output elf binaries that system dynamic linker would not link.) make bootstrap would fail as follows. stage1/xgcc -Bstage1/ -BPREFIX/i586-pc-sco3.2v5.0.4/bin/ -DIN_GCC -g -O2 -W -Wall -Wwrite-strings -Wstrict-prototypes -Wmissing-prototypes -Wtraditional -pedantic -Wno-long-long -DHAVE_CONFIG_H -DGENERATOR_FILE -o gengenrtl \ gengenrtl.o ` case "obstack.o" in ?*) echo obstack.o ;; esac ` ` case "alloca.o" in ?*) echo alloca.o ;; esac ` ` case "" in ?*) echo ;; esac ` ` case "" in ?*) echo ;; esac ` ` case "" in ?*) echo ;; esac ` ` case "" in ?*) echo ;; esac ` PREFIX/i586-pc-sco3.2v5.0.4/bin/ld: unrecognized option '-YP,/usr/ccs/lib:/lib:/usr/lib' PREFIX/i586-pc-sco3.2v5.0.4/bin/ld: use the --help option for usage information collect2: ld returned 1 exit status gmake[2]: *** [gengenrtl] Error 1 The `-YP' exists in native `ld', but not in GNU one. That is, gcc correctly configured itself to use to `ld' options for native one. It is exactly `-B$(build_tooldir)/bin/' that expands to `-BPREFIX/i586-pc-sco3.2v5.0.4/bin/' so that gcc finds and invokes GNU `ld' instead of native one. Moving `PREFIX/i586-pc-sco3.2v5.0.4/bin/' directory works around that. If the bug was not already reopened, would do that now. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=28472
