           Summary: lib path confusing for vms cross compiler -- dots vs.
                    underscores, and ld vs. wrapper
           Product: gcc
           Version: 4.8.2
            Status: UNCONFIRMED

/usr/local/lib/gcc/alpha-dec-vms/4.8.2/libgcc.a


see the problem -- dots and underscores confused.
The underscores are likely for a VMS host.
So I symlinked the files..then I get:

/usr/local/libexec/gcc/alpha-dec-vms/4_8_2/ld
/usr/local/lib/gcc/alpha-dec-vms/4_8_2/vms-dwarf2eh.o -v
/usr/local/lib/gcc/alpha-dec-vms/4_8_2/crt0.o
/usr/local/lib/gcc/alpha-dec-vms/4_8_2/crtbegin.o

-L/usr/local/lib/gcc/alpha-dec-vms/4_8_2/../../../../alpha-dec-vms/lib

$ link /exe=a_out.exe a_out.opt_tmpfile/opt
sh: $: command not found
collect2: error: ld returned 1 exit status


So this is some host/target confusion.
It should be running the GNU ld that I already have installed, not this
wrapper.

The 4.5.0 was simple, like:
Configured with: /src/gcc-4.5.0/configure -target=alpha64-dec-vms
-build=i686-darwin -disable-werror -enable-target-optspace -disable-nls
-disable-shared -disable-multilib -verbose

I'll go try that again.



I had this all working with 4.5.0 but accidentally deleted part of the
install..

--- Comment #1 from Jay <jay.krell at cornell dot edu> ---
It looks like configure -with-gnu-ld will fix this.
I'm still testing.


It seems to me that you always want -with-gnu-ld here, to trigger    
config.gcc:tmake_file="$tmake_file vms/t-vmsnative", to get you the vms-ld.c
wrapper.


Unless somewhere else gcc knows how to invoke native VMS link.


But I'm building a cross compiler from Darwin here.
So VMS link isn't an option.
Granted, maybe I wrote my own third linker (I didn't).
