Linker Problem: Unrecognized '-Wl,-O1'

Linker Problem: Unrecognized '-Wl,-O1'

Hello,

I am packaging 'arpx' [0] daemon and I have a problem in linking stage.
The linker complains about unrecognized options "-Wl,-O1". It is strange
that i586-poky-linux-ld does not have an option for linker hash table
optimization, which seems to be around for a long time [1]

"-Wl,-O1" is provided by bitbake by default so I think that it is
expected to run but it fails in my configuration. What am I missing
here? I would really appreciate a hand for fixing this.

Hi,

easy to fix edit the buildsystem to usee gcc as linker no ld directly or fix the build system not to use CFLAGS for linking, but LDFLAGS.

Thanks for your suggestion! I have set "LD = ${CC}" in .bb file and it
compiles right now. It seems to work correctly.

There is no problem with the usage of CFLAGS or LDFLAGS but Makefile of
aprx seems to be wrong. All the other packages I have looked so far
utilized autotools and used the compiler for linking. However, aprx
directly sets the linker and it seems to be using autotools as well. I
don't know how the error originated but I guess it's better that I
contact the maintainer and let him know.

### BEGIN: Makefile.in ###

# Compiler and flags
CC=             @CC@
CFLAGS=         @CFLAGS@

# Linker and flags
LD=             @LD@
LDFLAGS=        @LDFLAGS@ $(PROF)

PROGAPRX=   aprx

$(PROGAPRX):    $(OBJSAPRX) VERSION Makefile                            
        $(LD) $(LDFLAGS) -o $@ $(OBJSAPRX) $(LIBS)  

### END: Makefile.in ###
