Gentoo gcc 4.3.4 - Linking ascii objects #35

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
gcc version 4.3.4 (Gentoo 4.3.4 p1.0, pie-10.1.5)
Linking of ascii text files (cgi_root.html->cgi_root.o, etc.) seems to be a 
problem in my 
environment

What is the expected output? What do you see instead?

I don't think that ASCII or the fact that you are using Gentoo is the problem 
here. 
More likely, the problem is that you are the first reported user to build on a 
powerpc. You will need to edit Makefile.am and add the missing information to 
the 
definition of "objcopyflags".

Unfortunately, without having easy access to a powerpc machine with Linux on 
it, I am 
not quite sure what needs to be entered here.

Try running "objcopy" without any arguments, and it should tell you which build 
targets it supports. This should help you get started.

Once you have a solution, please let me know and I'll add it to the official 
source 
tree.

Seems to work - I'm not sure about the -B because it has no impact at all on 
the ppc platform but it looks much better 
;-) Thanks a lot and have a good sleep

objcopyflags = case "$(host_cpu)" in                                  \
                         i[0-9]86) echo '-O elf32-i386 -B i386';;             \
                         x86_64)   echo '-O elf64-x86-64 -B i386:x86-64';;    \
                         arm*)     echo '-O elf32-littlearm -B arm';;         \
                         powerpc*) echo '-O elf32-powerpc -B powerpc';;       \

Please let me know, if you have any problems with it.
