[fpc-devel] Solaris and binutils 2.22 break fpc linking and workaround

[Helmut Hartl]

Hi,

While building under SmartOS in a buildzone
(IllumOS, former OpenSolaris) i have the problem that with
binutils 2.22 the fpc generated linker script line in ppas.sh

/opt/local/bin/gld -melf_x86_64    -s -L. -o my_program link.res

is not working anymore. Because the only targets the new binutils 2.22 
support on solaris are elf_x86_64_sol2 and elf_i386_sol2.

Manually linking with: (after compiling with -Cn)

$/opt/local/bin/gld -melf_x86_64_sol2 -s -L. -o fpmake_packages link.res

is working!

Others have similar problems on gentoo:

The problem is that on SmartOS the build machines and packages default 
to gcc47 with binutils 2.22.

I "fixed" it for me by compiling the compiler only on Openindiana 151a7
(older binutils) with the following  applied trivial patch, and copying 
the resulting compiler(s) (32/64) bit to the
target system. A full build for a 32 bit and a 64 bit fpc went well.

What are the options to fix this properly ?
I did not manage to get it working with the existing comand line 
options.I think it is needed to influence the -m option which fpc 
generates in "t_sunos", depending on an switch stating the usage of 
binutils greater than
a certain version.
