Subject: Building shared object file for an SH target
Date: Thu, 19 Mar 2020 15:25:40 +0000	[thread overview]
Message-ID: <VI1PR02MB4256DF8B8377A3340C720BFE96F40@VI1PR02MB4256.eurprd02.prod.outlook.com> (raw)

Hi everyone,

Recently I try to generate shared object files in SuperH-4 using a custom sh-elf-gcc (build options below) but the `-shared` flags seems to have no effect because the linker indicate `cannot find entry symbol start` and the generated file is of type `ELF 32-bit MSB executable, Renesas SH, version 1 (SYSV), statically linked, not stripped`.

I tried to compile 'gcc 9.3.0' and 'binutils 2.34.0' using '--enable-shared':
* ../gcc-9.3.0/configure --prefix=$HOME/opt/sh-elf-2.34-9.3.0 --target=sh3eb-elf --with-multilib-list=m3,m4-nofpu --enable-languages=c,c++ --enable-shared --without-headers --with-newlib --disable-nls --program-prefix=sh-elf-
* ../binutils-2.34/configure --prefix=$HOME/opt/sh-elf-2.34-9.3.0 --target=sh3eb-elf --enable-shared --with-multilib-list=m3,m4-nofpu --disable-nls --program-prefix=sh-elf-

But I have the same result.
I also tried with '--enable-host-shared' and nothing.

How can I do to enable shared file generation with gcc ?

Any insight would be deeply appreciated!

Cheers,
Yann
