+Subject: [PATCH] configure: allow cross-compilation
+
+Update configure to allow the user to pass a cross-compiler such as
+--cc=/home/fabrice/buildroot/output/host/bin/riscv64-buildroot-linux-uclibc-gcc
+
+First, use --version instead of -v to avoid a build failure and set
+cc_vendor to gnu if CC compiler contains gcc

May be a problem with the toolchain-wrapper?

The toolchain-wrapper seems to do/try some compile after the '-v'
handling (all output after the 'gcc version 8.3.0 (Buildroot 2020.02)'
line)

A strace of

	$ .../host/bin/arm-linux-gcc -v

shows

	24399 execve(".../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real", ["/home/seiderer/Work/Buildroot/bu"..., "--sysroot", "/.../bu"..., "-mabi=aapcs-linux", "-mfpu=vfp", "-marm", "-mfloat-abi=hard", "-mcpu=arm1176jzf-s", "-Wl,-z,relro", "-v"], 0x7ffca405b940 /* 93 vars */) = 0


This one works:

	$ .../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real --sysroot bla -mabi=aapcs-linux -mfpu=vfp -marm -mfloat-abi=hard -mcpu=arm1176jzf-s  -v

This one fails:

	$ .../host/opt/ext-toolchain/bin/arm-linux-gcc.br_real --sysroot bla -mabi=aapcs-linux -mfpu=vfp -marm -mfloat-abi=hard -mcpu=arm1176jzf-s -Wl,-z,relro -v

Indeed, it seems that -Wl,-z,relro and -v doesn't work, I'll send a
patch to update toolchain-wrapper.c.

[Buildroot] [PATCH 1/1] package/rhash: fix build failure due to gcc -v

[Yann E. MORIN]

Fabrice, All,

On 2020-12-03 21:28 +0100, Fabrice Fontaine spake thusly:
> Fixes:
>  - http://autobuild.buildroot.org/results/8605c16cc28316954ce8b9dcc266974390c5da20

Applied to master with the following changes:

  - retain "$CC -v" as default, fallback to "$CC --version", in the hope
    that it stands better chance with upstream
  - write a commit log to explain the actual root-cause of the build
    failure

Thanks!

Regards,
Yann E. MORIN.

This is only an issue with rhash 1.4.0, and not the older versions we
have on the stable branches, right?

Right, this issue is raised by the configure script which is available
since version 1.3.6.
We're using it since our bump to version 1.4.0 with commit
cdaf43862229fb0f10d2b6b7448bcded2ef8edde.
