Subject: talitos doesn't build with GCC 4.4.4 (was Re: [PATCH v3 07/17] crypto: talitos - enhanced talitos_desc struct for SEC1)
Date: Sun, 30 Aug 2015 20:25:07 +1000 [thread overview]
Message-ID: <1440930307.907.5.camel@ellerman.id.au> (raw)

Hi guys,
Due to the recent config changes for 85xx, CRYPTO_DEV_TALITOS is now enabled
for corenet64/32_smp_defconfig:
https://git.kernel.org/cgit/linux/kernel/git/scottwood/linux.git/commit/?h=next&id=7e2ad2ef851545c9bd0b5aadc8026c6901a87c50
And so I've started seeing a build failure caused by the patch below (merged as
commit 90490752eb03 ("crypto: talitos - enhanced talitos_desc struct for
SEC1")) but only with GCC 4.4.4.
I assume you're not interested in building with such an old compiler?
The error is:
In file included from drivers/crypto/talitos.c:56:
drivers/crypto/talitos.h:56: error: unknown field 'len' specified in initializer
drivers/crypto/talitos.h:56: warning: missing braces around initializer
drivers/crypto/talitos.h:56: warning: (near initialization for 'zero_entry.<anonymous>')
drivers/crypto/talitos.h:57: error: unknown field 'j_extent' specified in initializer
drivers/crypto/talitos.h:58: error: unknown field 'eptr' specified in initializer

make[3]: *** [drivers/crypto/talitos.o] Error 1
cheers
