[OpenSIPS-Users] Compiling for arm v7

[Micael]

Hi all,

(Happy New Year!)

I am trying to cross compile 3.2.4 for armv7. Now, I'm new to opensips,
so I have no previous experience to fall back on..

In short: I have issues, getting this warning when compiling
"swp{b} use is deprecated for ARMv6 and ARMv7"


What I have done is:
export 
CC_EXTRA_OPTS="--sysroot=/opt/toolchains/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf/arm-none-linux-gnueabihf/libc
-I /volt001/tmp/sysroots-components/cortexa8hf-neon/openssl/usr/include"


export LD_EXTRA_OPTS="-L 
/volt001/tmp/sysroots-components/cortexa8hf-neon/openssl/usr/lib"

export 
CC="/opt/toolchains/gcc-arm-10.2-2020.11-x86_64-arm-none-linux-gnueabihf/bin/arm-none-linux-gnueabihf-gcc 
-marm -march=armv7-a -mthumb-interwork -mfloat-abi=hard -mfpu=neon"

export CPU=armv7a


I then had to remove the following section in Makefile.defs, otherwise 
it would add strongarm1100 as cpu.

---8<---------8<------
ifeq	($(CC_CLASS), 4.x)
		CFLAGS+=-mcpu=strongarm1100 -ftree-vectorize
else
	#if gcc 3.0+
ifeq	($(CC_CLASS), 3.x)
		CFLAGS+= -mcpu=strongarm1100
else
ifeq	($(CC_CLASS), 2.9x) #older gcc version (2.9[1-5])
$(warning 			Old gcc detected ($(CC_SHORTVER)), use  gcc 3.0.x \
	for better results)

					CFLAGS+=
else
				#really old version
$(warning			You are using an old and unsupported gcc \
					 version ($(CC_SHORTVER)), compile at your own risk!)

endif			# CC_CLASS, 2.9x
endif			# CC_CLASS, 3.x
---8<---------8<------






Once I have done that, everything compiles, but with one and the same 
warning (lots, and lots of them);


e.g.:

Compiling ip_addr.c
/tmp/ccj7cheW.s: Assembler messages:
/tmp/ccj7cheW.s:1857: swp{b} use is deprecated for ARMv6 and ARMv7

/tmp/cc6q8n3v.s:6072: swp{b} use is deprecated for ARMv6 and ARMv7
Compiling md5.c
Compiling md5utils.c


I guess I must not be the only one compiling for arm, so I hope someone 
can point me closer to whats wrong.


Any help appreciated,
