Can't build on Ubuntu 16.04 ARMv71 (scaleway hosting)

Docker image not working same way....

It's not compatible with arm at all -- there are some hacks and/or inline assembly

[Kirya2k]

If you are going to port sourcecode for arm, please do not use arm-specific instructions as you would like to have crosscode for mips/mipscel too. Plz...

It seems that ARMv7 does not have CRC32x assembler directives (possible SSE4 extensions). I have tried to compile using following flags:

+CFLAGS = $(ARCH) -O3 -std=gnu11 -Wall -mtune=cortex-a9 -march=armv7-a -mfpu=vfp -mfloat-abi=softfp -fno-strict-aliasing -fno-strict-overflow -fwrapv -DAES=1 -DCOMMIT=\"${COMMIT}\" -D_GNU_SOURCE=1 -D_FILE_OFFSET_BITS=64

but without success:

/opt/tmp/ccB39ZkK.s:34: Error: selected processor does not support `crc32b (r3),r2' in ARM mode
/opt/tmp/ccB39ZkK.s:52: Error: bad instruction `crc32l (ip),r2'
/opt/tmp/ccB39ZkK.s:73: Error: selected processor does not support `crc32b (r3),r0' in ARM mode
/opt/tmp/ccB39ZkK.s:83: Error: selected processor does not support `crc32b (r2),r0' in ARM mode
/opt/tmp/ccB39ZkK.s:93: Error: selected processor does not support `crc32b (r3),r0' in ARM mode
make: *** [Makefile:89: objs/common/crc32c.o] Error 1

So, the only way is to implement them (CRC32 instuctions) on C by modification of crc32c.c.

A little patch (maybe it even works on MIPS, idk) https://github.com/ICQFan4ever/MTProxyARMPatch

Compiled on ARMv7 successfully

@ICQFan4ever thank you! Just checked - and it works on my Raspberry Pi 3+

Almost a year has passed. : ((

[pokono]

Any plans on porting it?

Thank you! It compiles successfully on my Raspberry pi 4b :D

Can add that the patch works on Raspberry Pi 3 in 2020

[John-Lin]

Compiled failed on ARMv8 on Raspberry Pi 4

I tried to compile for arm ampere for Oracle, it did not work.

Thanks a lot it worked for Orange PI PC. I think it at least works at most of the armhf platforms .
