Hi, tcc port on Apple M1 is not too bad as long as you accept it generates code 
for x86_64 which is then translated by rosetta.

That said, your problem is that tcc does not define __LITTLE_ENDIAN__ as gcc 
does

jullien@mobley:~ $ tcc -dM -E - < /dev/null | grep END | sort
#define __BYTE_ORDER__ __ORDER_LITTLE_ENDIAN__
#define __ORDER_BIG_ENDIAN__ 4321
#define __ORDER_LITTLE_ENDIAN__ 1234

jullien@mobley:~ $ gcc -dM -E - < /dev/null | grep END | sort
#define __BYTE_ORDER__ __ORDER_LITTLE_ENDIAN__
#define __LITTLE_ENDIAN__ 1
#define __ORDER_BIG_ENDIAN__ 4321
#define __ORDER_LITTLE_ENDIAN__ 1234
#define __ORDER_PDP_ENDIAN__ 3412

You can see that __LITTLE_ENDIAN__ is missing for tcc

I've just added this missing definition on mod, you can test it right now.

C.

Hi, the M1 chip is an ARM64 processor, not a x86_64 one.

Perhaps the ARM support of TCC is not up to par with its x86 counterpart.

Good luck anyway.

Objet: [Tinycc-devel] Compile Libbtc for Apple M1 with tcc

Hello,

Trying to compile Libbtc for Apple M1 with tcc. It worked with an Apple
Intel machine and setting CC=tcc. Since tcc can build it on the Intel with
macOS I try ask here if you might know the cause of the failure. With the
Apple M1 the following message comes from make

In file included from ./include/btc/serialize.h:34:
In file included from ./include/btc/portable_endian.h:22:
/Library/Developer/CommandLineTools/SDKs/MacOSX.sdk/usr/include/libkern/OSByteOrder.h:314:
error: #error Unknown endianess.
