err at cross-compiling

[meAbab]

While I'm doing
$ ./configure --target=arm-linux-gnueabihf --host=arm-linux-gnueabihf
I endup with error

 ----------------------------------------------------
   Unable to find gcrypt.h on this system.
   libgcrypt (libgcrypt11-dev) is required, please install
   and rebuild.
   ----------------------------------------------------

however, libgcrypt is installed, and without target / host errorless configure & make.
How to solve this problem ?

I think you need the armf versions of libgrcypt-dev installed. Note, you need the -dev package installed which includes the headers, not just libgcrypt11.

I usually hand compile libgcrypt & gpg-error and put them in a custom prefix, maybe you can install the armhf versions with x86_64? I've never tried that.

In any case, I really need to refactor this to not use libgcrypt. Hopefully within the next week I'll get some cycles.

[meAbab]

alright, will give a try of armf libgcrypt. Many thanks for your advise!.

Now try after libgcrypt-dev & gpg-error for armf, error comes as -

src/driver/hashlet-command.o: In function `gen_temp_key_from_nonce':

While checking source code, I found sha256_buffer and sha256 is well defined in header.

Tonight, I'll hack up hashlet to not have any libgcrypt dependencies and push a new version. I'll try cross compiling too.

[jbdatko]

Sorry about that... one of those days.

Anyway, I fixed up things on the develop branch. No more libgcrypt dependency!

It's untested, and I probably won't be able to get around to properly testing it until later next week at earliest, but this is how I built it:

Found a bug here:

hashlet/src/cli/hash.c

Lines 35 to 42 in b5a6d2a

	int c;
	int rc = -1;
	/* Perform the hash */
	while ((c = getc (fp)) != EOF)
	{
	rc = sha256_process (&state, (const unsigned char *)&c, sizeof c);
	if (rc) goto OUT;
	}

The type of c is int but only one byte is read for each time, so sizeof c on L40 should be 1.
