configure: Remove redundant pkg-config code #1090

real-or-random · 2022-03-16T15:44:10Z

This removes code that detects the pkg-config tool. We used this
back in the days when we had dependencies. ;) It can always be brought
back if we'll need it in the future.

Note that we still deliver a .pc file for this library, and there is
code in Makefile.am to install it. But this does not require the
pkg-config tool; only consumers of the .pc file will need it. This can
be verified by running make install (maybe after mkdir /tmp/pre and
./configure --prefix=/tmp/pre and checking that the .pc file is
installed correctly.

Also note that removal may allow Core to get rid of this hack: https://github.com/bitcoin/bitcoin/blob/d6cb4e8ff0d0772fd549240c21cf08e5213259be/configure.ac#L1939-L1945

…aster 404c530 key: use secp256k1_schnorrsig_sign32 over deprecated secp256k1_schnorrsig_sign (fanquake) ee30bf7 build: remove some no-longer-needed var unexporting from configure (fanquake) 2656629 build: remove --enable-experimental from libsecp256k1 configure (fanquake) d960d4f build: fix MSVC build after subtree update (dhruv) afb7a6f Squashed 'src/secp256k1/' changes from 0559fc6e41..8746600eec (fanquake) Pull request description: The motivation for this bump is some small build cleanups, including [dropping the `--enable-experimental`](bitcoin-core/secp256k1@80cf4ee) flag from the libsecp configure invocation, as well as some [now-redundant](bitcoin-core/secp256k1#1090) `pkg-config` variable exporting from our own configure. We also get the benefit of a slightly more efficient libsecp configure due to bitcoin-core/secp256k1#1088. This also includes a change in our code to migrate from using the [now deprecated](bitcoin-core/secp256k1@99e6568) `secp256k1_schnorrsig_sign` to `secp256k1_schnorrsig_sign32`.

Thanks to elichai2 who noted that the literal '1' is a signed integer, and that shifting a signed 32-bit integer by 31 bits causes an overflow and yields undefined behaviour. While 'scalar_low_impl''s 'secp256k1_scalar_cadd_bit' is only used for testing purposes and currently the 'bit' parameter is only 0 or 1, it is better to avoid undefined behaviour in case the used domain of 'secp256k1_scalar_cadd_bit' expands. 94ae7cbf83 Moved a dereference so the null check will be before the dereferencing 2cb73b1064 scalar_impl.h: fix includes fa33017135 Merge #634: Add a
