ed5334a Update configure.ac to make it build on OpenBSD (mlmikael)

Pieter Wuille a5a66c70b6 Add support for custom EC-Schnorr-SHA256 signatures 2015-08-03 20:08:51 +02:00
Andrew Poelstra 0739bbb6f0 Add ECDH module which works by hashing the output of ecmult_const 2015-08-01 10:57:33 -05:00
mlmikael ed5334a7fe Update configure.ac to make it build on OpenBSD 
This update is to make libsecp256k1 build on OpenBSD (more specifically OpenBSD 5.7 with Autotools 2.69).

Without the "AM_PROG_CC_C_O" line in configure.ac, ./autogen.sh crashes with "Makefile.am: C objects in subdir but `AM_PROG_CC_C_O' not in `configure.ac'\nautoreconf-2.69: automake failed with exit status: 1".

Pieter Wuille a83bb48068 Make ecmult static precomputation default 2015-07-15 21:41:51 -04:00
Thomas Daede fbecc38a89 Add ability to use a statically generated ecmult context. 
This vastly shrinks the size of the context required for signing on devices with
memory-mapped Flash.

Tables are generated by the new gen_context tool into a header.

c88e2b8 Compile with -O3 by default (Pieter Wuille)
 2014-12-09 11:20:53 +01:00
Cory Fields 1f46b006b7 build: fix __builtin_expect detection for clang 
Using AC_CHECK_DECL, the generated test tries to cast the function to void.
Clang doesn't allow that for builtins.

Gregory Maxwell a099073a7e Enable warnings. 
Wno-unused-function is used for the moment because of the checking
 functions which are currently only used by VERIFY but are not (yet?)
 ifdefed out in normal builds.

Cory Fields 3ab1178d54 build: grab full paths to host tools 
This ensures that make will work even if PATH has changed, which is often the
case when cross-compiling.

Fixes cross-compiled builds when integrated into Bitcoin's repo.
