Eran Tromer 0b928a7b36 README.md: comment about OMP_NUM_THREADS 2015-11-23 18:45:31 +02:00
Madars Virza 40fb45d2dd backtrace is glibc-specific extension, so only use it when available. 
This fixes building libsnark on musl libc-based Linux systems such as
Alpine Linux.
 2015-10-30 20:55:26 -07:00
Eran Tromer 69f312f149 Avoid need for "-lzm" when linking, by including libzm.a into libsnark.a and libsnark.so. 
This means users of libsnark no longer need to remember to add -lzm if and only if libsnark was built with CURVE=B128.

'make install' now installs library files selectively (libsnark.* and maybe supercop.a but not libzm.a).

Eran Tromer 12a6214c05 README: avoid # signs that confuse markdown_py 2015-10-17 16:47:48 +03:00
Eran Tromer 5494e838e5 README.md: add explanations about using libsnark as a library 2015-10-15 04:39:03 +03:00
Eran Tromer 4c6d456652 Makefile: minor cleanup 2015-10-15 04:39:03 +03:00
Eran Tromer a19e4f2ff0 Makefile: build libsnark.a once and then reuse it for libsnark.so and all executables 
This get much cleaner and shorter g++ commands during build, and removes some possibly-buggy dependencies.
 2015-10-15 03:42:04 +03:00
Eran Tromer 3f202f173a Makefile: fix `make install` (issue #15, fixing commit 001b8cbb8d) and other small Makefile fixes. 2015-10-14 02:04:03 +03:00
Eran Tromer 001b8cbb8d Makefile: fix $(LIB_OBJS) in `make install`. This fixed issue #15. 2015-10-13 23:59:04 +03:00
Madars Virza d69bc496e5 Fix a typo in the Makefile. This fixes #14. 2015-10-13 13:16:47 -07:00
Eran Tromer 12c6e21658 Extend profiling code to print parallelism (CPU_time / real_time). 
Also tweak formatting formatting of block entry to drop "[0]} and better align with block exit.
Tested only on Linux, might generate compile or (informative) runtime errors on other platforms.
 2015-10-13 14:09:38 +03:00
Eran Tromer 8a7512af33 Minor addition to profiling output: annotate whole FFTs (including multiplication by coset, etc.) 2015-10-13 14:09:38 +03:00
Eran Tromer 321a3b687d Use *all* cores for batch/multiexponentiation (was capped at 4). 
This speeds up proving by x1.4 to x1.6 on several tested platforms with 6 or 8 cores.

Eran Tromer e2f9fe2949 Makefile fix (*.d cleaning was broken) 2015-10-04 20:26:36 +03:00
Eran Tromer 0c9bd4e205 Makefile fixes 
* Use and clean up .d(ependency) files for executables's objects too.
* Rename OBJS and SRCS to LIB_OBJS and LIB_SRCS to clarify these don't include executables.
* Also, add index to libsnark.a and allow it as a target even if doing a non-static build.
 2015-10-04 04:26:38 +03:00
Eran Tromer 032f8b1858 Makefile fixes 
- Avoid unnecessarily rebuilding executables with unchanged dependencies (bug introduced by commit 998a2373)
- Avoid unnecessarily rebuilding GTest
- Tweak spacing and comments
