Build Bitcoin-ABC / Diffs / Bitcoin-ABC Diff Testing passed.

Harbormaster completed remote builds in B5216: Diff 7698.Mar 13 2019, 14:07

Fabien mentioned this in D2658: [CMAKE] Add stack protection flag.Mar 13 2019, 14:52

Fabien mentioned this in D2660: [CMAKE] Define FORTIFY_SOURCE=2.

Fabien mentioned this in D2659: [CMAKE] Add the linker flags to make the relocated sections read only.

Things have been reordered for no apparent good reason. That just makes the review difficult.

66	Why only C++ ?
77	You are testing for this twice.
79	No. You add a dependency to the library the proper way.

This revision now requires changes to proceed.Mar 14 2019, 02:53

66	This is what autotools do, but I agree this is weird. I can include C if you are comfortable with it.

src/CMakeLists.txt
76 ↗	(On Diff #7701)	I see 3 ways of linking against libssp for all the executables: Just adding `-lssp`, which works but is not very elegant Using `link_libraries` but this will eventually add multiple times the `-lssp` due to dependencies Using `target_link_libraries` on a dependency shared by all executables, which is what is done here.
