That was a recent check-in, and I've been meaning to talk to Todd about it.
If you look at the makefile, line 81, we have
(https://github.com/weidai11/cryptopp/blob/master/GNUmakefile-cross#L81):
HAS_SOLIB_VERSION := 1
Later, that activates the code shown below.
To go back to just the libcryptopp.so, try this:
make -f GNUmakefile-cross ... HAS_SOLIB_VERSION=0
That will force HAS_SOLIB_VERSION low so libcryptopp.so.5.6.3 and
libcryptopp.so.5.6 are *not* created.
I like the patch, but we need to make things easy in the common case
(q.v.). So what I was thinking was (and wanted to talk to Todd about),
should it be "off by default", and make "enabled" the special case? That
is, folks who want it would issue:
make -f GNUmakefile-cross ... HAS_SOLIB_VERSION=1
The common case and avoiding user grief is important to me.
