Hi all.
As prep to eventually building an Openssl instance with support for a specific
hardware engine on linux/64, I'm first building a basic instance.
I start with
source ~/.bashrc
cd /usr/local/src/openssl/openssl-1.0.2a
make clean
unset CFLAGS CPPFLAGS CXXFLAGS
unset SHARED_LDFLAGS LDFLAGS LIBDEPS
unset ZLIB_INCLUDE C_INCLUDE_PATH
./config --openssldir=/usr/local/BUILDTEST --libdir=lib64 \
threads shared enable-ec_nistp_64_gcc_128 no-idea no-ssl2 no-rc5 no-mdc2
This returns
...
Since you've disabled or enabled at least one algorithm, you need to do
the following before building:
make depend
Configured for linux-x86_64.
So I exec
make depend
And that generates a *lot* of this noise about cannot find include file
"stddef.h"
making depend in crypto...

Not that it's authoritative, but Wikipedia suggests
(https://en.wikipedia.org/wiki/Makedepend) that 'makedepend' has
"become superseded by the dependency generation facilities of various
compilers, and is now used primarily as a worst-case fallback, e.g. by depcomp
and GNU Automake"
Also at this bug for an older version of openssl Dr. Stephen Henson had said
"#3566: make depend failes"
https://rt.openssl.org/Ticket/Display.html?id=3566#txn-49052
openssl-1.0.1j
Obviously this needs fixing but as a workaround: if you're
building from scratch (or after "make clean") it should compile fine with
without doing "make depend".
(1) Is the problem with my build because this bug hasn't been fixed yet in
1.0.2a?
(2) Is `makedepend` the problem, and should something else be used?
(3) Is that advice to not exec "make depend" correct, even though the output of
the configure step says specifically to exec it?
Thanks,
Barry
