ECDSA dropped out of openssl 1.0.0b?

[marcus_of_augustus]

Code:

$ make -f makefile.unix bitcoind
g++ -c -O2 -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DNOPCH -DFOURWAYSSE2 -DUSE_SSL -DUSE_UPNP=0 -o obj/nogui/util.o util.cpp
In file included from util.cpp:4:
headers.h:38:27: error: openssl/ecdsa.h: No such file or directory

Code:

$ openssl version
OpenSSL 1.0.0b-fips 16 Nov 2010

Soooo, no ecdsa.h included with  openssl 1.0.0b.

Do I need to ruin my repository 'adhering' linux just to build bitcoin?

What gives here?

OpenSSL 1.0.0b does have ECDSA. You're using some modified version. A few distros remove ECDSA due to (overblown) patent concerns.

[error]

Don't build bitcoin on a Red Hat derived system. Red Hat strips all the ECC stuff out of OpenSSL.

What if I like Redhat or CentOS?

Bitcoin just cannot be built cleanly on them without a protracted battle with repository nazis or jacking your system (think SElinux scrap)?

Basically, I'm SOOL if I want to build "officially" on anything RH derived is what you are saying, right?

Just install OpenSSL from a tarball (from http://www.openssl.org/source/ ) instead of from the repository. You may also have to link the static libraries libssl.a and libcrypto.a into /usr/lib

Have you actually done this or are you saying "this could be done"?

[theymos]

OpenSSL is an easy compile. You can just prefix it somewhere and use that version for Bitcoin only. I used to do this when my system's OpenSSL was the wrong version.

[error]

Right. The "official" Bitcoin binary builds have OpenSSL statically linked in (or they'd fail spectacularly on a Red Hat box). Just do the same yourself.

[xf2_org]

Fedora / RHEL / derivatives have EC removed for patent related reasons (one reason why I refuse to distribute a bitcoin binary to anyone, for any reason).

It is trivial to compile and install openssl yourself, then build bitcoin.  I run Fedora 14, as do many others on the forums/IRC, and use this solution without a problem.

[marcus_of_augustus]

Messy.

Some instructions for building OpenSSL on CentOS 5.5 for use with Bitcoin are here: http://www.staff.tugraz.at/michael.steurer/Bitcoin-CentOS5.5-V1.pdf

It's pretty straightforward. One small part of the guide is incorrect though. It tells you to run something like this:

Code:

$ ./Configure --prefix=~/Bitcoin/Deps --openssldir=~/Bitcoin/Deps/openssl linux-x86_64

when actually you need this:

Code:

$ ./Configure --prefix=~/Bitcoin/Deps --openssldir=/openssl linux-x86_64

[yogi]

This is also true for 32bit configure.

This:

Code:

$ ./Configure --prefix=~/Bitcoin/Deps --openssldir=~/Bitcoin/Deps/openssl linux-generic32

Needs to be this:

Code:

$ ./Configure --prefix=~/Bitcoin/Deps --openssldir=/openssl linux-generic32

The preferred "fixes" for Red Hat, CentOS, Fedora systems are, if you want to do it yourself,

1) Download SRPM

2) Download associated source code from openssl.org

3) Edit SPECS/openssl.spec,
a) replacing source tarball filename with the downloaded one
b) comment out all references to source1
c) remove the "no-ec" stuff from the configure line

4) rebuild with "rpmbuild -ba SPECS/openssl.spec" or similar

5) install build rpms found in RPMS/

I maintain modified openssl Fedora rpm's for my own use:

Perhaps some other people might find them useful, either outright or just the spec file changes.
