Re: ImportError: cannot import name md5

[Volker Braun]

Whats the output of "sage -sh ldd local/lib/python/lib-dynload/_hashlib.so"?

It should only depend on glibc, keyutils-libs, libselinux, and krb5-libs, which are quite certainly already installed.

Its probably easiest to compile your own Sage install. Just first install

yum install gcc gcc-gfortran gcc-c++ m4 perl ranlib ImageMagick atlas atlas-devel mercurial openssl-devel

There is a similar problem posted here:

http://ask.sagemath.org/question/1432/code-for-hash-md5-was-not-found-after-fresh-sage

and the solution says to install libssl0.9.8. However, searches for libssl return OpenSSL and I already have OpenSSL and the ancillary devel libraries installed:

OpenSSL 1.0.0j-fips 10 May 2012

Moreover, the only lib I can find on my system that mentions ssl is libssl3.so.

Yep its pretty clear that this can't work. Just compile from source, its easy and fun ;-)

This is the output that you requested:

I tried just linking /usr/lib64/libssl.so.1.0.0j and /usr/lib64/libcrypto.so.1.0.0j to libssl.so.6 and libcrypto.so.6, respectively, but then sage just segfaults. Is it possible that sage does not work with the latest version of OpenSSL?

But I get essentially the same error when I run make:

$ make
cd spkg && \
"../spkg/pipestatus" \
    "env SAGE_PARALLEL_SPKG_BUILD='' ./install all 2>&1" \
    "tee -a ../install.log"
Nothing to (re)build / all up-to-date.

You need to download the source archive. The binary build doesn't include the sources, so there is nothing to (re)build.

[qwerty6789]

Duh. I could have poked around the filetree but was being lazy.

Already downloaded and built from source and it seems to be working so far.

Thanks for your help.
