# sci-mathematics/isabelle requires sci-mathematics/sha1-polyml, to avoid
|
|
# this warning:
|
|
# ### load_lib </usr/bin/libsha1.so> : /usr/bin/libsha1.so: cannot open shared
|
|
# object file: No such file or directory
|
|
# ### Using slow ML implementation of SHA1.digest
|
|
# sci-mathematics/sha1-polyml supplies the library libsha1.so. Which
|
|
# is the implementation of SHA1 taken from the GNU coreutils package
|
|
# as described in the sci-mathematics/sha1-polyml README. Isabelle
|
|
# builds libsha1.so in the contrib/polyml/$ML_PLATFORM directory.
|
|
# isabelle dynamically loads libsha1.so as a plugin. The Isabelle-2012
|
|
# linux binary bundle places libsha1.so in the contrib/polyml directory, which
|
|
# is referred to as ML_HOME in the Isabelle Pure/General/sha1_polyml.ML source file.
|
|
# ML_HOME is /usr/bin on Gentoo, and we want isabelle to depend o sha1-polyml.
|
|
# For these reasons isabelle is patched to load it from
|
|
# /usr/$(get_libdir)/sha1-polyml/libsha1.so
