Dear Luarocks developers,
I would like to distribute a few Lua modules for numeric computing
using luarocks, which expose HDF5, OpenCL and MPI to Lua using
LuaJIT's FFI. I started by composing a rockspec for HDF5 for Lua [1].
[1] http://colberg.org/lua-hdf5/
The module is installed using a plugin for GCC that generates matching
FFI C bindings for the installed version of the HDF5 library. Without
a rockspec, a user would install HDF5 for Lua follows:
git clone http://git.colberg.org/gcc-lua
(cd gcc-lua && make)
(cd gcc-lua && make test)
git clone http://git.colberg.org/gcc-lua-cdecl
(cd gcc-lua-cdecl && make test)
git clone http://git.colberg.org/lua-hdf5
(cd lua-hdf5 && make)
(cd lua-hdf5 && make test)
(cd lua-hdf5 && make install PREFIX=/tmp/lua-hdf5_install)
Please find attached the results of a first experiment.
These are the issues I am currently stumbling over:
* How do I pass the path for Lua modules to the Makefile?
If I pass install_variables.PREFIX = "$(PREFIX)" the Lua modules
are installed to the prefix of the rock, but not to the common Lua
modules path that is returned by "luarocks path".
* For a dependency installed as a rock, how do I pass its rock
prefix in build_variables? The build_variables of lua-hdf5
need to point to the rock prefixes of gcc-lua (plugin) and
gcc-lua-cdecl (header file).
* How do I express the dependency on luajit >= 2.0?
* How do I run the test suite of a module before installation?
Thanks,
Peter
