Currently (revision 64) of libbls checks for lua using pkg-config as both lua5.1 and then also lua using the code below.
opt_pkgs = [('lua5.1', 'lua')]
for pkg, uselib in opt_pkgs:
conf.check_cfg(package = pkg, uselib_store = uselib, args = '--cflags --libs',
mandatory = 'lua' in Options.options.bindings)
When --bindings="lua" is *not* specified this works fine, however, when lua is in Options.options.bindings, it will require that both lua and lua5.1 be found by check_cfg since both are now mandatory, rather than either (as appears to be the case when the lua bindings are not requested). As such on a system with pkg-config lua, the search for lua5.1 will fail and because it is mandatory, the configure phase will fail even though lua is installed. I'm not sure how best to correct this. If you need any further information please let me know...
Hi Mike,
I am not sure I understand this. The code above just checks for the pkg-config package 'lua5.1' and stores its flags in the uselib variables *_lua. It doesn't check for both 'lua5.1' and 'lua'.
If you mean, however, that in some distributions the pkg-config file is lua.pc (instead of lua5.1.pc) then of course I need to find a way to support both of them.
