While compiling the master branch on my ARM machine, I ran into the
following error. It seems that the Alloc.hs defines functions named
free, malloc, and realloc, which then clash with the built-in
functions of the same name. Any ideas what to do here? Thanks.
You might try adding malloc/realloc/free to the list of symbols in
compiler/cmm/CLabel.hs, math_funs. It looks like your gcc has some
built-in prototypes for these functions that you can't override, which
is messing up the way we generate C code (we assume there are no
prototypes in scope, because we don't #include any headers - this is a
deliberate choice).
