@@ -53,21 +53,6 @@ By default, 32-bit versions of the executables and libraries are installed on
x86-64 machines running Mac OS X 10.5. To build and install 64-bit Mercury on
such a system you must pass the "-m64" option to the C compiler.
Note that if you are building Mercury from scratch using an existing installed
Mercury compiler, i.e. you are not installing using the pre-generated C files in
the source distribution, and you are using a 32-bit Mercury compiler to
bootstrap a 64-bit installation (or vice versa) then you must compile with
--cross-compiling enabled. Not enabling it will result in library installation
aborting with an error message like the following:
Uncaught Mercury exception:
Software Error: pred_table.m: Unexpected: can't locate compare/3
You can enable cross-compilation by putting the following line in a file named
