1744 | clevermous | 1 | # This is not a independent Makefile; it is auxiliary file |
2 | # included from main Makefile. |
||
3 | # It depends on the following variables and macro: |
||
4 | # $(FASM_PROGRAMS) is a list of all programs to build with FASM rule; |
||
5 | # $(binarypart) is a macro which converts from $(1)=item of $(FASM_PROGRAMS) |
||
6 | # to space-escaped full name of binary, $(respace) unescapes spaces; |
||
7 | # $(fbinary) and $(fsource) gives space-unescaped full name of binary |
||
8 | # and source (respectively) of $(f)=item of $(FASM_PROGRAMS). |
||
9 | |||
10 | # Define the rule for all FASM programs. |
||
11 | # Yes, this looks like a black magic. |
||
12 | # But it is not so scary as it seems. |
||
13 | # First, we define "meta-rule" as a rule which is |
||
14 | # macro depending on $(fasmprog). |
||
15 | # Second, the construction foreach+eval creates |
||
16 | # usual rules, one for each $(fasmprog) in $(FASM_PROGRAMS). |
||
17 | # Note that meta-rule is double-expanded, first |
||
18 | # time as the arg of eval - it is the place where $(fasmprog) |
||
19 | # gets expanded - and second time as the rule; |
||
20 | # so all $ which are expected to expand at the second time should be escaped. |
||
21 | # And all $ which are expected to be expanded by the shell should be escaped |
||
22 | # twice, so they become $$$$. |
||
23 | |||
24 | # The arguments of macro fasm_meta_rule: |
||
25 | # $(1) = name of binary file, |
||
26 | # $(2) = name of main source file. |
||
27 | # $(3) = folder of binary file - without spaces. |
||
28 | # $(4) = name of program - without path and extension, |
