I usually pass macro definitions from "make command line" to a "makefile" using the option: -Dname=value. The definition is accessible inside the makefile. I also pass macro definitions from the "makefile" to the "source code" using the similar compiler option: -Dname=value (supported in many compilers).
May 13, 2010 · From command line - make can take variable assignments as part of his command line, mingled with targets: make target FOO=bar. But then all assignments to FOO variable within the makefile will be ignored unless you use the override directive in assignment. (The effect is the same as with -e option for environment variables).
Sep 28, 2016 · If you modify Makefile.in to always define them, then you are making the assumption that your code is only being built on machines where those features are available. If you make that assumption, you should still add checks to configure.ac to confirm it, and have the configure script fail if the dependencies are not met.
Nov 13, 2018 · Just add -Dxxx=yy on the command line (xxx the name of the macro and yy the replacement, or just -Dxxx if there is no value). It's not a Makefile command, it's part of the compiler command line options. It means, xxx is the name and yy is the value. For example,#define xxx (yy) is -Dxxx=yy.
Oct 3, 2009 · @AndersonGreen As I said there's no such thing as a variable declaration in Python. You would create a multidimensional list by taking an empty list and putting other lists inside it or, if the dimensions of the list are known at write-time, you could just write it as a literal like this: my_2x2_list = [[a, b], [c, d]].
Aug 25, 2015 · are ignored by Make. Put simply, make ignores these 2 lines, within the define xx. else foo = 1 Because they are inside a define, and therefore, Make does not evaluate the else as a directive (i.e. as a else part, for ifeq "x" "y"). But, Make clearly parses that endef line (5th line in the ifeq block), as a directive to end the define directive.
48. If by configure release/build, you mean you only need one config per makefile, then it is simply a matter and decoupling CC and CFLAGS: CFLAGS=-DDEBUG. #CFLAGS=-O2 -DNDEBUG. CC=g++ -g3 -gdwarf2 $(CFLAGS) Depending on whether you can use gnu makefile, you can use conditional to make this a bit fancier, and control it from the command line ...
Jul 12, 2011 · 12. You can create an empty two dimensional list by nesting two or more square bracing or third bracket ([], separated by comma) with a square bracing, just like below: Matrix = [[], []] Now suppose you want to append 1 to Matrix[0][0] then you type: Matrix[0].append(1) Now, type Matrix and hit Enter.
Jun 29, 2011 · GNU make 3.81 and 3.82 produce Makefile:10: *** missing separator. Stop. which points to the dep2 call, dep1 is run without errors. The only difference between the two variants is the newlines in dep2 (and the whole point why I'd like to use define).
Dec 12, 2014 · You can use the add_definitions method to pass defines as compiler flags: E.g. somewhere in your projects cmakelists.txt: add_definitions( -DUSE_NEW_CACHE ) CMake will make sure the -D prefix is converted to the right flag for your compiler (/D for msvc and -D for gcc). Alternatively, check out configure_file.
