Call the make command this way: make CFLAGS=-Dvar=42 And be sure to use $(CFLAGS) in your compile command in the Makefile. As @jørgensen mentioned, putting the variable assignment after the make command will override the CFLAGS value already defined in the Makefile.
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 · The whole point of those #defines is to let the configure script define them in config.h, and your source files should #include <config.h>. If you are maintaining the package, you will need to write tests in configure.ac to determine whether or not the system being used has libvncserver installed with jpeg and zlib support. If you modify Makefile.in to always define them, then you are making ...
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]].
Apr 26, 2010 · You can however change the value of a variable on the make command line. If you rewrite your Makefile as follows: ERLCFLAGS += $(ERLCFLAGSADDED) %.erl: %.beam. $(ERLC) $(ERLCFLAGS) -o ebin $<. test: clean compile compile_test. Then, you can invoke make to perform your tests using: make ERLCFLAGSADDED=-DTEST test.
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.
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.
May 17, 2015 · Yes. Most compilers support command line options for specifying #define's. For Visual C++, this is the /D option. In fact, -D was used by some of the earliest C compilers, and remains nearly universally accepted. The only others I can think of that are nearly as close to universal are -c and maybe -O.
