¿Dónde pongo CFLAGS en Makefile?

Where do I put CFLAGS in Makefile?

CFLAGS is a variable that is most commonly used to add arguments to the compiler. In this case, it define macros. If you look further down in your makefile, you should see that $(CFLAGS) is probably used like: $(CC) $(CFLAGS) …

CFLAGS should be used in every invocation of the C compiler, both those which do compilation and those which do linking. Every Makefile should define the variable INSTALL , which is the basic command for installing a file into the system.

CFLAGS and CXXFLAGS are either the name of environment variables or of Makefile variables that can be set to specify additional switches to be passed to a compiler in the process of building computer software. If they are not specified in the Makefile, then they will be read from the environment, if present.

What you can do is, have -L/usr/local/lib/ in your makefile as one of the variables. And then you can have -lYARP_OS appended to the LDLIBS. -L is for path to the lib and -l is the lib name here libYARP_OS. a will be passed as -lYARP_OS .

CFLAGS are the name of environment variables or of Makefile variables that can be set to specify additional switches to be passed to a compiler in the process of building computer software.

The default filename for a makefile is Makefile ; this is the name that GNU Make looks for when you run it without any options. The -f argument lets you specify an alternate filename if desired.

The make-specific variables (the ones in capital letters) follow a name convention such that: CC refers to the compiler (gcc in this case); CFLAGS contains compiler directives/options; and LDFLAGS is a list of link (or “load”) directives (here, instructions to link with the C math library).

Makefile contains: dependency rules, macros and suffix(or implicit) rules.

Your general installation procedure will therefore be:

1. Read the README file and other applicable docs.
2. Run xmkmf -a, or the INSTALL or configure script.
3. Check the Makefile .
4. If necessary, run make clean, make Makefiles, make includes, and make depend.
5. Run make.
6. Check file permissions.
7. If necessary, run make install.

Here’s a quick and dirty intro : Files. All you need is a file called “makefile” or “Makefile”. Comments Pound signs (“#”) are comments to end of line. Variables CC = gcc. means that the variable CC contains “gcc”.

Using ldflags with go build. As mentioned before, ldflags stands for linker flags, and is used to pass in flags to the underlying linker in the Go toolchain. This works according to the following syntax: go build -ldflags=”-flag”
