One solution is to set the CFLAGS environment variable to the define macro:
$ export CFLAGS="$CFLAGS -DUSE_LONGLONG" # or whatever command your shell uses to set and export environment variables
then just type the previous commands as normal:
$ ./configure
$ make
$ make install
If your make file was written to use the CFLAGS environment variable, you will see the -DUSE_LONGLONG argument on the command line each time make invokes gcc.

Hi Everyone,
I can ask what is the option to compile a 64 bits program using gcc. I have looked everywhere but can't find it. Before I used to use cc and the -q64 flag was the option to generate the 64 bits binary. Can anyone tell me what is the flags when using gcc. Thanks...... (3 Replies)

I'm currently trying to make a fresh build from scratch/source of FFMPEG.
This said, it brings quite a tail with it, so the use of a script was very obvious.
Anyway, i'm currently stuck at named package.
Lets ignore the tarball/download line, as the error is after.

MKDEP(1) BSD General Commands Manual MKDEP(1)
NAME
mkdep -- construct Makefile dependency list
SYNOPSIS
mkdep [-ap] [-f file] [flags] file ...
DESCRIPTION
The mkdep utility takes a set of flags for the C compiler and a list of C source files as arguments and constructs a set of include file
dependencies which are written into the file ``.depend''. An example of its use in a Makefile might be:
CFLAGS= -O -I../include
SRCS= file1.c file2.c
depend:
mkdep ${CFLAGS} ${SRCS}
where the macro SRCS is the list of C source files and the macro CFLAGS is the list of flags for the C compiler.
The user has the ability to change the preprocessor and preprocessor options used. For instance, to use gcc as the preprocessor and to
ignore system headers, one would use
depend:
env MKDEP_CPP="gcc -E" MKDEP_CPP_OPTS=-MM mkdep
${CFLAGS} ${SRCS}
The options are as follows:
-a Append to the output file, so that multiple mkdep's may be run from a single Makefile.
-f Write the include file dependencies to file, instead of the default ``.depend''.
-p Cause mkdep to produce dependencies of the form:
program: program.c
so that subsequent makes will produce program directly from its C module rather than using an intermediate .o module. This is useful
for programs whose source is contained in a single module.
ENVIRONMENT
CC Specifies the C compiler to use. The specified compiler is expected to have options consistent with the GNU C compiler.
MKDEP_CPP Specifies the preprocessor to use. The default is "${CC} -E".
MKDEP_CPP_OPTS Specifies the non-CFLAGS options for the preprocessor. The default is "-M".
FILES
.depend File containing list of dependencies.
SEE ALSO
cc(1), cpp(1), make(1)
HISTORY
The mkdep command appeared in 4.3BSD-Tahoe.
