Make utility - some Qs togurus..
(Sorry for previous not on enlish! I did not realized it is english forum. )
I am looking for help with Make utility. I could not get help from the 'man' pages.
1. About Macro (as a variable): It is clear about defining any macro in beginning or in command line, but isn't it no way to redefine a macro during a processing?
I would need to setup some indicator variable in a dependency section and make some action in futher processing depend on its value.
Example:
IND1=0
SECT_0: DEP_1
<command>; \
<command>; \
if [ IND1 -eq 1 ]; then <command>; fi

DEP_1:
<command>; \
IND1=1
It comes out that the re-definition IND1 is not heppening. Maybe I should do it differently?

Another related problem that it seems there is no way to change an environment variable from any section. Seems that any section is processed in separate subshell?! Is it true?

So, is there any way to have a some kind of 'variable' in makefile, not just a 'constant' as it looks like with macro?

2. Initialization section: I know, it is .INIT: ..., but how to exit makefile if it would be nessesary or prevent to execute all available section if makefile is ran with no specific section name?

NAME

       install-solaris - install the Solaris operating system

SYNOPSIS

       install-solaris

       install-solaris  invokes  the  Solaris  Install  program. Depending on graphical capability and available memory at the time of invocation,
       install-solaris invokes either a text-based installer or a graphical installer.

       The following minimum requirements for physical memory dictate which features are available during installation:

       For SPARC machines:

       128 MB

           Minimum physical memory for all installation types

       128 MB

           Minimum physical memory required for windowing system

       384 MB

           Minimum physical memory required for graphical-based installation

       For x86 machines:

       256 MB

           Minimum physical memory for all installation types

       256 MB

           Minimum physical memory required for windowing system

       512 MB

           Minimum physical memory required for graphical-based installation

       In some cases, even if the minimum physical memory is present, available virtual memory after system startup can limit the number  of  fea-
       tures available.

       install-solaris  exists  only  on  the Solaris installation media (CD or DVD) and should be invoked only from there. Refer to the  for more
       details.

       install-solaris allows installation of the operating system onto any standalone system. install-solaris loads the software available on the
       installation media. Refer to the  for disk space requirements.

       Refer to the  for more information on the various menus and selections.
