|

$! First we figure out what needs to be done. This is sort of like a limited
|
||||
$! make facility - the command line options specify exactly what components
|
||||
$! we want to build. The following options are understood:
|
||||
$!
|
||||
$! LINK: Assume that the object modules for the selected compiler(s)
|
||||
$! have already been compiled, perform link phase only.
|
||||
$!
|
||||
$! CC1: Compile and link "C" compiler.
|
||||
$!
|
||||
$! CC1PLUS:Compile and link "C++" compiler.
|
||||
$!
|
||||
$! CC1OBJ: Compile and link objective C compiler.
|
||||
$!
|
||||
$! ALL: Compile and link all of the CC1 passes.
|
||||
$!
|
||||
$! INDEPENDENT:
|
||||
$! Compile language independent source modules. (On by default).
|
||||
$!
|
||||
$! DEBUG: Link images with /debug.
|
||||
$!
|
||||
$! If you want to list more than one option, you should use a spaces to
|
||||
$! separate them.
|
||||
$!
|
||||
$! Any one of the above options can be prefaced with a "NO". For example,
|
||||
$! if you had already built GCC, and you wanted to build G++, you could use the
|
||||
$! "CC1PLUS NOINDEPENDENT" options, which would only compile the C++ language
|
||||
$! specific source files, and then link the C++ compiler.
|
||||
$!
|
||||
$! If you do not specify which compiler you want to build, it is assumed that
|
||||
$! you want to build GNU-C ("CC1").
|
||||
$!
|
||||
$! Now figure out what we have been requested to do.

Note: GCC 2.0 treats external variables differently than GCC 1.40 does.
|
||||
Before you use GCC 2.0, you should obtain a version of the assembler which
|
||||
contains the patches to work with GCC 2.0 (GCC-AS 1.38 does not contain
|
||||
these patches - whatever comes after this probably will). The assembler
|
||||
in gcc-vms-1.40.tar.Z from prep does contain the proper patches.
|
||||
|
||||
If you do not update the assembler, the compiler will still work,
|
||||
but `extern const' variables will be treated as `extern'. This will result
|
||||
in linker warning messages about mismatched psect attributes, and these
|
||||
variables will be placed in read/write storage.
