- $!
- $! 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).
- $!
- $! BC:
- $! Compile byte compiler 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: you appear to have an old version of gas, the GNU assembler.
- GCC 2.x treats external variables differently than GCC 1.x does. Before
- you use GCC 2.x, you should obtain a version of the assembler which works
- with GCC 2.x (gas-1.38 and earlier did not have the necessary support;
- gas-2.0 through gas-2.3 did not work reliably for vax/vms configuration).
- The assembler in gcc-vms-1.42 contained patches to provide the proper
- support, and more recent versions have an up to date version of gas which
- provides the support. gas from binutils-2.5 or later is recommended.
-
- 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.

- -----
- Note: you appear to be missing gas, the GNU assembler. Since

- assembler to make full use of the compiler. It should be put in place
- as GNU_CC:[000000]GCC-AS.EXE.
-
- A prebuilt copy of gas is available from the "gcc-vms" distribution,
- and the gas source code is included in the GNU "binutils" distribution.
- Version 2.5.2 or later is recommended.
