| $! $ @make-cc1.com [host-compiler] [various] |
| $! |
| $! where [host-compiler] is one of "GNUC", "VAXC", "DECC"; |

| $! "CC1OBJ", "OBJCLIB", "INDEPENDENT", "BC", "ALL", "LINK", "DEBUG". |
| $! "CC1" (C compiler) is the default; of the others, only |
| $! "CC1PLUS" (C++ compiler), "CC1OBJ" (Objective-C compiler), |
| $! and "OBJCLIB" (Objective-C run-time library) are of interest |
| $! for normal installation. |
| $! If both [host-compiler] and other option(s) are specified, |
| $! the host compiler argument must come first. |

| $ |
| $! |
| $! 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). |
| $! |
| $! OBJCLIB: |
| $! Compile Objective-C run-time library. |
| $! |
| $! 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. |
| ----- |

| $goto skip_gas_message |
| $gas_missing_message: |
| $type sys$input: !no version of gas was found |
| |
| ----- |
| Note: you appear to be missing gas, the GNU assembler. Since |
| GCC produces assembly code as output from compilation, you need the |
| 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. |
