- How to compile, link and build GNU Emacs under VMS.
-
-
- A runnable Emacs on VMS consists of two files, an exe file and
- a map file. (It also refers to a DOC file in the [-.etc] sibling directory.
- These files are made automatically and kept straight by Emacs version number.)
-
- For an Emacs being built and tested, these files are `temacs.exe' and
- `temacs.dump' in this directory.
-
- For an installed Emacs, these files are `emacs.exe' and
- `emacs.dump' in the directory above this one. These names are known
- only in the file `emacs.com', also in that directory.
-
- Before you can run Emacs or compile or build any part of Emacs,
- you must run `emacs.com'. It sets up logical names that are used
- by everything else.
-
- Before compiling anything on VMS, you must copy `config.h-dist' to
- `config.h' and make sure it is set up for VMS, using files `m-vax.h'
- and `s-vms4-4.h'. Also copy `vmspaths.h' to `paths.h'.
- `paths.h-dist' is for Unix only. (On VMS versions before 4.4, the
- file names have `_' in place of `-', and you should use `s-vms.h'
- rather than `s-vms4-4.h'.)
-
- Execute `compile.com' to recompile all files that need recompilation.
- Alternatively, execute `precomp.com' to define a command `ccom' that
- can be used to recompile individual files. `ccom' works by executing
- `ccom.com'.
-
- If you compile with optimization, note that in compiler version
- 3.0 there is a bug affecting inline functions. So you must specify
- /OPTIMIZE=NOINLINE when compiling `dispnew.c'. If you still have problems,
- try using /NOOPT.
-
- Compilation will give you lots of warnings about symbols longer than 30
- characters. You must just ignore them. Alternatively, you can
- compile the C program `vms-pp.c' and run all the .c and .h files
- through that program and then compile the results.
- (On VMS versions before 4.4, the program is called `vms_pp.c'.)
-
- **If you use `vms-pp.c', please save the originals .c and .h files
- and distribute them rather than the transformed files
- if you wish to distribute copies of Emacs. Help minimize confusion!**
-
- Execute `link.com' to link the compiled files into `temacs.exe'.
- This process uses `temacs.opt'. You will get lots of linker warnings
- telling you that there were compiler warnings. Just ignore them.
-
- Execute `[-.etc]complink.com' to compile and link the files
- in the [emacs.etc] directory. This must be done before
- `[-.etc]makedoc.com' can be run.
-
- Execute `[-.etc]makedoc.com' to create or update the file `[-.etc]doc.'.
- This must be done if that file does not yet exist or if any of
- the Emacs C sources or preloaded Lisp sources has changed.
- It must be done before `build.com' is run in order to take effect.
-
- Execute `build.com' to run `temacs.exe', initialize it and preload
- some Lisp code, and dump the map file `temacs.dump' containing a copy
- of all the impure storage after initialization.
-
- Execute `testemacs.com' to define the `runtemacs' command
- to run `temacs.exe' with its map file `temacs.dump'.
-
- To install an Emacs, rename `temacs.dump' as `[-]emacs.dump' and
- rename `temacs.exe' as `[-]emacs.exe'.
