Building VAX MP

Cross-building x86 version of VAX MP with no network support on x64 Linux systems is possible,

but requires installation of 32-bit version of glibc, with appropriate development header files

(package libcx-dev or glibc-devel, depending on your edition of Linux). For simplicity, we suggest

to build 32-bit version of VAX MP under 32-bit Linux and then copy produced executable file to

64-bit Linux system.

Building VAX MP on OS X

XCode comes with GCC-LLVM compiler. We advise against the use of GCC-LLVM since simulator

produced by it is about 2x less performant than compiled with regular GCC compiler.

Accordingly, VAX MP build files are not even set up for LLVM. Unfortunately OS X or XCode do

not ship with regular GCC included, so to build VAX MP under OS X you need either to obtain

existing prebuilt GCC or build and install GCC on your machine.

VAX MP had been tested under OS X with GCC 4.7.0. We recommend using either this or higher

version of the compiler.

Convert project files from DOS (CR-LF) format to Unix (LF) format by executing the following

commands. The first two commands in the sequence (perl and mv) can be skipped if file

d2u.sh

is intact and are required only if

d2u.sh had been inadvertently converted during project

transfer (such as FTP) to DOS format and fails to run. You can copy these commands from the

comment at the top of

d2u.sh and paste them into Terminal shell prompt.

perl -p -e 's/(\r\n|\n|\r)/\n/g' d2u.sh >d2u.tmp

mv -f d2u.tmp d2u.sh

chmod a+x d2u.sh

./d2u.sh

To build VAX MP, execute in the project’s directory (assuming g++-470 is the name of your

private-built GCC executable):

chmod a+x *.sh

export OSTYPE

CXX=g++-470

export CXX

./mk.sh x64 {dbg|rel} {nonet|shr} [tap] [vde] rebuild

For example:

./mk.sh x64 rel shr tap rebuild

Options meaning is as follows:

x64 selects target processor architecture (32-bit x86 mode is not supported)

dbg|rel selects debug or release build
