.SH NAME
makeenv - Environment for make(1) via makeenv(1)
.SH SYNPOSIS
.RB .makeenv
.SH DESCRIPTION
The
.B makeenv
file specifies macros, environment variables and
.BR make (1)
options that should be used when the
.BR make (1)
utility is executed via the
.BR makeenv (1)
utility. It can also be used to specify targets
that should also be built.
.PP
The
.B makeenv
file is intepreted line by line, discarding any line
that is empty or otherwise blank or whose first non-blank
character is the hash sign
.RB ( # ).
.PP
Lines starting with a dash
.RB ( - )
as its first non-blank character are interpreted as options
that shall be used, the line is split at each whitespace,
and the empty tokes are discarded and the remaining tokens
put in the command line. Note that it is impossible to have
whitespace in an argument as it will split the argument into
two arguments.
.PP
The remaining lines are parsed as macros if they contain
an equals sign
.RB ( = )
and as targets otherwise. Target lines are separated by
whitespace and each non-empty token is added into the command
line as target. Line that are interpreted as macro lines
have leading and trailing white space removed, and any
sequence of whitespace around it's first equals sign
.RB ( = )
removed.
.SH NOTES
Targets listed in the
.B makeenv
are only guaranteed to be run before targets listed in
the command line if a POSIX conforming implementation
of the
.BR make (1)
utility is used without parallelism turn on.
