It is invoked in the following manner: Program $env <program name>, <source or object files>; The program name will have the value of the C<SUFEXE> construction variable appended (by default, C<.exe> on Win32 systems, nothing on Unix systems) if the suffix is not already present. Source files may be specified in place of objects files-,-the C<Objects> method will be invoked to arrange the conversion of all the files into object files, and hence all the observations about the C<Objects> method, above, apply to this method also. The actual linking of the program will be handled by an external command which results from expanding the C<LINKCOM> construction variable, with C<%E<lt>> set to the object files to be linked (in the order presented), and C<%E<gt>> set to the target. (See the section above on construction variable expansion for details.) The user may set additional variables in the construction environment, including C<LINK>, to define which program to use for linking, C<LIBPATH>, a colon-separated list of library search paths, for use with library specifications of the form I<-llib>, and C<LIBS>, specifying the list of libraries to link against (in either I<-llib> form or just as pathnames. Relative pathnames in both C<LIBPATH> and C<LIBS> are interpreted relative to the directory in which the associated construction environment is created (absolute and top-relative names may also be used). Cons automatically sets up dependencies on any libraries mentioned in C<LIBS>: those libraries will be built before the command is linked. --> <para> X </para> <section> <title>The &Program; Builder</title> <para> X </para> </section> </section>
