dnl @synopsis AX_DMD
|
|
dnl
|
|
dnl Test for the presence of a DMD-compatible D2 compiler, and (optionally)
|
|
dnl specified modules on the import path.
|
|
dnl
|
|
dnl If "DMD" is defined in the environment, that will be the only
|
|
dnl dmd command tested. Otherwise, a hard-coded list will be used.
|
|
dnl
|
|
dnl After AX_DMD runs, the shell variables "success" and "ax_dmd" are set to
|
|
dnl "yes" or "no", and "DMD" is set to the appropriate command. Furthermore,
|
|
dnl "dmd_optlink" will be set to "yes" or "no" depending on whether OPTLINK is
|
|
dnl used as the linker (DMD/Windows), and "dmd_of_dirsep" will be set to the
|
|
dnl directory separator to use when passing -of to DMD (OPTLINK requires a
|
|
dnl backslash).
|
|
dnl
|
|
dnl AX_CHECK_D_MODULE must be run after AX_DMD. It tests for the presence of a
|
|
dnl module in the import path of the chosen compiler, and sets the shell
|
|
dnl variable "success" to "yes" or "no".
