Re: test in a m4 macro and variable created from pushdef

[Vincent Torri]

I have another problem, which is similar. The problem is the result of 
AM_CONDITIONAL. Here is my macro:



AC_DEFUN([AS_CHECK_DRIVER], [

pushdef([UP], translit([$1], [a-z], [A-Z]))dnl
pushdef([DOWN], translit([$1], [A-Z], [a-z]))dnl

AC_ARG_ENABLE([DOWN[]],
   AC_HELP_STRING(
      [--disable-[]DOWN],
      [Build VFlib without $2 font driver]
   ),
   [
      if test "x${enableval}" = "xyes"; then
         use_]DOWN[_driver="yes"
         AC_DEFINE(WITH_[]UP, 1, [$2 font driver support])
      else
         use_]DOWN[_driver="no"
      fi
   ],
   [
      use_]DOWN[_driver="yes"
      AC_DEFINE(WITH_[]UP, 1, [$2 font driver support])
   ]
)

AM_CONDITIONAL(BUILD_DRIVER_[]UP, test "x${use_]DOWN[}" = "xyes")

popdef([UP])
popdef([DOWN])

])



the first parameter is a word (driver name), the second is a string about 
the description of the sriver

I use it that way (for example):

AS_CHECK_DRIVER([bdf], [BDF])

the variable use_bdf is equal to "yes", but in my Makefile.am, when I use:

if BUILD_DRIVER_BDF
DRV_BDF_SRC = drv_bdf.c
endif

DRV_BDF_SRC is not set: in the Makefile, I can see:

#DRV_BDF_SRC = drv_bdf.c

I have tried to add brackets:

AM_CONDITIONAL(BUILD_DRIVER_[]UP, test "x${use_[]DOWN[]}" = "xyes")

but it does not work.

Does someone see why BUILD_DRIVER_* is not set ?

Thank you
