There is a conflict with make behavior and AC_CHECK_PROG macro behavior
(maybe) when prog. is aliased (OS: cygwin) :
for example:
$ type -a hhc
hhc is aliased to `/cygdrive/c/Util/Dev/htmlhelp/hhc.exe'
configure.ac:
AC_CHECK_PROG([FOUND],[hhc],[yes],[no])
if test "x$FOUND" = "xno"; then
AC_MSG_ERROR(['hhc' is required !])
else
AC_SUBST(HHC,hhc)
fi
configure:
checking for hhc... (cached) yes
Makefile.am :
$(CHM_FILENAME) : $(SUB_DIR)/index.hhp $(SUB_DIR)/index.hhc
$(SUB_DIR)/index.hhk
cd $(SUB_DIR) && $(HHC) index.hhp
make:
cd tdg/en/html && hhc index.hhp
/bin/sh: line 1: hhc: command not found
Why does AC_CHECK_PROG find hhc ?
