find_cc

一个很不错的程序切片工具,希望大家来讨论以下,对测试人员很有帮助

#!/bin/csh -f
#
# find a path to a C pre processor
#

foreach dir ($path)
	if ($dir != "." ) then
		if (-e $dir) then
			cd $dir
			if (-e acc && ! $?accpath) then
				set accpath = $dir
			else if (-e gcc && ! $?gccpath) then
				set gccpath = $dir
			else if (-e cc && ! $?ccpath) then
				set ccpath = $dir
			endif
		endif
	endif
end
	if ($?accpath) then
		echo "# define CC " \""$accpath/acc"\"
	else if ($?gccpath) then
		echo "# define CC " \""$gccpath/gcc"\"
	else if ($?ccpath) then
		echo "# define CC " \""$ccpath/cc"\"
	else
		echo no C compiler found
	endif
