But rewriting valid | FOO!=n to (FOO=y || FOO=m) doesn't sound like an improvement. Hm, I've thought that config selections were either boolean or tristate. This makes it sound like they could be quadstate (y/n/m/blank). And the menu dependency doc in Documentation/kbuild/kconfig-language.txt makes it sound (to me) like undefined values become 'n': Expressions are listed in decreasing order of precedence. (1) Convert the symbol into an expression. Boolean and tristate symbols are simply converted into the respective expression values. All other symbol types result in 'n'. ... An expression can have a value of 'n', 'm' or 'y' (or 0, 1, 2 respectively for calculations). A menu entry becomes visible when it's expression evaluates to 'm' or 'y'. -- ~Randy --- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 ___ kbuild-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kbuild-devel

[kbuild-devel] howto define one var. to another's value (y/n/m)
Hi, I see this in drivers/parport/Config.in (2.4.19) [not picking on parport; this occurs in many places]. define_tristate CONFIG_PARPORT_PC_CML1 $CONFIG_PARPORT_PC gcml2 (Greg Banks) checker program flags this with: warning:drivers/parport/Config.in:18:symbol "CONFIG_PARPORT_PC_CML1" defined to non-literal expression "CONFIG_PARPORT_PC" and indeed linux/Documentation/kbuild/config-language.txt says that 'define_tristate' takes a value of y, m, or n. [and not variables that have those values, right ??] Is there a simple, clean way to assign one tristate value to another one? Instead of having to do something like: if [ "$CONFIG_PARPORT_PC" = "y" ]; then define_tristate CONFIG_PARPORT_PC_CML1 y else if [ "$CONFIG_PARPORT_PC" = "m" ]; then define_tristate CONFIG_PARPORT_PC_CML1 m fi fi Thanks, -- ~Randy "In general, avoiding problems is better than solving them." -- from "#ifdef Considered Harmful", Spencer & Collyer, USENIX 1992. --- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf ___ kbuild-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/kbuild-devel
