most of the way thru the variable glossary and this one confuses me. from here:
http://www.yoctoproject.org/docs/latest/ref-manual/ref-manual.html#var-PACKAGECONFIG we have: "This variable provides a means of enabling or disabling features of a recipe on a per-recipe basis. PACKAGECONFIG blocks are defined in recipes when you specify features and then arguments that define feature behaviors. Here is the basic block structure: PACKAGECONFIG ??= "f1 f2 f3 ..." PACKAGECONFIG[f1] = "--with-f1,--without-f1,build-deps-f1,rt-deps-f1" PACKAGECONFIG[f2] = "--with-f2,--without-f2,build-deps-f2,rt-deps-f2" PACKAGECONFIG[f3] = "--with-f3,--without-f3,build-deps-f3,rt-deps-f3" which *seems* to suggest that you must first set PACKAGECONFIG to the list of features, but i see numerous examples that don't seem to obey that condition. from meta-oe/recipes-extended, this looks good: gnuplot/gnuplot.inc:PACKAGECONFIG ??= "cairo" gnuplot/gnuplot.inc:PACKAGECONFIG[cairo] = "--with-cairo,--without-cairo,cairo pango" this looks like it's missing a reference to "ftdi": lcdproc/lcdproc5.inc:PACKAGECONFIG ??= "usb" lcdproc/lcdproc5.inc:PACKAGECONFIG[usb] = "--enable-libusb,--disable-libusb,virtual/libusb0" lcdproc/lcdproc5.inc:PACKAGECONFIG[ftdi] = "--enable-libftdi,--disable-libftdi,libftdi" and this looks, well, totally wrong (at least according to the explanation in the manual): collectd/collectd_5.2.2.bb:PACKAGECONFIG ??= "" collectd/collectd_5.2.2.bb:PACKAGECONFIG[snmp] = "--enable-snmp,--disable-snmp --with-libnetsnmp=no,net-snmp" collectd/collectd_5.2.2.bb:PACKAGECONFIG[libmemcached] = "--with-libmemcached,--without-libmemcached,libmemcached" collectd/collectd_5.2.2.bb:PACKAGECONFIG[iptables] = "--enable-iptables,--disable-iptables,iptables" collectd/collectd_5.2.2.bb:PACKAGECONFIG[postgresql] = "--enable-postgresql,--disable-postgresql,postgresql" collectd/collectd_5.2.2.bb:PACKAGECONFIG[dbi] = "--enable-dbi,--disable-dbi,libdbi" collectd/collectd_5.2.2.bb:PACKAGECONFIG[modbus] = "--enable-modbus,--disable-modbus,libmodbus" collectd/collectd_5.2.2.bb:PACKAGECONFIG[libowcapi] = "--with-libowcapi,--without-libowcapi,owfs" collectd/collectd_5.2.2.bb:PACKAGECONFIG[sensors] = "--enable-sensors,--disable-sensors,lmsensors" so ... clarification? oh, and while i'm here, it's easy enough to use the "bb" utility to print PACKAGECONFIG: $ bb show -r gnuplot PACKAGECONFIG Parsing recipes..done. PACKAGECONFIG="cairo" $ but is there a way to display the value of PACKAGECONFIG[cairo]? "bb" doesn't seem prepared to do something like that. rday -- ======================================================================== Robert P. J.
