I was assuming that the toolchain mentioned was the cross toolchain since the target-native toolchain is treated like any other target package. > Which does not seem to be mentioned (or maybe the native > toolchain isn't mentioned). > > *) Downloads (either as required, or pre-downloads all (make source)) > *) Configures cross-compile toolchain > *) Builds cross-compile toolchain > *) Builds selected packages (optional) > *) Builds a native toolchain (optional, like any other "package") > *) Builds a kernel image (optional) > *) Creates a root filesystem in selectable forms (filesystem, archive, ...) > > Or something close to that - notice two (2) "toolchains" Right. I'll re-write that paragraph to use that list of steps. Just for the sake of curiosity, how often do people generate a target-native toolchain with buildroot? [I don't think any of the platforms I work with would have the resources available to use one.] -- Grant
