Look at the rest of the toolchain-external/Config.in for examples. The supported architectures should also be mentioned, but that may be more difficult. > >>> + >>> +config BR2_TOOLCHAIN_EXTERNAL_CODESOURCERY_NIOSII201305_43 >>> + bool "Sourcery CodeBench Nios-II 2013.05-43" >> >> >> Why do you want to support two patchlevels of the same base version? >> > > Not sure, actually.

We do usually keep an older version around as well, but I'm not really sure why. For the Sourcery toolchains it makes sense because they have different gcc versions, but the Linaro toolchains often only have bugfixes between one version and the next. Regards, Arnout

Usually, all the Sourcery CodeBench toolchain have a document in share/doc/<tuple>/pdf/getting-started.pdf with many details about the toolchain. Otherwise: * nios-linux-gcc -v * nios-linux-gdb -v * find . -name 'ld-*.so' will identify which ld-2.xx.so, which will tell you the version of glibc > > Why do you want to support two patchlevels of the same base version? > > > > Not sure, actually. Just added all the options currently available. Hum? > Do you think is silly? Should I leave the latest one alone? You can support multiple versions, but not multiple patchlevel of the same version, because it's silly. Since I know you know how kernel versions work, what you did is like supporting 3.10.6 and 3.10.7: it's pointless, 3.10.7 is basically the same as 3.10.6 with a few additional fixes. Of course, supporting both 3.9 and 3.10 might make sense. Look at the other Sourcery Codebench toolchain entries in Buildroot. We support multiple versions, but not multiple patchlevel of the same version. Thanks! Thomas

Any recomendations on how to *choose* a toolchain? Should I safely use Sourcery? Should I prefer Buildroot internal (when we add support for it)? Which should be the rationale behind such decision? (aside from the fact the buildroot toolchain allows to be tuned) Thanks a lot for the help!

(aside from the > fact the buildroot toolchain allows to be tuned) External toolchain has the advantage that you don't have to spend time (about an hour) on building it. Internal toolchain has the advantage that it is configurable, and can be uClibc based and therefore smaller. The difference between uClibc and glibc is in the order of 1MB, so it only really makes sense when you want a really small rootfs. Regards, Arnout
