When changing SDKMACHINE, we may encounter an error forcing us to wipe the TMP folder. Since only SDK_ARCH is captured in the PN of the crosssdk recipes, changes to SDK_OS result in conflicts. Eventually we hit an error such as:
ERROR: meta-toolchain-1.0-r7 do_populate_sdk: The recipe meta-toolchain is trying to install files into a shared area when those files already exist. ... The build has stopped as continuing in this scenario WILL break things, ... you're advised to wipe out tmp and rebuild ... This patchset addresses the problem by using SDK_SYS as the recipe name suffix instead of SDK_ARCH. The patchest was successfully tested with the following sequences in local.conf: $ bitbake meta-toolchain SDKMACHINE = "x86_64-mingw32" SDKMACHINE = "x86_64" SDKMACHINE = "i686-mingw32" SDKMACHINE = "i686" SDKMACHINE = "x86_64-mingw32" $ bitbake core-image-minimal -c populate_sdk USER_CLASSES += " testsdk " SDKMACHINE = "x86_64" (passes testsdk: Ran 11 tests in 75.426s) SDKMACHINE = "x86_64-mingw32" SDKMACHINE = "i686" (passes testsed:Ran 11 tests in 82.831s) SDKMACHINE = "i686-mingw32" SDKMACHINE = "x86_64-mingw32" SDKMACHINE = "x86_64" $bitbake core-image-minimal -c populate_sdk_ext As there is no meta-mingw for master yet, I used this meta-mingw layer: http://git.yoctoproject.org/cgit/cgit.cgi/meta-mingw-contrib/log/?h=juro/master (The "master" is by definition a moving target, I used the poky commit a767c78abeb19a9d730e3c9b1f64c13fbbcade17 with the tests above) Juro Bystricky (1): SDK: Allow changing SDKMACHINE without wiping TMP folder meta/classes/base.bbclass | 2 +- meta/conf/distro/include/tcmode-default.inc | 12 ++++++------ meta/recipes-core/glibc/glibc-initial.inc | 2 +- meta/recipes-core/glibc/glibc.inc | 2 +- meta/recipes-core/musl/musl.inc | 2 +- meta/recipes-devtools/binutils/binutils-crosssdk_2.27.bb | 2 +- meta/recipes-devtools/gcc/gcc-cross-initial.inc | 2 +- meta/recipes-devtools/gcc/gcc-cross.inc | 2 +- meta/recipes-devtools/gcc/gcc-crosssdk-initial.inc | 2 +- meta/recipes-devtools/gcc/gcc-crosssdk.inc | 2 +- meta/recipes-devtools/gcc/libgcc-initial.inc | 2 +- 11 files changed, 16 insertions(+), 16 deletions(-) -- 2.7.4 -- _______________________________________________ Openembedded-core mailing list Openembedded-core@lists.openembedded.org http://lists.openembedded.org/mailman/listinfo/openembedded-core
