Hi Saul, I'm sorry, but I don't quite understand what did you mean, I had sent pull request for it, and there is the discussion about the gcc's recipe, the pull request is in the oe-core, would you please take a look at it? And the title is: sanity.bbclass: check TMPDIR is not too long 22922 3 liezhi.yang 2012-07-10 01:56:57 +0000 Merged into master: http://git.yoctoproject.org/cgit/cgit.cgi/poky/commit/?id=2dee999ab2731c2a96e82762ae04fe44f27edac6 The length can not be longer than 410 currently. 23094 4 yi.zhao 2012-07-13 10:27:42 +0000 Verified with 1.3 m2 rc1. git info: eb0cb7e8234f5d2e5623406e9660be91cf52f65e Create a build directory, the length is longer than 410. Run "bitbake core-image-sato" will get following error message: ########## ERROR: OE-core's config sanity checker detected a potential misconfiguration. Either fix the cause of this error or at your own risk disable the checker (see sanity.conf). Following is the list of potential problems / advisories: The length of TMPDIR is longer than 410, this would cause unexpected errors, please use a shorter path. Failed to fetch test data from the network. Please ensure your network is configured correctly. ########## When the length of TMPDIR less than 410, "bitbake core-image-sato" can run without problem.
