And also other problems found: When use PACKAGE_CLASSES = "package_deb", and the length of tmpdir is 177, the error is: /too/long/path/totmp/sysroots/x86_64-linux/usr/bin/dpkg-scanpackages: bad interpreter: No such file or directory The interpreter is perl, and it does exist, it seems that we should limit the length of tmpdir to a smaller value then 177 rather than fix these strange problems. I will go on working on it. // Robert On 06/19/2012 01:47 AM, Mark Hatle wrote: > We're not away of any size limitations within pseudo, other then PATH_MAX which > is typically 4096... > > --Mark > > On 6/18/12 4:17 AM, Robert Yang wrote: >> >> Hi Experts: >> >> I've met a strange issue, when set the length of builddir to >> 266 (Why I did this is that I need to know how long the tmpdir >> that oe-core can support): >> >> NOTE: package dbus-1.4.20-r3.0: task do_install: Started >> *** glibc detected *** groupadd: malloc(): memory corruption: >> 0x000000000101da70 *** >> *** glibc detected *** groupadd: malloc(): memory corruption: >> 0x000000000101da70 *** >> >> Then the build would hang, this is caused by the command: >> >> PSEUDO_PREFIX=/too/long/path/tmp/sysroots/x86_64-linux/usr >> PSEUDO_LOCALSTATEDIR=...
