Cross compiling NetBSD current
Hi All, I am working on Compressed Cache project for NetBSD ( https://wiki.netbsd.org/projects/project/compressed-cache/) . I am trying to set up the cross compilation environment for NetBSD current. Copying tech-kern in this email since my emails to current-users seems to be not getting delivered). Host machine (where I am compiling): Ubuntu(64-bit) running on x86_64 Target architecture (where I intend to boot NetBSD): amd64 I am trying to compile tools using build.sh. Command used: /build.sh -U -m amd64 tools I see a bunch of compiler errors saying compilation terminated since a file was not found (#include sys/disk.h fails with file not found). Eventually the build fails with message ERROR: Failed to make build_install in tools. Attaching the last few lines of the build log. I was able to cross compile 6-1-4 release branch. hence I am guessing that I have all the necessary tools installed properly. Any help will be helpful and greatly appreciated.

Thanks! Works fine with the latest check out. -Vinay On Oct 4, 2014 5:00 AM, Manuel Bouyer bou...@antioche.eu.org wrote: On Fri, Oct 03, 2014 at 10:20:28PM -0400, Vinaykumar Bhat wrote: Hi All, I am working on Compressed Cache project for NetBSD ( https://wiki.netbsd.org/projects/project/compressed-cache/) .

A survey of what other OSes do would also be useful. Freebsd (and Dragonfly): CTLTYPE_NODEThis is a node intended to be a parent for other nodes. CTLTYPE_INT This is a signed integer. CTLTYPE_STRING This is a nul-terminated string CTLTYPE_S64 This is a 64-bit signed integer. CTLTYPE_OPAQUE This is an opaque data structure. CTLTYPE_STRUCT Alias for CTLTYPE_OPAQUE. CTLTYPE_UINTThis is an unsigned integer. CTLTYPE_LONGThis is a signed long. CTLTYPE_ULONG This is an unsigned long. CTLTYPE_U64 This is a 64-bit unsigned integer. OpenBSD has the same types as NetBSD, ie CTLTYPE_INT and CTLTYPE_QUAD as the int32 and uint64 types. I agree about being explicit with the 32 bitness, but using S64 and U64 as the 64 bit names to be consistent with FreeBSD might make sense. long types seems best avoided if possible, you can see the temptation to use them for memory amounts, but you could be running on 32 bit userspace on a 64 bit kernel.
