It finally worked (with OPT=-O- option added) You can test them at: ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/mipsel-linux/ or ftp://ftp.freepascal.org/pub/fpc/snapshot/trunk/mips-linux/ Please give feedback, I'm just about moving again here, but with a decided limp: the system that blew was 2.8GHz and all my guest OSes are now plugged into a 1GHz box. I still find being able to use a significant number of different guests in sleds/caddies useful... Unfortunately I've still not got any real MIPS hardware running here, so I'm still stuck on Qemu. The good news is that I can still run/build trunk for mipsel on Debian Squeeze on Qemu without unanticipated issues (i.e. nobody reading this should assume that Lazarus will work yet). The not-so-good news is that I built from trunk earlier but after having bus errors in Qemu's implementation of big-endian MIPS I'm now looking at the file above. Unfortunately I still get bus errors and I think the binaries have been stripped. This is very strange: I just installed the snapshot onto the big-endian mips machine that I use to generate the snapshot. This machine is the one that does generate daily testsuite results for mips-linux. I just tested a compiler cycle (with DEBUG=1) starting from this snapshot binary, and it seems to be able to generate a vanilla trunk ppcmips: ppcmips -iDW 2012/11/21 2.7.1-r1:23032 Is this a Qemu problem? But I see no other problems, except those that could be caused by slowness of the emulated environment (flush process timing out, which appears to be a known issue). I suggest you compile a null program and Hello, World! and upload them. This is one of the reasons that I'm trying to get at least one genuine SGI system running, I don't entirely trust Qemu as a reference platform. However booting Linux on the Origin 200 looks challenging, one Octane has a blown PSU and the other trips the RCD (suspect filter). -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

SVN logs (e.g. http://svn.freepascal.org/svn/logs/fpc-trunk.log if talking
about trunk)? As far as I understand SVN help correctly, querying the
revision for a specific date should be possible using 'svn -r {date} log',
but I haven't used it myself since I find working with the log files kept
in our SVN tree much more convenient.

I'll get back onto this later, I've got some Debian bugs to report :-/
But at the same time I note Pierre's
ppcmips -iDW
2012/11/21 2.7.1-r1:23032
Is there some reliable way of getting the SVN revision into the FPC
version number or build date, or even into a macro or symbol so that a
program can log what revision it was compiled by?

Execute once: touch compiler/revision.inc Afterwards, every time you build the compiler it will include the svn revision number in the extended version info.

I don't need any promise in fact, just to want to help a bit:) I'm happy to try helping :-) My colleagues and I have a policy of trying to do our bit to keep non-x86 systems viable because of their relative resistance to malware etc., so quite a lot of my (nominally) work time is spread out over various open-source projects. But neither I nor the company has much ready cash, which I why I often end up running on older kit which can be very frustrating at times. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
