<zewan> Hi all. Sorry for blunt question, but how to build lm8 toolchain? where can I obtain gcc source?
<ysionneau> ive never done any lm8 work
<ysionneau> only lm32
<ysionneau> i heard gcc is not awesome for 8bit micros
<ysionneau> gcc sources are on gcc website :) but i dont know if upstream gcc supports lm8
<ysionneau> maybe browse a little bit on lattice semi website
<ysionneau> they should provide a toolchain
Padawan- has joined #milkymist
<zewan> ysionneau, they provide toolchain in binary format but it's not work for me. And yes: upstream is not supports lm8
Padawan- is now known as Guest39589
<ysionneau> you say it does not work?
<ysionneau> could you elaborate?

<zewan> ysionneau, Of course. First of all, they deliver the toolchain in RPM format. After unpacking lm8-elf-gcc swears by the absence libgmp.so.3 library.

<wpwrak> if they've ported gcc, there must be the sources somewhere, too. else, tell rms and he'll hunt them down personally ;-)
<wpwrak> there ought to be a pointer on the download location, a README, or similar
<wpwrak> if not, just ask them politely. it's very unlikely that they'd intentionally try a blatant gpl violation
<ysionneau> zewan: do you have a file "libgmp.so.*" in your computer?
<ysionneau> maybe you need to search for it and tweak your LD_LIBRARY_PATH or do a symbolic link
<ysionneau> or install a package from your distribution
<ysionneau> if all of this fail, indeed you can follow wpwrak advice (README / ask them)
<zewan> ysionneau, my libgmp.so newer version and 64bit. Toolchain won't acceps it.
<ysionneau> wo
<ysionneau> is it a 64bit RPM ?
<zewan> yes
<ysionneau> ah, then you're lucky
<ysionneau> sometimes they only provide a i386 binary :)
<zewan> it hard to say that I'm lucky :)
<ysionneau> then maybe install an old enough RPM based distribution in your favorite virtualization software
<zewan> or write code in pure asm
<lekernel> ask lattice if you can't find the source. it would be nice to have it anyway.
<ysionneau> if you have binutils for lm8 then why not :)
<ysionneau> yes
<ysionneau> on their LatticeMico8 tutorial they give RHEL 4.0 or 5.0 requirement
<lekernel> just ignore and compile gcc yourself. those requirements are a pain.
<lekernel> you can also try navre, an AVR-compatible softcore I've developed
<lekernel> most distros package avr-gcc
<ysionneau> it seems that modern gcc have dropped support for lm8 (or maybe it has never been supported upstream?) : http://gcc.gnu.org/install/specific.html
bhamilton has joined #milkymist
<zewan> lekernel, how much your navre IP core allocated slices or LEs?
bhamilton has quit [Client Quit]
<ysionneau> zewan: what is your target FPGA?
<ysionneau> zewan : a few informations about navre http://opencores.org/project,navre
<ysionneau> it has been tested mostly on Spartan6 and I presume the numbers you fill find on this page are for synthesis with Spartan6 target
<ysionneau> ah yes it's written.
<zewan> ysionneau, EPM1270
<ysionneau> ok, I'm not familiar with altera chips
<ysionneau> but the core is small
<lekernel> zewan, something like 900 LUTs iirc
<lekernel> if you want extreme area optimization, look at J1
<lekernel> it's also pretty fast. but uses a weird programming language.
<zewan> lekernel, thanks. I'll see.
<zewan> ANS forth? WTF?
<lekernel> well, yes. :)
<lekernel> it seems to work nicely though
zewan has left #milkymist [#milkymist]
<ysionneau> I think somehow #milkymist is doing part of Lattice's hotline job :)
<larsc> I think they recently closed their support forums
<ysionneau> oh really?
<ysionneau> strange...
