Dragisa, I didn't change or break anything here.<BR>
<BR>
<BR>
You can use the older upgrade.sh, or you can do what Tony said. None<BR>
of the options seem to be well known, neither mine nor the old ways.<BR>
<BR>
<BR>
I find Tony's steps long and tedious, so much so that he made some mistakes below (sysutils<BR>
isn't in old releases, so needs to be in the first pass (and the second pass), m3cc is needed at some point).<BR>
Obviously others did too, as they where automated first in the *.sh files.<BR>
Who can remember that order?<BR>
<BR>
<BR>
I just made it all easier, automated, portable, maintainable. And I did it years ago.<BR>
For some definition of easier/automated/portable/maintable.<BR>
To me .sh is not maintainable, and .py is more portable -- I'd rather depend on Python than Cygwin.<BR>
Writing .sh that works across Linux, *BSD, Solaris, seems to be quite a battle. I can't remember all the rules for "how to write portable .sh" (see the Autoconf documentation), and I witness Olaf struggle with that too, I can hardly grasp the .sh language in the first place, and I suspect it is "overly string based", in the genre of severely flawed languages like cmd and Tcl. (Look at what '{' and '}' mean in Tcl. They aren't lexically scoping, as they appear to be, they are actually a string escape mechanism.)<BR>
However I still don't have OpenBSD/mips64 Python, and I use *.sh there (haven't been there in a while, small probably with libffi).<BR>
<BR>
<BR>
The automated builds use mostly *.sh, though making the .msis and .debs use Python.<BR>
<BR>
<BR>
Given a system<BR>
- not written in C <BR>
- with necessary circular dependencies <BR>
- that doesn't use make/autoconf <BR>
<BR>
<BR>
Not necessarily bad things any of them (circular dependencies are<BR>
just unavoidable), it's never going to be among the easiest to build. <BR>
<BR>
<BR>
Since I do occasionally go back to old releases, and find running cminstall annoying, I've made the current config files compatible with older releases. The .py scripts do upgrade them first. Where .sh probably doesn't.<BR>
<BR>
<BR>
We do provide prebuilt binaries, just that I don't always know where to get them<BR>
esp. up to date ones.<BR>

<DIV><BR></DIV>
<DIV>I too am a luddite and have never used any of Jay's scripts. I even still have essentially the same *old* monolithic config files on my system.</DIV>
<DIV><BR></DIV>
<DIV>Here is the general strategy.</DIV>
<DIV><BR></DIV>
<DIV>Take an old release.</DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV>Compile and ship the following in order...</DIV>
<DIV><BR></DIV>
<DIV>m3middle</DIV>
<DIV>m3objfile</DIV>
<DIV>m3linker</DIV>
<DIV>m3back</DIV>
<DIV>m3front</DIV>
<DIV>m3quake</DIV>
<DIV>cm3</DIV>
<DIV><BR></DIV>
<DIV>You now have a *new* compiler in cm3/TARGET/cm3 linked against the *old* libraries (m3core, libm3, sysutils).</DIV>
<DIV><BR></DIV>
<DIV>Now, compile and ship new libraries using the new compiler...</DIV>
<DIV><BR></DIV>
<DIV>m3core</DIV>
<DIV>libm3</DIV>
<DIV>sysutils</DIV>
<DIV><BR></DIV>
<DIV>And build a new compiler against the new libraries...</DIV>
<DIV><BR></DIV>
<DIV>
<DIV>m3middle</DIV>
<DIV>m3objfile</DIV>
<DIV>m3linker</DIV>
<DIV>m3back</DIV>
<DIV>m3front</DIV>
<DIV>m3quake</DIV>
<DIV>cm3</DIV>
<DIV><BR></DIV>
<DIV>You now have a *new* compiler in cm3/TARGET/cm3 linked against the *new* libraries.</DIV>
<DIV><BR></DIV>
<DIV>You should now be able to rebuild everything using the new compiler.</DIV>
<DIV><BR></DIV>
<DIV><BR></DIV>
<DIV>Hope this helps!</DIV>
<DIV><BR></DIV>
<DIV>-- Tony</DIV>
<DIV><BR></DIV>
<DIV>(PS Let me know if you have any problems with this. I have a feeling there are some tweaks I have made to the m3makefiles to make this go through smoothly.)</DIV>
