PropGCC on Fedora 15/16

Martin Hodge

Fedora 15 (x86_64): Successfully installed, compiled demos and run fibo on a Propeller.

Had to install glibc-2.14-5.i686 to get ld-linux.so.2

Congratulations.

Someone said you have a 64KByte EEPROM on the ASC. Can you confirm that?

If true, you will be able to run smaller XMMC demos from the EEPROM.
While the main program will not be very fast, all the other COG code will run full speed.
I have run programs with code size about 54KB and data/stack in HUB of 24KB on a 64KB EEPROM.
That is: 54K + 24K = 78KB total. With a 128KB EEPROM you can run David's xbasic.

Thanks,

Yes, confirming, 64KB on the ASC+.

Very strange... is this with the rebuild.sh script? It looks like it's failing during the libstdc++ build. I'm not seeing that problem on my Ubuntu machine. I'll try to find a Fedora machine to test this on. Could you file an issue in google code, please?

As a work-around you can skip the libstdc++ build by using the old rebuild.sh script.

This is likely missing packages on my machine. Don't fret over it yet.

-edit-

Today's commit fixed this issue. Noted on Google code as well. I will use the issue system for this type of thing from now on.
