SDCC Update
^^^^^^^^^^^
I have had some problems building sdcc-2.6.0 on my current UBUNTU
release (9.10). I had other problems building sdcc-2.9.0 on UBUNTU 9.10.
I suspect that the newer gcc toolchains are causing problems for these
older SDCC releases.
A 20091106 snapshot did build with no major problems on UBUNTU 9.10, but
has some compatibilty problems with the older SDCC compiler. For one, you
will need to change the Z80 assember name and options in the Make.defs
files as follows:
-AS = as-z80
+AS = sdasz80
- @$(AS) $(ASFLAGS) $2 $1
+ $(AS) $(ASFLAGS) $1
For another, I had other problems building with that 20091106 that look
like compiler bugs. If you are using UBUNTU 9.10, you may have to either
(1) downgrade your GCC compiler to a version 3.x compiler and use one of
the older stable releases, or (2) wait for the next stable SDCC release
after 2.9.0.
