nanogui: Thread: compile microwin on uClinux

hi, all:
when I compile microwin on uClinux, I found some error like these:
memplan4.c(.text+0xdc4): undefined reference to `mips_io_port_base'
memplan4.c(.text+0xe7c): undefined reference to `mips_io_port_base'
memplan4.c(.text+0xec0): undefined reference to `mips_io_port_base'.

how could I do then? who have done the same works? can u give me some advise? thanks a lot.

regards

when I compile microwin on uClinux, I found some error like these:
memplan4.c(.text+0xdc4): undefined reference to `mips_io_port_base'
memplan4.c(.text+0xe7c): undefined reference to `mips_io_port_base'
memplan4.c(.text+0xec0): undefined reference to `mips_io_port_base'.

Typically this is because the outb() macro
has been called, and mips doesn't have one.
Set FBVGA=N in the config file, this should fix
it.

Greg - Thanks for jogging my memory.

The inb/outb inw/outw inl/outl functionality is broken for most uClibc 
implementations, so thats why you are getting problems.  I ran into the same 
problem with Strongarm.

I would suggest just setting FBVGA=N, because adding the required 
functionality in uClibc is non-trivial.

The only reason that outb() is required is for the VGA driver, something
no ucLinux systems have, regardless of the effort required.

The mapping is going to be board dependant. A typical non x86 board with
VGA will have the I/O space mapped into memory somewhere. So its just a case
of mmap()ing the right bit of /dev/mem and writing macros for it
