- Subject: GCC target for uClinux with uClibc
- Organization: Develer S.r.l.
in order to make some of the GCC patches acceptable,
I must avoid uClinux specific changes in the m68k-elf
The only solution is adding a new target specific to
uClinux, or uClibc, or both.
I was thinking about m68k-uclinux-elf or m68k-uclibc-elf.
Some of the constraints are:
- uClinux binaries must be linked differently
than m68k-elf binaries
- There are two C libraries for uClinux: uC-libc
(smaller) and uClibc (feature complete and highly
glibc compatible). Currently, I'm only supporting
uClibc, but someone might want to support uC-libc
in the future.
- I would like to keep configuring binutils as
"m68k-elf" because the uClinux specific patches
don't conflict with embedded targets.
- Preserving the original "m68k-elf-" prefix for
GCC binaries would make the transition to the
new toolchain less painful.
- libstdc++ really wants to know wether it's using
uClibc instead of glibc. It doesn't really matter
whether it's uClinux or some other Linux incarnation.
