Hi,
I've just sent two patches to improve config.sub.
Yann Droneaud (2):
config.sub: use $name instead of $1
config.sub: be more liberal on input case: accept upper case name
ChangeLog | 10 ++++++++++
config.sub | 72
+++++++++++++++++++++++++++++++++++++-----------------------------------
2 files changed, 47 insertions(+), 35 deletions(-)
The rationale behind this is:
when using ./configure --host=<name>, --build=<name>,--target=<name>,
<name> is not the output of config.guess and can be written in
upper-case. For example ./configure --host=X86-LINUX
With the current config.sub, I'm getting:
$ ./config.sub X86-LINUX
Invalid configuration `X86-LINUX': machine `X86' not recognized
With the two patches, I'm getting a better result:
$ ./config.sub X86-LINUX
x86-unknown-linux-gnu
Some concerns:
- tr tool was not previously used in config.sub, but it is in
config.guess. If it cannot be used, perhaps sed -e
'y/ABCDEFGHIJKLMNOPQRSTUVWXYZ/abcdefghijklmnopqrstuvwxyz/' can be used
instead. But the 'y/' command is not used in config.guess: not portable
enough ?
- MiNT: the way MiNT was recognized seems a bit difficult to understand.
In uppercase it has a any prefix, but in lowercase it has a dash, but
not every time. Might be interesting to check for real.
Regards.
