[ECOS] Does anybody know whether eCos has these functions??

[grachel]

I run into some errors like"undefined reference to..." when I plant phoneme
advanced to eCos platform.The mentioned functions are
'realpath','ftruncate','getrlimit','nl_langinfo','getpwuid','tzset','utimes','chmod'.I
don't know whether eCos supports all these functions.Can anybody give me
some suggestions?If eCos does support all these functions,where can I find
them?Thanks in advance!

Many of these functions don't make sense in an deeply embedded system.
eg getrlimit, nl_langinfo, getpwuid, utimes.

realpath and ftruncate were i think originally BSD extensions. eCos
tries to be POSIX compliant. It does not have these functions.

Are you talking about https://phoneme.dev.java.net ?  You want to be
careful about the licence.

Thank you!Indeed, I post almost the same thread on
https://phoneme.dev.java.net,just because I'm not sure what all these
functions come from.I'm now working on both phoneme advanced and eCos,and my
job is to plant all the phoneme codes to eCos platform,but when I link
cvm,these errors appear,so I have to try all the manners I can to settle
it!Thank you again!
