However: - ARG_MAX is not a standard definition, the code should be using getconf() to get this kind of value - The code uses ARG_MAX incorrectly. ARG_MAX is the maximum number of bytes occupied by arguments, but the code uses it as the max number of arguments. For the other two problems, I guess a bug should be reported to uClibc. I've Cc'ed Waldemar, uClibc-ng's maintainer. > diff --git a/package/passt/Config.in b/package/passt/Config.in > index fca1dff7c5..d06cc3e482 100644 > --- a/package/passt/Config.in > +++ b/package/passt/Config.in > @@ -1,5 +1,6 @@ > config BR2_PACKAGE_PASST > bool "passt" > + depends on !BR2_TOOLCHAIN_USES_UCLIBC I added a comment above this to explain why.
