Hi Jean, it looks like __UCLIBC__ is what you're looking for. from my /usr/include/features.h: [...] /* This macro indicates that the installed library is uClibc. Use * __UCLIBC_MAJOR__ and __UCLIBC_MINOR__ to test for the features in * specific releases. */ #define __UCLIBC__ 1 thanks for your trouble. Let me know if you'd like to have the whole features.h file. cheers, Rob Urban You wrote: > > > > Is there a way we could detect the use of uClibc?
