The change in behaviour is from newer autoconf being used to generate the code tarballs. One of the reasons for that was to get better/easier cross-compiling support. > 2) are there any way to cross compile 3.3 (or 3.4)? You should only** have to specify the ./configure options to tell it which OS the compile is happening on (--build=X) and which OS type will run the binary (--host=Y). What exactly is the failure you are encountering? ** besides having the appropriate *-dev library versions installed for cross-compiling against and tools that can cross-compile. > 3) I read in the FAQ that from version 3.2 C++11 compilers is required, > I am using gcc 4.7.2, is it a supported compiler? Not required. "Preferred" is the word for it. We have code to make use of some C++11 only when available. Mostly we are taking advantage of the increased compiler code checking in our build farm to remove bugs before anyone notices them :-) The switch to mandatory C++11 support for general builds is still being discussed on squid-dev and IRC as to when the timing would offer least pain for everyonea and how long we can procrastinate on it. It might happen around Squid-3.6. Any GCC 4.0+ (excluding 4.5 with broken stdlib definitions of auto_ptr/unique_ptr) should work fine for Squid-3.2 and later. The later versions are better though with more general C++11 support benfits than the older ones. Cheers Amos
