during my “./configure”-installation of asterisk-16 on my QNAP TS-469L there are an error: “patch is required to configure bundled pjproject”.
The link from your Wiki (https://wiki.asterisk.org/wiki/display/AST/PJSIP-pjproject) to pjproject http://www.pjsip.org/release/2.6/pjproject-2.6.tar.bz2 dosn’t exist. The new version is 2.8. in a changed path.
The using of --with-external-cache dosn’t function. I try the Version 2.8 and 2.6, whereas I had to make the md5-hash for V2.6 by myself (with MD5FileHasher.exe under Windows).
What can I do to install asterisk completely?
