2013-04-08Clean up Makefile "warning" clutter when makeopts doesn't exist.Walter Doekes
Review: https://reviewboard.asterisk.org/r/2304 git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@384989 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2010-04-08Ensure that linker version scripts (used for symbol export control) always ↵Kevin P. Fleming
exist. Using wildcard matching in the Makefile is not adequate to determine whether an export file should exist for a module or not, so instead we'll just create one if the module needs one, or copy the default one if it does not. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@256428 65c4cc65-6c06-0410-ace0-fbb531ad65f3
2010-04-02Allow symbol export filtering to work properly on platforms that have symbol ↵Kevin P. Fleming
prefixes. Some platforms prefix externally-visible symbols in object files generated from C sources (most commonly, '_' is the prefix). On these platforms, the existing symbol export filtering process ends up suppressing all the symbols that are supposed to be left visible. This patch allows the prefix string to be supplied to the top-level Makefile in the LINKER_SYMBOL_PREFIX variable, and then generates the linker scripts as required to include the prefix supplied. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@255906 65c4cc65-6c06-0410-ace0-fbb531ad65f3
