Perhaps making a static proton would be a better solution. - Do the trivial arglist scanning manually instead of using getopt - Fix a change in include path missed in the test tools. > Add -fvisibility option when building shared libraries > --- > > Key: PROTON-250 > URL: https://issues.apache.org/jira/browse/PROTON-250 > Project: Qpid Proton > Issue Type: Improvement > Components: proton-c >Affects Versions: 0.3 > Environment: GNU Compiler >Reporter: Irina Boverman >Assignee: Andrew Stitcher >Priority: Minor > Labels: patch > Attachments: proton.patch > > > Add an option to "hide" symbols in shared libraries except when they are > declared public. > Extends efforts already in place for Windows builds. > Excludes an effort to determine what symbols should be considered "public" > interfaces. > The gcc 4 -fvisibility option is said to: > ...very substantially improve linking and load times of shared object > libraries, produce more optimized code, provide near-perfect API export and > prevent symbol clashes.
