Audacity does not build against wxWidgets compiled with STL
Last modified: 2019-07-28 11:13:31 UTC
This is because wxWidgets is built to use STL on openSUSE. There will be many errors of the form "cannot convert ‘const wxString’ to ‘const wxChar*". This is fixed (as confirmed by ThomasFeher) in jengelh's fork which is offered at https://github.com/audacity/audacity/pull/112. However that commit cannot be automatically merged because it is way behind HEAD.
As you can see at github, I thought this commit was too big, and by author's admission untested, to take all at once. And I am not sure that it changes no more than needed to fix the compilation. It should be broken into incremental commits in case anything is wrong and later could be more easily pinned down with a git bisect.
Apparently the STL version of wxWidgets 3.0.2 was an openSUSE experiment and their wxWidgets 2.8.x was non-STL, so I removed the "regression" flag. OpenSUSE have now made available a non-STL wxWidgets and released an Audacity 2.1.2 package, so demoted to P3, changed Platform to All and generalised title from "Audacity does not build on OpenSUSE using system wxWidgets" to "Audacity does not build against wxWidgets compiled with STL".
Thank you Gale for the work behind the scenes communicating with openSUSE people that led to the changes in status in comment#2. I'm not usually chatty in bugzilla, but this one merits it. With the bug retitled as a cross-platform STL issue, that opens the door to fix and resolution on a non SUSE platform - So a lower barrier to it being tackled.
David Plater reports (on audacity-devel) ----- Hi, I maintain Audacity in openSUSE. I'm trying to get version 2.3.0 to build but I'm getting the following error: widgets/NumericTextCtrl.cpp: In function 'size_t {anonymous}::ChooseNBuiltinFormatStrings(NumericConverter::Type)': widgets/NumericTextCtrl.cpp:554:45: error: cannot convert 'std::vector<BuiltinFormatString>' to 'size_t {aka long unsigned int}' in return return std::vector<BuiltinFormatString> {}; ----- From other comments it sounds like compiling wxwidgets without STL is one workaround - but not a workaround openSUSE would want to use, i.e. to close this bug we would need to adopt the ideas of https://github.com/audacity/audacity/pull/112
WORKSFORME i.e. Audacity builds on Windows, Mac and Ubuntu linux - the three officially supported platforms. This is therefore an enhancement request. It is not a bug against shipped audacity.
