Re: Crash in wxZipInputStream [SOLVED]

I see what you mean. It just crashed for me on attempt 9. I can't think of a solution in user-code either, but if you do find one please post it here!

Ideally it should be fixed in wxZipInputStream and I suggest you report the bug on trac, attaching the faulty zip.

Re: wxWebView refuses to build on Linux [SOLVED]

Hi, The configure and make commands complete without any errors Have a look in config.log, or scroll through the 'configure' output. It will probably tell you that --enable-webviewwebkit failed because of some missing dependency. That doesn't make 'configure' fail though, so ../configure && ...

Re: Crash in wxZipInputStream [SOLVED]

Hi, I get the same error message with 'zip -T', though (debian's) 'unzip' succeeds. My wxGTK program, 4Pane, can read and manipulate zip files and copes with your one without a problem. It reads into a memory buffer, first using a wxStreamBuffer. wxFFileInputStream in(filepath); wxStreamBuffer strea...

Re: Problem building wxWidgets on aarch64 (ubuntu)

Hi, I've no experience with aarch64 or arm64, but for recent ubuntu versions I see that the latter is now used for your device. so I installed the package for arm64, and it worked That sounds promising. Have you tried installing the arm64 xenial libwxgtk3.0-dev package (plus dependencies of course)?...

Re: compiling the widgets sample on ubuntu 16.04

Hi, makefile.unx isn't the one to use. What you should have done is to build in a subdir: mkdir build-dir && cd build-dir ../configure --<whatever> make -j There would then be a samples/ dir inside build-dir that will have a properly-configured 'Makefile'. as will each of the samples/foo/ I ...

Re: Uninstalling wxWidgets 3.0.2 [SOLVED]

I suspect it's more https://www.jetbrains.com/help/clion/auto-completing-code.html and https://www.jetbrains.com/help/clion/code-completion.html , but I'm not sure that theyt tell you how to set it up in the first place. Perhaps a Clion forum would be a better place to search, or ask...

Re: Uninstalling wxWidgets 3.0.2 [SOLVED]

This is what i get from wx-config --libs all ... That looks fine, and so is the synaptic image. To make sure I'm not misunderstanding you, what is now failing? Is it just the code-completion/intellisense issue, or do you have a build problem too. If the latter, please would you paste here the first...

Re: Uninstalling wxWidgets 3.0.2 [SOLVED]

You know the little green square in synaptic that tells you if that package is installed? Yes indeed. I marked all of them. I couldn't miss a package It depends on the search string. 'wx' would have caught wx3.0-headers but 'libwx' or 'wx-' obviously wouldn't. Anyway, it's unimportant now. Everythi...

Re: Uninstalling wxWidgets 3.0.2 [SOLVED]

Hi, wxWidgets in debianish distros like ubuntu comes in multiple packages. The libs are in libwx*30, the dev files in libwx*30-dev etc. But there are others too e.g. docs, examples and headers. The headers package is wx3.0-headers and installs to /usr/include/wx-3.0. Perhaps you missed that one when...

Re: any chart control for wxwidgets ?

Hi,

The only one I've heard of is wxChart, which is now unmaintained. However you shouldn't find it too hard to get it working with current versions of wxWidgets.

Regards,

Re: Error in compilation since yesterday without having modified anything

Hi, 1) I was going to ask where your .cpp file(s) were, as you don't seem to mention them; but doublemax has already said much the same thing, better. So: 2) This suggestion won't fix your current problem, but will save you from future ones: Don't put things like ' -I/usr/local/lib/wx/include/gtk3-u...

Re: Return Error -11 when running program

BTW in Tuesday's post you said the failing g++ version was 4.9. Today you are talking about 4.8. Was '4.9' a typo? Is there an incompatibility with ubuntu 16.04 and gcc v4.8? Very unlikely. And I have an old trusty virtualbox guest that uses gcc 4.8. Its wx-based programs build and run normally. It'...

Re: Return Error -11 when running program

Have a look in /usr/bin/. You may well have >1 versions of g++ installed. /usr/bin/g++ (and /usr/bin/gcc) are usually symlinks to one of those. In your case it may not be pointing at g++-4.9.

Re: Return Error -11 when running program

Then it is segmentation fault.

Make a debug build of the program if you haven't already done so. Then debug it in CodeLite. When the segfault happens, the backtrace should tell you what went wrong.

Re: Some kind of issue closing tabs!

Hi, wxWidgets wraps the native toolkit on each platform; for Linux that's (usually) gtk+. It's not unusual to get complaining messages from gtk, or in your case the Xfce theme engine. It doesn't usually signal a problem with user code. Does everything seem to work OK? If so, I should just ignore the...
