I'm trying to mix Qt and libVLC, I've downloaded libs, tried some tutorials, but I always stop on the same error and I can't find any solution in Google...
Here's the compilation output
error: unknown type name 'libvlc_exception_t'; did you mean 'libvlc_event_t'?
I'm running MacOS 10.8.4
EDIT : the libvlc_exception_t is not even documented on LibVLC Doc
That's why :
doc/ChangeLog-2010: The libvlc_exceptions have been removed from libvlc.

I am having trouble at getting the example "QuickJournal" to compile on iOS. The code compiles OK, but fails during the Fody step.
Goals
Try out the example application for .NET through the following
- Pull the repository
- Open the solution in examples/QuickJournal
- Compile and test
Expected Results
Smooth compilation & testing experience
Actual Results
Fody out of memory exception
Steps to Reproduce
See the setup, follow steps
I am using the latest Xamarin/Visual Studio Mac/XCode
Code Sample
The regular realm source code
Version of Realm and Tooling
git clone https://github.com/realm/realm-dotnet.git
git checkout 8f5e36ffd91e06b9c60b91f9de3fb312b411a4a4
The exception I am getting is
Fody: Found debug symbols at '~/realm-dotnet/examples/QuickJournal/QuickJournal/obj/Debug/QuickJournal.pdb'.
MSBUILD : error : Fody: An unhandled exception occurred:

Realm 1.2.1 addresses that by using an updated version of Fody.
Answer for older Realm versions:
This is caused by a Cecil bug with Mono 5.0. As Realm depends on Fody, which uses Cecil, compilation will fail for project referencing it. Until new Cecil and Fody versions are released, the workaround is to revert to Mono 4.8:
I'm using qt5.5 in linux and win7 (mingw32) ... in linux it works (i had to build new usblibs for compatibility reasons)
in windows using this library
/usr/local/.../code-qt/libusb-1.0.19-rc1-win/MinGW32/static/
i get the following errors and a few more, all with some
"_imp__SetupDixxxxxxx" being undefined
since the libusb build in windows seems quite more complicated, i was unable to figure out how to do it
at this point i have no clue what is wrong and any help is highly appreciated
i have no problems rebuilding the lib with ming32w inside or outside of qt5 creator or any other way, but i would need to have a few steps described on how to proceed.

You need to link additional libraries for windows, add in your .pro file:
win32 {
LIBS += -lhid -lsetupapi
}
after installing symfony 2.6 and when executing an error message is displayed:
FatalErrorException in DirectoryResource.php line 82:
Error: Undefined class constant 'FOLLOW_SYMLINKS'
the error is in the bundle: kriswallsmith
Please help me.
thank you in advance
Which versio of PHP are you running under? 5.2?
This sounds awfully similar to this issue report: https://github.com/caefer/sfImageTransformExtraPlugin/issues/5
The class constant, FOLLOW_SYMLINKS, is part of the RecursiveDirectoryIterator, which according to the PHP.net manual page, was added in 5.3.1 and also 5.2.11. At least version 5.3.9 is usually recommended or required by various frameworks because of various issues in prior versions.
The package is "kriswallsmith/assetic"
I'm trying to build an opensource code on windows.
I get the error:
Warning: QT_QMAKE_EXECUTABLE reported QT_INSTALL_LIBS as D;/Qt/4.8.4/lib
Warning: D**;**/Qt/4.8.4/lib does NOT exist, Qt must NOT be installed correctly.
CMake Error at /usr/share/cmake-2.6.4/Modules/FindQt4.cmake:640 (MESSAGE):
Could NOT find QtCore header
(this is only a part of the error message)
I tried to re-install Qt, didn't work.
I tried to change QT_INSTALL_LIBS to be D:/Qt/4.8.4/lib (and not D:/Qt/4.8.4/lib) in my computer -> properties -> advanced - > environment variables but that didn't seem to change a thing.
I have no idea what to do next. Does anyone know what I should do fix it?
I am trying to statically link a Qt library I am building to Botan using MSVC on Windows and am receiving the following error.
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(129) : error C2589: '(' : illegal token on right side of '::'
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(128) : while compiling class template member function 'void Botan::MemoryRegion<T>::copy(const T [],size_t)'
with
[

]
..\..\3rdparty\temp\botan-msvc\build\include\botan/buf_comp.h(41) : see reference to class template instantiation 'Botan::MemoryRegion<T>' being compiled
with

]
..\..\3rdparty\temp\botan-msvc\build\include\botan/secmem.h(129) : error C2059: syntax error : '::'
This does not occur with MinGW. It also occurs when I comment out all Botan-related code. What does this mean and how can I solve it - also why does it not occur with MinGW?
I was able to figure out the issue with help from Jack Lloyd's comment. Apparently something that's included through one path or another #defined "min". I just undefined it and my library compiles and links perfectly. Thanks Jack!
