OGDF » Developer's Guide » Porting Guide » Dogwood
We no longer officially support compilers older than gcc 7, clang 6 or Visual Studio 2017 15.8 (MSVC 19.15). Further, we require CMake version 3.8 or newer. This allows us to ignore certain quirks of these older compilers and even make use of C++17 features in the future. Some parts of the OGDF may still be usable even when using older compiler versions, but we will not pay any extra effort to keep it that way.
ArrayBuffer::compactMemcpy() is removed in favor of ArrayBuffer::compactCopy(), which now automatically uses memcpy if the array elements are trivially copiable.
CoinManager::logging(OsiSolverInterface* osi, bool logMe) is removed in favor of updateLogging(OsiSolverInterface* osi),
which propagates changes made to the newly introduced ogdf::Logger CoinManager::CoinLog to the COIN logging facilities
in a more fine-grained way.
When using GraphAttributes with nodeId enabled, the GraphAttributes::idNode() method returns a given node's current
index (rather than the old default value of -1) if no user-specified index has been explicitly set.
Using read(G, "input.graphml") on a file that actually contains data in another format no longer works,
as we no longer try to auto-detect the file type if we can deduce it from the file's extension.
If you want the old behavior ignoring the file's extension, use read(G, "input.graphml", GraphIO::read)
to always try all known formats until one is found that successfully parses the file.
fmmm.useHighLevelOptions(true) no longer resets all low-level options (see the method's documentation for more information).
If you want to emulate the previous behavior, simply use fmmm.resetOptions(); fmmm.useHighLevelOptions(true);.
