Re: [Qlandkartegt-users] ECW files
Hi Oliver, I have found a solution. I was still using version 3.3 of the ECW library since it is the last release for which source files are available: it compiles, it links,... but it doesn't work. :-( Thus, I have downloaded the latest version of the ECW library (Release 5.0.1). Unfortunately, only binaries are available and the installer only extracts the files (it does not install them). Thus, I have manually installed the library according to the following procedure $ cd /usr/local $ sudo cp -r /(path to ecwjp2_sdk)/etc/ ./ $ sudo cp -r /(path to ecwjp2_sdk)/include/ ./ $ sudo cp -r /(path to ecwjp2_sdk)/lib/ ./ $ cd ./lib $ sudo ln -s ./x64/release/libNCSEcw.so.5.0.1 libNCSEcw.so or, depending on your architecture, $ sudo ln -s ./x86/release/libNCSEcw.so.5.0.1 libNCSEcw.so $ sudo ldconfig Then, I downloaded and compiled gdal-1.10.0 by following the usual procedure cd /(path to gdal) ./configure --with-ecw=/usr/local make sudo make install (or checkinstall) Finally, I compiled QLGT and... I'm newly able to open ECW files!! I hope it can be useful for someone else. Corrado Hi Corrado, I see. Looks like I have to find the time to compile a GDAL version with ECW support. Do you have a small ECW example file for me? Oliver Hi Oliver, yes, it crashes even without any initial config file, but only when I try to open an ECW map (no problem with other kinds of maps). In the past I was able to open ECW maps without any problem. Corrado Hi Corrado, thus even a plain installation of QLGT (no initial config file) crashes? I tried it myself by moving the QLGT config folder out of scope and QLGT started without a problem with it's initial state. Oliver Hi Oliver, Hi Corrado, I have verified that SQLite3 is installed. I have also found an installed package that is named libqt4-sql-sqlite (SQLite3 database drive for QT4): is it the plugin you were talking about? The pathGeoDB is pointing to my home directory, while it should point to...? Any valid path should do. In the path you will find a file named qlgt.db. This should have the correct access rights. Maybe the file is corrupted. In this case it's a good idea to move it. QLGT will create a new one. something has changed (now QLGT reads the database), but the program still crashes with this message use config file: Warning: Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there. terminate called after throwing an instance of 'std::length_error' what(): basic_string::_S_create In order to be sure that old configurations are not the reason of the crashes, I have also removed the $HOME/.config/QLandkarteGT directory, but the result is still the same. Cordially, Corrado Oliver I have forgotten to mention that I have no problems with vector maps. Many thanks, Corrado Hi Corrado, are SQLite3 and the Qt plugins for database support installed. On some distributions the plugins are a standalone packet. Another problem might be a bad database path configured in QLGT. Watch out for the [environment] section in the configuration file. The path is stored in pathGeoDB. Anyway I do not think it's a problem related to ECW. The exception is thrown in QSqlQuery and that is used in the QLGT's database. HTH Oliver Hi Oliver, yesterday I tried to open an ECW file... and I discovered that I'm no more able to open it. Not only, QLGT crashes if I try. I have recompiled GDAL 1.8.1 and GDAL 1.10.0 by enabling the ecw option, but it has not solved the problem. I also recompiled QLGT by starting from the repository version... same result. This is the message I get when QLGT crashes Warning: QSqlQuery::exec: database not open Warning: Qt has caught an exception thrown from an event handler. Throwing exceptions from an event handler is not supported in Qt. You must reimplement QApplication::notify() and catch all exceptions there. terminate called after throwing an instance of 'std::length_error' what(): basic_string::_S_create Can you please help me?
