problem with swt4-gtk update
Hi Emmanuel, With the latest update of swt4-gtk to 4.18.0-1 I am seeing a problem in loading the library. After a little debugging it seems its not finding a symbol. /usr/lib/jni/libswt-pi3-gtk-4940r23.so: undefined symbol: gdk_texture_new_from_file Then it tries to find "/usr/lib/jni/libswt-pi4-gtk.so" which is not present and so the application fails. Any ideas? -- Regards Sudip

'gdk_texture_new_from_file' is from gtk4 and the below patch will fix the problem. Do you want me to go ahead with this change ? diff --git a/debian/rules b/debian/rules index 803ce85a..f23618c4 100755 --- a/debian/rules +++ b/debian/rules @@ -2,7 +2,7 @@ include /usr/share/dpkg/pkg-info.mk -export DEB_CFLAGS_MAINT_APPEND=-fPIC +export DEB_CFLAGS_MAINT_APPEND=-fPIC -DNO_gdk_1texture_1new_1from_1file DEB_BUILD_MAINT_OPTIONS=hardening=+all include /usr/share/dpkg/buildflags.mk CFLAGS+=$(CPPFLAGS) -- Regards Sudip

So the modified patch is pasted below. But even if we add it to CPPFLAGS it will eventually get added to CFLAGS as d/rules is doing "CFLAGS+=$(CPPFLAGS)". diff --git a/debian/rules b/debian/rules index 803ce85a..5add19ce 100755 --- a/debian/rules +++ b/debian/rules @@ -3,6 +3,7 @@ include /usr/share/dpkg/pkg-info.mk export DEB_CFLAGS_MAINT_APPEND=-fPIC +export DEB_CPPFLAGS_MAINT_APPEND=-DNO_gdk_1texture_1new_1from_1file DEB_BUILD_MAINT_OPTIONS=hardening=+all include /usr/share/dpkg/buildflags.mk CFLAGS+=$(CPPFLAGS) -- Regards Sudip

Maybe, but it’s the semantically right thing after all ;-) Maybe the upstream build system will become unbroken one day and not require that any more, and then it’ll not need fixing up. bye, //mirabilos -- tarent solutions GmbH Rochusstraße 2-4, D-53123 Bonn • http://www.tarent.de/ Tel: +49 228 54881-393 • Fax: +49 228 54881-235 HRB 5168 (AG Bonn) • USt-ID (VAT): DE122264941 Geschäftsführer: Dr. Stefan Barth, Kai Ebenrett, Boris Esser, Alexander Steeg * Mit unserem Consulting bieten wir Unternehmen maßgeschneiderte Angebote in Form von Beratung, Trainings sowie Workshops in den Bereichen Softwaretechnologie, IT Strategie und Architektur, Innovation und Umsetzung sowie Agile Organisation.
