Hi Mark, Thanks. Still no luck, here I am explaining in detail. Hi,
My objective is to create a shared library and link it with app and call some APIs of dll in the app. Platform Details: ----------------------- Qt for Symbian 4.6.0 Qt Creator 1.3.0 S60 5th edition Abld is build system Below are the steps followed and issued faced. 1. Creating "App" I created an app called "MyApp" using Qt-Creator "Qt4 Gui Application" option. Default tool chain used to build is GCCE and able to build it. 2. Creating "Shared Library" I created a shared library called "MyDLL" using Qt-Creator option "C++ Library" then "Shared Library". Default tool chain is GCCE and able to built it. 3. Link "Shared Library" with "App" I don't find any good documentation of how to do this, the whole sequence of steps needed. I figured that LIBS needs. Added below line to MyApp.pro file LIBS += -lMyDLL.dll as suggested by qmake help, then building the app gives error make[2]: *** No rule to make target `\S60\devices\S60_5th_Edition_SDK_v1.0\epoc32\release\armv5\LIB\MyDLL.dso', needed by `\S60\devices\S60_5th_Edition_SDK_v1.0\epoc32\release\gcce\udeb\MyApp.exe'. Stop. make[1]: *** [TARGETMYAPP_0XE25A8EF2] Error 2 Question is : I am working with tool chain GCCE, why make is looking into ARMV5 path?. i.e. `\S60\devices\S60_5th_Edition_SDK_v1.0\epoc32\release\armv5\LIB\MyDLL.dso 4. Trying to work with Tool chain ARMV5 First, I want to build the MyDLL with Armv5. I created a new project settings with tool chain as ARMV5, then build MyDLL. Following error occrued Error: C0000U: Unrecognized option '--visibility_inlines_hidden'. make[2]: *** [\S60\devices\S60_5th_Edition_SDK_v1.0\EPOC32\BUILD\Qt-Projects\DLL\MyDLL\MYDLL_0XE11197E8\ARMV5\udeb\mydll.o] Error 1 make[1]: *** [TARGETMYDLL_0XE11197E8] Error 2 The generated MyDLL_0xE11197e8.mmp file has the line OPTION ARMCC --visibility_inlines_hidden --fpu softvfp I feel, creating a library is a very basic thing and it should be very easy for any body to do. There should be a single wiki page explaining all the steps with code whereever possible. I feel we should have detailed docmentation for Static Library, Shared Library and Plugins with code examples. Let me know if I miss any thing... -Krishna.
