c++ - Include another CMake Project as Library -

-

i have decided make c++-qt-gui c program (both languages don’t know), using kdevelop, in turn uses cmake.

the c source has no header, made one, , migrated structs it, declaration of function in c source need call.

the problem can’t call it, because either cmake doesn’t find c file (and hence definition), or, when add c source source set in cmakelists.txt, complains both main.cpp , c source file have main functions.

how tell cmake should make function c file available declared in header?

here it:

project(oregengui) cmake_minimum_required(version 2.6) find_package(qt4 required)  include_directories(${qt_includes} ${cmake_current_binary_dir})  set(oregengui_srcs oregengui.cpp main.cpp qrangeslider/qrangeslider.cpp) #as add oregengui/oregengui.c, won’t work because of main function qt4_automoc(${oregengui_srcs}) add_executable(oregengui ${oregengui_srcs}) target_link_libraries(oregengui ${qt_qtcore_library} ${qt_qtgui_library})

ps: don’t want change c source much, since independant project. guess developer accept introduction of header, not more.

i'm bit rusty on this, along lines of:

in oregengui.c

#if !defined myguiproj int main() { ... } #endif

in cmakelists want both in:

add_definitions( -dmyguiproj )

the compiler should ignore second main function.

java - SNMP4J General Variable Binding Error -

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
