linux - How to get rid of libthread_db -

-

on embedded file system, rid of libthread_db. understanding was necessary when debugging program using pthread. however, here observation :

  • if libthread_db not present @ boot time (when first pthread using programm launched), launching such program causes segfault.

  • adding libthread_db later (ie after pthread program has segfaulted) doesn't change anything. every program uses pthread segfault on launch.

so seems libthread_db essential run sort of program using pthread.

libthread_db never used threaded program. only used debugger.

your assertion libthread_db somehow required run program using pthreads incorrect. if pthread programs crash when libthread_db removed system, else broken on embedded target; removal of libthread_db merely triggers else.

you can trivially confirm this: build pthread program on regular linux system. run program under strace, , observe libthread_db not appear in strace output. rename /lib/libthread_db.so.1 else, , observe test program continues work fine.

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 .
