copy - Using NSOpenPanel and copying selected file - Objective-C -


i'm trying create app copy selected sound file app's directory. it, i've written following code : 

nsopenpanel* opendlg = [nsopenpanel openpanel]; [opendlg setcanchoosefiles:yes]; [opendlg setallowsmultipleselection:no]; [opendlg setcanchoosedirectories:no]; [opendlg setallowedfiletypes:[nsarray arraywithobjects:@"aif",@"aiff",@"mp3",@"wav",@"m4a",nil]];  if ( [opendlg runmodalfordirectory:nil file:nil] == nsokbutton ) {     nsfilemanager *filemanager = [nsfilemanager defaultmanager];     nserror *error;      nsstring *datapath = [[nsbundle mainbundle] bundlepath];     nslog(@"datapath %@", datapath);     nslog(@"selected files : %@",[[opendlg urls] objectatindex:0]);     if ([filemanager fileexistsatpath:datapath] == no)     {         [filemanager copyitematpath:[[opendlg urls] objectatindex:0] topath:[[nsbundle mainbundle] bundlepath] error:&error];         nslog(@"file copied");      } }

the problems can select each types of files (not aif, wav, mp3 etc.) , never file copied. although, paths correct. when delete if statement, error saying : [nsurl filesystemrepresentation]: unrecognized selector sent instance 0x1005a0b90. what's wrong in code?

you're passing nsurl api expects path in nsstring. might consider using url-based api:

- (bool)copyitematurl:(nsurl *)srcurl tourl:(nsurl *)dsturl error:(nserror **)error ns_available(10_6, 4_0);

like this:

[filemanager copyitematurl: [[opendlg urls] objectatindex:0] tourl: [nsurl fileurlwithpath: [[nsbundle mainbundle] bundlepath]] error:&error];

also, i'm guessing file has been copied bundle since description indicates [filemanager fileexistsatpath:datapath] returning no (since nslog never executed.) can either check manually, or can ask nsfilemanager delete existing file before copying in newly selected file.

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
