gcc - Building exempi 2.x on mingw64 errors with gmtime_r(), readdir_r(), and realpath() -


i'm building exempi-2.4.3 (latest) in msys2/mingw64 on windows 10 dependency project.

./configure appears succeed, mentioning couple of warnings:

... checking sysroot... no ... checking mt... no checking if : manifest tool... no ... checking if gcc supports -fno-rtti -fno-exceptions... no ... checking toolset name used boost g++... configure: warning: not figure out toolset name use g++ ... checking valgrind/memcheck.h usability... no checking valgrind/memcheck.h presence... no checking valgrind/memcheck.h... no configure: warning: valgrind missing. checks run without ...

make giving me following errors:

  cxx      host_io-posix.lo host_io-posix.cpp: in function 'void convertposixdatetime(const time_t&, xmp_datetime*)': host_io-posix.cpp:126:2: error: 'gmtime_r' not declared in scope   gmtime_r ( &ostime, &posixutc );   ^~~~~~~~ host_io-posix.cpp:126:2: note: suggested alternative: '_ftime_s'   gmtime_r ( &ostime, &posixutc );   ^~~~~~~~   _ftime_s host_io-posix.cpp: in function 'bool host_io::getnextchild(host_io::folderref, std::__cxx11::string*)': host_io-posix.cpp:524:13: error: 'readdir_r' not declared in scope    int err = readdir_r ( folder, childinfo, &result ); // ! use thread-safe form.              ^~~~~~~~~ host_io-posix.cpp:524:13: note: suggested alternative: 'readdir'    int err = readdir_r ( folder, childinfo, &result ); // ! use thread-safe form.              ^~~~~~~~~              readdir host_io-posix.cpp: in function 'std::__cxx11::string host_io::getcasepreservedname(const string&)': host_io-posix.cpp:550:20: error: 'realpath' not declared in scope          systempath=realpath( inputpath.c_str() , null );                     ^~~~~~~~ host_io-posix.cpp:550:20: note: suggested alternative: '_makepath'          systempath=realpath( inputpath.c_str() , null );                     ^~~~~~~~                     _makepath make[1]: *** [makefile:477: host_io-posix.lo] error 1 make[1]: leaving directory '/c/users/dhkhodabakhsh/projects/exempi-2.4.3/source' make: *** [makefile:441: all-recursive] error 1

i tried changing

  • gmtime_r -> _ftime_s
  • readdir_r -> readdir
  • realpath -> _makepath

but it's not straightforward expected.

shouldn't mingw64 handle this? missing sort of library has these mappings?

android - InAppBilling registering BroadcastReceiver in AndroidManifest -

i'm implementing inapp billing in android app. works well, however, i'm trying decouple broadcast receiver activity manifest. suggestion in android's trivialdrive sample: // important: dynamically register broadcast messages updated purchases. // register receiver here instead of <receiver> in manifest // because call getpurchases() @ startup, therefore can ignore // broadcasts sent while app isn't running. // note: registering listener in activity bad idea, done here // because sample. regardless, receiver must registered after // iabhelper setup, before first call getpurchases(). currently there's class extends broadcastreceiver : public class iabbroadcastreceiver extends broadcastreceiver { /** * intent action receiver should filter for. */ public static final string action = "com.android.vending.billing.purchases_updated"; private final iabbroadcastlistener mlistener; public iabbroadcastreceiver(iabbroadcastlistener listener) { m...

python Tkinter Capturing keyboard events save as one single string -

is possible store keyboard events 1 string? code below stores 1 char , prints it. card reader or bar code reader, contains collection of character/ string not 1 character @ time. goal save char pressed text variable. from tkinter import * root = tk() def key(event): text= event.char text+= event.char print ("pressed", text) def callback(event): frame.focus_set() print ("clicked at", event.x, event.y) frame = frame(root, width=100, height=100) frame.bind("<key>", key) frame.bind("<button-1>", callback) frame.pack() root.mainloop() currently, creating text variable , everytime key() function gets called, , text stores last character typed. you can define text module level variable , , use module level text inside key function - text = '' def key(event): global text text+= event.char print("pressed", text)

sql server - Why does Linq-to-SQL add unnecessary COUNT()? -

here tables: create table customer ( cid int primary key, name varchar(32) ) create table ord ( oid int primary key, cid int foreign key references customer, address varchar(20) ) here's linq-to-sql statement: var aaa = c in db.customer select new { c, o = c.ord.tolist() }; and here's inexplicable query generated linq-to-sql: select [t0].[cid] [cid], [t0].[name] [name], [t1].[oid] [oid], [t1].[cid] [cid2], [t1].[address] [address], (select count(*) [dbo].[ord] [t2] [t2].[cid] = [t0].[cid]) [value] [dbo].[customer] [t0] left outer join [dbo].[ord] [t1] on [t1].[cid] = [t0].[cid] order [t0].[cid], [t1].[oid] i want understand how rid of count(*) part. it's entirely uncalled for! linq needs count(*) in order determine number of entries returned o = c.ord.tolist() .
