c - Cross compiling libcurl and openssl for A9331 -



using dragino product arduino yun running openwrt linino iot related project. data arduino part , send json firebase db using libcurl (and https) in c program on openwrt part.
have managed setup cross-compiling toolchain ar9331 , can compile simple programs relying on libc. need cross compile libcurl ssl support in order send data firebase https. means need crosscompile openssl. however, not sure option have pass configure script in order set correctly. can compile static library openssl , curl program doest have dependency ? or bad practice ?

in last attempt compile openssl with:

./configure  --prefix=$(realpath $libpath)/openssl  linux-mips32

where $libpath location of lib in toolchain. makes returns following :

apps/speed.o: in function `speed_main': speed.c:(.text+0x4424): undefined reference `aes_set_encrypt_key' speed.c:(.text+0x443c): undefined reference `aes_set_encrypt_key' speed.c:(.text+0x4454): undefined reference `aes_set_encrypt_key' speed.c:(.text+0x7530): undefined reference `aes_encrypt' speed.c:(.text+0x7544): undefined reference `aes_encrypt' ./libcrypto.so: undefined reference `aes_set_decrypt_key' ./libcrypto.so: undefined reference `getcontext' ./libcrypto.so: undefined reference `setcontext' ./libcrypto.so: undefined reference `makecontext' ./libcrypto.so: undefined reference `aes_decrypt' collect2: error: ld returned 1 exit status makefile.shared:180: recipe target 'link_app.gnu' failed

how can compile openssl ar9331 ? if try add host flag architecture not recognised.

edit: maybe best method avoid dependencies problem create ipkg package (openwrt package manager)
try , inform if works.

those packages should present in openwrt default. have tried downloading them opkg? maybe have check repos pulling from.

as last resort can download openwrt source code , build 2 packages , .ipkg device, openwrt build system takes care of getting toolchain , building you.

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)

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
