linux - compiled C file not executable -


So when I try to run a compiled program on my school's "Hercules" server, Expect service me However, I've got an assignment for which to use the fork is necessary, and running a program that the fork is denied on that server, instead, I'm running it from remote machines connecting and running from several Linux machines , From the command line

However, any attempt to do this gives me this error: 

  shell2: Exec format error The binary file is not executable   
 Overall, my command prompt looks like this:  
  a049403 [8]% shell2 shell2: Exec format error . The binary file is not executable   
 The shell file is found in the directory I have working in, when I type "ls", it shows it with the * character, indicating Does that make it executable. I have tried to set my permissions for 777. This generates the same error for other C programs which I was working and was running, and "Hercules" could run the exact same file without any difficulties or complaints. My make file for this special event looks like this:  
  All: Shell2 Basics.O: Basics C Basics. Cc-C Basics Doublinked.o: doublelinked.c doublelinked.h cc-c double-linked.q. head.o: main c basics.h. Double-Linked. CC-C main c. Shell2: Main.o Basics.O Double Linked To CC Main.o Basics.O Double Linked.O-O Shell 2 Clean: Rm -f * o shell2   
 ... and If I run the makefile again, then it seems that there is no problem.  
 So, the reasons why an environment that can compile a program will not be able to run them? Any possible remedy?   
 
 
 First of all, your  makefile  is not very good to look and correct it for.  
 Then, a possible explanation  
  
 
 
 
 
  
 Why your binary The  libc  version may not be mismatched on the program target machine. Or maybe a system is 32 bits and the second is 64 bits. Use  file shell2  to find out.  
 I suggest that the target machine on  clear  then recompile it again (such as  all ).  
 Learn how.

c - Mpirun hangs when mpi send and recieve is put in a loop -

I was trying to use the program to use mifrewan on 4 node clusters. Distributing node 0 data in nodes 1, 2 and 3. In the program, from '90 'to variable values ​​of' dior 'to be calculated. Therefore the node is distributing data and collecting results in an omitted fashion (for different values ​​of var 'dir') when do {*******} Whereas (dir Loop is given, Mippun is hanging, and no output is found. But when I comment on two {*******} (dir The loop output is obtained for the initial value of variable dir dir = -90 ), and that output is correct. The problem occurs when the loop is given. Can anyone help me in solving this problem. #include "mpi.h" int main (int argc, char * argv []) Float dir = -90; Int rank, nanoprakash; MPI_Status status; MPI_Init (& amp; argc, & argv); MPI_Comm_rank (MPI_COMM_WORLD, & amp; Rank); MPI_Comm_size (MPI_COMM_WORLD, & amp; numprocs); If (rank == 0) {/ / data to begin / / (dest = 1; dest ...

python - Apply coupon to a customer's subscription based on non-stripe related actions on the site -

I can not find anything in the source about using coupons after subscribing to a user's plan. Is it possible to use a coupon to credit a user's membership after initial subscription? If not, what is the best option? Specifically, I want to give a user 100% coupon for that month, when they take 5 [site specific actions]. This is possible, but may not be the best idea. Coupons are currently applied to the stripe, then apply again at the customer level and each client can have a single coupon. So if you are already offering discounts to the coupon, then the customer who is currently in the present will also give up. It also means that if you are using a recently-added multiple subscription capacity, then all of the user's subscription will be ready for the month. Coupons can be set to "Once", only once (as the only name) can be used by any customer, so if this credit can earn more than once, You will have to maintain a 100% discount coupon continuousl...
