Xcode - how to see build command and log?

假如想象 提交于 2019-11-28 20:04:39
I have build errors in my Xcode project (Objective-C), and I no longer "stumble upon" the build command string nor the build output logs. This is Xcode 6.3.1. All I can inspect is a left-side panel listing errors/warnings. I want the build command and build console output to compare between two projects; there's a platform-specific issue present in one but not the other; my intuition says that the build settings are different between the two and that seeing the output would be the easiest way to identify the diff. How do I get to see the build command string, and, the build output logs in this

Using sockets in Swift like in Java

纵然是瞬间 提交于 2019-11-28 17:56:37
问题 If I wanted to connect to a server, in Java I would open a Socket and initialize it with port and host address, then retrieve the input/output streams and read/write whatever I want. In Swift I'm having hard time doing so since it's not built that way and I would really like to see a simple example of how to connect to a server, retrieve the streams and use them. EDIT1: This is the tested code after what @Grimxn referenced. var host = "http://google.com" var readStream :CFReadStreamRef var

问题 I have a data.frame df with 600+ variables. I'm writing a function that automates the creation of columns and need to visually check them once. The str function provides a good summary: str(df) 'data.frame': 29 obs. of 602 variables: $ uniqueSessionsIni: POSIXct, format: "2015-01-05 15:00:00" "2015-01-05 16:00:00" "2015-01-05 17:00:00" ... $ uniqueSessionsEnd: POSIXct, format: "2015-01-05 15:59:00" "2015-01-05 16:59:00" "2015-01-05 17:59:00" ... $ m0p0 : POSIXct, format: "2015-01-05 15:00:00"

Where does the slf4j log file get saved?

喜夏-厌秋 提交于 2019-11-28 17:24:25
I have the followed imports: import org.slf4j.Logger; import org.slf4j.LoggerFactory; and the following instantiation: private static Logger logger = LoggerFactory.getLogger(Test.class); and the following in my Main method: logger.info("SOME MESSAGE: "); However, I'm not able to find the output anywhere. All I see is that in my console there is: 21:21:24.235 [main] INFO some_folder.Test - SOME MESSAGE: How do I locate the log file? Note that the following are on my build path: slf4j-api-1.7.5.jar slf4j-log4j12-1.6.4.jar I read the answer to similar questions but nobody actually says how to fix

C Temperature Conversion Program Keeps Outputting 0 For Fahrenheit to Celsius [duplicate]

别说谁变了你拦得住时间么 提交于 2019-11-28 14:44:37
This question already has an answer here: C program to convert Fahrenheit to Celsius always prints zero 8 answers My temperature conversion program in C keeps outputting 0 when I attempt to convert Fahrenheit to Celsius. The conversion from Celsius to Fahrenheit seems to work just fine. I have done the exact same thing for both functions and portions but I keep getting 0 for the second conversion. Can someone please help me or tell me what I am doing wrong? #include <stdio.h> //Function Declarations float get_Celsius (float* Celsius); //Gets the Celsius value to be converted. void to

Variable format

大城市里の小女人 提交于 2019-11-28 14:23:28
I wrote a program to calculate a square finite difference matrix, where you can enter the number of rows (equals the number of columns) -> this is stored in the variable matrix. The program works fine: program fin_diff_matrix implicit none integer, dimension(:,:), allocatable :: A integer :: matrix,i,j print *,'Enter elements:' read *, matrix allocate(A(matrix,matrix)) A = 0 A(1,1) = 2 A(1,2) = -1 A(matrix,matrix) = 2 A(matrix,matrix-1) = -1 do j=2,matrix-1 A(j,j-1) = -1 A(j,j) = 2 A(j,j+1) = -1 end do print *, 'Matrix A: ' write(*,1) A 1 format(6i10) end program fin_diff_matrix For the output

Output of a C string program

半腔热情 提交于 2019-11-28 14:11:10
#include<stdio.h> int main() { char s[2]="a"; s[1]='b';s[2]='c';s[3]='d';s[5]='e'; printf("%s $%c$",s,s[4]); return 0; } 1.When I run this program in C (gcc-4.7.2) I expected Runtime Error because of the missing Null Character ('\0'). 2.If still the program compiles and executes successfully ,since s[4] has not been initialised,I expected some garbage value at that place..but here also I was wrong. The output of the above program is: abcde $$ There is no character between the two $(dollor) which indicates printf skips s[4]. here is a ideone link for the same: http://ideone.com/UUQxb2 Explain

Execute any bash command, get the results of stdout/stderr immediatly and use stdin

寵の児 提交于 2019-11-28 12:27:38
问题 I would like to execute any bash command. I found Command::new but I'm unable to execute "complex" commands such as ls ; sleep 1; ls . Moreover, even if I put this in a bash script, and execute it, I will only have the result at the end of the script (as it is explain in the process doc). I would like to get the result as soon as the command prints it (and to be able to read input as well) the same way we can do it in bash. 回答1: Command::new is indeed the way to go, but it is meant to execute

Fortran formated output for floating point numbers

与世无争的帅哥 提交于 2019-11-28 11:53:28
问题 Is there a way in Fortran to write float numbers as 17,3 and not 17.3 , changing the dot to a comma? I have some large data sets wirtten to a .csv by a subroutine, and i want to do some Excel on it. The german version of Excel uses . as a seperator in floating point numbers. I know i can use the import feature to handle it, or use Nodepad++ to search and replace . with , . But i do generate lots of these files, and the subroutine will be used by others, so an Excel ready file would be nice.

why the string is getting altered after strcat()?

痴心易碎 提交于 2019-11-28 11:47:52
问题 this is the source code int main() { char str[]="dance"; char str1[]="hello"; char str2[]="abcd"; strcat(str1,str2); printf("%s",str); } output- bcd why str is changed after strcat(str1,str2); 回答1: str1 has not enough space to concatenate the string str2 . This invokes undefined behavior . You may get anything. Either expected or unexpected result. Now try this: #include <stdio.h> #include <string.h> int main(void) { char str[]="dance"; char str1[10]="hello"; char str2[]="abcd"; strcat(str1
