warnings

问题 I am editing a quick sort code so that the values of low, high, and middle point to an array element instead of integers. This is my code: #include <stdio.h> #define N 10 void quicksort(int a[], int *low, int *high); int split(int a[], int *low, int *high); int main(void) { int a[N], i; printf("Enter %d numbers to be sorted: ", N); for (i=0; i<N; i++) scanf("%d", &a[i]); quicksort(a, &a[0], &a[N-1]); printf("In sorted order: "); for (i=0; i<N; i++) printf("%d ", a[i]); printf("\n"); return 0;

问题 Sometimes my Maven build gives a warning, i.e., the Maven output has a line starting with [WARNING] . (I am not talking about, e.g., warnings in compiled Java code, but, e.g., a warning that an empty jar-file is being created.) In such a situation I want my build to fail. How do I do that? 回答1: This feature was already suggested to Maven team in MNG-5091. Upvote it in their JIRA and let's wait (this is what I did) :) 来源： https://stackoverflow.com/questions/14495014/how-to-make-maven-build

问题 I'm trying to compile zlib from the command line, and I'm getting this message when using -Wall -Wextra -Wconversion (full cross-compile script is below): Compiler error reporting is too harsh for ./configure (perhaps remove -Werror ). Here's the configure test that's generating the line: cat > $test.c << EOF int foo() { return 0; } EOF echo "Checking for obsessive-compulsive compiler options..." >> configure.log if try $CC -c $CFLAGS $test.c; then : else echo "Compiler error reporting is too

问题 In my application, faces messages are not rendered on UI, not sure what is exactly causing this issue. In the server log I see this: WARNING: FacesMessage(s) have been enqueued, but may not have been displayed. What is the reason for such kind of situations? 回答1: Make sure that you have placed <h:message for="..."> or <h:messages> tag in your page, see also JSF 2 message and messages example 回答2: Another reason why a error message is not displayed could be, that the error occurs in the RENDER

问题 I downloaded the new VS 2017 yesterday and it is working fine, except that I am getting this warning on every line where I call the static method Frame.ReadCsv from the Deedle package: FS10001 This method is not intended for use from F# Calls to other static methods Frame.X do not generate the same warning. Example - this line of code generates the warning: let msft = Frame.ReadCsv(Config.tsDir + "MSFT.csv", hasHeaders=true, inferTypes=true) Intellisense recognizes the method and provides the

问题 C99 introduced the concept of designated intializers for structs. So for example, given: typedef struct { int c; char a; float b; } X; I could initialize like: X foo = {.a = '\1', .b = 2.0F, .c = 4}; and calling: printf("c = %d\na = %hhu\nb = %f", foo.c, foo.a, foo.b); would output: c = 4 a = 1 b = 2.000000 As mentioned here this has the "surprising behavior" of assigning to c then a then b , independent of the order of my designated initializers. This becomes a real issue if I have functions

问题 I try to write a site with CodeIgniter but I've a problem with PHP. I'm sure that it's so simple and can't be wrong.
