[ad_1] Just download and install the free and prebuilt Codesourcery/Mentor Arm cross-compiler and toolchain from here. 2 [ad_2] solved How to compile the cross-compiler arm-linux-eabi-gcc? [closed]
[ad_1] If you want to do it in pure bash, use the following script: #!/bin/bash while read line; do line=( ${line//[:]/ } ) for i in “${!line[@]}”; do [ ! -z “${line[$i]##*[!0-9]*}” ] && printf “integer” || printf “string” [ “$i” -ne $(( ${#line[@]} – 1)) ] && printf “:” || echo done done < … Read more
[ad_1] listenfd = lacz_tcp(wiadomosc->port); From what I can tell, the port has not been initialized before you call bind. Log the port to be sure that the server is listening on the correct port. 2 [ad_2] solved Connection refused – tcp socket in linux [closed]
[ad_1] Note that “reachability” on IP networks is kind of tricky to test for. It’s perfectly possible that a server machine is running any number of real services (www, ftp, whatever), but has been configured not to reply to pings since some people do that. If possible, it’s better to just connect like the real … Read more
[ad_1] You could simply do this through awk, $ awk -F[,-] ‘{var=$1″-“$2; for (i=3;i<=NF;i++){print var”-“$i}}’ file 86-22-63385835 86-22-63385836 86-22-63385933 86-0577-88609993 86-0577-88835386 86-21-58947602 86-21-58947603 0086-755-33186858 0086-755-33186862 0086-755-33186859 2 [ad_2] solved How to process this text [closed]
[ad_1] You are most likely running into the NL/CR issue. Instead of if (a[i]==””) Use something like: if (isEmptyLine(a[i])) where bool isEmptyLine(std::string const& s) { for ( auto c : s ) { if ( !std::isspace(c) ) return false; } return true; } You can also convert the file into a file with UNIX style … Read more
[ad_1] You should read time(7). Be aware that even written in assembler, your program will be rescheduled at arbitrary moments (perhaps a context switch every millisecond; look also into /proc/interrupts and see proc(5)). Then any hardware timer is meaningless. Even using the RDTSC x86-64 machine instruction to read the hardware timestamp counter is useless (since … Read more
[ad_1] The following awk script should solve your probelm provided you manually add the School heading yourself or if that remains same add it as BEGIN { printf “School” } in below example. $ cat input_file Mark,Texas High, Dallas, k-5 Steve,SA high,Antonio,k-5 Adam,Plano tech,k-5 $ awk -F, ‘BEGIN { sep = “”} { printf(“%s%s”, sep, … Read more
[ad_1] This is something I ran into not long ago so trust me on here… Let’s check out this little guy below: if(condition == true) In a way you’re already answering your question, just not comprehending the syntax. (check it out) using System; using System.IO; namespace StackOverflowQA { class Program { static void Main(string[] args) … Read more
[ad_1] I’m not giving you a working solution but just a hint: The JPEG format consists of different parts, some are required and some are optional. Among those optional parts, some allow to store arbitrary data. If you manage to alter such a part of an existing JPEG image or to add one and put … Read more
[ad_1] My guess without a code example is that you were operating on the buffer or struct you malloc’d with assumptions that its contents would be initialized with certain default values. Malloc doesn’t initialize the memory it hands back, so unless you memset or use some other initialization, the values in that memory could be … Read more
[ad_1] since I don’t have response for my question. I would like to share with you the response for that problem. The acsd service take the port because the socket is not closed and the option SO_REUSEADDR is set [ad_2] solved My linux application port is taken by another service when it’s stopped
[ad_1] Not much unless you’re root. If you are root, services that require files with certain permissions will stop working. sudo is one of those. 3 [ad_2] solved Chmod recursively for /
[ad_1] I want to access my website with my domain name now. Like example.com instead of http://11.22.32.44 According to your description, we can add a A record to register.com. We should do this in the domain name manager web page, map the domian name to this public IP address, in this way, we can access … Read more
