I'm not asking anyone to hold my hand and explain it to me though, I'll do more research tomorrow. I don't mean to sound like a petulant ingrate when I say this, but when I read the aforementioned "Geany manual" text I still don't understand it, I need an example of why the substitutions are necessary I think etc. I assume when I initiated the install shell it populated fbc in $PATH. I think I'll have to look for a more elaboratory tutorial on $PATH, I just read that it's an "environmental" variable (not sure what environmental means, like operating system variable?) which stores directories for you to use, but as to the specifics on how I'm still vague. I have to apologise for my fundamental ineptitude with Linux making a bad situation worse. I know that this is a freebasic forum, not a linux forum, but I have to ask: I thought everything was a file in linux, so what is an 'executable'? Like a shell? Just click the link in the quote-box (the text "Geany manual"). (The name stands for ``text file busy''.Tone wrote:This is embarrassing, but is there an even more dumbed-down explanation than. Often using aĭebugger to run a program is considered having it open for writing and Write to a file that is currently being executed. Sysdeps/mach/hurd/bits/errno.h:62: ETXTBSY = 0x4000001a, /* Text file busy */Īnd a manual hit in manual/errno.texi: Macro int 26, Text file busy}Īn attempt to execute a file that is currently open for writing, or karel at 12:08 8 While editing using vim, hit Esc and type :sh and Enter, when done hit Ctrl-D and you'll get back to your vim session. Pathname refers to an executable image which is currently being executed and write access was requested.Ī quick grep on 2.30 gives: sysdeps/gnu/errlist.c:299: = N_("Text file busy"), The file is a pure procedure (shared text) file that is being executed and oflag is O_WRONLY or O_RDWR. Although you can remap most keybindings to suit your taste, Geany cannot currently fully emulate Emacs or Vim, nor is it currently a goal of the core project developers to make it do so. The reason it does not fail is that when you unlink and re-write the file, it creates a new inode, and keeps a temporary dangling inode for the running executable file.īut if you just write without unlink, then it tries to write to the same protected inode as the running executable. As its default, Geany uses the standard GTK+ keybindings that most desktop users are familiar with. openat(AT_FDCWD, "sleep.out", O_RDWR|O_CREAT|O_TRUNC, 0666) = 3 sleep.c |& grep sleep.outĬontains: unlink("sleep.out") = 0 That does not generate an error, even though the second gcc call is writing to sleep.out.Ī quick strace shows that GCC first unlinks before writing: strace -f gcc -std=c99 -o sleep.out. This explains why it works for certain programs but not others. Then compile and run analogously to the above, and those asserts pass. The error does not happen if you unlink firstĪssert(open("sleep.out", O_WRONLY|O_CREAT) != -1) and assign Send selection to terminal to a. Tested on Ubuntu 18.04, Linux kernel 4.15.0. To send R commands from the editor to the integrated Virtual Terminal Emulator (VTE), you need to download Geany > 0.19. Which contains: openat(AT_FDCWD, "sleep.out", O_WRONLY) = -1 ETXTBSY (Text file busy) Makes Bash output: -bash: sleep.out: Text file busyįor a more complex application, you can also observe it with strace: strace. So we deduce that the message is hardcoded in glibc itself. sleep.cīusy.out passes the asserts, and perror outputs: Text file busy Int ret = open("sleep.out", O_WRONLY|O_TRUNC) Ĭompile and run: gcc -std=c99 -o sleep.out. I recommend understanding the underlying API to better see what is going on. Note here instead of geany gedit is used you can replacce it with geany if you want to be, rest of the code will work as desired. (According to the documentation, F5 executes the current file in a terminal emulation. This word is passed as an argument to these. Minimal runnable C POSIX reproduction example Im trying to run the sample script Ive written (please see screenshot 1) by pressing F5 - normally, this should open the terminal and execute the code. Geanydoc is plugin for Geany IDE that allow execute specified commands on the current word at the cursor position.
