Add: xdebug.remote_autostart=On xdebug.remote_log="c:\temp

问题 I have 3 processes which need to be synchronized. Process one does something then wakes process two and sleeps, which does something then wakes process three and sleeps, which does something and wakes process one and sleeps.

I use sem_post to trigger (wake) each process, and sem_timedwait() to wait for the trigger. This all works successfully for

问题 I can't seem to find a compiler/plugin for mono. Does one exist? 回答1: Go here and download fsharp.zip Unzip it and open the created folder Open the terminal and run ./install-mono.sh as root (On some systems, it is necessary to convert the newline characters in that script from CRLF to LF) This will give you the basic functionality which means you will be able to run "mono fsi.exe" and compiled F# apps as "mono myApp.exe". Usefull tips: It makes sense to create scripts for the compiler and F#
