Segmentation fault when passing internal function as argument

阅读更多关于 Segmentation fault when passing internal function as argument

问题 I have some code that passes an internal function of the main program as an argument to a function: when the function that been passed is eventually called it causes a segmentation fault. This only occurs when I use Windows Subsystem for Linux (I'm using Ubuntu 16 on WSL); running on native Linux or Mac machines this does not occur. A minimal example that crashes: module test1 implicit none contains subroutine x(ff,y) interface real function ff(y) real, intent(in) :: y end function ff end

Valgrind does not work with WSL?

阅读更多关于 Valgrind does not work with WSL?

问题 When I installed WSL for my computer I was very excited to have a more natively supported Linux system rather than using VirtualBox . However I get this error when I try to run it.

How to check if a program is run in Bash on Ubuntu on Windows and not just plain Ubuntu?

阅读更多关于 How to check if a program is run in Bash on Ubuntu on Windows and not just plain Ubuntu?

问题 Pretty straightforward, the usual places to figure out the OS you're on seem to be identical to plain Ubuntu on Ubuntu for Windows. For example uname -a is identical to a native GNU/Linux install and /etc/os-version is identical to a Ubuntu Trusty Tahr install. The only thing I can think of is to check if /mnt/c/Windows exists, but I'm not sure if that's a foolproof idea. 回答1: The following works in bash on Windows 10, macOS, and Linux: #!/bin/bash set -e if grep -qE "(Microsoft|WSL)" /proc

How can a run Windows executable from WSL (Ubuntu) Bash

阅读更多关于 How can a run Windows executable from WSL (Ubuntu) Bash

问题 Along with Windows 10 Anniversary update for summer 2016, came the possibility to run ubuntu binaries inside the new Windows Subsystem for Linux (WSL), a "lightweight" virtualized subsystem. Unfortunately, launching C:\Windows\System32\bash.exe , another bash ELF binary starts a process inside the WSL, from where you cannot escape! You may launch only other ELF binaries. So how can I execute *.exe files from Windows Bash?[1] [1] Question asked also in Microsoft's "official" GH support repo.
