Hi All,
Windows 10 anniversary edition comes with support to execute Linux
binaries. I have been trying to use it with one of our projects, but I have
been getting a weird error. Maybe someone can help me?
The target is pretty simple:
set(BASH "C:\\Windows\\System32\\bash.exe")
set(ARGS "--help")
add_custom_target(linux ${BASH} ${ARGS})
If I then build that project in visual studio (with some extra verbosity) I
get:
Target "CustomBuild" in file "C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.CppCommon.targets" from
project "C:\_Working\delegate\build\linux.vcxproj" (target
"_BuildGenerateSourcesAction" depends on it):
Using "CustomBuild" task from assembly "C:\Program Files
(x86)\MSBuild\Microsoft.Cpp\v4.0\V140\Microsoft.Build.CppTasks.Common.dll".

CMake does not need to re-run because
C:\_Working\delegate\build\CMakeFiles\generate.stamp is up-to-date.
C:\Program Files

error MSB6006: "cmd.exe" exited with code -1073740791.
Done executing task "CustomBuild" -- FAILED.

The command line seems correct. If I just copy it to the windows prompt it
works fine:
C:\Users\tmc> C:\Windows\System32\bash.exe --help
GNU bash, version 4.3.11(1)-release-(x86_64-pc-linux-gnu)
Usage: /bin/bash [GNU long option] [option] ...
/bin/bash [GNU long option] [option] script-file ...
GNU long options:
--debug
--debugger
--dump-po-strings
--dump-strings
--help
--init-file
--login
--noediting
--noprofile
--norc
--posix
--rcfile
--restricted
--verbose
--version
Shell options:
-ilrsD or -c command or -O shopt_option (invocation only)
-abefhkmnptuvxBCHP or -o option
Type `/bin/bash -c "help set"' for more information about shell options.
Type `/bin/bash -c help' for more information about shell builtin commands.
Use the `bashbug' command to report bugs.
I also tried to use it from the visual studio "external tools" and it seems
to work. So I am not sure what is going on. Is there a way to debug
custom_targets?
In case anyone tries the example above on a 64 bit machine: You will need
to copy bash.exe from system32 to syswow64 since VS is 32 bits.
