[erlang-questions] Which On Windows

[Michael Scharrer]

Hi Luke,

i think there is a litte issue in the documentation for building erlang on windows, because the VCPATH or else are not cygwin'ish... with make_winpath() or make_upath() or else which you are able to set in the .bash_profile and this don´t work for me in the newest cygwin 64.
It would be great if you can test this later...


Just here the example

## The PATH variable should be Cygwin'ish
VCPATH=
$VISUAL_STUDIO_ROOT/VC/bin/amd64:\
$VISUAL_STUDIO_ROOT/VC/vcpackages:\
$VISUAL_STUDIO_ROOT/Common7/IDE:\
$VISUAL_STUDIO_ROOT/Common7/Tools:\
$SDK/bin/x86



Are you sure, that it uses for a x64 build of erlang the Windows Kit´s for x86 for the tools rc and mt?
Because in the documentation I have a example "The first part of the 64 bit template is identical to the 32 bit one, but there are some environment variable differences:" and mentioned VCPATH with

$SDK/bin/x86



 C:\Program Files (x86)\Windows Kits\8.1\bin\x86\rc.exe
 C:\Program Files (x86)\Windows Kits\8.1\bin\x86\mt.exe

or should it be

 C:\Program Files (x86)\Windows Kits\8.1\bin\x64\rc.exe
 C:\Program Files (x86)\Windows Kits\8.1\bin\x64\mt.exe



Thanks
michael

Right, because that isn't the correct mt.exe command. Something in the
build steps isn't setting the PATH correctly, or you don't have the
tool anywhere -

Your next step could be to search your drive for mt.exe, make a note
of it, and see if the following command adds the correct directory to
your PATH:

eval `./otp_build env_win32 x64`

Thanks,
Luke

Hello together,

may it could help with my following output "where mt" on Windows 10

user_1@REDACTED ~/erlbuild/otp
$ where mt
C:\cygwin64\bin\mt.exe


An then I call mt to test it, which looks like the beam.smp.dll error during compile.

user_1@REDACTED ~/erlbuild/otp
$ mt
usage: mt [-V] [-f device] operation [count]
