[Windows] Unable to build

[macintoshplus]

1. I have installed the latest version of Rust lang (x64) on Windows 10
2. I have run cargo build on Rymfony folder

This is the result:

X:\>cargo build
   Compiling autocfg v1.0.1
   Compiling unicode-xid v0.2.1
   Compiling cfg-if v0.1.10
   Compiling lazy_static v1.4.0
LLVM ERROR: IO failure on output stream: bad file descriptor
error: could not compile `cfg-if`

To learn more, run the command again with --verbose.

Maybe you are building it on a network drive? If so, there seems to be no workaround yet for this (check rust-lang/rust#54216)

Edit: there actually is a workaround: put the project in a non-network drive in the VM, it should do the trick. It can be cumbersome though if your IDE is on the host and the code is in the VM.

Yes, the project is in shared folder with Virtual Box.

After copy the project, into another drive, I have now this error:

I have follow this documentation to install OpenSSL on my windows System
https://github.com/sfackler/rust-openssl/tree/5948898e54882c0bedd12d87569eb4dbee5bbca7#installing-openssl-110-using-precompiled-binaries

[Pierstoval]

Did you install OpenSSL through vcpkg?

I personally installed it in my dev directory, and have set the envs var as such:

> env | grep SSL
OPENSSL_DIR=C:\dev\vcpkg\packages\openssl_x86-windows-static
OPENSSL_INCLUDE_DIR=C:\dev\vcpkg\packages\openssl_x64-windows-static\include
OPENSSL_LIB_DIR=C:\dev\vcpkg\packages\openssl_x64-windows-static\lib
OPENSSL_NO_VENDOR=1
OPENSSL_STATIC=Yes
SSL_CERT_FILE=C:\dev\vcpkg\packages\openssl_x86-windows\certs\cacert.pem

And in my PATH, I have this (I use Powershell):

> $env:PATH | sed 's/;/\n/g' | grep -i ssl
C:\dev\vcpkg\packages\openssl_x86-windows\tools\openssl
C:\dev\vcpkg\packages\openssl_x86-windows\bin

Thanks @Pierstoval, I can build on Windows.
