Load error on Windows and Julia 1.2

Hi,

I am getting the following load error with Julia 1.2 and Windows:

Hi @mohamed82008, the build script will read Project.toml under the Libtask package dir to obtain the current version, then download the corresponding dynamic library.

If this process fails (no Project.toml found, or no version setting in that file), it will assume the package dir a git repository, and use a git command to find the latest tag the use it as the version number.

According to the error info you posted, it seems that it failed to find the current version from the Project.toml file, and the package dir is not a git repo either.

Generally, there must be a Project.toml file under the package dir, this is mine:

[000]zhuoq@ZHUOQL-XPS:/c/Users/zhuoq/.julia/packages/Libtask/RjRkK$ pwd
/c/Users/zhuoq/.julia/packages/Libtask/RjRkK
[000]zhuoq@ZHUOQL-XPS:/c/Users/zhuoq/.julia/packages/Libtask/RjRkK$ ls -a
.  ..  .gitignore  .travis.yml  appveyor.yml  deps  LICENSE  Project.toml  README.md  src  test
[000]zhuoq@ZHUOQL-XPS:/c/Users/zhuoq/.julia/packages/Libtask/RjRkK$ grep version Project.toml
version = "0.3.1"
[000]zhuoq@ZHUOQL-XPS:/c/Users/zhuoq/.julia/packages/Libtask/RjRkK$

Do you have this file in the package dir? I didn't get an idea of why this file is missing for now, will dig deeper.

[mohamed82008]

The file is there:

user@DESKTOP-32VUB91 MINGW64 ~/.julia/packages/Libtask/RjRkK
$ ls
appveyor.yml  deps/  LICENSE  Project.toml  README.md  src/  test/

user@DESKTOP-32VUB91 MINGW64 ~/.julia/packages/Libtask/RjRkK
$ grep version Project.toml
version = "0.3.1"

Oh, I know, it's an error while downloading files from github using CURL.

Here we try to download https://github.com/TuringLang/Libtask.jl/releases/download/v0.3.1/build_LibtaskDylib.v0.3.1.jl, then an error occurred:

Error: Download failed: curl: (35) schannel: next InitializeSecurityContext failed: Unknown error (0x80092012) - The revocation function was unable to check revocation for the certificate.

I did some search on the internet, it seems that you are using a proxy? That may interfere with the CURL's SSL connection.

see: https://curl.haxx.se/mail/lib-2016-03/0202.html

[mohamed82008]

I am not using a proxy no.

[KDr2]

Hmm, could you:

1. in the Julia REPL, type ";" to enter the shell mode
2. run the command curl -L https://github.com/TuringLang/Libtask.jl/releases/download/v0.3.1/build_LibtaskDylib.v0.3.1.jl

to check if you can download the script successfully?
If there is no error, please try to build Libtask again.

[mohamed82008]

Ok it was unsuccessful because the antivirus thought the server was suspicious. I added 2 urls to exclusions and it worked. Thank you. Do you know why this is an issue in Julia 1.2 but 1.1?

[KDr2]

I am not sure of that. I run ; curl --version under Julia 1.1 and 1.2 on my windows box, it shows the same version of CURL was used (and I didn't get the build error on both Julia versions either).

I think all Julia installations use the same CURL in common case, so I have no idea of the difference. Maybe the antivirus treats them differently?

[mohamed82008]

Oh well, I am getting the same version too. I will close the issue for now. If someone else reports the same issue, we can look into it again. Thanks for your help.
