GET Request leads to libmbedtls.dll error (compiling #sslconnection#18)

[jkort]

Julia 1.0.3
HTTP.jl 0.8.2
MbedTLS.jl 0.6.8 -- Please specify versions

Windows Server 2012 R2 (64-bit)

Possibly related to issue #372, but since closed I did not know how to reopen.

Based on closure of #372, I updated HTTP and MbedTLS packages to latest.

I get a similar error to #372:

`ERROR: LoadError: error compiling #sslconnection#18: error compiling Type: could
not load library "C:\Users\jort.julia\packages\MbedTLS\X4xar\deps\usr\bin\libm
bedtls.dll"
The specified procedure could not be found.

I've not managed to create a simple example w/o proprietary company info in it as yet. BUT - here's the strange thing. If I run this program under Julia REPL using:

julia> ARGS =
julia> include("path\to\program.jl")

It works fine. But calling the same Windows commandline that has worked repeatedly prior to this HTTP/MbedTLS update, using:

D:>path\to\julia.exe path\to\program.jl "agr1 string" "arg2 string" etc.

is what throws the error. When I tried to create a stripped down program that still uses a top-level function calling another function that loops through some HTTP GETs, I can get it to work under Windows, so I'm not sure at what level of complexity the problem occurs. The full program is just repeated GETs together w/ some LibPQ interaction w/ a PostgreSQL database.

Since replacing those DLLs had helped before, I tried overwriting them w/ newer copies from LibCURL. First I overwrote libmedtls.dll, and the error shifted to:

`ERROR: LoadError: error compiling #SSLConfig#46: error compiling ca_chain!: erro
r compiling crt_parse: could not load library "C:\Users\jort.julia\packages\Mbe

One last thing - on removing/deleting MbedTLS and then adding the package back in, I notice the build.log file has a warning:

I realize I've not given you a lot to work with here, but I am dead in the water @ the moment, and I'm hoping the error points you to something obvious (to you, not to me).

Sorry, not sure what I did, but I seem to have been mistaken about this working in the REPL. Get that same sslconnection error. Which I guess is better, at least things are consistently broken for me.

I moved everything to Linux, and having no problem. Should've done that a long time ago. I hope you can find a fix for those stuck w/ Windows.

I seem to have a similar problem and a 4 line test code (although it is a combination of AWS and FTPClient to get HTTP problem triggered) bug in AWSS3

Believe I have the same error:
ERROR: LoadError: error compiling #sslconnection#18: error compiling Type: could not load library "C:\Users\hvarnhav.julia\packages\MbedTLS\X4xar\deps\usr\bin\libmbedtls.dll"
The specified procedure could not be found.

I have checked that the dll is in this folder.

Fixed my ensuring the libmbedtls library used by Julia version & MbedTLS.jl version is the same.
