Running on OpenSUSE 13.2

[alexeycalinovski]

I have successfully ran a console and ASP.NET 5 app using DNX coreclr on Ubuntu, but I am not able to do so on Opensuse 13.2 x64. I followed this tutorial : http://dotnet.github.io/docs/getting-started/installing/installing-core-linux.html .
I am trying to run a simple hello world as in the tutorial but the commands dnu and dnx do not do anything, they run and exit immediately.
The output of dnvm list :

Active Version              Runtime Architecture OperatingSystem Alias
------ -------              ------- ------------ --------------- -----
     1.0.0-rc1-final      coreclr x64          linux
     1.0.0-rc1-final      mono                 linux/osx       default
*    1.0.0-rc1-update1    coreclr x64          linux
     1.0.0-rc2-16237      coreclr x64          linux

How can I get this to work on OpenSUSE 13.2? The final goal is to run a ASP.NET 5 application.

export DNX_TRACE=1 to see what is happening. Most likely you don't have libicu or the one you have is no the one coreclr was linked against.

One thing to add - we have not tested dnx on SuSe and SuSe is not officially supported so if things work it's great but they may not work.

[alexeycalinovski]

I understand that, but I hope it will work .. or I can contribute by finding why it doesn't :) . Anyway, the export helped in getting this :

Loaded module: dnx.coreclr.so
Found export: CallApplicationMain

Unhandled Exception:
     Cannot print exception string because Exception.ToString() failed.
 Aborted

libicu-devel-51.2-6.1.2.x86_64

The error you get you are missing libicu. See aspnet/dnx#3059 for more details.

I got over that part by using your suggestion. I now have this other error, when I issue dnu restore:

I followed #1502 but still the error remains.

Also, I intended to add more nuget feeds but I can't find NuGet.config file, as described here and because of #3550.

[moozzyk]

Are you sure you have libcurl and libssl installed (as per https://docs.asp.net/en/latest/getting-started/installing-on-linux.html)?
For restore you can use the -s <FEED> parameter to use a specific feed. You can use multiple -s if you want to restore from multiple feeds. I guess you could just create a NuGet.config file if it is missing.
You can also use dnu feeds list to see what the effective feeds for you project are.

curl --version
curl 7.42.1 (x86_64-suse-linux-gnu) libcurl/7.42.1 OpenSSL/1.0.1k zlib/1.2.8 libidn/1.31 libssh2/1.5.0

ls /usr/lib64/libssl*
/usr/lib64/libssl3.so  /usr/lib64/libssl.so  /usr/lib64/libssl.so.0.9.8

Issue #2995 also suggests the problem is from incorrect version of libcurl .

ldd ~/.dnx/runtimes/dnx-coreclr-linux-x64.1.0.0-beta8/bin/System.Net.Http.Native.so
 linux-vdso.so.1 (0x00007ffce72b5000)
 libcurl-gnutls.so.4 => not found
 libstdc++.so.6 => /usr/lib64/libstdc++.so.6 (0x00007f1933fba000)
 libm.so.6 => /lib64/libm.so.6 (0x00007f1933cb7000)
 libgcc_s.so.1 => /lib64/libgcc_s.so.1 (0x00007f1933aa0000)
 libc.so.6 => /lib64/libc.so.6 (0x00007f19336f1000)
 /lib64/ld-linux-x86-64.so.2 (0x00007f19344e7000)

So it seems I am missing libcurl-gnutls.so.4, creating a sym link allows dnu (/usr/lib64/libcurl-gnutls.so.4 -> libcurl.so.4.3.0) to run without error, but I don't know to what extent. So I'll try building libcurl with gnutls support.

Building curl with gnutls works fine.
