Seems like you don't have curl installed. Please install cur` and then try again.

[llaine]

Hi,

I do have curl installed that the problem ...

[llaine@localhost ~] $ curl --version
curl 7.43.0 (x86_64-redhat-linux-gnu) libcurl/7.43.0 NSS/3.22 Basic ECC zlib/1.2.8 libidn/1.32 libssh2/1.6.0 nghttp2/1.7.1

OS : Fedora 23 x86-64 with kernel 4.4.9-300

[WebFreak001]

You need libcurl: ls /usr/lib | grep curl

[llaine]

Looks like this is already installed too

[llaine@localhost ~] $ ls /usr/lib | grep curl
libcurl.so.4
libcurl.so.4.3.0

[Vild]

Looks like you are missing a symlink for your curl. This should fix it via a hacky fix: sudo ln -s /usr/lib/libcurl.so.4 /usr/lib/libcurl.so

[Vild]

Do you have libcurl-devel installed? This should fix it, without that hacky symlink hack.

[llaine]

I tried your hacky fix, unfortunatly it didn't work

[Vild]

Looks like installing libcurl-devel should fix it.

@Vild installing the missing dependency solved the problem just fine!

But then another error message appear during the compilation, after running

dub build --build=release

src/analysis/lambda_return_check.d(40,29): Error: no property 'line' for type 'const(FunctionLiteralExpression)'
src/analysis/lambda_return_check.d(40,40): Error: no property 'column' for type 'const(FunctionLiteralExpression)'
dmd failed with exit code 1.
Error while compiling Dscanner.
Program exited with code 1

[WebFreak001]

dmd --version?

[llaine]

DMD64 D Compiler v2.071.0

[WebFreak001]

Wait Dscanner? You sure you didn't accidentally switch projects?

[llaine]

Well to be honest I'm trying to build the https://github.com/Pure-D/workspace-d-installer. Whether I tried to compile this one or the other (workspace-d-installer) I get the same issue so ... But I guess it's related no?

[WebFreak001]

Related to https://github.com/Hackerpilot/Dscanner/issues/350, until that is fixed the installer won't work

[WebFreak001]

Hacky Fix: select 1,3 instead of all on installation instead

[llaine]

It worked thank you @WebFreak001

[dAnjou]

The dependency on libcurl-devel should be mentioned in the README.

[Nguyenvandoi]

You need install libcurl3-dev package sudo apt-get install libcurl3-dev or sudo apt-get install libmosquittopp-dev

[WebFreak001]

you certainly don't need to install a full MQTT broker, just libcurl3-dev is enough.

That said this issue doesn't really apply anymore as you don't need dfmt or dscanner anymore
