Error while building MediaConch_SourceCode

[XMegamanX]

Hello !

I have a problem while buidling MediaConch via GNU CLI source code. Here a snapshot of my terminal :

Problem while compiling MediaConch (CLI)

I have tried to add -ldl to the Makefile of MediaConch but I have the same error. I already have libdl.so in /usr/mib/x86_64-linux-gnu/

Thank you for the help :)

On which OS/Version ?

Try to add these LDFLAGS to the command line: LDFLAGS="-Wl,--no-as-needed -ldl" ./CLI_Compile.sh

[XMegamanX]

Oups sorry. The building is done on a Ubuntu 16.04 Thank you. I will try your solution :).

[XMegamanX]

Thank you, your tip made it ! What --no-as-needed stands for ?

[g-maxime]

@XMegamanX "--as-needed" was enabled by default on Ubuntu 14.04, causing problem with some libraries (like -ldl, -lssl)

"--as-needed" check if the symbol is really used before do the linking, for avoid unneeded runtime dependencies.

If the bug isn't fixed in Ubuntu 18.04, I will look for a workaround.
