Build fails on Fedora 20

[russel]

I am trying to build LDC from Git master/HEAD. I am getting the following error. I am guessing the is some form of user error?

[enclosed the output in a code block for readability]

It's not necessarily a pebcak error, but first things first: Are you working from a clean Git clone/build directory?

Also, could you please paste the linking command line (make VERBOSE=1)? It seems like a bunch of functions from dmd2/root/port.c are missing.

Just getting more data on Fedora 20. The Git repository is "clean" as far as I am aware. Indeed the build is entirely successful on my Debian Unstable.

Can't confirm. I did a clean install of Fedora 20 Desktop 64bit and installed the following packages:

yum install gcc gcc-c++ llvm llvm-devel llvm-static git cmake libconfig libconfig-devel zlib zlib-devel

Then I cloned the repository git clone --recurse-submodule https://github.com/ldc-developers/ldc.git, changed in my build directory and issued cmake ../ldc and make. No linker error.

From the error message it looks like dmd2/root/port.c is not compiled. I propose you should clean your build folder and re-run cmake.

Time has left this report behind, so it seems right to close it.
