Hi, I've recently switched from a linux distribution to another (F27). During the last 2 years i used a script to build DMD, unfortunately i forgot to include it in my backup. Initially i thought "No problem, there's the instructions in the wiki, it's more or less about calling make with a couple of option". In theory only...

make -fposix.mak gives me

All required tools are setup. I do not set AUTOBOOTSTRAP=1 since dmd 2.077 is setup.

I needed gcc-c++... I don't know why but since "which g++" gave a valid file name i thought it was enough.

What's the difference ?

I don't know how Fedora works but you need a C++ compiler [1]. It seems like "gcc-c++" is the name of the "g++" package in Fedora.

That's strange because as said i had g++ / c++ but DMD compiles only once gcc-c++ setup. Anyway, working now.

It should be possible to get which package the "g++" file belongs to [1].

According to Google Translate, this means your C++ compiler doesn't support 64-bit mode.  Not sure why, since the Makefile is only compiling in 64-bit after checking that's what your kernel is, with uname -m.
