I would recommend to use LibXC 5.1.3 with the trunk version of CP2K if functionalities of LibXC 5.x are requested. Do you really need LibC 6.0 instead of LibXC 5.x?<br></div><div><br></div><div>I have downloaded and compiled the trunk version of LibXC and I have the .mod file. I have compiled the LibXC master branch with "autoreconf -i && ./configure --prefix=PATH/TO/LIBXC && make && make check && make install" without any additional flags. So, LibXC should provide the Fortran bindings automatically. How are you compiling LibXC? If you are not doing anything different than me, you have to ask the LibXC developers directly.</div><div><br></div><div>Best,</div><div>Frederick<br></div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr"><a rel="nofollow">abde...@gmail.com</a> schrieb am Sonntag, 25.

In the trunk, it has been fixed. That means if you have to stick to CP2K 8.1, you cannot use LibXC 5.x. If you definitely need functionality from LibXC 5.x, download and compile the trunk version (master branch) of LibXC or wait for the next CP2K release.</div><div><br></div><div>Best,</div><div>Frederick<br></div><br><div class="gmail_quote"><div dir="auto" class="gmail_attr"><a rel="nofollow">abde...@gmail.com</a> schrieb am Samstag, 24.
