fatal error: filesystem: No such file or directory #56

Closed alan-cugler closed 1 year ago

Hi I am trying to build libloot (and eventually loot) natively on ubuntu 18.04. I am primarily following this guys guide and have gotten all the dependencies installed.

I ran these commands to get it compiling and I make it past several dependencies before choking. 

$ mkdir build; cd build/
$ cmake .. && make all

The Error is as follows:

Scanning dependencies of target libloot_internals_tests
[ 55%] Building CXX object CMakeFiles/libloot_internals_tests.dir/generated/loot_version.cpp.o
[ 56%] Building CXX object CMakeFiles/libloot_internals_tests.dir/src/api/api.cpp.o

make: *** [all] Error 2

I did attempt to run through the entire repo and replace #include <filesystem> with #include <experimental/filesystem>. This did get past the half a dozen identical errors but eventually culminated in a final scroll fest of errors.

So is there a dependency or modification I need to make? Its been a couple years since I've done C++ code, but I don't mind having to brush up for this to run native.

Do you have https://packages.ubuntu.com/search?keywords=libboost-filesystem-dev installed? I'm guessing that's probably what you need...

You need to compile with C++17 to get std::filesystem.

@apocalyptech I checked and have this library installed.

@Ortham What would explicitly be the command to do so?

I tried to search for commands to explicitly state c++17 but I am falling short. Currently, I found this post kind of wrestling with a similar problem, but adding -lstdc++ to cmake .. && make all made no difference.

I also found this talking about stating in the files what version to use, but I am assuming I shouldnt have to do that since this code is meant to be in c++17.

Did you export CXX="g++-8" CC="gcc-8" before running cmake?

Closing due to lack of response.
