[epScript] Missing libepScriptLib.so

[zuhanit]

It seems there's only libepScriptLib.dll exists but .so and .dylib isn't. Is it intended? I'm using Arch Linux on WSL 2.

OSError: ***/eudplib/epscript/libepScriptLib.so: cannot open shared object file: No such file or directory

You can build your own libepScriptLib.so using CMake and C++ compiler with https://github.com/armoha/eudplib/blob/master/eudplib/epscript/cpp/CMakeLists.txt

Following https://int-i.github.io/cpp/2020-08-09/github-actions-boost/ , https://gist.github.com/NickNaso/0d478f1481686d5bcc868cac06620a60 and other articles, I tried adding github actions for building libepScriptLib.so in armoha/eudplib@26a2134 , but failed with error: /bin/sh: 1: ./lemon2: Exec format error
I guess https://github.com/armoha/eudplib/blob/master/eudplib/epscript/cpp/lemon2 is not linux executable but macOS (OS X) binary? Probably @phu54321 would know. I don't have linux machine to test this so feel free to open PR for github workflow yaml.

uh just compile https://github.com/armoha/eudplib/blob/master/eudplib/epscript/cpp/lemon2.c

gcc lemon2.c -o lemon2

[zuhanit]

I don't know about CMake or C++, anyway I tried to build following commands. But il fails... :(

cd eudplib/epscript/cpp
gcc lemon2.c -o lemon2
mkdir build && cd build
cmake ..
make

Now I remembered, before using MSVC, updating GCC in mingw32 caused build failure so I had to use MinGW-w64 with GCC 6.4.0 to build epScript successfully in 2019.
Maybe GCC or linux version is related here.

[zuhanit]

Finally, I renamed epparser.c to epparser.cpp and add #include <cstring> in parserUtils.cpp and it works to build libepScript.so file. Yes I know it is something like fool approach 🤣

[armoha]

This issue will be superseded once we set up CI/CD for linux and mac in #136
