Error compiling muparser with Rtools/MinGW on Windows

Hi,
I embedded muparser into my R package with Rcpp. It can compile very well with GCC (on my Linux machine) but I encountered lots of warnings and errors when compiling it on Windows using the compiler MinGW in Rtools. Since this is an R package, on Windows I can only embed it with the MinGW in Rtools.
The main warning is: warning: [...] redeclared without dllimport attribute: previous dllimport ignored
And the main error is: error: definition of static data member [...] of dllimport'd class
Do you happen to know any way to fix these? I see there is a line for dllimport and dllexport in the muParserFixes.h but not sure whether these are solutions and how to fix it.
Thank you!

Sorry, can't help you i don't use mingw.

Hi Ingo,
When I changed line 69 to DLL_EXPORT it fixed my case. Hope to help somebody having the same issue as me lol. Thank you so much for such a great library!
beltoforion commented
Thanks for the feedback. I'm trying to figure this one out. If you changed line 69 to MUPARSER_HELPER_DLL_EXPORT you did the same that the -DBUILD_SHARED_LIBS=ON/OFF would do when using cmake. I never used mingw, so this may be a stupid question but does cmake work with mingw? Did you use cmake of did you have to create your own build script?

Hi,
Sorry I haven't worked with C++ long enough, actually I guess I am the one who did stupid things lol. I'm an R user and only learn C++ recently to improve my R packages. I'm a self taught developer and don't even know exactly what is building a C++ library (haven't read to that part yet, but I'll find it now), only follow your instructions to copy the essential files into src folder to use it. When the error occurred and I see that line of comments in file muParserFixes.h I think I may change it since I only use muparser and not building anything, luckily it worked.
In my case, I tried to implement muparser into my R package (because C++ run around 10x faster than R native code so many people are mixing R with C++). The package is developed to advance SIR model simulation used in infectious diseases outbreak modelling such as the COVID-19 pandemic, if you have any interest you can have a look at it here lol. In R, we compile the C++ code with another package called Rcpp, and it basically uses the native compiler on users' computer to compile C++ code. The Rcpp has its own script to compile the C++ code and we do nothing on that part. I checked and figured that the mingw actually use g++ on my windows machine.
More and more people are developing their R package with C++ code and libraries implementation, personally I think muparser will be used more often in the future so I came back to report how I solved this problem, hoping it can help other R users who intend to use muparser (and also who are not very proficient in C++ like me lol). Thank you so much for writing such a nice and powerful library.
