Looks like you compiled the standalone Rmath library with MinGW. You can't expect to mix-and-match compilers and link together a static library built under another compiler. It is possible that this will work if you try linking to Rmath.dll: WIndows' DLLs are fairly portable (although parameter passing conventions do differ, and we know 'double complex' is not portable). I assume you know how to make a VC++ import library from a DLL, which you would need to do. If you compiled standalone Rmath under VC++, you would not have got a .a but a lib, at least by default. You are welcome to try that: it has been done in the past but is not something we support (nor even would want to answer questions about). > ------ Build started: Project: Complex plugin, Configuration: Debug > Win32 ------ > > > > Linking... > > Creating library .\../Debug/complex_plugin.lib and object > .\../Debug/complex_plugin.exp > > libRmath.a(mlutils.o) : warning LNK4217: locally defined symbol __iob > imported in function _REprintf > > libRmath.a(dbeta.o) : error LNK2019: unresolved external symbol _log1p > referenced in function _dbeta > > libRmath.a(qbeta.o) : error LNK2019: unresolved external symbol _log1p > referenced in function _qbeta > > libRmath.a(lbeta.o) : error LNK2019: unresolved external symbol _log1p > referenced in function _lbeta > > libRmath.a(toms708.o) : error LNK2001: unresolved external symbol _log1p > > libRmath.a(qbeta.o) : error LNK2019: unresolved external symbol _expm1 > referenced in function _qbeta > > libRmath.a(mlutils.o) : error LNK2019: unresolved external symbol > ___fpclassify referenced in function _R_pow > > ../Debug/complex_plugin.dll : fatal error LNK1120: 3 unresolved > externals > > > > Build log was saved at "file://c:\starting point\Debug\BuildLog.htm" > > Complex plugin - 7 error(s), 1 warning(s) > > > > > > ---------------------- Done ---------------------- > > > > Build: 0 succeeded, 1 failed, 0 skipped > > > > At first glance, it looks like C:\Rtools\MinGW\lib\libm.a is missing. > After adding it to my project properties, the results are the same.
