Hello ! I try to create a dynamic library, say toto.dll, using a static library, say libRmath.a. When loading the toto.dll library, an error occurs asking me for the libRmath.a library. The compilation is done as : gcc -shared toto.dll f1.o f2.o f3.o -L/c/tcl/lib -ltclstub86 -L. libRmath.a on Windows, MinGW and gcc 4.5.2 Can soneone tell me what is wrong in my compilation ? Many thanks in advance !
