I am trying to create either a dll or a lib from lapack to use in visual studio.
I created a dll with the following lines from a batch file.
gfortran -shared -o lapack.dll -Wl,-Map,lapack.map -Wl,--output-def,lapack.def -Wl,--out-implib,lapack.a BLAS/SRC/*.o SRC/*.o INSTALL/slamch.o INSTALL/dlamch.o
I link against lapack.a in a VS2008 c project. The c code makes calls to dgesv_ and dnrm2_. The debug version works. The release version generates an unhandled memory access exception. Does anybody know anything about this?
I created a static library with these lines.
ar cr lapack.lib BLAS/SRC/*.o SRC/*.o INSTALL/slamch.o INSTALL/dlamch.o
I added these linker dependencies.
I get unresolved externals. The first of which is
1>lapack.lib(iparmq.o) : error LNK2019: unresolved external symbol _logf referenced in function _iparmq_
I assume _logf is in a mingw library. Does anyone know which one?
