https://community.intel.com/t5/Software-Archive/linker/m-p/945656#M18240 I just bought virt fort. My virtual C++ 6.0 service pack 5 had been working. After <BR />installing virtual fortran 6.5a I can no longer link even simple C programs. I can compile to an object file but in linking I get a fatal LNK2001 error (unresolved external symbol ___pfnBkCheck). <BR />Fortran files can still be compiled and linked.

Please send a zip file of your project and description of the problem to us at vf-support@compaq.com I can't think of anything the 6.5A update could do that would affect VC++ programs.<BR /><BR />Steve Fri, 06 Apr 2001 08:25:31 GMT https://community.intel.com/t5/Software-Archive/linker/m-p/945657#M18241 Steven_L_Intel1 2001-04-06T08:25:31Z
