We have a project with multiple Fortran sources (~100) where few of them are also preprocessed (.F). We tried to switch on parallel compilation of source files (/MP), but on some machines the compilation fails (repeatable) with the error message (which appears after output of the preprocessed source files in the log file)
ifort: command line error: multiple sources; asm output option must specify dir
Relevant compile command:
/nologo /MP /O2 /I"some_include_folders" /D"some_defines" ... /libs:static /threads /c /Qvec-report0 /names:lowercase /assume:underscore /iface:nomixed_str_len_arg /fp:source /extend_source:132 /fp:source /Qip /O2 /MD /fpe:3 ...
Intel Fortran version:
Intel(R) Visual Fortran Intel(R) 64 Compiler XE for applications running on Intel(R) 64, Version 220.127.116.11 Build 20121008
integrated to VS2010
How can we detect the source of the error? Why it is triggered only on some machines?
