Whenever it comes to the step of configuring openPA, the configure process fails, and the building process terminates right there. I have been looking at the config.log in openPA, and have found some errors, but I cannot make sense of these errors. Pardon me, I am unable to provide a direct finger to these problems, and would have to refer to the attached config.log from the openPA folder. Some info which might help. I am attempting to build this on a Windows machine via Cygwin64. Source location: Downloads Folder Build location: Documents Folder Installation Folder: C drive General description of errors mentioned: i) Unrecognized command line options ‘-V’ and ‘-qinversion’ ii) Configure: gcc –DNDEBUG –DNVALGRIND --> It couldn’t find the directories specified iii) Error: C compiler cannot create executables Thanks, Thad _______________________________________________ discuss mailing list [email protected]<mailto:[email protected]> To manage subscription options or unsubscribe: https://lists.mpich.org/mailman/listinfo/discuss
