[Freedom Studio] configure: error: C compiler cannot create executables

Archive General

I have downloaded FreedomStudio-2020-06-3-win64 package and used Create a new Freedom E SDK Software Project by SiFive tools to create a welcome-example for my HiFive1 Rev B. I got some errors when building this project. Can anyone help me solve it.

Below are my build log from Console and config.log file in bsp/build/debug

I believe this is a PATH issue. I installed the same version of Freedom Studio on my E: drive and used the same workspace name and compared the config logs. My test worked fine, correctly resolving the compiler. I noticed in the config.log comparison that you have several path entries that may be interfering with Freedom Studio. Can you try running Freedom Studio with an empty PATH and see if you can create the project? You can do this in a command shell:

>echo %PATH%                                 (see current path)
(lots of path stuff...)
>set PATH=                                   (clear PATH)
>echo %PATH%                                 (verify it is clear)
%PATH%
>FreedomStudio.exe                           (start FS with no inherited PATH)

If you can create the project using this method, then something on your path is definitely interfering. You can investigate that, or create a wrapper batch file to start Freedom Studio with a reduced, or empty PATH).

Let me know how this works for you.
