Hi,

I am very sorry - I feel I should know this, or be able to work it out, but is there a way of setting the flags to the C compiler and the linker, for the Numpy build, on Windows?

I'm trying to set the flags for a build with Windows mingw-w64 - but I believe Numpy is ignoring $env:LDFLAGS, $env:CFLAGS and $env:OPT - and I can't see any way of setting these options from the command line. Am I missing something?

Cheers,

Matthew

I don't know how you are using env, but variables set that way are local to the shell in which they are set. In PS that is every separate shell invocation. Chuck
