I think you would have to hard code those path options into those configure commands." +Q: When I try to run the tools I get errors like 'cc1' not found or strange + errors from 'as'. + +A: Did you move the toolchain after you built it? I used to do that all of the + time but building under 64-bit OpenSUSE 13.1, I could not longer do that. + When I executed the compiler in the location where it was built, all worked + well.

I have heard reports that building a + Cortect-M4F toolchain then using it with a Cortex-M3 or M4 without floating + point Make.defs caused the path to 'cc1' to be lost. + + Cygwin GCC BUILD NOTES ^^^^^^^^^^^^^^^^^^^^^^ |
