[build2] error when trying to compile build2

[Phillip Shelton]

HI, thanks for the quick answer.

For my first problem, it does not help that I don't want to use the default c:\build2\ location so it did not exist.  As I said, pointing the idir variable in the bat file to the location that I did want to use "fixed" that location.

As to the second issue, thanks for the link to the latest staged code.  I will try that tonight.

That's probably because you haven't unpacked build2-baseutils. For manual bootstrap instructions please start here:

https://urldefense.com/v3/__https://build2.org/build2-toolchain/doc/build2-toolchain-install.xhtml*bootstrap-windows__;Iw!!PwxmruxY!P85QEf9adLo8uiw2epjuw8SetyYKA9TK7g8C63aTu0fr4KlEbtZx_uHpSVRrc_Mokk8BvaE$ 

And then for MinGW continue with:

Yes, there was a missing header inclusion which has been fixed for the next release. If you would like, you can try the latest staged toolchain which includes this fix:

Alternatively, if you want to stick with build2 0.14.0, you can use the (older version of) GCC compiler from the build2-mingw package (you can still use your MinGW GCC for your own development, just the build system will be build with an older version).
