[Message part 1 (text/plain, inline)]

I installed libgccjit from homebrew on the latest MacOS.

Using the option --with-native-compilation to build Emacs, during the configure phase I got:


checking libgccjit.h usability... yes
checking libgccjit.h presence... yes
checking for libgccjit.h... yes
configure: error: Installed libgccjit has failed passing the smoke test.

“usabilty” yes, but then “failed” some test, look contradictory.
What is the “smoke test”? There is no hint in any of the docs coming with Emacs.

The complete error message in the configure file is this:

"Installed libgccjit has failed passing the smoke test.
You can verify it yourself compiling:
<https://gcc.gnu.org/onlinedocs/jit/intro/tutorial01.html>.
Please report the issue to your distribution if libgccjit was installed through
that.
Here instructions on how to compile and install libgccjit from source:
<https://gcc.gnu.org/wiki/JIT>."

(I haven't yet tried building --with-native-compilation so I don't know
if the configure output shows the complete message.)

Thanks for your reply. However, I could not find anything helpful on the webpages you gave me. So I followed this:

In any case, I find it contradictory that the compilation  of Emacs reports on the one hand "checking libgccjit.h usability… yes,” and on the other hand "Installed libgccjit has failed passing the smoke test."
