Hello, as said, in yocto we pass in $CC environment, also the --sysroot keyword.

If --sysroot contains the "*icc*" or "*gcc*" in path, the build fails because of wrong autoconf checks.

checking in a case switch for *icc* seems bad to me, I propose to change it with something like
"*icc" so we might exclude when icc is not the compiler.

I know this isn't a strong patch, but maybe we can apply it while writing some better detect code.

The build fails as descripted in the yocto bug
https://bugzilla.yoctoproject.org/show_bug.cgi?id=12703

I signed the contributor agreement, even if such patches shouldn't need any kind of license

Thank you. Yes, we require a signed CA for something this non-trivial.

Victor, I don't know who maintains configure.  If you don't, maybe you know who does.

Maybe this is the same as Issue 28584, about the ${CC} variable rather than “sysroot”. In any case, the patch looks unrelated.

This was the patch I wanted to add, but I picked up a wrong one (a vbox one)

In any case, duplicate of issue28584

icc-find.patch (and a 2nd version) has been uploaded to #28584 also. I unlinked the erroneous upload 'patch'.
