<pre class="moz-quote-pre" wrap="">Hello,
I have an issue with cross-compilation of Clang. The distribution I am
using is Gentoo Linux. The issue occurs due to the missing
`clang-tblgen` binary, so the build fails with the message
"/usr/bin/clang-tblgen not found or usable", as that binary is needed
to cross compile clang.
I came across some discussions in [1] and [2], and from what I
researched, the `clang-tblgen` binary is not installed by the clang's
build system.
Additional CMake configuration options added when Clang is cross
compiled on Gentoo Linux can be seen in the ebuild [3].
I am not sure whether it is necessary to manually build the `tblgen`
binary, or is there another way to do this? Could someone point me to
a workaround for this?
Thank you for your help!
Sincerely,
Jakov
