From abd4192b07c5a7dbb4b13a532d0643982b42526f Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Thu, 27 Mar 2025 11:53:03 +0000 Subject: [PATCH] detect-compiler: detect clang even if it found CUDA In my setup, clang finds `/usr/local/cuda` and hence the output of `clang -v` ends with this line: Found CUDA installation: /usr/local/cuda, version This confuses the `detect-compiler` script because it matches _all_ lines that contain the needle "version" surrounded by spaces. As a consequence, the `get_family` function returns two lines: "Ubuntu clang" and above-mentioned line, which the `case` statement does not handle well and hence reports "unknown compiler family" instead of the expected set of "clang14", "clang13", ..., "clang1" output. Let's unconfuse the script by letting it parse the first matching line and ignore the rest.
