Summary: Support optional use of the C++ compiler in AC_PROG_CXX (and similarly for other languages) Project: Autoconf Submitted by: zackw Submitted on: Sun 06 Dec 2020 10:25:57 PM UTC Category: None Priority: 5 - Normal Severity: 1 - Wish Status: None Privacy: Public Assigned to: None Originator Email: Open/Closed: Open Discussion Lock: Any Operating System: None _______________________________________________________ Details: Bug #110294 reports a regression in autoconf 2.70 on the configure script for a program that has some C and some C++ code, but use of the C++ code is optional. The code that broke attempts to do most of what AC_PROG_CXX does, but *not* abort the configure script when a C++ compiler is not found. Instead, output variables would be set so that compilation of C++ code is disabled. We do not want to support this particular kludge, as it would pin down the guts of AC_PROG_CXX too much, but we _should_ support optional use of the $LANG compiler (for all values of $LANG). Perhaps with an additional argument to AC_PROG_CC, AC_PROG_CXX, etc, marking usage optional. See also bug #110286. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/support/?110394> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
