commit 73f23bf121dc728f3e10461da31b52ee6bd3e727 Author: Jim Jagielski <[email protected]> AuthorDate: Thu Jun 11 15:51:19 2026 -0400 Fix bundled-module builds (nss/nspr) with autoconf >= 2.70 on macOS Newer autoconf makes AC_PROG_CC probe for the highest C standard the compiler accepts and append it (e.g. -std=gnu23) to $CC, turning 'clang' into 'clang -std=gnu23'. That value-with-a-space is exported and passed to bundled module configure scripts as an unquoted inline env assignment (CC=$(CC) sh ../configure), so the shell parses -std=gnu23 as a command: /bin/sh: -std=gnu23: command not found CXX avoided this via the existing macos_c11 wrapper; the in-tree build was unaffected since the C dialect is pinned per-module in solenv/inc/*.mk, so the appended flag served no purpose and only broke external configure runs. Strip the autoconf-appended -std= token right after AC_PROG_CC so $CC stays a single bare compiler word. --- main/configure.ac | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/main/configure.ac b/main/configure.ac index ecc51a4cd6..0654f771bd 100644 --- a/main/configure.ac +++ b/main/configure.ac @@ -1749,6 +1749,15 @@ if test "$_os" != "WINNT" -o "$WITH_MINGWIN" = "yes"; then AC_PROG_CC fi +dnl Newer autoconf (>= 2.70) probes for the highest C standard the compiler +dnl accepts and appends it (e.g. -std=gnu23) to $CC.
