From: Marc-André Lureau Date: Wed, 24 Sep 2025 12:03:58 +0000 (+0400) Subject: build-sys: require -lrt when no shm_open() in std libs X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=59a4c0973aa1709d764d9479a5abd421a9408982;p=thirdparty%2Fqemu.git build-sys: require -lrt when no shm_open() in std libs Fail during configure time if the shm functions are missing, as required by oslib-posix.c. Note, we could further check the presence of the function in librt. This is a minor cleanup/improvement.
