Subject: gnu autoconf AC_CANONICAL_BUILD returns linux-gnu build_os on Alpine Linux 3.10.3
Date: Mon, 30 Dec 2019 14:24:56 +0300 [thread overview]
Message-ID: <1504261577705096@sas1-0ef7a84b6a92.qloud-c.yandex.net> (raw)
Hello,
gnu autoconf AC_CANONICAL_BUILD returns linux-gnu build_os variable on Alpine Linux 3.10.3.
Here is a snippet from the configure.ac file which I tested in docker alpine:3.10.3
----------------
AC_CANONICAL_BUILD
AC_MSG_NOTICE([build_os=$build_os])
----------------
Output:
----------------
checking build system type... x86_64-pc-linux-gnu
configure: build_os=linux-gnu
----------------
The same code on Alpine 3.8.4 (docker alpine:3.8 ) returns:
----------------
checking build system type... x86_64-pc-linux-musl
configure: build_os=linux-musl
----------------
Is it expected that build_os is detected as linux-gnu instead of linux-musl on Alpine 3.0.3?
Thanks,
Alexander.

return 0;
