How is it possible that you have problems compiling a srpm? You must have changed something. What is even this el6? ;) If you want run dovecot on older el6 maybe try via docker?
I encountered the following issue while compiling Dovecot on a Linux system with the Shenwei architecture in China using RPM: During the build phase, it shows: Copy Code checking whether fd passing works... no configure: error: fd passing is required for Dovecot to work The version of Dovecot I am compiling is 2.3.16, and the version of the GCC tool is 8.5.0. My spec file's build section is as follows: Copy Code %build # required for fdpass.c line 125,190: dereferencing type-punned pointer will break strict-aliasing rules %global _hardened_build 1 export CFLAGS="%{__global_cflags} -fno-strict-aliasing -fstack- reuse=none" export LDFLAGS="-Wl,-z,now -Wl,-z,relro %{?__global_ldflags}" # el6 autoconf too old to regen; use packaged files (#1082384) mkdir -p m4 autoreconf -I . -fiv # required for aarch64 support %configure
