Hi, Tried to build dovecot-2.3.4 on Solaris 11 x86 and it fails at configure part. I just went checked and it last version it works on is v2.3.2.1 Version 2.3.2.1 (OK) # ./configure .... checking Linux compatible mremap()... no checking whether shared mmaps get updated by write()s... yes checking whether fd passing works... yes ... Version 2.3.4 (FAIL) .... checking Linux compatible mremap()... no checking whether shared mmaps get updated by write()s... no checking whether fd passing works... no configure: error: fd passing is required for Dovecot to work .... config.log shows: configure:22538: checking whether shared mmaps get updated by write()s configure:22585: gcc -o conftest -std=gnu99 -g -O2 -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=thunk -mindirect-branch=thunk -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2?? conftest.c? >&5 configure:22585: $? = 0 configure:22585: ./conftest ./configure[2026]: eval: line 1: 29183: Memory fault(coredump) .... onfigure:22610: checking whether fd passing works configure:22685: gcc -o conftest -std=gnu99 -g -O2 -fstack-protector-strong -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -mfunction-return=thunk -mindirect-branch=thunk -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I./src/lib ./src/lib/fdpass.c?? conftest.c? >&5 configure:22685: $? = 0 configure:22685: ./conftest ./configure[2026]: eval: line 1: 29206: Memory fault(coredump) ... $ ulimit -a core file size?????????

Try: ./configure --disable-hardening ... Or build with cc. (Sorry, it's too late for me to do another test today.)

I just went checked and it last version it works on is v2.3.2.1does work just fine on my solaris 11 x86 box. configure:22610: checking whether fd passing works configure:22685: gcc -o conftest -std=gnu99 -g -O2 -fstack-protector -U_FORTIFY_SOURCE -D_FORTIFY_SOURCE=2 -Wall -W -Wmissing-prototypes -Wmissing-declarations -Wpointer-arith -Wchar-subscripts -Wformat=2 -Wbad-function-cast -fno-builtin-strftime -Wstrict-aliasing=2 -I./src/lib ./src/lib/fdpass.c conftest.c -lsocket -lnsl -lresolv >&5 configure:22685: $? = 0 configure:22685: ./conftest configure:22685: $? = 0 configure:22708: result: yes What is your Solaris release and which version of gcc you are using? my test system is solaris 11.3 and I have gcc 4.5.2.
