Looks either 5.5.21 or Intel compiler specific problem. This is what I get with 5.5.23 and gcc: [openxs@chief mysql-5.5-work]$ cmake \ > -DCMAKE_C_FLAGS="-O3" \ > -DCMAKE_CXX_FLAGS="-O3" -- MySQL 5.5.23 -- C warning options: -Wall -Wextra -Wunused -Wwrite-strings -Wno-strict-aliasing -Werror -Wdeclaration-after-statement -- C++ warning options: -Wall -Wextra -Wunused -Wwrite-strings -Wno-strict-aliasing -Werror -Wno-unused-parameter -Woverloaded-virtual gcc: --pipe: No such file or directory -- Configuring done -- Generating done -- Build files have been written to: /home/openxs/bzr/mysql-5.5-work [openxs@chief mysql-5.5-work]$ cat sql/CMakeFiles/mysqld.dir/flags.make # CMAKE generated file: DO NOT EDIT! # Generated by "Unix Makefiles" Generator, CMake Version 2.8 # compile CXX with /usr/bin/gcc CXX_FLAGS = -O3 -fPIC -Wall -Wno-unused-parameter -fno-implicit-templates -fno-exceptions -fno-rtti -Wall -Wextra -Wunused -Wwrite-strings -Wno-strict-aliasing -Werror -Wno-unused-parameter -Woverloaded-virtual -g -DENABLED_DEBUG_SYNC -DSAFE_MUTEX -I/home/openxs/bzr/mysql-5.5-work/include -I/home/openxs/bzr/mysql-5.5-work/sql -I/home/openxs/bzr/mysql-5.5-work/regex -I/home/openxs/bzr/mysql-5.5-work/extra/yassl/include -I/home/openxs/bzr/mysql-5.5-work/extra/yassl/taocrypt/include -DHAVE_YASSL -DYASSL_PURE_C -DYASSL_PREFIX -DHAVE_OPENSSL -DYASSL_THREAD_SAFE CXX_DEFINES = -Dmysqld_EXPORTS -DHAVE_CONFIG_H -DMYSQL_SERVER -DHAVE_EVENT_SCHEDULER

And what I get with 5.5.21 and GCC: cmake \ -DCMAKE_C_FLAGS="-O3" \ -DCMAKE_CXX_FLAGS="-O3" cat sql/CMakeFiles/mysqld.dir/flags.make we see the flags: ---- # compile CXX with /usr/bin/c++ CXX_FLAGS = -O3 -Wall -Wno-unused-parameter -fno-implicit-templates -fno-exceptions -fno-rtti -O2 -g -DDBUG_OFF -I/root/src/mysql-5.5.21/include -I/root/src/mysql-5.5.21/sql -I/root/src/mysql-5.5.21/regex CXX_DEFINES = -Dmysqld_EXPORTS -DHAVE_RESPONSE_TIME_DISTRIBUTION -DHAVE_CONFIG_H -DMYSQL_SERVER -DHAVE_EVENT_SCHEDULER ----------------------------------------------------------- 5.5.21 and ICC: cmake \ -DCMAKE_C_COMPILER=/opt/intel/bin/icc \ -DCMAKE_CXX_COMPILER=/opt/intel/bin/icpc \ -DCMAKE_C_FLAGS="-O3" \ -DCMAKE_CXX_FLAGS="-O3" cat /root/src/mysql-5.5.21/sql/CMakeFiles/mysqld.dir/flags.make we see the flags: --- # compile CXX with /opt/intel/bin/icpc CXX_FLAGS = -O3 -O2 -g -DDBUG_OFF -I/root/src/mysql-5.5.21/include -I/root/src/mysql-5.5.21/sql -I/root/src/mysql-5.5.21/regex CXX_DEFINES = -Dmysqld_EXPORTS -DHAVE_CONFIG_H -DMYSQL_SERVER -DHAVE_EVENT_SCHEDULER ----------------------------------------------------------- A you can see the same result with -O3 and -O2 in one string. It makes impossible to set -O3 optimization..

Tried on Mac OS X this time: ... macbook-pro:mysql-5.5-work openxs$ cat sql/CMakeFiles/mysqld.dir/flags.make # CMAKE generated file: DO NOT EDIT! # Generated by "Unix Makefiles" Generator, CMake Version 2.8 # compile CXX with /usr/bin/gcc CXX_FLAGS = -O3 -Wall -Wno-unused-parameter -fno-implicit-templates -fno-exceptions -fno-rtti -I/Users/openxs/bzr2/mysql-5.5-work/include -I/Users/openxs/bzr2/mysql-5.5-work/sql -I/Users/openxs/bzr2/mysql-5.5-work/regex CXX_DEFINES = -Dmysqld_EXPORTS -DDBUG_OFF -DHAVE_CONFIG_H -DMYSQL_SERVER -DHAVE_EVENT_SCHEDULER macbook-pro:mysql-5.5-work openxs$ cmake --version cmake version 2.8.1 I wonder what version of cmake do you use?

The latest cmake version 2.8.7 from http://www.cmake.org

I was finally able to repeat this on 64-bit FC14 using cmake 2.8.4: [openxs@chief mysql-5.5-work]$ cat sql/CMakeFiles/mysqld.dir/flags.make # CMAKE generated file: DO NOT EDIT! # Generated by "Unix Makefiles" Generator, CMake Version 2.8 # compile CXX with /usr/bin/c++ CXX_FLAGS = -O3 -Wall -Wno-unused-parameter -fno-implicit-templates -fno-exceptions -fno-rtti -O2 -g -DDBUG_OFF -I/home/openxs/bzr/mysql-5.5-work/include -I/home/openxs/bzr/mysql-5.5-work/sql -I/home/openxs/bzr/mysql-5.5-work/regex CXX_DEFINES = -Dmysqld_EXPORTS -DHAVE_CONFIG_H -DMYSQL_SERVER -DHAVE_EVENT_SCHEDULER [openxs@chief mysql-5.5-work]$ cmake --version cmake version 2.8.4 [openxs@chief mysql-5.5-work]$ fc -l 988 grep -rn '-mp' * 989 grep -rn -- '-mp' * 990 cmake -DCMAKE_C_FLAGS="-O3" -DCMAKE_CXX_FLAGS="-O3" 991 cat sql/CMakeFiles/mysqld.dir/flags.make 992 cmake -DCMAKE_C_COMPILER=/opt/intel/bin/icc -DCMAKE_CXX_COMPILER=/opt/intel/bin/icpc -DCMAKE_C_FLAGS="-O3" -DCMAKE_CXX_FLAGS="-O3" 993 cd ../../dbs/5.5 994 bin/mysqld_safe --no-defaults & 995 bin/mysql -uroot test 996 exit 997 cd bzr/mysql-5.5-work/ 998 cmake -DCMAKE_C_FLAGS="-O3" -DCMAKE_CXX_FLAGS="-O3" 999 ls -l CMake* 1000 rm CMakeCache.txt 1001 cmake -DCMAKE_C_FLAGS="-O3" -DCMAKE_CXX_FLAGS="-O3" 1002 cat sql/CMakeFiles/mysqld.dir/flags.make 1003 cmake --version

We believe this was fixed in 8.0.13: Bug#27874068 ADD SUPPORT FOR -DCMAKE_BUILD_TYPE=RELEASE
