Hi, I would like some assistance in figuring out a compile error in MariaDB 5.5 series (tested on 5.5.25). I'm trying to create a minimal (client only) build of 5.5.25. This is the cmake configure command used: cmake --no-warn-unused-cli -C /var/tmp/portage/dev-db/mariadb-5.5.25/work/mariadb-5.5.25_build/gentoo_common_config.cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_PREFIX=/usr -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/etc/mysql -DINSTALL_BINDIR=bin -DINSTALL_DOCDIR=share/doc/mariadb-5.5.25 -DINSTALL_DOCREADMEDIR=share/doc/mariadb-5.5.25 -DINSTALL_INCLUDEDIR=include/mysql -DINSTALL_INFODIR=share/info -DINSTALL_LIBDIR=lib64/mysql -DINSTALL_MANDIR=share/man -DINSTALL_MYSQLDATADIR=/var/lib/mysql -DINSTALL_MYSQLSHAREDIR=share/mysql -DINSTALL_MYSQLTESTDIR=share/mysql/mysql-test -DINSTALL_PLUGINDIR=lib64/mysql/plugin -DINSTALL_SBINDIR=sbin -DINSTALL_SCRIPTDIR=share/mysql/scripts -DINSTALL_SQLBENCHDIR=share/mysql -DINSTALL_SUPPORTFILESDIR=/usr/share/mysql -DWITH_COMMENT=Gentoo Linux mariadb-5.5.25 -DWITHOUT_UNIT_TESTS=1 -DNOT_FOR_DISTRIBUTION=1 -DDEFAULT_CHARSET=latin1 -DDEFAULT_COLLATION=latin1_swedish_ci -DWITHOUT_SERVER=1 -DWITHOUT_EMBEDDED_SERVER=1 -DENABLED_LOCAL_INFILE=1 -DINSTALL_SQLBENCHDIR= -DWITH_SSL=system -DWITH_ZLIB=system -DWITHOUT_LIBWRAP=1 -DWITHOUT_READLINE=1 -DWITHOUT_ARCHIVE_STORAGE_ENGINE=1 -DWITHOUT_BLACKHOLE_STORAGE_ENGINE=1 -DWITHOUT_CSV_STORAGE_ENGINE=1 -DWITHOUT_FEDERATED_STORAGE_ENGINE=1 -DWITHOUT_HEAP_STORAGE_ENGINE=1 -DWITHOUT_INNOBASE_STORAGE_ENGINE=1 -DWITHOUT_MYISAMMRG_STORAGE_ENGINE=1 -DWITHOUT_MYISAM_STORAGE_ENGINE=1 -DWITHOUT_PARTITION_STORAGE_ENGINE=1 -DWITHOUT_INNOBASE_STORAGE_ENGINE=1 -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_DO_STRIP=OFF -DCMAKE_USER_MAKE_RULES_OVERRIDE=/var/tmp/portage/dev-db/mariadb-5.5.25/work/mariadb-5.5.25_build/gentoo_rules.cmake /var/tmp/portage/dev-db/mariadb-5.5.25/work/mysql gives the following error during build /var/tmp/portage/dev-db/mariadb-5.5.25/work/mysql/mysys/waiting_threads.c:196:21: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘key_WT_RESOURCE_cond’ make[2]: *** [mysys/CMakeFiles/mysys.dir/waiting_threads.c.o] Error 1 However, if i build the full server, I get no error. cmake configure with no error: cmake --no-warn-unused-cli -C /var/tmp/portage/dev-db/mariadb-5.5.25/work/mariadb-5.5.25_build/gentoo_common_config.cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_INSTALL_PREFIX=/usr -DMYSQL_DATADIR=/var/lib/mysql -DSYSCONFDIR=/etc/mysql -DINSTALL_BINDIR=bin -DINSTALL_DOCDIR=share/doc/mariadb-5.5.25 -DINSTALL_DOCREADMEDIR=share/doc/mariadb-5.5.25 -DINSTALL_INCLUDEDIR=include/mysql -DINSTALL_INFODIR=share/info -DINSTALL_LIBDIR=lib64/mysql -DINSTALL_MANDIR=share/man -DINSTALL_MYSQLDATADIR=/var/lib/mysql -DINSTALL_MYSQLSHAREDIR=share/mysql -DINSTALL_MYSQLTESTDIR=share/mysql/mysql-test -DINSTALL_PLUGINDIR=lib64/mysql/plugin -DINSTALL_SBINDIR=sbin -DINSTALL_SCRIPTDIR=share/mysql/scripts -DINSTALL_SQLBENCHDIR=share/mysql -DINSTALL_SUPPORTFILESDIR=/usr/share/mysql -DWITH_COMMENT=Gentoo Linux mariadb-5.5.25 -DWITHOUT_UNIT_TESTS=1 -DNOT_FOR_DISTRIBUTION=1 -DDEFAULT_CHARSET=latin1 -DDEFAULT_COLLATION=latin1_swedish_ci -DENABLED_LOCAL_INFILE=1 -DEXTRA_CHARSETS=all -DMYSQL_USER=mysql -DMYSQL_UNIX_ADDR=/var/run/mysqld/mysqld.sock -DWITHOUT_READLINE=1 -DWITH_ZLIB=system -DWITHOUT_LIBWRAP=1 -DDISABLE_SHARED=OFF -DWITH_debug=OFF -DWITH_DEBUG=OFF -DWITH_Debug=OFF -DWITH_EMBEDDED_SERVER=OFF -DWITH_profiling=ON -DWITH_PROFILING=ON -DWITH_Profiling=ON -DENABLE_DTRACE=OFF -DWITH_SSL=system -DCMAKE_EXE_LINKER_FLAGS=-ljemalloc -DWITH_SAFEMALLOC=OFF -DWITH_ARCHIVE_STORAGE_ENGINE=1 -DWITH_BLACKHOLE_STORAGE_ENGINE=1 -DWITH_CSV_STORAGE_ENGINE=1 -DWITH_HEAP_STORAGE_ENGINE=1 -DWITH_INNOBASE_STORAGE_ENGINE=1 -DWITH_MYISAMMRG_STORAGE_ENGINE=1 -DWITH_MYISAM_STORAGE_ENGINE=1 -DWITH_PARTITION_STORAGE_ENGINE=1 -DWITH_FEDERATED_STORAGE_ENGINE=ON -DWITH_PBXT_STORAGE_ENGINE=OFF -DWITH_OQGRAPH_STORAGE_ENGINE=OFF -DWITH_SPHINX_STORAGE_ENGINE=OFF -DWITH_FEDERATEDX_STORAGE_ENGINE=ON -DCMAKE_BUILD_TYPE=RelWithDebInfo -DCMAKE_INSTALL_DO_STRIP=OFF -DCMAKE_USER_MAKE_RULES_OVERRIDE=/var/tmp/portage/dev-db/mariadb-5.5.25/work/mariadb-5.5.25_build/gentoo_rules.cmake /var/tmp/portage/dev-db/mariadb-5.5.25/work/mysql gentoo_common_config.cmake contains: SET (LIB_SUFFIX 64 CACHE STRING "library path suffix" FORCE) SET (CMAKE_INSTALL_LIBDIR /usr/lib64 CACHE PATH "Output directory for libraries") I'm at a loss why one way works and the the other doesn't. Thank you.
