Installation fails on OS X using Homebrew

[Gergo Erdosi]

Hi,

I'm trying to install Percona Server on OS X using Homebrew, however
unable to compile it. Please see this ticket for details:
https://github.com/mxcl/homebrew/issues/12075

I managed to fix some of the errors, however there is one that I
couldn't solve yet:

[ 97%] Building CXX object sql/CMakeFiles/mysqld.dir/main.cc.o
Linking CXX executable mysqld
Undefined symbols for architecture x86_64:
"__increment_page_get_statistics", referenced from:
_buf_page_get_gen in libinnobase.a(buf0buf.c.o)
_buf_page_optimistic_get in libinnobase.a(buf0buf.c.o)
_buf_page_get_known_nowait in libinnobase.a(buf0buf.c.o)
ld: symbol(s) not found for architecture x86_64

The formula uses these flags:

args = std_cmake_parameters.split + [
".",
"-DMYSQL_DATADIR=#{var}/percona",
"-DINSTALL_MANDIR=#{man}",
"-DINSTALL_DOCDIR=#{doc}",
"-DINSTALL_INFODIR=#{info}",
# CMake prepends prefix, so use share.basename
"-DINSTALL_MYSQLSHAREDIR=#{share.basename}",
"-DWITH_SSL=yes",
"-DDEFAULT_CHARSET=utf8",
"-DDEFAULT_COLLATION=utf8_general_ci",
"-DSYSCONFDIR=#{etc}",
"-DCMAKE_BUILD_TYPE=RelWithDebInfo"
]

Can anybody tell me what could be the source of this error? You can
reply on Github too in the ticket. Thanks in advance!

The reason is the differences in the default inline semantics between
GCC and Clang. I have reported it as
https://bugs.launchpad.net/percona-server/+bug/997496

The workaround is to build with GCC. And the fix is to change
_increment_page_get_statistics() to a static inline function:

@@ -57,7 +57,7 @@
/* prototypes for new functions added to ha_innodb.cc */
trx_t* innobase_get_trx();

-inline void _increment_page_get_statistics(buf_block_t* block, trx_t* trx)
+static inline void _increment_page_get_statistics(buf_block_t* block,
trx_t* trx)
{
ulint block_hash;
ulint block_hash_byte;

Best regards,
Alexey.

Hi Alexey,

Thanks, that was the problem! I was able to compile Percona Server
now. Homebrew is able to patch packages, so I decided to fix it
instead of the workaround. I'll remove the patch when a new release of
Percona Server comes out with the fix. Thanks for your help!
