Exactly same issue on 10.0.5.

Same thing on 5.5.32.
When building 32-bit version (no -m64 flag) - a bit different error set:

[...]

Just in case someone got interested: building with SolarisStudio fails too, but in different way:

How did you build? I'm building with gcc and your CFLAGS/CXXFLAGS/LDFLAGS and don't get this error, my_context.c is compiled successfully.

Well... as usual:

export CFLAGS="-g -m64"
export CXXFLAGS="-g -m64"
export LDFLAGS="-g -m64"

cmake -DCMAKE_INSTALL_PREFIX=/usr/local/mariadb
(cmake went just fine)
gmake

I've also tried to use a newer gcc 4.7.2 on a Solaris 10 x86 - got similar bunch of assembler errors.
Flags that I mentioned I took from a mariadb documentation, thought may be using them I'll get more luck but I didn't.

We have Solaris11 x86-64. MariaDB 10.0 builds there just fine (since yesterday).
I'll close this bug when I verify that MariaDB 5.5 builds fine too. Meanwhile I'll keep it open.

Hi,

last MariaDB 10.0 which I managed to compile with gcc 3.4.3 on OpenIndiana was 10.0.8

When I try 10.0.10 it fails:

any clue?

Used this script:

export MariaDB=10.0.10
path=`dirname $0`
. "$path/SETUP.sh"
extra_flags="-D__sun -m32"
extra_configs="$max_configs --with-libevent"

LDFLAGS="-lmtmalloc -R/usr/gnu/lib -R/usr/sfw/lib"
export LDFLAGS

export just_configure=1

. "$path/FINISH.sh"

sed -i "s#CMAKE_INSTALL_PREFIX:PATH=/usr/local/mysql#CMAKE_INSTALL_PREFIX:PATH=/opt/MariaDB/${MariaDB}#g" CMakeCache.txt
sed -i "s#INSTALL_SYSCONFDIR:STRING=#INSTALL_SYSCONFDIR:STRING=/opt/MariaDB/${MariaDB}/etc#g" CMakeCache.txt

gmake -j1

Thank you and regards.
