[cmake-developers] cmake on AIX

[REIX, Tony]

Hi Brad,


Thanks for the information!


About MariaDB current issue, the only trace I see dealing with the string breaking cmake is:


/opt/freeware/src/packages/BUILD/mariadb-10.3.1/64bit/libmariadb/cmake/FindGSSAPI.cmake(94):  message(STATUS Found GSSAPI: ${GSSAPI_LIBS} )
-- Found GSSAPI: -L/opt/freeware/lib -blibpath:/opt/freeware/lib::/usr/lib:/lib -I/usr/include -I/opt/freeware/include -L/opt/freeware/lib -blibpath:/opt/freeware/lib:/usr/lib:/lib
-bmaxdata:0x80000000 -brtl -lgssapi_krb5 -lkrb5 -lk5crypto -lcom_err -lpthreads


It contains a part of this:

# grep bmaxdata mariadb-10.3.1-1.spec
        export LDFLAGS="-L/opt/freeware/lib -Wl,-blibpath:/opt/freeware/lib:/usr/lib:/lib -Wl,-bmaxdata:0x80000000 -lintl"

And the rest of the string probably comes from KRB5 configuration files:
# rpm -ql krb5-devel-1.9.4-2 | xargs grep lkrb5
/opt/freeware/bin/krb5-config:  lib_flags="$lib_flags -lkrb5 -lk5crypto -lcom_err $GEN_LIB $LIBS $DL_LIB"
/opt/freeware/bin/krb5-config_64:       lib_flags="$lib_flags -lkrb5 -lk5crypto -lcom_err $GEN_LIB $LIBS $DL_LIB"


So, it looks like cmake gets data for the CMAKE_REQUIRED_LIBRARIES from these 2 aboves places, but it does not transform the " " blank separators by ";" ?!!

Any idea where this is done ?


Regards,


Cordialement,

See the Testing/* directory.  When not running in dashboard
client mode there isn't much logged though.

I suspect mariadb's source is setting CMAKE_REQUIRED_LIBRARIES
to a space-separated value instead of a ;-separated value.

See the code here:

  https://github.com/MariaDB/server/blob/ed0b84a027/plugin/auth_gssapi/CMakeLists.txt#L22-L24

It assumes GSSAPI_LIBS is ;-separated, but the cache entry you
quoted is a command-lien string with spaces.
