-----------------------------------
Summary: MADlib cannot be built on PowerPC machines with Linux
Key: MADLIB-1410
URL: https://issues.apache.org/jira/browse/MADLIB-1410
Project: Apache MADlib
Issue Type: Bug
Components: Build System
Reporter: Ivan Leskin
Fix For: v1.17, v1.16
The most recent version of MADlib cannot be built on PowerPC machines with
Linux (CentOS 7) without extra modifications of the build system.
I have encountered the following problems:
h4. Architecture-specific G++ option is set (on all architectures)
The [current CMakeLists.txt sets the
`-mno-sse2`|https://github.com/apache/madlib/blob/fc81374d4d280ab4454150cb126137775e0f7ae6/CMakeLists.txt#L101]
GNU C++ compiler option, which [is
architecture-specific|https://gcc.gnu.org/onlinedocs/gcc-4.8.5/gcc/i386-and-x86-64-Options.html]
and thus not available on PowerPC machines that use GCC to build MADlib.
For this reason, compilation fails, unless this flag is removed from the
CMakeLists.txt manually.
h4. `architecture` cmake macros works incorrectly
The [current cmake `architecture`
macros|https://github.com/apache/madlib/blob/fc81374d4d280ab4454150cb126137775e0f7ae6/cmake/Utils.cmake#L83]
does not work on PowerPC machines with Linux. Its result is empty string.
As a result, M4 variable `<DBMS>_ARCHITECTURE` is not set properly, and the
installation fails.
As far as I understand, there are no fundamental limitations on usage of MADlib
on PowerPC machines with Linux. After some manual actions to resolve the
problems _mentioned above_, I have successfully built and installed MADlib. A
simple check with an example from the quick-start guide showed the correct
results.
I would propose to fix the problems mentioned in order for MADlib to support
PowerPC with Linux properly.
