Description

Most servers today are 64-bit Linux. Today it is normal servers with 32G of memory where the MapGuide? can not be used by an application 32 bits.

I would be happy to help support and release a 64bit Linux build if we can find a contributor willing to be reponsible for the 64bit builds and releases. At this point no 64bit Linux machine is available.

Milestone: 3.6.03.8.0
Severity: 32

I am testing With:

OS: CentOS release 6.4 (Final)

LSB_VERSION=base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-noarch

Compiler: GCC 4.7

Notes:

1) In order to install the required upgraded GCC 4.7 compiler follow :

http://superuser.com/questions/381160/install-gcc-4-7-on-centos

2) In order to switch to the new compiler run : scl enable devtoolset-1.1 bash

3) to switch back to the original gcc version: exit

4) I also Installed glibc.i686 - "sudo yum install glibc.i686"

As of this comment, the only remaining roadblocks for 64-bit Linux support that I can see based on failing/segfaulting unit tests are:

  • PostGIS: Replace usages of unsigned long (especially if they're being sizeof()'d) with an equivalently sized data type throughout the PostGIS rdbi driver. This is a different size on 64-bit Linux as opposed to windows (32 and 64-bit) and 32-bit Linux. The driver also appears to be selecting the wrong PG data types to use on 64-bit Linux based on unit test failures around overflowing values (eg. PostgreSQL will report: <some astronomical value> is too small for the type smallint)
  • SHP: Replace usages of long and unsigned long (especially if they're being sizeof()'d) with an equivalently sized data type throughout the ShpSpatialIndex? project. Same reason as PostGIS, different size on 64-bit Linux.

King Oracle has more underlying problems (#562 and #649) before we can even consider whether it works on 64-bit Linux.
