There is some related discussion at http://glest.org/glest_board/index.php?topic=7599.0 I will ExclusiveArch it later today; hopefully there will be an arm port soon :-) maybe it's only the missing SoftFloatWrapper.h header and no need to port when a standard Linux distro is used (In reply to comment #1) > There is some related discussion at > http://glest.org/glest_board/index.php?topic=7599.0 > I will ExclusiveArch it later today; hopefully there will be an arm port > soon :-) They speak about porting to mobile ARM platforms, while we have a full-featured Linux distro, so this kind of port shouldn't be necessary. (In reply to comment #2) > maybe it's only the missing SoftFloatWrapper.h header and no need to port > when a standard Linux distro is used I think it should not be so easy, and/or just getting it built would be of no help if it does not work. Actually, I learned more about megaglest sources when making the review request; previously I was a user that played against bots and with friends :-) Googling I found http://spot.fedorapeople.org/streflop.spec; megaglest has an older version (0.2) and smaller subset of it removing soft float, when comparing to http://nicolas.brodu.numerimoire.net/common/programmation/streflop/streflop-0.3.tar.bz2 contents. Also as specified in the glest forum, the major problem, besides possible issues with streflop would be the port to opengles. Debian related bug report: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=654283 I believe upstream uses streflop for consistent floating point calculations among different architectures and operating systems... Looking at latest upstream sources, following instructions from http://glest.wikia.com/wiki/MG/Getting_The_Code it appears to properly handle it now, and would build on arm. Looking at the changelog from after 3.6.0.3 was released, I see: ------------------------------------------------------------------------ r3090 | mvejvoda | 2012-02-11 13:20:40 -0200 (Sáb, 11 Fev 2012) | 1 line - fixed soft float support so megaglest might now work with other architectures at least in terms of streflop support (In reply to comment #3) > (In reply to comment #1) > > There is some related discussion at > > http://glest.org/glest_board/index.php?topic=7599.0 > > I will ExclusiveArch it later today; hopefully there will be an arm port > > soon :-) > > They speak about porting to mobile ARM platforms, while we have a > full-featured Linux distro, so this kind of port shouldn't be necessary. Please try to check if this package builds on arm: http://fedorapeople.org/~pcpa/855736/megaglest-3.6.0.3-6.fc17.src.rpm it was generated from svn trunk. The version is incorrect, but should be good enough for testing purposes and make a proper report to upstream. It should require more refinement to actually work, but building is a great step :-) it builds successfully on s390x so I think it will also on arm (http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1130499) btw you can test builds on non-x86 (aka secondary) arches yourself, just do eg. arm-koji build --scratch f18-candidate megaglest-3.6.0.3-6.fc17.src.rpm for a test build on F-18 on ARM, replace arm with ppc or s390 for test builds on ppc/ppc64 and s390/s390x (In reply to comment #6) > it builds successfully on s390x so I think it will also on arm > (http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1130499) > > btw you can test builds on non-x86 (aka secondary) arches yourself, just do > eg. > arm-koji build --scratch f18-candidate megaglest-3.6.0.3-6.fc17.src.rpm > for a test build on F-18 on ARM, replace arm with ppc or s390 for test > builds on ppc/ppc64 and s390/s390x It appears armv7hl build failed :-( Looking after testing a x86_64 build patching it to force use of software float streflop, and applying "svn diff -r3089:3090 > megaglest-streflop.patch", and the failure appears almost the same... Either way, I believe it is better to just ExclusiveArch it. Should something be done about the noarch megaglest-data rpm? Otherwise, I believe it is enough to only change megaglest. Ok, then it's fine to add ExclusiveArch. Unless I'm wrong then the ExclusiveArch tag is honored also for noarch package where they are not included in the repositories. Looks like it builds with megaglest 3.7.1 http://arm.koji.fedoraproject.org/koji/taskinfo?taskID=1289123 Can you make make a simple test to check if it also works, or just compiles now? I've not tested it but it builds at least. |
