Summary0000262: Mercury doesn't compile on NetBSD
DescriptionMercury programming language doesn't compile in NetBSD operating system. I tried to compile it using from NetBSD source package management (pkgsrc). It ended up with error:

os_dep.c:503:9: error: redefinition of 'GC_data_start'
os_dep.c:454:9: note: previous definition of 'GC_data_start' was here
gmake[3]: *** [os_dep.o] Error 1
gmake[3]: Leaving directory `/usr/pkgsrc/lang/mercury/work/mercury-compiler-11.07/boehm_gc'
gmake[2]: *** [submake] Error 2
gmake[2]: Leaving directory `/usr/pkgsrc/lang/mercury/work/mercury-compiler-11.07/boehm_gc'
gmake[1]: *** [boehm_gc] Error 2
gmake[1]: Leaving directory `/usr/pkgsrc/lang/mercury/work/mercury-compiler-11.07'
gmake: *** [install] Error 2
*** Error code 2

Stop.
make: stopped in /usr/pkgsrc/lang/mercury
*** Error code 1

Stop.
make: stopped in /usr/pkgsrc/lang/mercury

It seems that solution is simple. I commented two duplicate definitions GC_data_start and GC_find_limit as they were defined exactly the same a bit earlier in the same file (see lines 454-456). Mercury compiled fine then. I looked into current version of os_dep.c file and it is the same (pkgsrc retrieves mercury-compiler-11.07.tar.gz currently) because of this it should fail too.
Steps To ReproduceCompile mercury on netbsd.

I've tried the source distribution for the latest stable release (13.05) on NetBSD 6.1 (i386) and it
appears to be fine. I'll do some further testing since I also have a patch that enables support for shared libraries on that platform.

If there are problems with the version in pkgsrc then they are best taken up with the maintainer of that package. (The version of the Boehm GC that is shipped with Mercury has been bumped several times since the 11.07 release; my best guess is that the newer versions probably fix the problems encountered above.)
