[Mono-dev] Build problems

[Neale Ferguson]

Over the last couple of days I’ve had problems building from head on
s390x. 

(1) When I use 3.6.1 I get:

The code looks correct in those files, it appears to be a compiler error.
I tried initializing the variable ch but that results in a different
problem.

(2) When I use monolite-latest things go bizarre and appear endian-related:

/home/neale/Mono/mono/mcs/class/lib/monolite/basic.exe:
/home/neale/Mono/mono/mcs/class/lib/monolite/basic.exe: cannot execute

make[6]: *** [build/deps/basic-profile-check.exe] Error 126
*** The compiler '/home/neale/Mono/mono/mcs/class/lib/monolite/basic.exe'
doesn't appear to be usable.
