Hi,
these atomicstuff is not that much tested. And indeed you found a bug. Can you
try this patch:
Index: atomicity.gcc.arm.cpp
===================================================================
--- atomicity.gcc.arm.cpp (revision 1131)
+++ atomicity.gcc.arm.cpp (working copy)
@@ -125,7 +125,7 @@
: "=&r" (a), "=&r" (b)
: "r" (&dest), "r" (exch), "r" (comp)
: "cc", "memory");
- return a;
+ return (void*)a;
}
You will run into another problem with tntnet when cross-compiling. Tntnet
will compile the ecpp compiler ecppc and use it to compile the demos. This
won't work when cross-compiling since the ecpp compiler won't work on the host
system. Luckily tntnet is already prepared for that. You can disable compiling
the demos with the configure switch --without-demos. Actually you don't even
need to compile ecppc for the target system so you may want to use --without-
sdk, which disables the ecpp tools and the demos.
Tntnet was cross compiled for FreeWRT and OpenWRT and other embedded systems.
So you may want to look at the ports for help.
