This appears to be a regression that got in during 2.8 rc2 and 2.8 proper.
|
|
(between the /8/ build and the /9/ build). I was able to cross-compile 2.8 rc2
|
|
, on an up-to-date fedora 13 x86_64 box.
|
|
|
|
but with 2.8 proper a couple of weeks later, some "error: 'SIGTRAP' undeclared"
|
|
happens:
|
|
|
|
---------------------------
|
|
./../../mono/mini/method-to-ir.c: In function 'get_basic_blocks':
|
|
./../../mono/mini/method-to-ir.c:4938: error: 'SIGTRAP' undeclared (first use
|
|
in this function)
|
|
./../../mono/mini/method-to-ir.c:4938: error: (Each undeclared identifier is
|
|
reported only once
|
|
./../../mono/mini/method-to-ir.c:4938: error: for each function it appears
|
|
in.)
|
|
./../../mono/mini/method-to-ir.c: In function 'mono_method_to_ir':
|
|
./../../mono/mini/method-to-ir.c:5513: error: 'SIGTRAP' undeclared (first use
|
|
in this function)
|
|
./../../mono/mini/method-to-ir.c:5598: warning: implicit declaration of
|
|
function 'alloca'
|
|
./../../mono/mini/method-to-ir.c:5598: warning: incompatible implicit
|
|
declaration of built-in function 'alloca'
|
|
make[4]: *** [libmono_2_0_la-method-to-ir.lo] Error 1
|
|
-------------------
|
|
|
|
For 2.8, inserting into "mono/mini/method-to-ir.c" and
|
|
"mono/mini/mini-exceptions.c" the following snipplet:
|
|
|
|
#ifndef SIGTRAP
|
|
#define SIGTRAP 5
|
|
#endif
|
|
|
|
allows the cross-compile to continue to completion.
|
|
|
|
For git head, "mono/mini/mini.c" also needs this snipplet. It seems to be due
|
|
to some sort of recent changes in the area of exceptions.
|
|
|
|
Reproducible: Always
|
|
|
|
Actual Results:
|
|
compilation fails with error "SIGTRAP" undeclared
|
|
|
|
Expected Results:
|
|
compilation goes to completion.
