Here is part of an email I sent to the
boinc-projects mailing list:
I am beginning work on a BOINC project and have built and installed BOINC stable. It seems to work fine, attaching to projects and doing work. But, when I try to compile and run a BOINC app standalone I invariably get a seg. fault in diagnostics_init. This has happened both with Eric Myer's 'hello' program and with 'uppercase'. Running uppercase produces a stderr.txt with the following contents:
SIGSEGV: segmentation violationStack trace (9 frames):
./upper_case[0x8051224]
[0x462420]
/lib/libc.so.6(index+0x63)[0x4be0ac33]

./upper_case(__gxx_personality_v0+0xdd)[0x804cc41]

Basically buf
in MIOFILE
is NULL
, because because diagnostics_init
has done an fopen
and passed the results to MIOFILE::init_file
. This sets f
but not buf
.
The response I received from Nicolas Alvarez was:
I'm not sure why this happens in standalone mode, but try creating an
empty file 'init_data.xml' and running app again.
This seemed to get me past this first problem.
