Segfault with 6.4.5, 6.7.5

[shiki08]

First, I installed 'boinc' from community repo. It wasnt working at all. then I tried to build them both (6.4.5, 6.7.5). First, I failed with 6.4.5. (Used Arch linux ABS system). Then downloaded it from SVN (tagged), tried to compile that way. (Disabled the gui for faster speed (cuz X sucks :))).

That way it compiles. BUT. I launch the 'boinc_client' and I get this (I get the same when I try to run 6.4.5 !!! ..I can paste that too):

If you need any info, I'll answer ASAP. \ Sorry for setting prior BLOCKER, but it is really a blocker if I cant even start it. \

How could I post a debug info? Compiled it with -debug flag, but ... strace gives 8MB or 180mb file... GDB? Something?

Not a blocker if you're the only one (so far) with the problem.

[Nicolas]

Remove -O2 from the flags and add -g. Recompile.

Run gdb boinc and type run in the (gdb) prompt. Once it crashes, type bt.

Replying to shiki08:

What IRC channel?

Tiffanyand > WTF?

It was spam.

Added what you asked (btw it was Arch linux IRC):

CFLAGS="-march=core2 -mtune=core2 -ffast-math -fomit-frame-pointer -mmmx -msse -msse2 -msse3 -CXXFLAGS="${CFLAGS} ./configure

This way it configures, (without --enable-optimize).

Now, it doesnt compiles: ​http://pastebin.com/f5cbbb448

Any idea?

[Nicolas]

You have your quote marks wrong; it's passing "-CXXFLAGS=" as one of the CFLAGS! Compare:

CFLAGS="-march=core2 -mtune=core2 -ffast-math -fomit-frame-pointer -mmmx -msse -msse2 -msse3 -CXXFLAGS="${CFLAGS} ./configure

CFLAGS="-march=core2 -mtune=core2 -ffast-math -fomit-frame-pointer -mmmx -msse -msse2 -msse3" CXXFLAGS="${CFLAGS}" ./configure

[shiki08]

No difference... oO

Disabled --fast-math:

The error exactly (as you can see it): ../lib/str_util.h:41: error: new declaration ‘char* strcasestr(const char*, const char*)’ /usr/include/string.h:367: error: ambiguates old declaration ‘const char* strcasestr(const char*, const char*)’

[shiki08]

This was 6.7.5 as you can see it. Should I get the NEWEST version (from SVN) , or I should keep trying with the 6.4.5 ?

[Nicolas]

You were initially reporting a segfault. Now you're having build errors; totally different problem.

Try to build 6.4.5 and see if you can reproduce the segfault. If you can't even compile it, please open a separate ticket.

[shiki08]

Okay, I was able to compile and run 6.4.5.

First of all, some BOINC install (I suppose it was the 6.7.5 version) made my partition dirty, so I just removed all files by "sudo updatedb && locate -i 'boinc'". By hand. :)

Then did this: 1) Got source from SVN 2) patch -p0 < gcc4.4.0.patch 3) ./_automake 4) CFLAGS="-march=core2 -mtune=core2 -mmmx -msse -msse2 -msse3 -g" CXXFLAGS="${CFLAGS}" ./configure --prefix=/usr 5) make 6) sudo make install

Now it works.. SO FAR (and I cant make libcudart.so thingie work). Ticket can be closed. Reopening a new one with the 6.7.5 compiling issue (if there is no such ticket so far. Thanks for your help.)
