[parisc-linux] evms-0.9.2 build utilities problem

[joel.soete]

Hi all,

The original way to build some evms utilities as evms_devnode_fixup is:

...
gcc -Wall -fPIC -O2 -I/tools/evms-dpkg/evms-0.9.2/engine/include
-I/tools/evms-dpkg/evms-0.9.2/engine/dlist
-I/tools/evms-dpkg/evms-0.9.2/kernel-headers/include -I/usr/include
-I/usr/local/include -DPluginDirectory=\"/lib/evms\" -DEVMS_DEBUG -DPARANOID
-DMAJOR_VERSION=1 -DMINOR_VERSION=0 -DPATCH_LEVEL=0 -DVERSION=\"1.0.0\"
-DDATE=\"03/13/02\" -c -o evms_devnode_fixup.o evms_devnode_fixup.c
...
gcc -L/tools/evms-dpkg/evms-0.9.2/engine/Engine
-L/tools/evms-dpkg/evms-0.9.2/engine/dlist  -static -o evms_devnode_fixup
evms_devnode_fixup.o -levms -ldlist -lpthread -ldl

...
Well launch it made an immidiate Segmentation fault.

Now I recompile without "-fPIC" and it works fine.

Any idea on what is wrong?

Thanks in advance for help,
    Joel

what versions of gcc-3.0 and binutils are you running?

dpkg -s gcc-3.0 |grep Version
dpkg -s binutils |grep Version

PS: This can be reproduce with a simple "Hello World" (just to avoid to sempt
time to find back the the sources of evms)

<sigh> yup... looks like a compiler (linker?) bug...

gcc -fPIC -o test test.c          -> works
gcc -fPIC -static -o test test.c  -> segfaults

test.c is a printf("Hello") kinda program

verified with both gcc-3.0.4 and gcc-3.1.

Dave, is this a known problem?

I don't think so.  I did a little test and found r19 has the value 4
when main is called.  There must be a problem with the startup code.
