[aspect-devel] [deal.II] Re: deal.ii problem during aspect compile, static libs

[Thorsten Becker]

Thanks much, Wolfgang and Timo, for your quick reply and comments!

This all makes sense, but I am not sure if any of it applies for me. I
spent a day+ trying to compile shared libraries, that's how I ended up with
my static attempts. (I should have kept track of the shared compilation
problems, and might go back and document those.) During the whole process,
I tried to make sure to have "clean" compiles on the same head node, with
the same compilers and libraries.

In the end, adding a -DCMAKE_EXE_LINKER_FLAGS="-static" to the deal
compiled "worked", though now both the test problems and Aspect are stuck
on something like

Linking CXX executable aspect
/usr/lib/../lib64/libpthread.a(libpthread.o): In function `sem_open':
(.text+0x774d): warning: the use of `mktemp' is dangerous, better use
`mkstemp'
/usr/usc/mpich2/1.5/lib/libmpich.a(simple_pmi.o): In function `PMI_Init':
simple_pmi.c:(.text+0xc89): warning: Using 'gethostbyname' in statically
linked applications requires at runtime the shared libraries from the glibc
v
ersion used for linking
/usr/bin/ld: dynamic STT_GNU_IFUNC symbol `strcmp' with pointer equality in
`/usr/lib/../lib64/libc.a(strcmp.o)' can not be used when making an execut
able; recompile with -fPIE and relink with -pie
collect2: error: ld returned 1 exit status
make[2]: *** [aspect] Error 1
make[1]: *** [CMakeFiles/aspect.dir/all] Error 2
make: *** [all] Error 2

This makes me think that there's still something wrong with the compiler
versions, or that the link line doesn't take into account -static. I wonder
(and Rene's been giving me good suggestions all along) if I should really
heed the -pie advice, or rather try something else?

Thanks!
