Installation problem

[Ailinux]

hello,
I try to install Spring in my machine Opensuse 12.1, but still this problem :

Code: Select all

Linking CXX executable ../../../spring                                                                                                                                              
/usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: ../../lib/pp/libpp-supplier.a(PP_Supplier.cpp.o): undefined reference to symbol 'shm_open@@GLIBC_2.2'          
/usr/lib/gcc/i586-suse-linux/4.6/../../../../i586-suse-linux/bin/ld: note: 'shm_open@@GLIBC_2.2' is defined in DSO /lib/librt.so.1 so try adding it to the linker command line
/lib/librt.so.1: could not read symbols: Invalid operation
collect2: ld returned 1 exit status

make[1]: *** [rts/builds/default/CMakeFiles/spring.dir/rule] Erreur 2
make: *** [spring] Erreur 2

thank you for your help

where does lib/pp/libpp-supplier.a(PP_Supplier.cpp.o) come from?

it seems like spring for some reason links to that lib but this also requires librt.so.1 / -lrt as linker flag.



i'm also confused about this error:

/lib/librt.so.1: could not read symbols: Invalid operation

is this file maybe broken?

what does

Code: Select all

ldd /lib/librt.so.1

output?

I do not know what is the problem I followed the installation guide, but it does not work, I do not know what is missing, thank you for your help.

[abma]

please answer my questions...

hi guys,
I found the solution, I added-lrt in the makefile.
but now I have another problem, I ran the second command "make install-spring" and I get this error:

you have an idea of what I'm missing
thank you

[abma]

just disable the java ai's / interface in CMakeCache.txt
AI_TYPES:STRING=NATIVE

(this / similar errors where caused by differences between awk/gawk which is used to generate the java code....)

[Ailinux]

thank you guys, all works fine.
