I'm compiling an executable called "interrogate" with:
g++ -o built/bin/interrogate -Lbuilt/lib -Lbuilt/tmp -L/usr/X11R6/lib \ built/tmp/interrogate_composite1.o built/tmp/interrogate_composite2.o \ -lp3cppParser -lp3dtool -lp3dtoolconfig -lp3pystub -pthread -ldl
After the compilation, when i try to execute the executable:
$ LD_LIBRARY_PATH=built/lib built/bin/interrogate built/bin/interrogate: symbol lookup error: built/lib/libp3dtool.so.1.8: undefined symbol: _Py_NoneStruct
This symbol is provided by the libp3pystub.so, but the interrogate executable doesn't have any reference to this library (I did used the -lp3pystub):
$ LD_LIBRARY_PATH=built/lib ldd built/bin/interrogate linux-vdso.so.1 => (0x00007fff2016a000) libp3dtool.so.1.8 => built/lib/libp3dtool.so.1.8 (0x00007f498d57a000) libp3dtoolconfig.so.1.8 => built/lib/libp3dtoolconfig.so.1.8 (0x00007f498d51b000) libstdc++.so.6 => /usr/lib/x86_64-linux-gnu/libstdc++.so.6 (0x00007f498d1f2000) libgcc_s.so.1 => /lib/x86_64-linux-gnu/libgcc_s.so.1 (0x00007f498cfdc000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007f498cdbf000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007f498c9ff000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007f498c7fb000) libm.so.6 => /lib/x86_64-linux-gnu/libm.so.6 (0x00007f498c4ff000) /lib64/ld-linux-x86-64.so.2 (0x00007f498d5bc000)
If i manually load the libp3pystub.so, the executable works:
$ LD_PRELOAD=built/lib/libp3pystub.so LD_LIBRARY_PATH=built/lib built/bin/interrogate Usage: interrogate [opts] file.C [file.C ...] interrogate -h
My question is: why the library i've added with -lp3pystub
is not referenced by the interrogate
executable?
