Package: libgeographiclib-dev
Version: 1.21-1
Severity: important
Dear Maintainer,
I war trying to build a shared library that uses some coordinates conversion
routines implemented by geographic lib.
I need to distribute my shared library (it will be used by a python
application).
I would not like my application to depend on package libgeographic (that is, I
would like to avoid that the user needs to install or copy
/usr/lib/libGeographic.so.9 in it's system)
For these reasons I need to embed in my library the object code that is in
libGeographic.a
But while doing this, the compiler complains that:
/usr/bin/ld:
/usr/lib/gcc/x86_64-linux-gnu/4.7/../../../../lib/libGeographic.a(MGRS.o):
relocation R_X86_64_32S against `_ZTVN13GeographicLib13GeographicErrE' can not
be used when making a shared object; recompile with -fPIC
This happens (in my understanding) because the MGRS.o was compiled from
MGRS.cpp without passing the -fPIC option to the compiler.
So, please consider adding this option to your compiler build; without this
option, the libGeographic.a can be used only to build self-contained
executables and not self-contained libraries, that are preferred/needed when
you are trying to integrate the library in a cpython environment (in my case I
was trying to deliver a QGIS plugin).
Thanks, larzeni

Hi,
I am closing this bug, because the build log confirms that geographiclib
was (from at least from v1.35 up to v1.39) building with the -FPIC option.
Regards,
Ross
