Hi to all the mailing list.
I'm trying to compile libuhd-3.15 in order to get the static version of
this library, but I've problems. The platform I'm using in ubuntu 18.04
x86_64
the cmake command I use is: cmake -DENABLE_STATIC_LIBS=ON
-DENABLE_LIBERIO=OFF -DENABLE_USB=OFF -DENABLE_B100=OFF
-DENABLE_B200=OFF -DENABLE_E300=OFF -DENABLE_USRP1=OFF
-DENABLE_USRP2=OFF -DENABLE_N230=OFF -DENABLE_MPMD=OFF -DENABLE_E320=OFF
-DENABLE_OCTOCLOCK=OFF -DENABLE_DPDK=OFF ../
The compilation process seems to be ok, but I get from the linker the
error: /usr/lib/x86_64-linux-gnu/libboost_filesystem.a(operations.o):
relocation R_X86_64_PC32 against symbol ......
If I run the command VERBOSE=1 make I can see that the linker command
issued to generate of libuhd.so try to link libbost_*.a files in order
to genertate the libuhd.so file. To be plain I'm not very familiar with
this kind of problems, but I think this is not correct. I did many try
and guess to solve the issue and I found that commenting the line
set(Boost_USE_STATIC_LIBS ${ENABLE_STATIC_LIBS}) in
cmake/Modules/UHDBoost.cmake seems to solve the problem, both libuhd.so
and libuhd.a are generated.
But now another problem arise, when I compile my static application I
get other link errors like:
usr/lib/gcc/x86_64-linux-gnu/7/../../../x86_64-linux-gnu/libdl.a(dlerror.o):
In function `dlerror':
(.text+0x1): undefined reference to `__dlerror'
Because the same application is succesfully compiled on the same system
(so system libraries are exactly the same) using libuhd 3.10.3 I think
these errors could be related with something wrong I did in compiling
libuhd-3.15. Of course every time I need to change libuhd version I
uninstall (through make uninstall) the undesired library.
So my question is, what is wrong with libuhd-3.15 or, better, what I did
wrong?
Thank you for your kindness.
Paolo
