Linking problem on x86_64 Android with static libraries

Agmon__Morag — Wed, 14 Feb 2018 12:39:02 GMT

I am getting a linker error when I try to build a shared library with static linking of the Android IPP libraries for x86_64 (intel64):

Android/Sdk/ndk-bundle/build//../toolchains/x86_64-4.9/prebuilt/windows-x86_64/lib/gcc/x86_64-linux-android/4.9.x/../../../../x86_

64-linux-android/bin\ld: error: libipps.a(pscosm7l9as_y8.o): requires dynamic R_X86_64_PC32 reloc against 'y8_ownsCosOne_m7y8' w

hich may overflow at runtime; recompile with -fPIC

Same build for x86 (32-bit) works just fine.

Any hint ?

Morag, which IPP version are

Morag, which IPP version are you using? We notice one issue in 2017 release, but it was fixed in the IPP 2017 package.

Thanks,
Chao

Hi Morag,

you are right, several internal symbols in IPP (libipps.a) have wrong ".global" attribute that lead to the issue you've faced with:

000000000a51 000800000002 R_X86_64_PC32 0000000000000000 y8_ownsCosOne_m7y8 - 4
0000000010e1 001900000002 R_X86_64_PC32 0000000000000000 y8_ownsExpOne_m7 - 4
0000000010e6 001a00000002 R_X86_64_PC32 0000000000000700 y8_ownsExpOneF_m7 - 4
000000000dd1 002700000002 R_X86_64_PC32 0000000000000000 y8_ownsPowOneF_m7 - 4
000000004111 003f00000002 R_X86_64_PC32 0000000000000000 y8_ownsPowOne_m7 - 4
000000000a81 000900000002 R_X86_64_PC32 0000000000000000 y8_ownsSinOne_m7y8 - 4
000000001951 000900000002 R_X86_64_PC32 0000000000000000 y8_ownsTanOne_m7 - 4

already fixed, the fixed libs will be available in the nearest future in the further IPP releases/updates.

Issue still exists in 2018.2.199 (2018 Update 2).

In which version can you commit for a fix ?

Hi Morag,

Hi Morag,

the code freeze and final build for upd#2 was significantly earlier than you had submitted the bug. It is fixed in 2018 upd#3 and 2019 gold, upd#3 will be available on the web somewhere on/after ww22.3 (May, 30).
