Hi All,
I have downloaded the IPsec mult-buffer library (ipsec_043.zip) from Intel
site (mentioned at http://dpdk.org/doc/guides-16.04/cryptodevs/aesni_mb.html)
and compiled it using #make YASM=/usr/bin/yasm. Upon trying to create a
shared library from static library using #gcc -shared -Wl,--whole-archive
libIPSec_MB.a -o libIPSec_MB.so, it gives the below link error.
/usr/bin/ld: libIPSec_MB.a(aes128_cntr_by4_sse.o): relocation R_X86_64_PC32
against symbol `byteswap_const' cannot be used when making a shared object;
recompile with -fPIC
/usr/bin/ld: final link failed: Bad value
collect2: error: ld returned 1 exit status
[root at mgmt-rig-7 code]#
The version of yasm is 1.3.0. The release note at
http://yasm.tortall.net/releases/Release1.3.0.html clearly says that,
yasm-1.3.0 has a full support for shared objects. Then why it gives
aforesaid error. Can anyone please let me know if I am missing anything or
it is an issue with yasm? Thank you in advance for your support and time.
Please feel free to let me know if additional information is needed.
Here are the procedures followed to configure and install yasm.
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -xvzf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure && make -j 4 && sudo make install
[root at local code]# /usr/bin/yasm --version
yasm 1.3.0
