/usr/bin/ld: ../utils/cryptoutils.o:/opt/ibmtss2.1.1/utils/cryptoutils.c:118: multiple definition of `tssUtilsVerbose'

[belongtothenight]

My building system and software details are listed below.

• Raspberry Pi 4 B
• 2023-05-03-raspios-bullseye-arm64.img.xz
• ibmtss2.1.1.tar.gz
• Built for SWTPM
• Built for both TPM 1.2 & 2.0

Build command:

# Set Env Var
export TPM_INTERFACE_TYPE=socsim
export TPM_COMMAND_PORT=2321
# Clear Previous Build
cd "${ibmtss_path}/utils/"
make -f makefiletpmc clean
cd "${ibmtss_path}/utils12/"
make -f makefiletpmc clean
# Build
cd "${ibmtss_path}/utils/"
make -f makefiletpmc
cd "${ibmtss_path}/utils12/"
make -f makefiletpmc

The following issue appears when using 2023-05-03-raspios-bullseye-arm64.img.xz, but not in Ubuntu 18.04.6 VM.

/usr/bin/ld: ../utils/cryptoutils.o:/opt/ibmtss2.1.1/utils/cryptoutils.c:118: multiple definition of `tssUtilsVerbose'; nvreadvalueauth.o:/opt/ibmtss2.1.1/utils12/nvreadvalueauth.c:56: first defined here
collect2: error: ld returned 1 exit status
make: *** [makefiletpmc:175: nvreadvalueauth] Error 1

Currently, trying to downgrade to version 1.6.0 which this problem doesn't exist according to my research colleague's test on the same platform. Hope this issue can help solving this issue.

Thanks. I don't have a Debian to test, but I test with several Ubuntu versions and I don't see the error. Can you please try the next branch. If it's OK, I'll merge to master.

Sure!, I will try the source code from GitHub instead of SourceForge and let you know!

Relatively same building environment (VM) can be created with this YouTube video steps: https://www.youtube.com/watch?v=85ZJj00FKe0

It's a bit out of date but still useful. The created VM can survive through system update and a few times of software building, but will eventually freeze.

1. Can you please try a simple, single threaded build. When you run a multi-theaded build, the error messages interleave and I can't tell where it fails.
2. Do you really need the TPM 1.2 experimental TSS? It's long obsolete. If you just need TPM 2.0, can you declare success and go on to application development.
3. There seems to be some ussue with the linker path. There is a comment in the makefile about Ubuntu and the linker. See -fuse-ld=bfd. Does it help? -L. should look in the current directory. Is the .so there?

Above results are tested with latest code pulled from GitHub. However the latest release v2.2.0 (yesterday) is not presented on SourceForge, I can't test it.

Thank you for the fix and your work!!

Sorry for the late reply, I was on vocation last week for the lunar new year.

2. Do you really need the TPM 1.2 experimental TSS?  It's long obsolete. If you just need TPM 2.0, can you declare success and go on to application development.

If my understanding is correct, the directory utils holds utilities for TPM 2.0; directory utils12 holds utilities for TPM 1.2; so it's completely find if I skip building process in utils12?

3. There seems to be some ussue with the linker path. There is a comment in the makefile about Ubuntu and the linker.  See -fuse-ld=bfd.  Does it help?  -L. should look in the current directory.  Is the .so there?

Uncommented both makefiletpmc -fuse-ld=bfd line.

Build command:

# Set Env Var
export TPM_INTERFACE_TYPE=socsim
export TPM_COMMAND_PORT=2321
# Single threaded utils build -> SUCCESS
cd "${ibmtss_path}/utils/"
make -f makefiletpmc 2>&1 | tee ${path_of_log}

# Multi-threaded utils12 build -> SUCCESS
cd "${ibmtss_path}/utils12/"
make -f makefiletpmc -j$(nproc) 2>&1 | tee ${path_of_log}

Terminal output referes to the following files: Branch info: origin/master Single threaded build output in directory */utils/ (SUCCESS): TSS_utils_5.log Single threaded build output in directory */utils12/ (SUCCESS): TSS_utils12_5.log Multi-threaded build output in directory */utils/ (SUCCESS): TSS_utils_6.log Multi-threaded build output in directory */utils12/ (SUCCESS): TSS_utils12_6.log

Editing the line doesn't show much difference to my case. As for the so files in the same directories, I found the following files:

$ls "${ibmtss_path}/utils" | grep .so
libibmtss.so
libibmtss.so.2
libibmtss.so.2.2
libibmtssutils.so
libibmtssutils.so.2
libibmtssutils.so.2.2
$ls "${ibmtss_path}/utils12" | grep .so
libibmtssutils12.so
libibmtssutils12.so.0
libibmtssutils12.so.0.1

Correct. The TPM 1.2 code was an experiment at a unified TSS. Use makefiletpm20 or autotools configured for TPM 2.0

I haven't created a tar file yet but if git is working, you're done.

May I ask roughly when will you officially release v2.2.0 on Sourceforge?
