Regarding tbb error

[Deepika Kushwah]

Hello Everyone,

I am a beginner in deal.II.

While running any tutorial on centos7 I am getting the following errors (please see attachments).

How to proceed?

Thanks & Regards

Deepika

Hello Deepika,

which version of deal.II are you using?

From your screenshots, it looks like you are using Intel oneAPI TBB. We started to support oneAPI versions with deal.II 9.4.0. Could you try our latest release?

Thanks for the reply.

I am using the latest version of dealii 9.4.0.

With this version I am getting the error as mentioned in the previous email.

Thanks & Regards

Deepika

Dear all,

I just encounter a similar issue and am wondering if there is a solution to fix it.

Please see the attachment for the error message I got. This message is from dealii 9.4.0 (I also tried dealii 9.4.2 and got a similar message.). 

During the installation of dealii 9.4.0, no issue is showing up though (The installation is carried out by using candi. I also attach the log here.). The tbb I used is "tbb/2021.6.0" (Intel(R) oneAPI Threading Building Blocks for intel64).

Any comment or suggestion is greatly appreciated.

Best Regards,

Jau-Uei Chen

Hello Jau-Uei Chen,

the configuration did not pick up the TBB version you provided, and instead uses the version that comes bundled with deal.II (i.e. tbb 2018U2). However, the linker still tries to link against tbb 2021.6.0. Something got mixed up in the configuration phase.

Interestingly, the cmake configuration also complains about the following unused variable. This variable is now named DEAL_II_FORCE_BUNDLED_TBB. Can someone of the candi developers have a look?

CMake Warning:

    DEAL_II_FORCE_BUNDLED_THREADS

Dear all,

I found that the issue can be resolved by module unload "tbb/2021.6.0" (The tbb I thought will be used). It seems that candi is trying to build the tbb/2018U2 when the flag "DEAL_II_FORCE_BUNDLED_TBB" is set to be on (I saw that in build directory there is a directory called "bundled" where I can find "tbb-2018_U2").
