Hello All,

For your information I’m facing the same issue.

I tried to understand but no idea for the moment:

Build was ok at Dec the 18^th but in January I can’t build with IAR (it is ok with GNU and CLANG)

I didn’t see this before because I mainly use GNU and build with other only before an Uptream to check all compilers are ok for Regression and PSA API tests.

Here is the error message:

"C:\TFM_H5\build_s\build-spe\CMakeFiles\tfm_s.rsp",21  Fatal error[Ms007]:

          could not open file "libtfm_s_build_flags.a"

            Directories searched:

              C:\TFM_H5\build_s\build-spe

Fatal error detected, aborting.

Note in that case it is on STM32H5 but I also faced the same issue on other platforms.

However before in the build there is also a FAILED:

So issue seems due to :

Directory content, there is no TF-M-build file

c:\TFM_H5\build_s\temp\src\TF-M-stamp\TF-M-configure

c:\TFM_H5\build_s\temp\src\TF-M-stamp\TF-M-source_dirinfo.txt

Here is the build command:

build_H5_regression_iar_s()

{

cmake -S $TFM_work_dir_H5/tf-m-tests/tests_reg/spe -B $H5_build_s -GNinja -DTFM_PLATFORM=stm/stm32h573i_dk -DTFM_TOOLCHAIN_FILE=$H5_tfm_src/toolchain_IARARM.cmake -DCONFIG_TFM_SOURCE_PATH=$H5_tfm_src -DTEST_S=ON -DTEST_NS=ON

cmake --build $H5_build_s -- install

}

Also note:

I use main branch

It is ok on v2.2.2

Thank you.

Hey,

I think it is just missed. Hopefully, a dummy interface library will be enough, like it was for Armclang.
