2021.05.002: configure still tests avx when avx is disabled by --disable-avx --disable-avx2 about elpa HOT 2 CLOSED

Could you please provide the configure command line you have used?
I cannot reproduce the error, that is I only obtain messages like
"configure: error: Could not compile a test program with AVX512, adjust the C compiler or CFLAGS. Possibly (some of) the flags " -mmmx -msse -msse2 -mssse3 -msse4.1 -msse4.2 " solve this issue"
when avx512 has been configured "--enable-avx512" (notice that this is the default) but the CFLAGS are not set accordingly.

According from your error description I assume you set "--disable-avx --disable-avx2" but the it was still tested for AVX512 since the is enabled by default. Adding a "--disable-avx512" should solve the issue.

Ok, this does not rely give more insight.
Maybe you can do the following:

• change the file configure.ac: replace
  else need_manual_cpp=no fi
  with
  else need_manual_cpp=yes fi
• run ./autogen.sh
• re-run your configure call and then V=1 make
• provide the output if the error is still persistent
