Capi/au/cpuid/cpuid.h: No such file or directory

When I try to compile libflame on a fresh Debian 11 t3.small EC2 instance, I get

Compiling src/base/flamec/main/FLA_Context.c                                    
src/base/flamec/main/FLA_Context.c:25:10: fatal error: Capi/au/cpuid/cpuid.h: No
 such file or directory

      |          ^~~~~~~~~~~~~~~~~~~~~~~                                        
compilation terminated.                                                         

and when I try to use the precompiled libflame.a packaged in aocl-linux-gcc-5.1.0.tar.gz when linking just libblis and libflame (which worked under AOCL 4.0), I get the related

/usr/bin/ld: /home/admin/aocl/5.1.0/gcc/lib/libflame.a(FLA_Context.c.o): in function `fla_isa_init':
FLA_Context.c:(.text+0x36a): undefined reference to `au_cpuid_has_flags'
/usr/bin/ld: FLA_Context.c:(.text+0x390): undefined reference to `au_cpuid_has_flags'

Update: the libflame.a compile error was fixed by linking in libau_cpuid.a . But I'm guessing that you also want libflame to compile for others from source.

Hi Christopher,

AOCL-LAPACK( AMD optimized libflame) has dependency on AOCL-Utils library in addition to a BLAS library. This dependency was introduced from AOCL 4.2 release. The details on building AOCL-LAPACK library and linking are in AOCL User Guide which can be referred from AOCL Developer portal under Documentation section.

Copying the snippet from user guide:

$ export AOCL_ROOT=""

Using 32-bit Integer (LP64)

$ cmake ../ -DENABLE_AMD_FLAGS=ON -DENABLE_AOCL_BLAS=ON
-DCMAKE_INSTALL_PREFIX=

Using 64-bit Integer (ILP64)

$ cmake ../ -DENABLE_ILP64=ON -DENABLE_AMD_FLAGS=ON
-DENABLE_AOCL_BLAS=ON -DCMAKE_INSTALL_PREFIX=

Let me know if you have any further queries.
