You are correct. The optional LAPACK compatibility layer lapack2flame has not been compiled into the libflame binary published by AMD.
We are planning to publish new binaries with lapack2flame enabled, in near future.
In the mean time, I can help you with building libflame from source available on AMD's Github page: GitHub - amd/libflame: High-performance object-based library for DLA computations
To get the source:
git clone https://github.com/amd/libflame.git
Build libflame:
cd libflame
./configure --enable-lapack2flame --disable-autodetect-f77-ldflags --disable-autodetect-f77-name-mangling --enable-cblas-interfaces
make
make install
Build sample app:
gfortran sample_app.f -I/path/to/libflame/include/ /path/to/libflame.a /path/to/libblis.a -lm
Please feel free to get back to us for any further clarifications or help.
