65a847cd36 Introduce openblas_get_num_threads and openblas_get_num_procs 2015-02-03 12:23:41 -05:00

0b4602b753 add SYMBOLPREFIX and SYMBOLSUFFIX makefile options 
for adding a prefix or suffix to all exported symbol names in the shared library
Useful to avoid conflicts with other BLAS libraries, especially when using
64 bit integer interfaces in OpenBLAS

Note that since OSX does not have the objcopy utility, setting these options
to non-empty values on Mac requires the objconv tool, available (GPL license)
from http://www.agner.org/optimize/#objconv

c6361d63c2 Add -lgfortran flag to gcc call in a makefile 
Adding $(EXTRALIB) adds this flag when things are built with
msys2 on windows. Without this the build fails.

ce5626a384 Remove -Wl,--retain-symbols-file from dynamic library linking to fix tool support 
The aim is to restrict the symbols exported from openBLAS, but for dynamic libraries --retain-symbols-file has the opposite effect intended. It removes symbols from the .symtab section of the library, which is used by tools such as debuggers, profilers, objdump etc. but does not remove them from .dynsym, which is the section used by the runtime when loading the binary.

In short, using --retain-symbols-file like this doesn't prevent symbol leakage but does prevent tools from analyzing applications linked with openBLAS.

This patch improves tool support for openBLAS applications but does not address symbol leakage through .dynsym.

c92ae012a6 Refs #279. Provide ONLY_CBLAS flag. If you only need CBLAS without 
a fortran compiler, please try make ONLY_CBLAS=1.

This mode only compiler CBLAS without BLAS fortran interface and LAPACK.

bdf8d9411e Refs #163. Obtain the build configure on runtime. 
openblas_get_config function returns the configure string.
So far, it supports USE64BITINT, NO_CBLAS, NO_LAPACK, NO_LAPACKE,
DYNAMIC_ARCH, NO_AFFINITY.

Example:
 #include <stdio.h>
extern char * openblas_get_config();
void main()
{
  printf("%s\n",openblas_get_config());
  return;
}
