The following commands give me different results on 2.1.2 and 2.1.3.

  make dynamic
  export LD_LIBRARY_PATH="$LD_LIBRARY_PATH:$OUTDIR/lib64"
  make

In 2.1.2 and earlier, the resulting compiler options are typically:

  -c  -DNDEBUG  -m64    -D_LOGGING -D_ARCH_BITS=64 -DLINUX -DUNIX -D_GNU_SOURCE
  -D_REENTRANT -D_FILE_OFFSET_BITS=64 -I/tmp/sra_sdk-2.1.2/libs/klib/linux
  -I/tmp/sra_sdk-2.1.2/libs/klib/unix -I/tmp/sra_sdk-2.1.2/libs/klib
  -I/tmp/sra_sdk-2.1.2/interfaces -I/tmp/sra_sdk-2.1.2/interfaces/cc/gcc/x86_64
  -I/tmp/sra_sdk-2.1.2/interfaces/cc/gcc -I/tmp/sra_sdk-2.1.2/interfaces/os/linux
  -I/tmp/sra_sdk-2.1.2/interfaces/os/unix -I/tmp/sra_sdk-2.1.2/interfaces/ext -MD
  -fPIC -O3 -fno-strict-aliasing -D_LIBRARY

While in 2.1.3 and later they are:

  -c  -DNDEBUG  -m64   -D_STATIC -DLINUX -DUNIX -D_GNU_SOURCE -D_REENTRANT
  -D_FILE_OFFSET_BITS=64 -D_ARCH_BITS=64 -DLIBPREFIX=lib -DSHLIBEXT=so
  -I/tmp/sra_sdk-2.1.3/libs/klib/linux -I/tmp/sra_sdk-2.1.3/libs/klib/unix
  -I/tmp/sra_sdk-2.1.3/libs/klib -I/tmp/sra_sdk-2.1.3/interfaces
  -I/tmp/sra_sdk-2.1.3/interfaces/cc/gcc/x86_64
  -I/tmp/sra_sdk-2.1.3/interfaces/cc/gcc -I/tmp/sra_sdk-2.1.3/interfaces/os/linux
  -I/tmp/sra_sdk-2.1.3/interfaces/os/unix -I/tmp/sra_sdk-2.1.3/interfaces/ext -MD
  -fPIC -O3 -fno-strict-aliasing -D_LIBRARY

Accordingly, the build in 2.1.3 is static, as witnessed by the absence of files
in <OUTDIR>/mod64/.

Best,
