Noteworthy changes in release 2015.02.04

Item posted by Peter Simons <simons> on Thu 05 Feb 2015 10:24:47 AM UTC.

AX_OPENMP: Test that we can actually #include <omp.h> successfully.

AX_COMPILER_FLAGS was re-factored into AX_COMPILER_FLAGS_CFLAGS and AX_COMPILER_FLAGS_LDFLAGS.

AX_CODE_COVERAGE detects gcov program.

AX_VALGRIND_CHECK now supports running without libtool.

AX_GCC_VERSION was improved.

Re-factored and modernized the macros AX_CXX_TEMPLATES, AX_CXX_CONST_CAST, AX_CXX_COMPLEX_MATH_IN_NAMESPACE_STD, AX_CXX_BOOL, AX_APPEND_FLAG, AX_CHECK_*_FLAG, AX_CHECK_ENABLE_DEBUG, and AX_CXX_DEFAULT_TEMPLATE_PARAMETERS.

AX_CXX_COMPILER_VENDOR was deprecated in favor of AX_COMPILER_VENDOR.

AX_HAVE_OPENGL was deprecated in favor of AX_CHECK_GL, AX_CHECK_GLU, AX_CHECK_GLUT, and AX_CHECK_GLX.

AX_CHECK_GL has a new parameter --with-mesa that allows choosing the order of opengl lib detection.

Portability of AX_LUA was improved. Support for LUA 5.0 was added.

New macros AX_IS_RELEASE, AX_COMPILER_FLAGS_GIR, AX_CXX_ERASE_ITERATOR_TYPE, AX_COMPILER_VERSION, AX_CHECK_GLX, AX_CHECK_VSCRIPT, AX_VALGRIND_CHECK, AX_PKG_CHECK_MODULES, and AX_COMPILER_FLAGS were added.

AX_PROG_FLEX: Also accept gflex.

AX_LIB_HDF5: remove extra leading space from include path flag. That space creeps into HDF5_CPPFLAGS and breaks the include path flag into two tokens, e.g., "-I" and "/usr/include". While this may be legal and doesn't affect the compilation, it does break some library tools (e.g., when the macro is used in building a dynamic library that uses pkg-config).

AX_PERL_MODULE_VERSION: use more portable syntax for shell arithmetic.

AX_JNI_INCLUDE_DIR: support standard Oracle JDK installation layout on Mac OS X.

AX_PROG_JAVAH_BIN_DIR: fix misspelled variable name and follow javah symlink to find jni.h.

AX_BOOST_PYTHON: use unique names for local variables
