acinclude: autoconf macros

NAME

acinclude - autoconf macros
DESCRIPTION
These macros test for particular system featutres that rheolef uses. These tests print the messages telling the user which feature they are looking for and what they find. They cache their results for future configure runs. Some of these macros set some shell variable, defines some output variables for the 'config.h' header, or performs Makefile macros subsitutions. See autoconf documentation for how to use such variables.
SYNOPSIS
Follows a list of particular check required for a successfull installation. RHEO_CHECK_GINAC Check to see if GiNaC library exists. If so, set the shell variable rheo_have_ginac to "yes", defines HAVE_GINAC and substitues INCLUDES_GINAC and LADD_GINAC for adding in CFLAGS and LDFLAGS, respectively, If not, set the shell variable rheo_have_ginac to "no".

Set also LIBS_MALLOC_DBG to these flags. RHEO_CHECK_DMALLOC Check whether the dmalloc package exists and set the corresponding shell value "rheo_have_dmalloc" and HAVE_DMALLOC (in Makefile.am and config.h) accordingly, create LDADD_DMALLOC and LDADD_DMALLOCXX Makefile.am variables. RHEO_CHECK_NAMESPACE Check whether the namespace feature is supported by the C++ compiler. value. So, try to compile the following code: namespace computers { struct keyboard { int getkey() const { return 0; } }; } namespace music { struct keyboard { void playNote(int note); }; } namespace music { void keyboard::playNote(int note) { } } using namespace computers; int main() { keyboard x; int z = x.getkey(); music::keyboard y; y.playNote(z); return 0; } If it compile, set the corresponding shell variable "rheo_have_namespace" to "yes" and defines HAVE_NAMESPACE. If not, set the variable no "no". RHEO_CHECK_STD_NAMESPACE Some compilers (e.g. GNU C++ 2.7.2) does not support the full namespace feature. Nevertheless, they support the "std:" namespace for the C++ library. is supported by the C++ compiler. The following code is submitted to the compiler: #include<vector.h> extern "C" void exit(int); int main() { std::vector<int> x(3); return 0; } If it compile, set the corresponding shell variable "rheo_have_std_namespace" to "yes" and defines HAVE_STD_NAMESPACE. If not, set the variable no "no". RHEO_PROG_GNU_MAKE Find command make and check whether make is GNU make. If so, set the corresponding shell variable "rheo_prog_gnu_make" to "yes" and substitues no_print_directory_option to "--no-print-directory". If not, set the shell variable no "no". RHEO_CHECK_ISTREAM_RDBUF RHEO_CHECK_IOS_BP Check to see if "iostream::rdbuf(void*)" function exists, that set the "ios" buffer of a stream. Despite this function is standard, numerous compilers does not furnish it. a common implementation is to set directly the buffer variable. For instance, the CRAY C++ compiler implements this variable as "ios::bp". These two functions set the shell variables "rheo_have_istream_rdbuf" and "rheo_have_ios_bp" and define HAVE_ISTREAM_RDBUF and HAVE_IOS_BP respectively. RHEO_CHECK_IOS_SETSTATE Check to see if "ios::setstate(long)" function exists, that set the "ios" state variable of a stream. Despite this function is standard, numerous compilers does not furnish it. a common implementation is to set directly the buffer variable. For instance, the CRAY C++ compiler does not implements it. This function set the shell variables "rheo_have_ios_setstate" and define HAVE_IOS_SETSTATE. RHEO_CHECK_FILEBUF_INT RHEO_CHECK_FILEBUF_FILE RHEO_CHECK_FILEBUF_FILE_MODE Check wheter "filebuf::filebuf(int fileno)", "filebuf::filebuf(FILE* fd)" exist, or "filebuf::filebuf(FILE* fd, ios::openmode)" exist, respectively.

Check whether the "gettimeofday(timeval*)" function exists and set the corresponding shell value "rheo_have_wierdgettimeofday" and define HAVE_WIERDGETTIMEOFDAY accordingly. RHEO_CHECK_BSDGETTIMEOFDAY For BSD systems, check whether the "BSDgettimeofday(timeval*, timezone*)" function exists and set the corresponding shell value "rheo_have_bsdgettimeofday" and define HAVE_BSDGETTIMEOFDAY accordingly. RHEO_CHECK_AMICCLK Check whether the clock "amicclk()" function exists and set the corresponding shell value "rheo_have_amicclk" and define HAVE_AMICCLK accordingly. RHEO_CHECK_TEMPLATE_FULL_SPECIALIZATION Check whether the template specialization syntax "template<>" is supported by the compiler value. So, try to compile, run and check the return value for the following code: template<class T> struct toto { int tutu() const { return 1; } }; template<> struct toto<float> { int tutu() const { return 0; } }; main() { toto<float> x; return x.tutu(); } If so, set the corresponding shell variable "rheo_have_template_full_specialization" to "yes" and defines HAVE_TEMPLATE_FULL_SPECIALIZATION.

If so, set the corresponding shell variable "rheo_have_xxx" to "yes" and defines HAVE_XXX. If not, set the variable no "no". RHEO_CHECK_FLEX Check to see if the "flex" command and the corresponding header "FlexLexer.h" are available. If so, set the shell variable "rheo_have_flex" to "yes" and substitues FLEX to "flex" and FLEXLEXER_H to the full path for FlexLexer.h If not, set the shell variable no "no". RHEO_PROG_CC_KAI Check wheter we are using KAI C++ compiler. If so, set the shell variable "ac_cv_prog_kcc" to "yes". If not, set the shell variable no "no". The shell variable is also exported for sub-shells, such as ltconfig from libtool. RHEO_PROG_CC_CRAY Check wheter we are using CRAY C++ compiler. If so, set the shell variable "ac_cv_prog_cray_cc" to "yes" and defines HAVE_CRAY_CXX. If not, set the shell variable no "no". The shell variable is also exported for sub-shells.

The shell variable is also exported for sub-shells, such as ltconfig from libtool. RHEO_RECOGNIZE_CXX Check wheter we are able to recognize the C++ compiler. Tested compilers: The KAI C++ compiler that defines: __KCC (KCC-3.2b) The GNU C++ compiler that defines: __GNUC__ (egcs-1.1.1) The CRAY C++ compiler that defines: cray The DEC C++ compiler that defines: __DECCXX If so, substitue RECOGNIZED_CXX to a specific compiler's rule file, e.g, {}"$top_srcdir/config/gnu_cxx.mk", for a subsequent Makefile include. If not, substitue to "/dev/null". Substitutes also EXTRA_LDFLAGS. Raw cc is the C compiler associated to the C++ one. By this way C and C++ files are handled with a .c suffix. Special C files that requiere the cc compiler, such as "alloca.c" use some specific makefile rule. usage example: AC_PROG_CC(gcc cc cl) AC_PROG_CXX(c++ g++ cxx KCC CC CC cc++ xlC aCC) RHEO_RECOGNIZE_CXX RHEO_OPTIMIZE_CXX Set some optimization flags associated to the recognized C++ compiler and platform.
