Thanks for your kind response. Rhe package in question is gsl ( http://www.gnu.org/software/gsl/ ) and the platform is linux; compiler gcc I have generated a config.h of sorts ( I was looking at the wrong source directory. build.h is there alright as an integral part thereof). CMake did generate Makefiles and a config.h. The make fails not long after starting with the following:- ########### ~/sys/infnan.c:98:3: error: #error "cannot define gsl_finite without HAVE_DECL_FINITE or HAVE_IEEE_COMPARISONS" ~/sys/infnan.c:115:3: error: #error "cannot define gsl_isnan without HAVE_DECL_ISNAN or HAVE_IEEE_COMPARISONS" ########## The problem seems to revolve around the scope/ of the functions used to mimic the config.h (aoto-tools). :- ----------------Here is the relevant configure output checking for ieeefp.h... no checking for vprintf... yes checking for _doprnt... no checking for memcpy... yes checking for memmove... yes checking for strdup... yes checking for strtol... yes checking for strtoul... yes checking for EXIT_SUCCESS and EXIT_FAILURE... yes checking for cos in -lm... yes checking whether feenableexcept is declared... yes checking whether fesettrapenable is declared... no checking whether hypot is declared... yes checking whether expm1 is declared... yes checking whether acosh is declared... yes checking whether asinh is declared... yes checking whether atanh is declared... yes checking whether ldexp is declared... yes checking whether frexp is declared... yes checking whether isinf is declared... yes checking whether isfinite is declared... yes checking whether finite is declared... yes checking whether isnan is declared... yes checking whether log1p is declared... yes checking for long double stdio... yes checking for extended floating point registers... yes checking for IEEE arithmetic interface type... gnux86 checking for FPU_SETCW... yes checking for SSE extensions... yes checking for IEEE compiler flags... none checking for IEEE comparisons... yes checking for IEEE denormalized values... yes ------------------ and the relevant section from config.log configure:11068: checking whether hypot is declared configure:11068: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11068: $? = 0 configure:11068: result: yes configure:11080: checking whether expm1 is declared configure:11080: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11080: $? = 0 configure:11080: result: yes configure:11092: checking whether acosh is declared configure:11092: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11092: $? = 0 configure:11092: result: yes configure:11104: checking whether asinh is declared configure:11104: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11104: $? = 0 configure:11104: result: yes configure:11116: checking whether atanh is declared configure:11116: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11116: $? = 0 configure:11116: result: yes configure:11128: checking whether ldexp is declared configure:11128: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11128: $? = 0 configure:11128: result: yes configure:11140: checking whether frexp is declared configure:11140: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11140: $? = 0 configure:11140: result: yes configure:11152: checking whether isinf is declared configure:11152: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11152: $? = 0 configure:11152: result: yes configure:11164: checking whether isfinite is declared configure:11164: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11164: $? = 0 configure:11164: result: yes configure:11176: checking whether finite is declared configure:11176: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11176: $? = 0 configure:11176: result: yes configure:11191: checking whether isnan is declared configure:11191: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11191: $? = 0 configure:11191: result: yes configure:11210: checking whether log1p is declared configure:11210: gcc -c -O3 -fexceptions -m64 -fPIC conftest.c >&5 configure:11210: $? = 0 configure:11210: result: yes -------------and here it is in cmake (using the config.h.cmake (below) -- Looking for dlfcn.h -- Looking for dlfcn.h -
