this is due to the test in build/pkgs/gmp/spkg-configure.m4
AX_ABSOLUTE_HEADER([gmp.h])
if test x$gl_cv_absolute_gmp_h = x; then
AC_MSG_ERROR(m4_normalize([
failed to find absolute path to gmp.h despite it being reported
found
]))
fi
AC_SUBST(SAGE_GMP_INCLUDE, [`AS_DIRNAME($gl_cv_absolute_gmp_h)`])
Replace this fragment with
AC_SUBST(SAGE_GMP_INCLUDE, [' '])
and re-run ./bootstrap
this will disable this check - I also assume that any package that
potentially needs
the correct value of SAGE_GMP_INCLUDE actually comes from Conda anyway, and so
this value, the absolute path to GMP include headers, is not relevant;
it can also be replaced with the value in question, say, /foo/bar, if
needed, by using instead
AC_SUBST(SAGE_GMP_INCLUDE, ['/foo/bar/'])
