OK, sorry. Here's another try "hand-edited". Lines should be easy enough to
find hopefully.
===== 1st error =====
sqlite3.c(17654): error #265: floating-point operation result is out of
range
// around line 17644
- result = 1e308*1e308*s; /* Infinity */
+ result = 1e308*(1e308*s); /* Infinity */
===== 2nd error =====
sqlite3.c.o:sqlite3.c:function sqlite3VdbeExec.h: error: undefined
reference to '__builtin_add_overflow', etc...
SQLITE_PRIVATE int sqlite3AddInt64(i64 *pA, i64 iB){
- #if GCC_VERSION>=5004000
+#if GCC_VERSION>=5004000 && !defined(__INTEL_COMPILER)
return __builtin_add_overflow(*pA, iB, pA);
#else
SQLITE_PRIVATE int sqlite3SubInt64(i64 *pA, i64 iB){
- #if GCC_VERSION>=5004000
+#if GCC_VERSION>=5004000 && !defined(__INTEL_COMPILER)
return __builtin_sub_overflow(*pA, iB, pA);
#else
SQLITE_PRIVATE int sqlite3MulInt64(i64 *pA, i64 iB){
- #if GCC_VERSION>=5004000
+ #if GCC_VERSION>=5004000 && !defined(__INTEL_COMPILER)
return __builtin_mul_overflow(*pA, iB, pA);
#else
Please note that I'm not saying this is the best fix.
A colleague made those changes to make it build.
It wasn't necessary with Intel 15. --DD
