vmware module rebuild fails with kernel-2.6.25-0.35.rc1.fc9.i686 (and gcc-c++-4.3.0-0.7.i386?).
The following code from <asm/page.h> compiles fine with gcc but not with g++:
typedef int pteval_t;
struct pte_t { pteval_t pte; int junk; };
typedef struct pte_t pte_t;
static inline pte_t native_make_pte(pteval_t val) { return (pte_t) { .pte = val }; }
[tbl@localhost ~]$ g++ -S t.c t.c: In function 'pte_t native_make_pte(pteval_t)': t.c:12: error: expected primary-expression before ')' token t.c:12: error: expected ';' before '{' token t.c:12: error: expected primary-expression before '.' token t.c:12: error: expected `;' before '}' token
Has 4.3 g++ changed the acceptability of the "designated initializer" in the return?
Changing the "dot =" to (obsolete?) "colon" appears acceptable:
static inline pte_t native_make_pte(pteval_t val) { return (pte_t) { pte:val }; }
There is a similar construct in <asm/paravirt.h> :
static inline pte_t __pte(pteval_t val) { pteval_t ret;
if (sizeof(pteval_t) > sizeof(long)) ret = PVOP_CALL2(pteval_t, pv_mmu_ops.make_pte, val, (u64)val >> 32); else ret = PVOP_CALL1(pteval_t, pv_mmu_ops.make_pte, val);
return (pte_t) { .pte = ret }; }
Changing to "colon" makes g++ happy.
This an issue with VMware? g++? headers? other?
