Created attachment 407068 [details, diff] patch for gcc-5.2.0 Similarly to https://bugs.gentoo.org/show_bug.cgi?id=554952 xf86-video-virtualbox-5.0.0 needs a patch for gcc-5.2.0 since the restriction to gcc version < 5.2 is not necessary. But there is an additional problem. It includes the current kernel headers directly. Unfortunately these contain the following declaration char *strreplace(char *s, char old, char new); in file include/linux/string.h But "new" is a keyword which is enforced with gcc-5.2.0 (at least) Therefore this include produces a syntax error. Since parameter names are redundant in a function's declaration (not its definition, of course), this declaration can be replaced by char *strreplace(char *s, char old, char NEW); Therefore one needs to patch the kernel headers as follows: --- include/linux/string.h 2015-06-27 16:44:41.218737227 +0200 +++ /usr/src/linux-4.2-rc2/include/linux/string.h 2015-07-15 10:15:28.603810671 +0200 @@ -111,7 +111,7 @@ extern void * memchr(const void *,int,__kernel_size_t); #endif void *memchr_inv(const void *s, int c, size_t n); -char *strreplace(char *s, char old, char new); +char *strreplace(char *s, char old, char NEW); extern void kfree_const(const void *x); Note that this patch has no effect besides disabling the syntax error described above.
Should be fixed with latest virtualbox-5 releases.
