firmware-utils: fix compilation on MacOS X
Looking into /usr/include/stdlib.h, there's a `devname()` function defined under some #ifdef's which conflicts with the `static char *devname` definition in `src/mkwrggimg.c`. Defining `_ANSI_SOURCE` in the `src/mkwrggimg.c` file, omits that part of the header. Another more intrusive approach is to rename `devname` to something like `g_devname` in `src/mkwrggimg.c`. But I think the `_ANSI_SOURCE` define should be enough. Compilation error is: src/mkwrggimg.c:64:14: error: redefinition of 'devname' as different kind of symbol static char *devname; ^ /usr/include/stdlib.h:286:7: note: previous definition is here char *devname(dev_t, mode_t); ^ src/mkwrggimg.c:147:12: error: non-object type 'char *(dev_t, mode_t)' (aka 'char *(int, unsigned short)') is not assignable devname = optarg; ~~~~~~~ ^ src/mkwrggimg.c:192:6: warning: comparison of function 'devname' equal to a null pointer is always false [-Wtautological-pointer-compare] if (devname == NULL) { ^~~~~~~ ~~~~ src/mkwrggimg.c:192:6: note: prefix with the address-of operator to silence this warning if (devname == NULL) { ^ & src/mkwrggimg.c:251:27: warning: incompatible pointer types passing 'char *(dev_t, mode_t)' (aka 'char *(int, unsigned short)') to parameter of type 'const char *' [-Wincompatible-pointer-types] strncpy(header->devname, devname, sizeof(header->devname)); ^~~~~~~ /usr/include/secure/_string.h:119:34: note: expanded from macro 'strncpy' __builtin___strncpy_chk (dest, src, len, __darwin_obsz (dest)) Signed-off-by: Alexandru Ardelean <ardeleanalex@gmail.com> [Jo-Philipp Wich: slightly reformat commit message] Signed-off-by: Jo-Philipp Wich <jo@mein.io>
