Hi. I've been building screen 4.0.3 for Cygwin 1.5 for several years now. Now Cygwin 1.7 is out, and it appears that the Cygwin API has changed, because I'm getting some build errors.
Can someone please advise what's the simplest or best way to correct for these? (1) The build fails with extern.h:149: error: conflicting types for 'execvpe' Indeed Cygwin's /usr/include/unistd.h has int _EXFUN(execvpe, (const char *__file, char * const __argv[], char *const __envp[] )); while extern.h has extern void execvpe __P((char *, char **, char **)); execvpe() is defined in window.c:1387, so screen has its own private implementation, apparently now incompatible with Cygwin's. (2) Similarly, I get warnings about incompatible implicit declarations of strlen, strcpy, and strncpy, e.g. screen.c: In function 'main': screen.c:473: warning: incompatible implicit declaration of built-in function 'strcpy' screen.c:642: warning: incompatible implicit declaration of built-in function 'strlen' /usr/include/string.h has size_t _EXFUN(strlen,(const char *)); char *_EXFUN(strcpy,(char *, const char *)); char *_EXFUN(strncpy,(char *, const char *, size_t)); I'm not sure what's wrong with this, since the function calls that are triggering the warnings are just e.g. (screen.c:473) strcpy(screenterm, "screen"); (screen.c:642) if (strlen(*++av) < 20) where screenterm and av are of the right types. I'm also not sure what "built-in function 'strcpy'" means-- built into what? Does this mean that the compiler is using a different version of strlen() et al. than the one in string.h? Thanks, Andrew. _______________________________________________ screen-users mailing list screen-users@gnu.org http://lists.gnu.org/mailman/listinfo/screen-users
