Hello, when compiling binutils-gdb I got stuck with an error concerning the strsignal function. This also occurs when trying to compile the insight gdb-frontend on cygwin64 that I tried to build.
* platform: o cygwin 64bit on Win-10 o gcc (GCC) 11.2.0, g++ (GCC) 11.2.0 * commands submitted: o git clone --recursive git://sourceware.org/git/binutils-gdb.git o autoconf o ./configure o make * Error message: o event-top.c: In function ‘void handle_fatal_signal(int)’: event-top.c:893:18: error: ‘strsignal’ was not declared in this scope; did you mean ‘strsigno’? 893 | sig_write (strsignal (sig)); * comment: o strsignal() is declared in string.h. However, including it doesn't work. Then I inspected string.h on cygwin64 in /usr/include and found this: o #ifndef DEFS_H /* Kludge to work around problem compiling in gdb */ char *strsignal (int __signo); #endif o suggestion: undefining DEFS_H might be risky -> to be added at line 55: + #ifndef DEFS_H # include <string.h> /* for strsignal on cygwin */ #else char *strsignal (int __signo); /* see /usr/include/string.h on cygwin */ #endif o then it compiles, however a library is missed now: + x86_64-pc-cygwin/bin/ld: event-top.o:.../insight/bundle/gdb/event-top.c:899: undefined reference to `strsignal(int)' collect2: error: ld returned 1 exit status Hope this helps somehow.
