Guys Sorry for bothering the list for my issues. I am trying to port User Mode Linux. I am just at the beginning stages. I downloaded the latest Linux version and started hacking it. After making several code modifications, I am able to fully compile the source code. Now I am only able to create the executable using MSYS2 ld. Using CUGWIN I get several undefined references. All the reference symbols are WEAK external symbols.
Now, in MSYS2 I am using binutils 2.26. This version has a WEAK NT external patch (https://sourceware.org/ml/binutils/2015-10/msg00234.html). My version in CYGWIN is 2.25.2. So, I tried to compile the latest version of binutils 2.28. That fails to compile with the following error In file included from plural.y:35:0: plural-exp.h:102:23: error: conflicting types for ‘libintl_gettextparse’ # define PLURAL_PARSE libintl_gettextparse ^ plural.y:40:25: note: in expansion of macro ‘PLURAL_PARSE’ # define __gettextparse PLURAL_PARSE ^~~~~~~~~~~~ plural.c:182:5: note: in expansion of macro ‘__gettextparse’ int __gettextparse (void); ^~~~~~~~~~~~~~ plural-exp.h:102:23: note: previous declaration of ‘libintl_gettextparse’ was here # define PLURAL_PARSE libintl_gettextparse ^ plural-exp.h:114:12: note: in expansion of macro ‘PLURAL_PARSE’ extern int PLURAL_PARSE PARAMS ((void *arg)); ^~~~~~~~~~~~ plural-exp.h:102:23: error: conflicting types for ‘libintl_gettextparse’ # define PLURAL_PARSE libintl_gettextparse ^ plural.y:40:25: note: in expansion of macro ‘PLURAL_PARSE’ # define __gettextparse PLURAL_PARSE ^~~~~~~~~~~~ plural.c:63:25: note: in expansion of macro ‘__gettextparse’ #define yyparse __gettextparse ^~~~~~~~~~~~~~ plural.c:1127:1: note: in expansion of macro ‘yyparse’ yyparse (void) ^~~~~~~ plural-exp.h:102:23: note: previous declaration of ‘libintl_gettextparse’ was here # define PLURAL_PARSE libintl_gettextparse ^ plural-exp.h:114:12: note: in expansion of macro ‘PLURAL_PARSE’ extern int PLURAL_PARSE PARAMS ((void *arg)); ^~~~~~~~~~~~ plural.c: In function ‘libintl_gettextparse’: plural.c:64:25: error: too few arguments to function ‘__gettextlex’ #define yylex __gettextlex ^ plural.c:1296:16: note: in expansion of macro ‘yylex’ yychar = yylex (&yylval); ^~~~~ plural.c:64:25: note: declared here #define yylex __gettextlex ^ plural.y:69:12: note: in expansion of macro ‘yylex’ static int yylex PARAMS ((YYSTYPE *lval, const char **pexp)); ^~~~~ plural.y:178:29: error: ‘arg’ undeclared (first use in this function) ((struct parse_args *) arg)->res = $1; ^~~ plural.y:178:29: note: each undeclared identifier is reported only once for each function it appears in make[2]: *** [Makefile:133: plural.o] Error 1 make[2]: Leaving directory '/cygdrive/e/dev/GitHub/gnu/binutils-gdb/intl' make[1]: *** [Makefile:6570: all-intl] Error 2 make[1]: Leaving directory '/cygdrive/e/dev/GitHub/gnu/binutils-gdb' make: *** [Makefile:853: all] Error 2 Now, I go back an use the linker from MSYS2 and generate the executable for Cygwin. When I run the executable, it runs very quickly and returns. I debugging using gdb and I see a CFE somewhere inside cygtls:call. I have tried many things to investigate why this is happening, but I have been unable to get to the bottom of the problem. I am thinking that this could be due to the use of LDS scripts to generate the executable, but I really have no real clue that this could be true. I also generated the executable by hand from the vmlinux image using the command gcc -Wl,--wrap,malloc -Wl,--wrap,free -Wl,--wrap,calloc -mcmodel=large -Wl,--export-all-symbols -Wl,--enable-auto-import -o linux.exe vmlinux -lws2_32 That still produce the same result. So, can someone help me diagnose this problem better and address it, please? I am your guinea pig.
