From 84d32bf7678259c08406571cd6ce4b7a6724dcba Mon Sep 17 00:00:00 2001 From: Ramsay Jones Date: Sat, 27 Apr 2013 20:19:47 +0100 Subject: sparse: Fix mingw_main() argument number/type errors Sparse issues 68 errors (two errors for each main() function) such as the following: SP git.c git.c:510:5: error: too many arguments for function mingw_main git.c:510:5: error: symbol 'mingw_main' redeclared with different type \ (originally declared at git.c:510) - different argument counts The errors are caused by the 'main' macro used by the MinGW build to provide a replacement main() function. The original main function is effectively renamed to 'mingw_main' and is called from the new main function. The replacement main is used to execute certain actions common to all git programs on MinGW (e.g. ensure the standard I/O streams are in binary mode). In order to suppress the errors, we change the macro to include the parameters in the declaration of the mingw_main function. Unfortunately, this change provokes both sparse and gcc to complain about 9 calls to mingw_main(), such as the following: CC git.o git.c: In function 'main': git.c:510: warning: passing argument 2 of 'mingw_main' from \ incompatible pointer type git.c:510: note: expected 'const char **' but argument is of \ type 'char **' In order to suppress these warnings, since both of the main functions need to be declared with the same prototype, we change the declaration of the 9 main functions, thus: int main(int argc, char **argv) Signed-off-by: Ramsay Jones Signed-off-by: Junio C Hamano --- test-index-version.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'test-index-version.c') diff --git a/test-index-version.c b/test-index-version.c index bfaad9e09..05d4699c4 100644 --- a/test-index-version.c +++ b/test-index-version.c @@ -1,6 +1,6 @@ #include "cache.h" -int main(int argc, const char **argv) +int main(int argc, char **argv) { struct cache_header hdr; int version; -- cgit v1.2.1
