Recent commit broke my windows build

32a527a

Using Visual Studio 2022 (17.11.5) I get the following build error. If I undo that commit it builds fine.

IMO, the commit 32a527a has no relation to the issue. It's probably e29f3d6. I don't have a Windows machine at hand. Please try tweaking lines in parse.y that are:.

#define YYSTACK_USE_ALLOCA 1
#define YYMALLOC
#define YYFREE

Changing 1 to 0 or removing some lines may stop errors and warnings. Please help us.

[jabamaus]

I'm sorry matz somehow I copied the wrong link. That is the commit I meant. If I remove the added #define YYMALLOC and
#define YYFREE the build error goes away.

[matz]

Thank you, if you remove YYMALLOC and YYFREE, you get warnings from VC, right?

OK, those warnings are harmless. Could you try removing YYSTACK_USE_ALLOCA line, please?

[jabamaus]

Without YYSTACK_USE_ALLOCA but still with YYMALLOC and YYFREE I get

Without any of those three lines it builds fine. What warnings were you trying to fix in the first place? Was it with VisualC?

[matz]

It was with VisualC. I was trying to resolve warnings mrbgems/mruby-compiler/core/y.tab.c(2290): warning C4273: 'malloc': inconsistent dll linkage and such.

So without any of the mentioned lines, you can compile mruby without any errors or warnings, right?

[jabamaus]

Only the removal of YYMALLOC and YYFREE is necessary for it to build.

If you give me the build command you were using I can have a look at the other warnings if you want.

[matz]

Let me confirm: You successfully compiled with YYSTACK_USE_ALLOCA 1 but without YYMALLOC and YYFREE defined, right?

[jabamaus]

Correct.

[jabamaus]

I wanted to look into this build issue a bit more as I was curious as to why I got different results to you CI. The reason for my build failure is that I set enable_cxx_exception to true. If I set that to false and use the original commit (ie YYMALLOC and YYFREE defined) I get these warnings:

CC mrbgems/mruby-compiler/core/y.tab.c -> build/host/mrbgems/mruby-compiler/core/y.tab.obj y.tab.c mrbgems/mruby-compiler/core/y.tab.c(6524): warning C4312: 'type cast': conversion from 'unsigned int' to 'yyalloc *' of greater sizemrbgems/mruby-compiler/core/y.tab.c(10760): warning C4312: 'type cast': conversion from 'unsigned int' to 'char *' of greater size mrbgems/mruby-compiler/core/keywords(58): warning C4267: 'initializing': conversion from 'size_t' to 'unsigned int', possible loss of data

However, these become errors if enable_cxx_exception is set to true (and a couple of new warnings):

CXX build/host/mrbc/mrbgems/mruby-compiler/core/y.tab-cxx.cxx -> build/host/mrbc/mrbgems/mruby-compiler/core/y.tab-cxx.obj y.tab-cxx.cxx C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(6364): warning C4065: switch statement contains 'default' but no 'case' labels C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(6524): error C2440: 'static_cast': cannot convert from 'unsigned int' to 'yyalloc *' C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(6524): note: Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or parenthesized function-style cast C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(10760): error C2440: 'static_cast': cannot convert from 'unsigned int' to 'char *' C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(10760): note: Conversion from integral type to pointer type requires reinterpret_cast, C-style cast or parenthesized function-style cast mrbgems/mruby-compiler/core/keywords(58): warning C4267: 'initializing': conversion from 'size_t' to 'unsigned int', possible loss of data rake aborted!

Its the cast that's the problem.

@jabamaus,
Could you solve it by adding #include <stdlib.h> to the mrbgems/mruby-compiler/core/parse.y file?
For example, make the following changes

diff --git a/mrbgems/mruby-compiler/core/parse.y b/mrbgems/mruby-compiler/core/parse.y
index 5a1605392..738f7c1e7 100644
--- a/mrbgems/mruby-compiler/core/parse.y
+++ b/mrbgems/mruby-compiler/core/parse.y
@@ -12,6 +12,7 @@
 #define YYSTACK_USE_ALLOCA 1

 #include <ctype.h>
+#include <stdlib.h>
 #include <string.h>
 #include <mruby.h>
 #include <mruby/compile.h>

I don't have a Windows environment either.
So I tried GitHub Actions and could not reproduce the error when setting conf.enable_cxx_abi or conf.enable_cxx_exception.
However, with the changes made, the warnings about malloc() and free() seem to have been resolved.

Hi dearblue, Adding stdlib.h doesn't break or make any difference to my build so go ahead. I'm still baffled why I see different warnings/errors, for example I see: C:/james_projects/GitHub/mruby_fork/mrbgems/mruby-compiler/core/y.tab.c(6363): warning C4065: switch statement contains 'default' but no 'case' labels I am using the exact same version of msvc - 17.11.5 x64. The only difference I can see is I'm using the Community Edition on Windows 10 and the CI is using the Enterprise Edition on Windows Server 2022. Could my build somehow have a higher warning level I wonder? Not sure how that could be the case either. Anyway, probably something to put into the background. Thanks for your help as always. James
