[openssl.org #3556] Problem building openssl 1.0.1i in debug mode

[Dmitry Belyavsky via RT]

Hello openssl team,

I've got a problem building openssl

I used the commands

./Configure shared debug
make

and get an error

gcc -I.. -I../.. -I../modes -I../asn1 -I../evp -I../../include -DBN_DEBUG
-DREF_CHECK -DCONF_DEBUG -DBN_CTX_DEBUG -DCRYPTO_MDEBUG -DOPENSSL_NO_ASM
-ggdb -g2 -Wformat -Wshadow -Wmissing-prototypes -Wmissing-declarations
-Werror -c -o bn_ctx.o bn_ctx.c
bn_ctx.c: In function ‘ctxdbg’:
bn_ctx.c:161:29: error: cast from pointer to integer of different size

Thank you

In crypto/bn/bn_ctx.c, line 161:
fprintf(stderr,"(%08x): ", (unsigned int)ctx);
change it to this
fprintf(stderr,"(%p): ", ctx);

and see if that fixes it.

Hello Rich,

Unfortunately no :-(
The error became

bn_ctx.c: In function ‘ctxdbg’:
bn_ctx.c:161:27: error: cast from pointer to integer of different size
[-Werror=pointer-to-int-cast]
bn_ctx.c:161:2: error: format ‘%p’ expects argument of type ‘void *’, but
argument 3 has type ‘unsigned int’ [-Werror=format]
cc1: all warnings being treated as errors

Post by Salz, Rich
fprintf(stderr,"(%08x): ", (unsigned int)ctx);
change it to this
fprintf(stderr,"(%p): ", ctx);
and see if that fixes it.

Did you take the (unsigned int) cast off?

Do sed –n –e 160,162p bn_ctx.

Hello Rich,

Yes, removing the cast solves the problem.

***@manul$ sed -n -e 160,162p crypto/bn/bn_ctx.c
BN_STACK *stack = &ctx->stack;
fprintf(stderr,"(%p): ", ctx);
while(bnidx < ctx->used)


Thank you!

I used the commands
./Configure shared debug

^^^^^^^^^^^^^^^^^^^^^^^^ I don't think this would be working build on
a 64-bit platform such as one in question. Or rather even if it does
work (make test passes, etc.) it wouldn't be supported and questions
should be dismissed. "Official" way to make a debugging build is to pass
-d to ./config.
