libgpg-error : code-from-errno.h not correctly generated when cross-compiling to Windows on Linux

Hey,

I'm trying to compile libgpg-error for Windows 64 bits with mingw-w64. I
cross compile it on linux (ubuntu).

configuration: ./configure --prefix=/opt/efl --host=x86_64-w64-mingw32
--disable-nls --disable-static

generation of the files:

make[3]: Entering directory
`/home/torri/gitroot/packages/packages/MinGW/libgpg-error-1.10-src/release/mingw-w64-x86_64-libgpg-error-1.10/src'
gawk -f ./mkerrnos.awk ./errnos.in >code-to-errno.h
gawk -f ./mkerrcodes1.awk ./errnos.in >_mkerrcodes.h
gawk -f ./mkstrtable.awk -v textidx=2 -v nogettext=1 \
./err-sources.h.in >err-sources-sym.h
gawk -f ./mkstrtable.awk -v textidx=2 -v nogettext=1 \
./err-codes.h.in >err-codes-sym.h
x86_64-w64-mingw32-gcc -E _mkerrcodes.h | grep GPG_ERR_ | \
gawk -f ./mkerrcodes.awk >mkerrcodes.h
gawk -f ./mkstrtable.awk -v textidx=2 -v nogettext=1 \
-v prefix=GPG_ERR_ -v namespace=errnos_ \
./errnos.in >errnos-sym.h
rm extra-h.in
rm: cannot remove `extra-h.in': No such file or directory
make[3]: [extra-h.in] Error 1 (ignored)
cat ./w32-add.h >>extra-h.in
cat ./gpg-error.def.in >_gpg-error.def.h
echo EOF >>extra-h.in
x86_64-w64-mingw32-gcc -E -I. -I.. _gpg-error.def.h | \
grep -v '^#' >gpg-error.def
echo "/*dummy*/" > mkw32errmap.map.c
rm _gpg-error.def.h
gawk -f ./mkheader.awk \
./err-sources.h.in \
./err-codes.h.in \
./errnos.in \
extra-h.in \
./gpg-error.h.in > gpg-error.h
rm _mkerrcodes.h
cc -I. -I. -o mkerrcodes ./mkerrcodes.c
./mkerrcodes | gawk -f ./mkerrcodes2.awk >code-from-errno.h
make all-am

Here is the beginning of code-from-errno.h :

-2147168224 GPG_ERR_EPROTO
static const int err_code_from_index[] = {
GPG_ERR_EPERM,
etc....

So if someone has an idea of the fix....

thank you

Use

./autogen.sh --build-w64

to build it. Some time ago I changed a few things and was then able to
build a pure 64 bit version which worked without problems on
Windows7-64bit. You need master of course.

libgpg-error is the only module which has support for 64 bit Windows.

i'll try with the git repo, then.

Actually, I need libgcrypt for crypto in gnutls. So it means that,
currently, it's useless to try to compile libgcrypt for win64 ?

I actually have the same problem when cross compiling to win32 :

configuration : ./configure --prefix=/opt/efl --host=i686-w64-mingw32
--disable-nls --disable-static

exactly the same problem

Don't use it. We do not have an RNG for w64.

I thought windows has a PRNG suited for cryptography bundled. Why can't you
use that?

Just lookin at the output of ./mkerrcodes, I get:

-2147168224 GPG_ERR_EPROTO
1 GPG_ERR_EPERM
2 GPG_ERR_ENOENT
etc...

So it seems that there is a problem with the fact that GPG_ERR_EPROTO is
negative (i think). So integer size overflow.

I changed mkerrcodes.c so that it displays an unsigned int. The 2 changes
lines are:

unsigned int i;
...
printf ("%u\t%s\n", err_table[i].err, err_table[i].err_sym);

and it works now.

regards

Vincent

that change is not necessary, of course, but as i >= 0 anyway...
