pgbouncer 1.7.0 fails to cross-compile with mingw-w64

[tkren]

Cross-compiling pgbouncer 1.7.0 fails with the following setup:

• Debian jessie installation of mingw-w64 3.2.0-2
• libevent 2.0.22 cross-compiled to $HOME/mingw64
• openssl 1.0.1g cross-compiled to $HOME/mingw64

After configuring pgbouncer with

./configure --host=x86_64-w64-mingw32 --enable-evdns --disable-debug --with-libevent=$HOME/mingw64 --with-openssl=$HOME/mingw64

make fails with

[...]

The issue is with libusual. I hacked together a quick and dirty patch to get it to compile, seems to work ok so far. I also had to set LDFLAGS =-mwindows to avoid linker errors.

usual.patch.txt

[tkren]

the patch fixes the arpa/inet.h problem, but it seems that there is still something missing:

[...]

lib/usual/tls/tls_client.c: In function ‘tls_connect_servername’:
lib/usual/tls/tls_client.c:110:21: error: ‘AI_ADDRCONFIG’ undeclared (first use in this function)
    hints.ai_flags = AI_ADDRCONFIG;
                     ^

[chenz]

Ah yes, I forgot - for AI_ADDRCONFIG to be defined, the Windows API version must be set to "Vista".

env LDFLAGS=-mwindows CPPFLAGS=-D_WIN32_WINNT=0x0600 ./configure --prefix=... --host=x86_64-w64-mingw32 --with-libevent=... --with-openssl=...

[tkren]

thank you for your help, this seems to work.

Hi,
I'm trying to build pgbouncer-1.7 on Windows server 2012 R2 with MINGW 32. I have faced the same issue " fatal error: arpa/inet.h: No such file or directory " as like mentioned in before thread. After applied your patch "usual.patch.txt", this issue seems to resolved.

Later I got the below make error even though configure pgbounce as like below
LDFLAGS=-mwindows CPPFLAGS=-D_WIN32_WINNT=0x0600 ./configure --prefix=... --with-libevent=... --with-openssl=...set to

lib/usual/tls/tls_client.c: In function tls_connect_servername': lib/usual/tls/tls_client.c:110: error:AI_ADDRCONFIG' undeclared (first use in this function)
lib/usual/tls/tls_client.c:110: error: (Each undeclared identifier is reported only once
lib/usual/tls/tls_client.c:110: error: for each function it appears in.)
make: *** [.objs/pgbouncer/lib/usual/tls/tls_client.o] Error 1

Can you please advice , how we can resolve this issue.

[chenz]

Maybe an issue with the shell? Maybe try setting the environment variables separately

set LDFLAGS=...
set CPPFLAGS=...
./configure ...

Hi,

Thanks for your response. To fix the above error , I had to define AI_ADDRCONFIG in my Mingw installation header file ( MinGW/include/ws2tcpip.h ). But after this I got again below build error.

objs/pgbouncer/lib/usual/string.o: In function usual_strpcat': pgbouncer/lib/usual/string.c:233: undefined reference tostrnlen'
.objs/pgbouncer/lib/usual/time.o: In function usual_timegm': pgbouncer/lib/usual/time.c:187: undefined reference to_mkgmtime'
collect2: ld returned 1 exit status
make: *** [pgbouncer.exe] Error 1

So here I tried to search for strnlen keyword in my Mingw header files but I didn't get any such keyword. At the same time I can found strlen but not strnlen. That means strnlen is not supported by MinGW version 3.14 .

Can you please suggest me how can I over come above issue.

Current master seems to build for me with mingw-w64-dev 2.0.1-1 and configured with

LIBS="-lgdi32" \
./configure --host=x86_64-w64-mingw32 \
  --without-cares \
  --with-libevent=/opt/apps/win64 \
  --with-openssl=/opt/apps/win64 \
  --enable-evdns

-lgdi is because of static openssl.

So problems with _mkgmtime and strnlen are caused by something else.

Hi,
Can you please grep for stnlen() in your MInGW installation header files and let me know resulted files.I found the thread related to strnlen is not included in the official builds of MinGW. https://sourceforge.net/p/mingw/bugs/1912/

[markokr]

Actually, configure already checks for strnlen and libusual should replace it if not found. So it seems in your case configure did find it but linker does not...

Do you have HAVE_STRNLEN defined in your config.h?

[chenz]

It seems this and the missing AI_ADDRCONFIG definition is due to murali05 using (obsolete?) mingw32, whereas everyone else here uses mingw-w64.

Closing. Compiles-for-me.
