Subject Cross-MinGW linking problem
Date Mon, 08 Apr 2013 10:48:19 GMT
Hi, every body.

I was just tring to build Proton (svn1465587) with MinGW on Fedora
cross-compiling environment[1].

When linking libqpid-proton.dll, I found libqpid-proton.dll.a is missing
symbols available in the dll.

The linking command:
/usr/bin/i686-w64-mingw32-gcc   -Wl,--no-undefined   -shared -o
libqpid-proton.dll -Wl,--out-implib,libqpid-proton.dll.a
-Wl,--major-image-version,1,--minor-image-version,0 -Wl,--whole-archive
CMakeFiles/qpid-proton.dir/objects.a -Wl,--no-whole-archive -lws2_32
-lrpcrt4 -L. -lkernel32 -luser32 -lgdi32 -lwinspool -lshell32 -lole32
-loleaut32 -luuid -lcomdlg32 -ladvapi32

Output of 'i686-w64-mingw32-nm objects.a' in qpid-proton.dir:
http://cheeselee.fedorapeople.org/nm-qpid-proton-objects.a.txt

Output of 'i686-w64-mingw32-nm libqpid-proton.dll':
http://cheeselee.fedorapeople.org/nm-libqpid-proton.dll.txt

Output of 'i686-w64-mingw32-nm libqpid-proton.dll.a':
http://cheeselee.fedorapeople.org/nm-libqpid-proton.dll.a.txt

The successive result is proton.exe failed to link, since
libqpid-proton.dll.a is missing symbols.

0.4 stable also suffer this problem.

Native Linux Build is smooth.
