SOLVED: Compilation on cygwin - Problems with missing symbols in vmime

marlemion

Hi! Based on this post: https://forum.kopano.io/topic/2526/kopano-core-python-libraries-on-windows I am trying since a few days now to compile kopano-core on cygwin. Cygwin provides nearly all of the dependencies. I just had to compile and package libHX, gSOAP and, well, vmime.

Vmime has been taken from the kopano git in Version 0.9.2. The kopano-core version to compile is 8.7.1.

So far everything is ok, vmime is found by configure. But when it comes to linking libkcinetmapi.a, the Script bails out:

It should be noted that Makefile.am notes the following for libkcinetmapi:

# Add '-z now' -> -Wl,-z, -Wl,now to LD flags so that we do early binding of
# symbols. This fixes a problem in which libvmime attempts to resolve a symbol
# in libinetmapi.so during the unload of vmime, initiated by the unload of
# libinetmapi. On some systems, this fails to resolve the symbol during unload,
# resulting in a crash in __cxa_finalize during unload of mapi.so
libkcinetmapi_la_LIBADD = \
        libmapi.la libkcutil.la libkcicalmapi.la \
        ${COND_libkcrosie_la} ${ICONV_LIBS} ${VMIME_LIBS} ${XML2_LIBS}

        -version-info 0:0:0 ${default_SYFLAGS${NO_VSYM}} -no-undefined
EXTRA_libkcinetmapi_la_DEPENDENCIES = ${default_sym}

As you can see, I have modified this passage (took away Wl,-z Wl,now; not supported by Cygwin; added --no-undefined for static linking). This might be the culprit, however, this worked with all the foregoing libraries very well.

When looking at the missing symbol: vmime::net::smtp::SMTPResponse::responseLine:getText() I tried to find it in /usr/lib64/libvmime.dll.a, but it is not there:

In the static library it is there:

However, linking to the static library does not lead to success.

Can anybody help me why this symbol is missing from the dll library?

A little patch can help:
