MySQL Bugs: #30118: Debug version of static client library on Windows lacks symbols

Bug #30118	Debug version of static client library on Windows lacks symbols
Submitted:	29 Jul 2007 11:50	Modified:	6 Aug 2007 21:33
Reporter:	Kent Boortz
Status:	Closed
Category:	C API	Severity:	S2 (Serious)
Version:	5.0.46	OS:	Microsoft Windows
Assigned to:	Kent Boortz	Target Version:

Description:
Trying to link an application with "lib\opt\mysqlclient.lib"
will show missing symbols, missing "zlib"

mysqlclient.lib(my_compress.obj) : error LNK2019: unresolved external symbol _compress
referenced in function _my_compress_alloc
mysqlclient.lib(my_compress.obj) : error LNK2019: unresolved external symbol _uncompress
referenced in function _my_uncompress

Linking with the debug version, "lib\debug\mysqlclient.lib" will show
it lacks "zlib" as well, but also it lacks "dbug"

mysqlclient.lib(libmysql.obj) : error LNK2019: unresolved external symbol __db_push_
referenced in function _mysql_debug@4
mysqlclient.lib(libmysql.obj) : error LNK2001: unresolved external symbol __no_db_
mysqlclient.lib(my_fopen.obj) : error LNK2001: unresolved external symbol __db_on_
.
.
.

How to repeat:
Try use the static library as stated in the User Manual. The "dbug.lib"
is not even part of the package, so no work around if need to use the
debug library. The work around for the static non debug packages is to
link with the bundled "zlib.lib" in addition to "mysqlclient.lib".

  make_win_bin_dist, CMakeLists.txt (many):
  
  - Made Windows client libraries pass linkage testing, both normal and
    debug libraries (bug#30118).
  
  - Made build closer to Unix build.
  
  - Removed code duplication.
  
  - Made separation between TLS and non TLS linkage clearer.
  
  - Removed redundant libraries from client linkage in the build itself,
    to force build errors when "mysqlclient.lib" is incomplete.

  CMakeLists.txt (several), make_win_bin_dist:
    Aligned client library build and use with the Unix version when it
    comes to what source to include directly in the builds, and what
    libraries to link with (bug#30118).
  
    Also reviewed, corrected and made more clear when static or dynamic
    Thread Local Storage is to be used. Some code duplication was removed,
    and some redundant library usage were removed, reducing the risk of
    incorrect TLS usage.

    Manual merge from 5.0 (bug#30118)
  CMakeLists.txt, mysqlbinlog.cc, lib_sql.cc:
    No need to test on USING_CMAKE, it is the only Windows build

  Re-apply fixes originally made by Kent, 
  they got lost because of a merge conflict with the CMakeLists.txt 
  dependency fix (numer 29982 in our bugs DB).

  CMakeLists.txt, README, configure.js
    Several adjustments to make client libraries pass the link test
    on both win32 and winx64, Visual Studio 2003 and 2005 (bug#30118)

Pushed into 5.1.21-beta

Pushed into 5.0.48

Noted in 5.0.48, 5.1.21 changelogs.

On Windows, client libraries lacked symbols required for linking.
