Title: Can't link wx xml module
Post by: DanRR on October 01, 2008, 04:47:39 pm

I've created wx project with Unicode monolithic build. The compiler is MinGW (on Windows).
wxWidgets version is 2.8.7 (I'm using the prebuild wxPack) .
My project uses wx xml module (wx/xml/xml.h header).
The project won't link, issuing the following errors:

C:\wxWidgets2.8.7\lib\gcc_lib\libwxmsw28u.a(monolib_xml.o):xml.cpp:(.text+0x3510)||undefined reference to `_XML_ParserCreate'|

I added libwxbase28u_xml.a to the Release build, but got the same errors.

What should I do to link it?
Thanks

Also add libwxexpat.a.

Thanks! it worked.
BTW, how can you determine which library files do you need in a wx project?

Documentation, a knowledge of the library's internals, and/or trial and error.
