@ Phil and Laurent: Yes, we are using the absolutely latest official CMake wxWidgets find module that is heavily maintained by the CMake developers. So I doubt there are any obvious bugs in that find module. @Laurent: My apologies for not answering sooner but I was otherwise occupied with other issues currently being discussed on the PLplot devel list. The short explanation of the message you were getting is that our build system gets a list of libraries from the official find module. Some of those are actual locations, and some are in the -L...-l... form. So we transform the latter to actual location by looking for the library using the find_library command, and for some reason some of those could not be found. The cure for this is to identify the libraries that were not found from comparing the old and transformed lists, then installing the relevant libraries or adjust environment variables such as PATH and/or CMAKE_LIBRARY_PATH to help CMake find the relevant libraries. I must say, however, that the comparison of the two lists given to you is a far less than optimal way to find what libraries could not be found so I plan in the next few days to update that part of our build system to make this WARNING message a lot clearer. For now, though, you are stuck with correlating the following two lists (i.e., search for a NOTFOUND result on the second list and find from its position what -l form it corresponded to in the orignal list) to find what libraries are missing. >> cmake_link_flags WARNING: (original link flags) = >> -L/f/lib/wxWidgets-3.1.0/lib;;;-Wl,--subsystem,windows;-mwindows;/f/lib/wxWidgets-3.1.0/lib/libwx_mswu_core-3.1.a;/f/lib/wxWidgets-3.1.0/lib/libwx_baseu-3.1.a;-lwxregexu-3.1;-lwxexpat-3.1;-lwxtiff-3.1;-lwxjpeg-3.1;-lwxpng-3.1;-lz;-lrpcrt4;-loleaut32;-lole32;-luuid;-lwinspool;-lwinmm;-lshell32;-lshlwapi;-lcomctl32;-lcomdlg32;-ladvapi32;-lversion;-lwsock32;-lgdi32 >> >> cmake_link_flags WARNING: wxwidgets_LINK_FLAGS = >> -Wl,--subsystem,windows;-mwindows;/f/lib/wxWidgets-3.1.0/lib/libwx_mswu_core-3.1.a;/f/lib/wxWidgets-3.1.0/lib/libwx_baseu-3.1.a;_library_pathname-NOTFOUND;_library_pathname-NOTFOUND;_library_pathname-NOTFOUND;_library_pathname-NOTFOUND;_library_pathname-NOTFOUND;F:/mingw-w64/Strawberry/c/lib/libz.a;C:/Windows/System32/rpcrt4.dll;C:/Windows/System32/oleaut32.dll;C:/Windows/System32/ole32.dll;_library_pathname-NOTFOUND;_library_pathname-NOTFOUND;C:/Windows/System32/winmm.dll;C:/Windows/System32/shell32.dll;C:/Windows/System32/shlwapi.dll;C:/Windows/System32/comctl32.dll;C:/Windows/System32/comdlg32.dll;C:/Windows/System32/advapi32.dll;C:/Windows/System32/version.dll;C:/Windows/System32/wsock32.dll;C:/Windows/System32/gdi32.dll To make the explanation simpler, let me break down both lists at the semicolons: That means original = -L/f/lib/wxWidgets-3.1.0/lib; ; ; -Wl,--subsystem,windows; -mwindows; /f/lib/wxWidgets-3.1.0/lib/libwx_mswu_core-3.1.a; /f/lib/wxWidgets-3.1.0/lib/libwx_baseu-3.1.a; -lwxregexu-3.1; -lwxexpat-3.1; -lwxtiff-3.1; -lwxjpeg-3.1; -lwxpng-3.1; -lz; -lrpcrt4; -loleaut32; -lole32; -luuid; -lwinspool; -lwinmm; -lshell32; -lshlwapi; -lcomctl32; -lcomdlg32; -ladvapi32; -lversion; -lwsock32; -lgdi32 Transformed = -Wl,--subsystem,windows; -mwindows; /f/lib/wxWidgets-3.1.0/lib/libwx_mswu_core-3.1.a; /f/lib/wxWidgets-3.1.0/lib/libwx_baseu-3.1.a; _library_pathname-NOTFOUND; _library_pathname-NOTFOUND; _library_pathname-NOTFOUND; _library_pathname-NOTFOUND; _library_pathname-NOTFOUND; F:/mingw-w64/Strawberry/c/lib/libz.a; C:/Windows/System32/rpcrt4.dll; C:/Windows/System32/oleaut32.dll; C:/Windows/System32/ole32.dll; _library_pathname-NOTFOUND; _library_pathname-NOTFOUND; C:/Windows/System32/winmm.dll; C:/Windows/System32/shell32.dll; C:/Windows/System32/shlwapi.dll; C:/Windows/System32/comctl32.dll; C:/Windows/System32/comdlg32.dll; C:/Windows/System32/advapi32.dll; C:/Windows/System32/version.dll; C:/Windows/System32/wsock32.dll; C:/Windows/System32/gdi32.dll The empty list elements in the first list are simply ignored. But from the above broken down versions, I hope it is now clear that you have to install (or help CMake find) the libraries corresponding to -lwxregexu-3.1; -lwxexpat-3.1; -lwxtiff-3.1; -lwxjpeg-3.1; -lwxpng-3.1; and -luuid; -lwinspool; in the first list which ended up as _library_pathname-NOTFOUND; (i.e., the corresponding library from the first list could not be found) in the transformed list.
