CMake PkgConfig and ZLIB errors

[kimkulling]

I checked out the latest svn revision (1298), opened up CMake v2.8.9, pointed it to the assimp source code folder, hit "configure" and got the following output: Check for working C compiler using: Visual Studio 10 Check for working C compiler using: Visual Studio 10 -- works Detecting C compiler ABI info Detecting C compiler ABI info - done Check for working CXX compiler using: Visual Studio 10 Check for working CXX compiler using: Visual Studio 10 -- works Detecting CXX compiler ABI info Detecting CXX compiler ABI info - done Could NOT find PkgConfig (missing: PKG_CONFIG_EXECUTABLE) Boost version: 1.51.0 Looking for ZLIB...

Even the static lib version compiles. But when I try to link to the static lib, I get the following output: Warning 1 warning LNK4075: ignoring '/INCREMENTAL' due to '/LTCG' specification Warning 2 warning LNK4098: defaultlib 'LIBCMT' conflicts with use of other libs; use /NODEFAULTLIB:library Error 3 error LNK2001: unresolved external symbol _inflateEnd assimpD_static.lib(XGLLoader.obj) Error 4 error LNK2001: unresolved external symbol _inflateEnd assimpD_static.lib(BlenderLoader.obj) Error 5 error LNK2001: unresolved external symbol _inflateEnd assimpD_static.lib(unzip.obj) Error 6 error LNK2001: unresolved external symbol _inflateEnd assimpD_static.lib(XFileParser.obj) Error 7 error LNK2001: unresolved external symbol _inflate assimpD_static.lib(XGLLoader.obj) Error 8 error LNK2001: unresolved external symbol _inflate assimpD_static.lib(BlenderLoader.obj) Error 9 error LNK2001: unresolved external symbol _inflate assimpD_static.lib(unzip.obj) Error 10 error LNK2001: unresolved external symbol _inflate assimpD_static.lib(XFileParser.obj) Error 11 error LNK2001: unresolved external symbol inflateInit2 assimpD_static.lib(XGLLoader.obj) Error 12 error LNK2001: unresolved external symbol inflateInit2 assimpD_static.lib(BlenderLoader.obj) Error 13 error LNK2001: unresolved external symbol inflateInit2 assimpD_static.lib(unzip.obj) Error 14 error LNK2001: unresolved external symbol inflateInit2 assimpD_static.lib(XFileParser.obj) Error 15 error LNK2001: unresolved external symbol _get_crc_table assimpD_static.lib(unzip.obj) Error 16 error LNK2001: unresolved external symbol _crc32 assimpD_static.lib(unzip.obj) Error 17 error LNK2001: unresolved external symbol _inflateSetDictionary assimpD_static.lib(XFileParser.obj) Error 18 error LNK2001: unresolved external symbol _inflateReset assimpD_static.lib(XFileParser.obj) Error 19 error LNK1120: 7 unresolved externals This leads me to believe that zlib was not properly linked into assimp.lib, since most of those are zlib functions and the CMake output said it failed to find zlib. This occurs on a Windows 7 64-bit machine (compiling for 32-bit) in VC10. If there is a way I could fix this, please let me know!

I know this issue is exactly 1 year old, but if anyone is having similar issues, setting "Link Library Dependencies" to Yes in "Assimp Project Properties > Librarian > All Options" and rebuilding will solve it.

i met a similar issue a few days ago. when i use cmake to configure, it can find ZLIB which is carried by cmake. but when i build the sln , i get the same output, the same error. after i tryed the solution of above, it didn't work .So i deleted the ZLIB of my computer and let cmake to compiling ZLIB from source, it work.The error disappear! (i used the version 3.1.1)

I am facing another issue, that is solution is compiling successfully. But I am unable to find the build libraries. It is not found in the "Win32/Debug" folder. I am using the latest 4.0.1 version. And also while creating "sln" file I am facing following error:-

If you build the sln successfully,you will find the library by the follow path:..\code\Release....You will see the assimp.dll assimp.lib
