[Gmsh] Can Gmsh be compiled as .lib file?

[rakesh patil]

Hi Laurent,

This is what I did. As mentioned by you, I configured gmsh in CMAKE with
visual studio 2008 (win 64) compiler. I disabled BLOSSOM and FLTK and gave
the appropriate paths for BLAS and LAPACK libraries (I am using BLAS and
LAPACK libraries which comes along with Intel Compiler). I was able to
build static and dynamic libraries both. But when I linked them with my
application, I got following run time error:

Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol send
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol
WSAStartup
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol
WSACleanup
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol
closesocket
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol connect
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol htons
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol
gethostbyname
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol socket
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol recv
Gmsh.lib(GmshMessage.obj): error LNK2001: unresolved external symbol select
Gmsh.lib(OS.obj): error LNK2001: unresolved external symbol gethostname

Well, I observed that these functions are available in the code, but still
wondering why my application is not able to link them. Is there any
pre-processor to be defined before compiling? Or is it because I'm trying
to build gmsh for 64-bit windows machine?

Thanks
