Including a static library

[jepessen]

Hi.
I'm trying to add an external library (libmesh) to a project that must be created under Linux environment.

I've downloaded and compiled the library myself, so it's in a not standard location. The location is in

mydir/lib/libmesh.so

while headers are located in

mydir/include

in this directory I've many subfolders (base, geom etc).

The first thing that I'd like to know is how I can include all include subfolders without declare a INCLUDEPATH for everyone, but telling that I want to use all subfolders of mydir/include.

Then, I'd like to know how include the .so file in my project.

I've tried to use

LIBS += $$quote(mydir/lib/libmesh.so)

and

LIBS += -L$$quote(mydir/lib/libmesh.so)

but nothing happens: I got a lot of "undefined reference" errors.

Have you any suggestion?

For include subdirs try with

SUBPATH = $$system(ls include)
for(d, SUBPATH):INCLUDEPATH += include/$$d

SUBPATH = $$system(ls include)
for(d, SUBPATH):INCLUDEPATH += include/$$d

To copy to clipboard, switch view to plain text mode 

The correct syntax for libraries is

LIBS += -L$$quote(mydir/lib) -lmesh

LIBS += -L$$quote(mydir/lib) -lmesh

To copy to clipboard, switch view to plain text mode

If the library file you wish to link against has a name ending in .so then it is a dynamic library, not a static library which would end in .a. If both dynamic and static versions of the library exists, then the linker will usually take the dynamic library by default.

Thanks for our reply.

I've seen the QMake documentation and I've seen some example. Thanks. I've another problem, but I'll put it in another thread.
Thanks again to everyone.
