g++ ptypes compilation

[adam]

After successfull build of ptypes I create a catalog: my_ptypes_test on
ptypes root (like wshare) place there the code of multithreaded server
taken from
http://www.melikyan.com/ptypes/doc/async.examples.html
into file my_ptypes_test.cpp.

Compile command line:

g++ -pthread -D_GNU_SOURCE -DDEBUG -I../include -Wall -O2
.../lib/libptypes.a -o my_ptypes_test my_ptypes_test.cpp

brings a 8kb of "undefined reference to"

The output is the same when I remove ../lib/libptypes.a from command
line. But no info about libptypes.a fail to load and the file exist for
sure

please help! thx!

Libs should be last in the g++ command. Any libs not in
the standard locations (/usr/lib, etc) should have their
location specified with a '-L' switch. try something
like this:

g++ -pthread -D_GNU_SOURCE -DDEBUG -I../include -Wall -O2
-o my_ptypes_test my_ptypes_test.cpp -L../lib -lptypes

You may have to use the fully qualified path with the '-L'
switch (e.g. -L/home/me/stuff/lib).

See the gcc/g++ docs for details.
