Sockets, Threads, xHarbour and Linux

Hi all

I wanted to do some socket programming and was glad to see that the INet....() functions appear to be implemented in the Linux version of xHarbour. I tried to start with the examples given under the INetServer() function in the xHarbour documentation but note that StartThread() and WaitForThreads() are either not implemented or are in some library that I'm not linking or whatever.

Can anyone tell me how to manage threads under Linux with xHarbour?

Thanks

Doug,

You need a more recent xHarbour build. You can build it yourself from the xHarbour CVS or we can build it here and send it to you :-)

Doug,

These are the examples provided with xharbour:

Hi Antonio

Thanks for the prompt replies.

The mediafire link comes up (briefly) with a message that these are private files and won't let me access them.

Whilst I must learn one day to build xHarbour from the CVS, getting one built by you sounds good and guarantees compatability.

Thanks

Doug

Doug,

First of all you need to create a checkout.sh file with these contents:

checkout.sh

Code: Select all

cvs -d:pserver:anonymous@xharbour.cvs.sourceforge.net:/cvsroot/xharbour login
 
cvs -z3 -d:pserver:anonymous@xharbour.cvs.sourceforge.net:/cvsroot/xharbour co -P xharbour
Give it execution permissions: chmod +x ./checkout.sh

Then simply do: ./checkout.sh
xHarbour will start downloading to your computer, in the same folder where checkout.sh is

You may need to install CVS: sudo apt-get install cvs

Doug,

Once you have done the checkout, go to the created folder xharbour and change permissions of make_gnu.sh:

chmod +x ./make_gnu.sh

then simply do:

./make_gnu.sh

BTW, you need to have bison installed:
sudo apt-get install bison

Doug,

In the meantime, here you have again the thread examples, this time using rapidshare:

Didn't quite work

Doug,

The problem comes from odbc.c as it uses some header files that are not available, so as odbc.o is part of the rtl library, then it can't get built.

I remember that we had to install a package to get odbc support for Linux, but I have been looking in these forums and can't find it.

Hi Antonio

I can remember a reference to that package somewhere - I think in this forum. I will try to find it.

Thanks

Hi Antonio

This is from one of your early posts on this forum

Code: Select all

sudo apt-get install unixODBC-dev
Is that it?

Doug,

yes, thats it. Thanks! :-)

Also we may need unixodbc too.

Some Progress

Hi Antonio

I made some progress.

Installed unicODBC-dev. That automatically installed unixodbc also (amongst other things)

Reran make_gnu.sh but it falls over when in xharbour/source/rtl/linux/gcc and it tries to compile (gcc) strmatch.c with the following output:

Code: Select all

In file included from ../../strmatch.c:55:
../../../../include/hbapi.h:330: Warning: type qualifier ignored on function return type
../../strmatch.c: In function 'hb_strMatchFile':
../../strmatch.c:354 warning: implicit declaration of function 'fnmatch'
../../strmatch.c:354 error 'FNM_PERIOD' undeclared (first use in this function)
../../strmatch.c:354 error 'FNM_PATHNAME' undeclared (first use in this function)
make[3] *** [strmatch.o] Error 1
So something is still not quite right

Thanks

Doug,

fnmatch.h needs to be available:

Only possibly slight progress

Hi Antonio
downloaded fnmatch.h but didn't fix problem.

added #include "fnmatch.h" to strmatch.c

mak_gnu.sh falls over having entered utils/hbrun.

Regards

Doug
