Building Eterm - please more help

Wed Oct 30 19:17:00 GMT 2002

Robert,

Well, eterm's libast is contains the file that is being put in 
/usr/local/include/libast.h... and that file has had the following code 
as far back as the CVS history goes:

#*if* *defined*(PATH_MAX) && (PATH_MAX < 255)
#  *undef* PATH_MAX
#*endif*
#*ifndef* PATH_MAX
#  *define* PATH_MAX 255
#*endif

Now, I cannot say that the (PATH_MAX < 255) conditional is actually going to mean
anything to the C preprocessor that we use, and I will bet you money that this
just breaks differently on other platforms such that PATH_MAX is not being
redefined (it is probably never defined on those platforms).

In any case, I am going to have to tell you the secret that makes all of us
``hackers'' real men.  Okay, the secret is, when something in a header conflicts
with a system header, you do three things:

1) #if 0 the section in the offending header that redefines what the system
headers defines.

2) Do a test compile and see if the point of error moves on to some other point.

3) If you succeed at #2, then go back and either fix the broken #define code
or add a platform-specific kludge that prevents that section from doing
harm on your platform.

That is how we get things compiled, and some of us go back and clean the mess up
later so that the changes can actuall be committed so CVS.  :)

There, you are now much wiser, and I think you know that I am trying to tell you
to do next, right?

Harold

P.S.  Okay, just in case, goto /usr/local/include/libast.h and #if 0 the section
that I quoted above.  Rebuild.  If the build still fails, go look again at
/usr/local/include/libast.h and make sure that it has not been replaced with
an original version during the build process; in which case you would need
to edit the version of libast.h in your source tree (which you will eventually have
to do anyway).
